Calcite (the main mineral in limestone) is made of calcium carbonate (CaCO3). Dolomite, a related mineral, is made of magnesium carbonate (MgCO3). What happens if a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite?

Answers

Answer 1

Answer: CO₂ will be formed, with the consequent fizzing effect.

Explanation:

1) Look at the chemical reaction that happens between magnesiumm carbonate and vinegard

MgCO₃(aq) + CH₃COOH(l) → CO₂ (g) + MgCOOH(aq) (it is not balance as it is only to show the products formed not to make calculations).

2) Then you see that CO₂ is evolving in the form of gas. That will cause the formation of bubbles (fizzing).

Answer 2

Dolomite is an anhydrous magnesium carbonate mineral that reacts with acetic acid (vinegar) to produce fizzing because of the carbon dioxide gas produced.

What is effervescence?

Effervescence is a fizz or release of bubbles of gases when it reacts with another substance. Carbon dioxide is released with a fizzing effect.

The reaction between dolomite and vinegar is shown as:

[tex]\rm MgCO_{3}(aq) + 2 CH_{3}COOH(l) \rightarrow CO_{2} (g) + H_{2}O + Mg(CH_{3}COO)_{2}[/tex]

From the reaction, it can be said that the release of carbon dioxide results in effervescence or fizz.

Therefore, a drop of acetic acid on dolomite results in effervescence.

When an arrhenius base is dissolved in h2o, the only negative ion present in the solution is?

Answers

Answer is: hydroxide ions (OH⁻).
An Arrhenius base is a substance that dissociates in water to form hydroxide ions (OH⁻).
For example sodium hydroxide: NaOH(aq) → Na⁺(aq) + OH⁻(aq) or barium hydroxide: Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻(aq).
According to this theory acids are substances which produce hydrogen ions in water solution.

If 2500. J of energy are added to 120. g of benzene at 30. degrees C, what will be its final temperature?

Answers

When heat (q) is absorbed by "m" grams of a substance then the change in temperature is given as,

q = m Cp (T₂ - T₁) --- (1)

where;
Cp = Specific Heat

Specific heat of Benzene is 1.72 J/g.°C

Now,
Solving equation 1,

(T₂ - T₁) = q / m Cp
Putting values,
(T₂ - 30 °C) = 2500 J ÷ (120 g ×1.72 J/g.°C)

(T₂ - 30 °C) = 2500 J ÷ (206 J/°C)

(T₂ - 30 °C) = 12.13 °C

T₂ = 12.13 °C + 30 °C

T₂ = 42.13 °C

The final temperature of benzene after adding 2500 J of energy is 41.97°C.

To determine the final temperature of benzene after adding 2500 J of energy, we can use the formula for specific heat capacity:

q = mcΔT

Where:

q is the heat added (2500 J)m is the mass of benzene (120 g)c is the specific heat capacity of benzene (1.74 J/g°C)ΔT is the change in temperature

Rearranging the formula to solve for ΔT:

ΔT = q / (mc)

Substitute the given values:

[tex]\Delta T = \frac{2500 \, \text{J}}{120 \, \text{g} \times 1.74 \, \text{J/g \textdegree C}}\\\\\Delta T = \frac{2500 \, \text{J}}{208.8 \, \text{J/°C}} \approx 11.97 \textdegree C[/tex]

Add this change to the initial temperature of 30°C:

Final temperature = 30°C + 11.97°C = 41.97°C

Therefore, the final temperature of the benzene after adding 2500 J of energy is 41.97°C.

How many grams of titanium (Ti, 47.90 g/mol) are in an instrument gear with 5.74x10^22 atoms of Ti

Answers

Answer:
Mass = 45.64 g

Solution:

First of all calculate number of moles for given number of atoms,

As,
6.022 × 10²³ atoms = 1 Mole
So,
5.74 × 10²² atoms = X Moles

Solving for X,
X = (1 mol × 5.74 × 10²² atoms) ÷ 6.022 × 10²³ atoms

X = 0.953 Moles

Now converting moles into mass,
As,
Moles = Mass / M.mass
So,
Mass = Moles × M.Mass
Putting Values,
Mass = 0.953 mol × 47.90 g.mol⁻¹

Mass = 45.64 g

Answer:

what temperature does blood boil at (in Celsius Kelvin and Fahrenheit)

Answers

where temperature is measured in Kelvin (Kelvin = Celsius + 273.15). For example, 1L of blood at 1 ATM boils at 373.15 Kelvin. If you doubled the atmospheric pressure, the blood would boil at 746.3 Kelvin, or 473.15 Celsius. Blood boils at approximately the same temperature as water, around 100 degrees centigrade.

Blood boils at a temperature close to water's boiling point: 100°C, 373 K, or 212°F. This boiling point slightly varies due to dissolved substances. Understanding these values illustrates the relationship among different temperature scales.

When considering the temperature at which blood boils, it primarily depends on its composition, but generally, it is close to the boiling point of water. The boiling point of water is an important reference and is commonly known for each temperature scale:

Celsius (°C): Water boils at 100°C.Kelvin (K): Water boils at 373 K.Fahrenheit (°F): Water boils at 212°F.

Human blood is mostly water, and hence its boiling point is similarly close; however, due to the presence of dissolved proteins, salts, and other substances, the exact boiling point may slightly vary. At normal atmospheric pressure, it is approximately 100°C (373 K or 212°F). This concept is an important illustration of the relationship among the temperature scales.

Answers

the balanced equation for the acid base reaction is as follows
Ca(OH)₂ + 2HCl ---> CaCl₂ + 2H₂O
stoichiometry fo Ca(OH)₂ to HCl is 1:2
number of HCl moles reacted - concentration of HCl x volume
number of HCl moles - 0.225 mol/L x 26.85 x 10⁻³ L = 6.041 x 10⁻³ mol
according to molar ratio
2 mol of HCl reacts with 1 mol of Ca(OH)₂
therefore 6.041 x 10⁻³ mol of HCl reacts with - 6.041 x 10⁻³ /2 mol = 3.021 x 10⁻³ mol
number of Ca(OH)₂ moles in 10.0 mL - 3.021 x 10⁻³ mol
therefore Ca(OH)₂ moles in 1000 mL - 3.021 x 10⁻³ mol / (10.0 x 10⁻³ L) = 0.302 mol/L
molarity of Ca(OH)₂ - 0.302 M

Final answer:

To calculate the molar concentration of the base, use stoichiometry and the given volume and concentration of the acid. The balanced chemical equation helps determine the moles of acid and base. Divide the moles of base by the volume of the base solution to find the molar concentration.

Explanation:

To calculate the molar concentration of the base, we can use the stoichiometry of the neutralization reaction between calcium hydroxide (Ca(OH)2) and hydrochloric acid (HCl). The balanced chemical equation for this reaction is:

Ca(OH)2 + 2HCl → CaCl2 + 2H2O

From the equation, we can see that 1 mole of Ca(OH)2 reacts with 2 moles of HCl. We are given that 26.85 mL of 0.225 M HCl is required to neutralize a 10.0 mL solution of Ca(OH)2. The moles of HCl can be calculated using the equation:

moles of HCl = volume of HCl (L) × concentration of HCl (M)

Once we have the moles of HCl, we can use the stoichiometry of the reaction to calculate the moles of Ca(OH)2. Finally, we divide the moles of Ca(OH)2 by the volume of the Ca(OH)2 solution to find the molar concentration.

What volume of hydrogen will be produced at STP by the reaction of 78.33g of aluminum with excess water

Answers

This problem can be solved in a simplest way, without using Ideal Gas Equation and lengthy calculations.

The balance chemical equation is,

2 Al + 6 H₂O → 2 Al(OH)₃ + 3 H₂

Remember at STP 1 mole of any gas exactly occupies 22.4 L volume.
So,
54 g (2 mole) Al on reaction produces = 67.2 L (3 mole) H₂
Then,
78.33 g of Al will produce = X L of H₂

Solving for X,
X = (78.33 g × 67.2 L) ÷ 54 g

X = 97.47 L of H₂ Gas

Final answer:

To find the volume of hydrogen gas produced at STP from the reaction of 78.33g of aluminum with excess water, calculate the moles of aluminum, convert that to moles of hydrogen gas using stoichiometry, and then use the molar volume at STP to find 97.44 liters of hydrogen gas.

Explanation:

To determine the volume of hydrogen produced at STP (Standard Temperature and Pressure) by the reaction of aluminum with excess water, we first need to write the balanced chemical equation for the reaction.

For aluminum reacting with water yielding aluminum hydroxide and hydrogen gas, the balanced equation is:

2 Al(s) + 6 H₂O(l) → 2 Al(OH)3(aq) + 3 H₂(g)

From this equation, we can see that 2 moles of aluminum produce 3 moles of hydrogen gas. To find the moles of aluminum in 78.33g, we use the molar mass of aluminum (approximately 26.98 g/mol).

Calculate the number of moles of aluminum:
78.33 g Al × (1 mole Al / 26.98 g Al) = 2.90 moles Al.Use stoichiometry to find moles of hydrogen gas formed:
2.90 moles Al × (3 moles H₂ / 2 moles Al) = 4.35 moles H₂.Calculate the volume of hydrogen gas at STP:
At STP, 1 mole of any gas occupies 22.4 liters. Therefore, the volume of hydrogen gas produced is:
4.35 moles H₂ × 22.4 L/mole = 97.44 L of H₂.

Thus, the reaction of 78.33g of aluminum with excess water will produce 97.44 liters of hydrogen gas at STP.

Write a general word equation for a neutralization reaction.

Answers

Hydrochloric acid + Sodium hydroxide =Sodium chloride +water

Final answer:

In a neutralization reaction, an acid reacts with a base to form salt and water, and the net ionic equation for this reaction usually involves hydrogen ions from the acid joining with hydroxide ions from the base to form water.

Explanation:

A general word equation for a neutralization reaction is: Acid + Base → Salt + Water

During neutralization, the hydrogen ions from the acid react with the hydroxide ions from the base to form water. The remaining ions (from the acid and base) then combine to form a salt. If we consider the neutralization of a strong acid with an ionic hydroxide, the net ionic equation simplifies to:

H3O+ (aq) + OH−(aq) → 2H2O(l)

This equation represents the concentration of hydrogen ions from the acid reacting with hydroxide ions from the base, simplifying down to just the formation of water since strong acids completely dissociate in water.
