Answers

Answer 1

The oxidation number of H is -1.

Sum of the oxidation numbers in each element = charge of the complex

CaH₂ has 1 Ca atom and 2H atoms. The charge of the complex is zero. Let’s say Oxidation number of H is "a".

Then,

    (+2) + 2 x a = 0

        +2  + 2a  = 0

                  2a = -2

                    a = -1

Hence, the oxidation number of Hydrogen atom in CaH₂ is -1


Answer 2
Final answer:

In the compound CaH2, calcium has an oxidation number of +2, and hydrogen has an oxidation number of -1, balancing the charges. The oxidation states of elements in a compound like CaH2 influence their properties and reactivity.

Explanation:

In the compound CaH2, calcium has an oxidation number of +2 and hydrogen has an oxidation number of -1.

Hydrogen usually has an oxidation number of +1 except when bonded to metals in hydrides where it is -1. This is the case in compounds like CaH2.

Each hydrogen atom in CaH2 carries a charge of -1, balancing with the +2 charge of calcium to maintain overall charge neutrality.

What is the main similarity among elements in group 2?

Answers

Answer:
             Chemical Properties

Explanation:
                   Elements belonging to same group in a periodic table have same chemical properties. This similarity in chemical properties arises mainly from the same number of valence shell electrons. Group 2 elements also called Alkaline Earth Metals have two valence electrons in their valence shell with following electronic configuration....

                                                       ns²

Where "n" represents principle quantum number or number of main shell.

The reactivity of these elements is due to the metallic behavior as these elements looses two electrons to form a cation with +2 oxidation number. i.e.

                                          X   →   X⁺²  +  2 e⁻

Therefore, all elements present on Group II will form a cation with +2 oxidation number and behave in the same manner with different reagents.

Determine the oxidation state of the metals in pbcro4. 1. pb = +1, cr = +4 2. pb = +2, cr = +4 3. pb = +2, cr = +6 4. pb = +1, cr = +1 5. pb = +1, cr = +6

Answers

PbCrO₄ is made of a cation and anion
anion is CrO₄²⁻
we need to then find the oxidation number of Pb which is the same as its charge
when we make compounds, the charges of the cations and anions are exchanged.
Charge of Pb is then Pb²⁺
since charge of monoatomic ion is equal to oxidation number of the ion
oxidation number of Pb = +2
net charge of CrO₄²⁻ is -2
oxidation number of Cr + (4 x oxidation number of O) = -2
oxidation number of O is usually -2
oxidation number of Cr = y
y + (4 x -2 ) = -2
y - 8 = -2
y = +6
oxidation number of Cr is +6

answer is 
3. pb = +2, cr = +6

The oxidation state of the lead and chromium metal in the PbCrO₄ compound is +2 and +6 respectively.

What is oxidation state?

Oxidation state of any atom tells about the number of exchangeable electrons from the outermost shell of that atom.

As we know that in the compound PbCrO₄, CrO₄ is an anion and charge on this is -2 i.e. it is represented as CrO₄²⁻. We know that oxidation state of each oxygen atom is -2 and let us assume the oxidation state of chromium is y, so we calculate the value of y for CrO₄²⁻ as:

y + 4(-2) = -2

y = -2 + 8 = 6

Let the oxidation state of lead is x and calculation for that from PbCrO₄ will be done as:

x + 6 + 4(-2) = 0

x = 8 - 6 = 2

Oxidation state of Pb is +2 and of Cr is +6.

Final answer:

To calculate the number of atoms, molecules, or moles, we use Avogadro's number (6.02 × 10²³). There are 6.02 × 10²³ atoms in 0.60 mol of zinc. Dividing the number of molecules by Avogadro's number gives us the moles for each compound in the problems posed.

Explanation:

To solve these types of problems, we use Avogadro's number (6.02 × 10²³), which is the number of units in one mole of any substance. This can be atoms, ions, or molecules, depending on the context of the substance in question.

Answers:

There are 6.02 × 10²³ atoms of zinc in 0.60 mol of zinc.To find how many moles 3.52 × 10²⁴ molecules of water represents, divide by Avogadro's number: 3.52 × 10²⁴ molecules ÷ (6.02 × 10²³ molecules/mol) ≈ 5.84 mol of water.For lithium, there are 2 × 6.02 × 10²³ atoms in 2.00 moles of Li, since 1 mol of any element contains exactly 6.02 × 10²³ atoms by definition.Having 6.02 × 10²³ atoms of carbon means you have 1 mole of carbon, as 1 mol is equivalent to Avogadro's number of atoms.To determine the number of moles in 4.9 × 10²³ molecules of ZnCl₂, divide by Avogadro's number: 4.9 × 10²³ molecules ÷ 6.02 × 10²³ molecules/mol ≈ 0.814 mol of ZnCl₂.

Answers

Following are the molecules of interest H2O, NH3 and CH4.

For example, in H2O, oxygen undergoes sp3 hydridization
in case of NH3, nitrogen underdoes sp3 hybridization,
and in case of CH4, methane undergoes sp3 hydridization.

Followed by hybridization, the hybridized orbitals are unsymmetrically occupied in case of H2O and NH3. In water, two hybridized  orbitals are occupied by H atom and remaining two orbitals contain lone pair of electrons. In case of NH3, three hybridized orbitals are utilized for bonding with H atom, while one hybridized orbital contain lone pair of electron. In contrast to this, in case of methane all the four hybridized orbitals are utilized for bonding with hydrogen. Thus, methane is symmetrically substituted in contrast to water and ammonia. Due to this,  there is the uneven distribution of bonding electrons in H2O and NH3, thereby creating a partially positive and negative sides of that molecule.

Which substance would be least likely to dissolve in a polar solvent?

Answers

Final answer:

Octane (C8H18) and naphthalene are nonpolar substances and would be least likely to dissolve in a polar solvent like water. Methanol (CH3OH), sodium sulfate (Na2SO4), LiCl, and benzoic acid (CH2CO2H) are polar or ionic and would more readily dissolve.

Explanation:

To predict which substance would be least likely to dissolve in a polar solvent like water, one must consider the polarity of the molecules involved. In general, "like dissolves like," which means that polar solvents will dissolve polar substances and nonpolar solvents will dissolve nonpolar substances.

Methanol (CH3OH) and sodium sulfate (Na2SO4) are polar and will likely dissolve in water due to their ability to create intermolecular hydrogen bonds and ionic interactions, respectively. On the other hand, octane (C8H18) is nonpolar, consisting mostly of C-H bonds, and would have the least tendency to dissolve in a polar solvent due to dispersion forces being the primary intermolecular interaction.

Considering LiCl, benzoic acid (CH2CO2H), and naphthalene, LiCl and benzoic acid are more likely to dissolve in water due to their ionic and polar nature, respectively, while naphthalene, being nonpolar, would be the least likely to dissolve.

Midpoint formula: (x1 + x2)/2, (y1 + y2)/2, where (x1, y1) and (x2, y2) are the endpoints of the segment 

x-coordinate of midpoint = (x1 + x2)/2 
5 = (1 + x2)/2 
10 = 1 + x2 
9 = x2 

y-coordinate of midpoint = (y1 + y2)/2 
3 = (-5 + y2)/2 
6 = -5 + y2 
11 = y2 

Final answer:

The coordinates of the other endpoint, H, can be calculated using the midpoint formula: Endpoint = (2 x Midpoint) - Known Endpoint. Applying this formula, we find that the coordinates of endpoint H are (9, 11).

Explanation:

The subject of this question is Mathematics, specifically coordinate geometry. Given the midpoint M(5,3) and one endpoint G(1,-5), we're asked to find the coordinates of the other endpoint, H. The formula to find the coordinates of an endpoint when given the midpoint and another endpoint is as follows:

Endpoint = (2 x Midpoint) - Known Endpoint

So, applying this formula, we find H to be:

H = (2x5 - 1, 2x3 - (-5)) = (9, 11).

So the other endpoint H is at (9, 11).

Given the equation zn(s) + 2 hcl(aq) → zncl2(aq) + h2(g), what mass of hydrogen gas is produced when 2.8 g zn is reacted with excess aqueous hydrocholric acid?

Answers

Final answer:

To calculate the mass of hydrogen gas produced, we use stoichiometry of the chemical reaction between Zn and excess HCl. After determining moles of Zn from the given mass, we find the moles of H2, which is equal due to the 1:1 molar ratio, and then multiply by the molar mass of H2 to get 0.0863 g of hydrogen gas.

Explanation:

Calculating the Mass of Hydrogen Gas

To calculate the mass of hydrogen gas produced when 2.8 g of Zn is reacted with excess hydrochloric acid (HCl), we will use the stoichiometry of the balanced chemical reaction: Zn(s) + 2 HCl(aq) → ZnCl₂ (aq) + H₂(g). The reaction shows that one mole of Zn produces one mole of H2. First, we find the molar mass of Zn, which is approximately 65.38 g/mol.

Step 1: Calculate the moles of Zn.

Moles of Zn = (mass of Zn) / (molar mass of Zn) = 2.8 g / 65.38 g/mol = 0.0428 mol

Step 2: Determine the moles of H2 formed using the molar ratio from the balanced equation (1:1).

Moles of H2 = Moles of Zn = 0.0428 mol

Step 3: Calculate the mass of H2 using the molar mass of H2 (approximately 2.016 g/mol).

Mass of H2 = Moles of H2 × Molar mass of H2 = 0.0428 mol × 2.016 g/mol = 0.0863 g

Therefore, the mass of hydrogen gas produced is 0.0863 g.

The poh of a solution is 9.32. calculate the hydrogen ion concentration of the solution.

Answers

Final answer:

To find the hydrogen ion concentration from the pOH value of 9.32, we first calculate the pH as 4.68. We then use the relationship [H3O+] = 10^-pH to find the hydronium ion concentration, which is approximately [tex]2.09 × 10^-5 M.[/tex]

Explanation:

The student asked about calculating the hydrogen ion concentration of a solution from its pOH. The pOH of a solution is 9.32, and we want to find the [H3O+]ion concentration, also written as [H+].

The relationship between pH, pOH, and ion concentrations in water at 25 °C is given by the equation:

pH + pOH = 14

From the given pOH value, we can find the pH:

pH = 14 - pOH

pH = 14 - 9.32 = 4.68

Once we have the pH, we can calculate the hydronium ion concentration using the inverse of the logarithmic relationship:

[H3O+] = 10-pH

[H3O+] = 10-4.68

The final hydrogen ion concentration, or hydronium ion concentration, is therefore approximately 2.09 × 10-5 M.

Which will dissolve faster in water one gram cube of sugar or one gram of powder sugar?

Answers

the  powder sugar because has more contact area 

Powdered sugar dissolves faster than a cube of sugar because it has a greater surface area, which increases the frequency of collisions between the sugar particles and water molecules, hence speeding up the dissolving process.

In the comparison of a one gram cube of sugar and one gram of powdered sugar dissolving in water, the powdered sugar will dissolve faster. This phenomenon is because dissolving is a surface-driven process where solvent molecules collide with the surface of the solute.

The powdered sugar has a greater surface area exposed to the water, increasing the opportunity for these collisions to occur, which enhances the rate of dissolution. Moreover, stirring the solution can increase the rate at which both the powdered and the cube sugar dissolve. However, since the cube has less surface area exposed compared to powdered sugar, the powdered form will still dissolve more quickly, even with agitation.

The speed at which the sugar dissolves isn't dependent on the type of sugar since both forms have the same chemical composition, but rather on the physical form of the sugar which affects the overall surface area available for dissolution.
