Why does the freezing of water, exothermic process,become spontaneous at temperatures below 0° C even though the entropy of liquid water decreases during the phase change?
Answer:
Because the melting of ice as a spontaneous process (or reaction).
Explanation:
Here is an example:
Take a ice on a plate and leave it for half an hour (conditions). After half an hour, we notice water instead of ice.
This process took place without any intervention from your side. Heat absorbed by the ice from surrounding is due to set of conditions not due to your intervention.
So, we can consider melting of ice as a spontaneous process (or reaction).
if I have a +2 oxidation number do I give up or accept electrons?
Answer:
I will give up the electrons
Explanation:
Consider the following rules:
1. An atom loses electrons if its oxidation number is positive.
2. An atom gains electrons if its oxidation number is negative.
3. An atom neither gains nor loses electrons if its atomic number is zero.
As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.
Two people are playing tug of war. One person pulls to the right with 32 N of force. The other person pulls to the left with 37 N of force. How strong is the net force and in which direction?
Answer:
The net force is 5 N and to the left.
Explanation:
37 N - 32 N = 5 N and since there is a stronger pull from the rope moves towards the left so the direction of motion is left.

You have returned home from practice and there is a note on the fridge that says:
“There’s pizza in the fridge, reheat in the microwave if you’re hungry.”
You put the pizza in the microwave and pour yourself a glass of lemonade while you wait. The microwave beeps, and you pull the hot pizza out and set it on the counter. As you set the pizza down, you accidently knock your lemonade over. It takes you a few minutes to clean up the mess, so when you finally come back to the pizza, it is cool.
Draw a molecular model of the pizza as it cools. Include a written explanation.
Be sure to include in your model:
An arrow showing overall (macroscopic) energy movement
Air molecules with motion arrows
Pizza molecules with motion arrows
Collisions between the two molecule types

supports that a chemical change has occurred.
A gas is produced.
B)The color changed.
c) Bubbling occurred.
D) The baking soda dissolved.
E) There is a change in the composition of the reactants.
ANOTHER HELP OVER HEREEEEEE PLSSSSSSS
The declaration made in the image's results indicates that a chemical shift has taken place. There occurs the creation of gas.
What occurred when you put vinegar in the water?This occurs as a result of vinegar's composition of acetic acid and water. Acetic acid and water molecules create robust connections. These bonds cause the molecules inside the solution to move more slowly than those in pure water, hastening the freezing of the solution.
Briefing:A cup of vinegar and a cup of warm water are the basic components of the vinegar cleaning solution. Grease as well as hard water stains are easier to remove with warm water. It may be best to combine the vinegar and distilled water rather than tap water when filling a spray container that will be used often.
To create a chemical reaction, what can you combine with vinegar?A chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) results in the production of salt (sodium acetate), water, and carbon dioxide gas.

b) Why is aluminium extracted using electrolysis and not carbon?
Answer:
Aluminum is more reactive than carbon so it must be extracted from its compounds using electrolysis.
Explanation:
Even though aluminum is more abundant than iron in the Earth's crust, aluminum is more expensive than iron. This is mainly because of the large amounts of electrical energy used in the extraction process.
An equimolar mixture of X (g) and Y (g) is placed inside a rigid container at constant temperature. The particle diagram above represents the changes that occur over time. Based on the particle
diagram, which of the following best predicts whether or not the system has reached equilibrium by 300 s?
a. It is not possible to determine that the system has reached equilibrium by 300 s because the stoichiometry of the reaction is not known.
b. it is not possible to determine that the system has reached equilibrium by 300 s because the amounts of X, Y, and XY have continued to change
c. The system has reached equilibrium by 300 s because the rate of formation of XY is constant
d. The system has reached equilibrium by 300 s because the rates of consumption of X and Y are equal
Answer:
B
Explanation:
t= 300s has more XY than t=200s, which means that it continues to change
*i think
The system has been predicted to be not possible to reach equilibrium as changing X and Y concentration. Thus, option B is correct.
Equilibrium has been described as the condition in the reaction mixture, when the concentration of the product and the reactant are equal.
The given reaction has been represented as:
[tex]\rm X+Y\rightarrow\;XY[/tex]
Reaction mixture at 300 sThe given reaction has been represented as, with the increase in time, there has been the consumption of the reactant and the formation of product.
The concentration has been continuously changing with time. Thus, the determination of the equilibrium has been difficult with changing X and Y concentration.
Thus, option B is correct.

Difficult Question but I would say no
Explanation:
I say no because the whole premise of a chemical reaction is the reaction to new bonds and bond losses happening due to the introduction of a new substance. If the substance hasn't changed at all, it wouldn't be a chemical reaction because their would be nothing reacting.
What is the primary difference between two different isotopes?
Answer:
Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.

Explanation:
A bottle contains 158.1 grams of lead (II) sulfate (PbSO4), used for car batteries. How many moles does it contain?
Number of moles =0.52 moles
The number of moles is defined as the ratio between given mass and molar mass.
Given:
Mass of PbSO₄ = 158.1 grams
To find:
Number of moles=?
Molar mass of PbSO₄ = 303.26 g/mol
[tex]\text{Number of moles}= \frac{\text{Given mass}}{\text{Molar mass}}\\\\\text{Number of moles}= \frac{158.1}{303.26}\\\\ \text{Number of moles}= 0.52\text{ moles}[/tex]
Thus, the number of moles it contain will be 0.52.
