Why hello there, Lithommie
Your question: can someone explain to me what happens when thermal energy is added to a state of matter?
My answer:
Very good question
lets take a look at what happens when thermal energy is added to a state of matter.
In this case lets look at a football game, at the beginning of the game the players represent the state SOLID the scores 0-0 and the heat is on. Remember the players are solid and when they are melting into a liquid by the end of the game and the players are mixing through the field and collapsing with one another and by the end of the game they become liquid.
Do you understand more clearfully? If you add heat to ice( the solid ) it melts and becomes water( The liquid )

Which of these four liquids is a mixture, made up of parts, some of which can be separated by flirtation? a. Salt water b. Skimmed milk c. Orange juice with pulp d. Distilled water
Orange juice with pulp is the correct answer because it is a heterogeneous mixture with suspended particles that can be separated by filtration.
Explanation:The question asks to identify which of the four liquids listed is a mixture that can be separated by filtration. Among the options provided:
Salt water is a homogeneous mixture, known as a solution, where the salt is completely dissolved in the water and cannot be separated by filtration.Skimmed milk is a colloid where the particles are larger than those in a solution but remain dispersed and do not settle, and thus also cannot be easily separated by filtration.Orange juice with pulp is a heterogeneous mixture that has suspended particles (pulp) which can be separated through filtration.Distilled water is not a mixture at all but a pure substance with a uniform and definite compositionTherefore, the liquid that is a mixture and can have some of its parts separated by filtration is orange juice with pulp.

As you pass a magnet over a blackish-yellow powder on a glass plate, black particles separate from the powder and become attached to the magnet. After a few passes of the magnet over the powder nothing but a yellow powder remains in the glass plate. The original blackish-yellow powder was:
AS given that we have started with a solid powder on a glass plate which appears to be blackish yellow, on passing magnet the black particles separated.
so the black particles are magentic in nature. however the yellow portion of powder is not magnetic or diamagnetic
so its clear that we are able to separate the black and yellow portions by simple physical methods.
If we are able to separate any two substances by simple physical methods then it means that the powder is a mixture and not a compount
A fertilizer is 60.9% ammonium phosphate. What is the percent P in the sample? Answer in units of %
I originally got 20.7685% but it says my answer is wrong. Help?
Answer:- 12.7%
Solution:- It says, ammonium phosphate is 60.9%. It means if we assume 100 g of the sample then there is 60.9 g ammonium phosphate in it.
Formula of ammonium phosphate is [tex](NH_4)_3PO4[/tex] and it's molecular weight is 149 grams per mol. There is only one P in the formula and so the mass of P in 149 g of ammonium phosphate is 31 g(atomic mass of P).
Now, we could use the proportions to find out the mass percentage of P in the sample.
31 g P is present in 149 g of ammonium phosphate, how many grams of P would be present in 60.9 g of ammonium phosphate. Let's set the proportions as:
[tex]\frac{31}{149}=\frac{x}{60.9}[/tex]
[tex]x=\frac{31(60.9)}{149}[/tex]
[tex]x=12.7[/tex]
This 12.7 g of phosphorous is present in 100 g of the sample means there is 12.7% phosphorous in the sample.

The requirements of atoms to be able to participate in hydrogen bonding with a hydrogen atom include
all of the following except
A. atoms must have one lone pair of electrons.
B. atoms must be electronegative.
C. atoms must be small.
D. atoms must not be able to closely approach the hydrogen.
Answer: C. atoms must be small.
Explanation: Hydrogen bond is the result of the electrostatic forces of attraction between the hydrogen and the electonegative atom. It is a type of dipole dipole interaction which is not so much of a covalent bond.
The options A, B and D satisfies the definition of the hydrogen bonding but the option C seems to be irrelevant as hydrogen bonding does not deal with the size of the atom.
Thus for the hydrogen bonding , the other atom must be electronegative, and atoms must have atleast one lone pair of electrons and atoms must not be able to closely approach the hydrogen.
How do you turn a proportionality between variables into an equation?
Answer. By adding the proportionality constant .
Explanation:
suppose 'x' a is directly proportional to the 'y' , where x and y are variables:
x ∝ y
with an input of constant value 'K' proportionality relation gets converted into an equation:
x = K y
For example : Gravitational force is directly proportional to the product of two masses and inversely proportional to the square of the distance between the two masses.
F ∝ [tex]\frac {m_1m_2}{r^{2}}[/tex]
To convert this proportionality relation constant 'G' was introduced known as gravitational constant whose value remains constant under every conditions.
[tex]F=\frac {G\times m_1m_2}{r^{2}}[/tex]
[tex]G=6.67408\times 10^{-11}m^3Kg^{-1}s^{-2}[/tex]

What is the mass of a sample of aluminum that absorbs 596 J of heat when the temperature is raised from 30.0°C to 100.1°C? Specific heat of aluminum = 0.900 J/g oC
Answer is: the mass of a sample of aluminum is 9.45 grams.
ΔT = 100.1°C - 30.0°C.
ΔT = 70.1°C.; change in temperature of a sample of aluminium.
Cp(Al) = 0.900 J/g·°C; specific heat capacity for aluminium.
Q = 596 J; heat absorbed.
Q = m(Al) · ΔT · Cp(Al).
m(Al) = Q ÷ (ΔT · Cp(Al)).
m(Al) = 596 J ÷ (70.1°C · 0.900 J/g·°C).
m(Al) = 9.45 g; mass of aluminium sample.
Which one of the following mixtures is classified as a suspension
Final answer:
A suspension is a heterogeneous mixture where the dispersed particles are large enough to settle upon standing. Mud in water is an example of a suspension because it has large particles that are visible, the mixture is cloudy, and particles settle when undisturbed.
Explanation:
To identify which mixture is classified as a suspension, it's essential to understand the particle sizes involved in different mixtures. A suspension contains particles with diameters around 1 µm (1000 nm) that are dispersed throughout another phase. Examples of suspensions include muddy water and paint. In contrast, colloids involve much smaller particles (2 to about 500 nm in diameter) that do not settle on standing, such as milk or fog.
Considering the information provided, a suspension is a heterogeneous mixture where the dispersed particles are large enough to settle out upon standing. These particles can often be separated from the dispersing medium by filtration. In contrast, a solution has much smaller particles that do not settle and cannot be filtered out.
From the examples provided, mud in water fits the definition of a suspension. The particles are of appropriate size, it's heterogeneous, the mixture is cloudy due to the particles, and it will allow for settling over time if left undisturbed.
Wheen 56j of heat are added to 11g of liquid, its temperature rises from 10.4 degrees celsius to 12 degrees celsius. What is the heat capacity of the liquid
[tex]c = 3.2 \; \text{J} \cdot \text{kg}^{-1} \cdot \text{K}^{-1}[/tex]
Energy change [tex]Q = 56 \; \text{J}[/tex]Mass being heated [tex]m = 11 \; \text{g}[/tex]Temperature change [tex]\Delta T = 12 - 10.4 = 1.6\;^{\text{o}}\text{C}[/tex] which is the same as [tex]1.6 \;\text{K}[/tex].Heat capacity measures the energy required to raise the temperature of a unit mass of a substance by a unit degree. Therefore
[tex]c = Q / (m \cdot \Delta T) = 56/(11 \times (12 - 10.4)) = 3.2 \; \text{J} \cdot \text{kg}^{-1} \cdot \text{K}^{-1}[/tex]
Answer : The heat capacity of liquid will be, [tex]3.18J/g^oC[/tex]
Explanation :
Formula used :
[tex]Q=m\times c\times \Delta T\\\\Q=m\times c\times (T_2-T_1)[/tex]
where,
Q = heat absorb = 56 J
m = mass of liquid = 11 g
c = specific heat of liquid = ?
[tex]\Delta T[/tex] = change in temperature
[tex]T_1[/tex] = initial temperature = [tex]10.4^oC[/tex]
[tex]T_2[/tex] = final temperature = [tex]12^oC[/tex]
Now put all the given value in the above formula, we get:
[tex]56J=11g\times c\times (12-10.4)^oC[/tex]
[tex]c=3.18J/g^oC[/tex]
Therefore, the heat capacity of liquid will be, [tex]3.18J/g^oC[/tex]

12. What volume of carbon dioxide contains the same number of molecules as 20.0 mL of oxygen at the same conditions?
What is the molarity of 820 ml of kl solution that contains 36.52 g of kl
The formula is molarity (M) = moles / liters
molarity (M) = ?
1/ mass = 36.52 g of KCl (you need to find the mole)
mole = mass / Molar mass
Molar mass of KCl:
K = 39.10 g/mol
Cl = 35.45 g/mol
Add K and Cl together: 39.10 + 35.45 = 74.55 g/mol
mole = 36.52 g of KCl / 74.55 g/mol
mole = 0.489 mol of KCl
2/ Volume = 820 mL ( you need to convert to L)
820 / 1000 = 0.82 L
=> M = mol / L
M = 0.489 mol / 0.82 L
M = 0.59 mol/L
Hope this help!
Answer: 0.27 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{36.52g}{166g/mol}=0.22moles[/tex]
[tex]V_s[/tex] =volume of solution in ml
Molarity =[tex]\frac{0.22\times 1000}{820ml}=0.27M[/tex]
The molarity of the solution is 0.27 M.
