Answer:
are you to measures how much solute dissolved with the water or trying to measure how much more water you need the solute to dissolve in ?
The solute is a component of the solution that is added to a solvent to make a solution. when equilibrium is attained then the solution will be saturated.
What is a saturated solution?A saturated solution is a solution that contains the maximum amount of dissolved solute particles in it and cannot further dissolve solutes added additionally.
When the solute is added and does not get dissolved then the equilibrium between dissolved and undissolved is reached and the solution becomes saturated.

if 146.5 g of chromium(lll) chlorate decomposes, what mass of oxygen can be produced?
Answer:
The Equation for this reaction is as follow,
2 Cr(ClO₃)₃ → 2 CrCl₃ + 9 O₂
According to eq,
604.68 g (2mole) of Cr(ClO₃)₃ produces = 288 g (9 moles) of O₂
So,
146.5 g of Cr(ClO₃)₃ will produce = X g of O₂
Solving for X,
X = (146.5 g × 288 g) ÷ 604.68 g
X = 69.77 g of O₂

Answer these questions based on 234. 04360 as the atomic mass of thorium-234. The masses for the subatomic particles are given. Round the mass defect to the 5th decimal place. Mass of a proton: 1. 00728 amu mass of a neutron: 1. 00866 amu How many protons does Thorium have? How many neutrons does Thorium-234 have? Calculate the mass defect for the isotope thorium-234 = amu.
The mass defect for the isotope thorium-234 if given mass is 234.04360 amu is 1.85864 amu.
How do we calculate atomic mass?Atomic mass (A) of any atom will be calculated as:
A = mass of protons + mass of neutrons
In the Thorium-234:
Number of protons = 90
Number of neutrons = 144
Mass of one proton = 1.00728 amu
Mass of one neutron = 1.00866 amu
Mass of thorium-234 = 90(1.00728) + 144(1.00866)
Mass of thorium-234 = 90.6552 + 145.24704 = 235.90224 amu
Given mass of thorium-234 = 234.04360 amu
Mass defect = 235.90224 - 234.04360 = 1.85864 amu
Hence required value is 1.85864 amu.

carbon atoms have a mass of 24 grams. What is the mass of the hydrogen atoms?
Explain your reasoning.
The mass of hydrogen atoms in the compound would be 2 grams.
Stoichiometric calculationThe carbon atoms in the compound have a mass of 24 grams.
One carbon atom has a mass of 12 grams. Thus, there are two (12 x 2 = 24) carbon atoms in the compound.
This means that there are also two hydrogen atoms in the compound. One hydrogen atom weighs 1 gram. Hence, the mass of the hydrogen atoms in the compound will be 2 grams.

Does electronegativity affect replacement reactions
Elecetronegativity will affect the replacement reactions as it attracts the bonded electrons towards itself.
What is replacement reaction?Replacement reactions are those reactions in which replacement of any one element from any compound is done by any other element.
Electronegativity is the attracting power of any element to hold the bonded electron towards itself so that they will bear a partial negative charge on itself. If in any reaction replacement of anion is required and any compound have more electronegative element which bounded the bonded electron strictly and will not allow the formation of anion then it affects the activity of the reaction.

If a reaction is second-order with respect to a particular reactant, when the concentration of that reactant is increased by a factor of 4, the reaction rate will _____
Answer:
A reaction is second order with respect to a reactant.
Rate =k[A]
2
(i) If the concentration of the reactant is doubled, the rate of reaction becomes 4 times .
(ii) If the concentration of the reactant is reduced to half, the rate of reaction becomes one fourth.
Explanation:
If a reaction is second-order with respect to a particular reactant, when the concentration of that reactant is increased by a factor of 4, the reaction rate will increased by factor 16.
How do we calculate the rate of second order reaction?Rate of the second order reaction will depends on the concentrations of one second-order reactant or two first-order reactants as:
Rate(1) = k[A]²
If the concentration of reactant becomes 4 times the initial concentration then rate will be:
Rate = k[4A]²
Rate(2) = 16k[A]²
Rate(2) = 16Rate(1)
Hence rate will increased by 16 times.
