The statement, "In a chemical reaction, matter is neither created nor destroyed" is called a the Law of Multiple Proportions. b
Anettt [7]

Answer:

D

Explanation:

The statement in the question above gives the statement of the law of conservation of matter. The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.

This particular law is talking about the indestructible nature of matter. Whatever form of matter we have presently was as a result of the fact that it was converted to from one initial form. It is this fundamental law that guides the operation of a wide number of scientific operations. Things like reaction between substances to form entirely or partially new substances are guided by these fundamental laws of nature

Which of the following elements has the highest electronegativity?
Ira Lisetskai [31]
One of them oxygen or chlorine, the reason is that from the left to the right the electronegativity increases as well from the bottom to the top it increases as well :)) so the chlorine and oxygen is near each other so i cant decide cuz im not sure ☹️☹️

if I add water to 170 mL of a 0.40 M KOH solution until the final volume is 375 mL, what will the molarity M of the diluted solu
nasty-shy [4]

4.7 M It may be wrong, but I hope it helps!

Explanation:

When you're diluting a solution, you're essentially keeping the number of moles of solute constant while changing the total volume of the solution.

Now, let's assume that you don't know the equation for dilution calculations.

In this case, you can use the molarity and volume of the concentrated solution to determine how many moles of hydrochloric acid you start with.

=

You then add water to get the total volume of the solution from  

190 mL

to

.

The number of moles of hydrochloric acid remains unchanged, which means that the molarity of the diluted solution will be

in carbon tetrachloride proceeds as follows: 2N2O5→4NO2+O2. The rate law is first order in N2O5. At 64 ∘C the rate constant is 4
Nesterboy [21]

Answer:

Part A

rate= 4.82*10^{-3}s^{-1} * [N2O5]

Part B

rate= 1.35*10^{-4}Ms^{-1}

Explanation:

Part A

<em>The rate law is the equation that relates the rate of the reaction, the kinetic constant and the concentration of the reactant or reactants.</em>

For the given chemical reaction we can write a general expression for the rate law as follows:

rate= k * [N2O5]^{x}

where k is the rate constant and x is the order of the reaction with respect of N2O5 concentration. Particularly, <em>a first order reaction kinetics indicate that the rate of the reaction is directly proportional to the concentration of only one reactant</em>. Then x must be 1.

Replacing the value of the rate constant given in the text we can arrive to the following expression for the rate law:

rate= 4.82*10^{-3}s^{-1} * [N2O5]

Part B

Replacing the value of the concentration of N2O5 given, we can get the rate of reaction:

rate= 4.82*10^{-3}s^{-1} *2.80*10^{-2}M

rate= 1.35*10^{-4}Ms^{-1}
