Consider this second-order reaction: (A B C and rate = k[A]2). What will happen to the reaction rate if the concentration of A is doubled?

Answers

Answer:

The reaction rate will be multiplied by four.

Explanation:

The reaction rate is the measure of how fast a reaction is happening, and it can be calculated by how fast the reactants are disappearing, or how fast the products are being formed.

For a generic reaction:

A → B + C

The rate (r) is:

-r = k*[A]ⁿ

The minus signal refers to the disappearing of the reactant, k is the velocity constant of the reaction, and n is the reaction order. So, for a second-order reaction:

-r = k*[A]²

If the concentration of A is doubled: [A]' = 2[A]

-r' = k*(2[A])²

-r' = k*4*[A]

-r' = 4*k*[A]

-r' = 4*(-r)

It will increase by a factor of four.

A substance is tested in a lab. It is found to maintain a unique shape and is a good conductor of electricity. If it is made up of electrons, protons, and neutrons, what state of matter is this substance most likely to be?

Answers

Answer : Solid

Explanation :

When the substance was tested in the lab it was seen that it maintains a unique shape, which is the differentiating property of solids. Also, they are very good conductors of electricity. Solid contains electrons, protons and neutrons this is a common thing which is found in every state of matter. This all details confirms that it will be solid.

if its made up of electrons, protons, and neurons, the state of matter in this substance is most likely to be : Solid

we know that the substance
- a good conductor (and most of good conductors are metals and almost all the metals are solid)
- Could maintain a unique shape (gas technically does not have a shape and liquid's shape will be determined by the medium surrounding it)

Please help me with this question number 22

If I remember correctly 1 Cal (capital C) is equal to 1000 cal (lower case c) where Cal is used in nutrition since 1 cal is actually relatively small. If I am write about that, the answer should be 138Cal (nutritional calories) equals 138000cal. Therefore I think the answer is 138000cal.

I hope this helps. Let me know in the comments if anything is unclear.
