Explanation:

As it is given that two gases A and B are mixed together and kept in a container with constant volume.

Also, kinetic energy of molecules is directly related to temperature as follows.

                K.E = \frac{3}{2}kT

As kinetic energy is directly proportional to temperature. So, when there will be decrease in temperature then kinetic energy of molecules will also decrease leading to less number of collisions between the molecules.

Hence, there will be decrease in rate of reaction.

Thus, we can conclude that when temperature is decreased at a constant volume then rate of reaction will also decrease.

The effect that the following changes have on the rate of the reaction between the gases A and B in a container when the temperature is decreased at a constant volume will decrease because the molecules of A and B are ineracting very slowly due to the decrease in temperature which results to the decrease in kinetic energy.

A sample of a compound is determined to have 1.17 g of carbon and 0.287 g of hydrogen. what is the correct representation of the
yarga [219]

CH3 is the empirical formula for the compound.

A sample of a compound is determined to have 1.17g of Carbon and 0.287 g of hydrogen.

The number of atom or moles in the compound is

1.17 g C X  1 mol of C / 12.011 g C = 0.097411 mol of C.

0.287 g H x 1 mol of  H / 1 g H = 0.28474 mol H.

This compound contains 0.097411 mol of carbon and 0.28474 mol of Hydrogen.

So we can represent the compound with the formula C0.974H0.284.

Subscripts in formulas can be made into whole numbers by multiplying the smaller subscript by the larger subscript.

we can divide 0.284 by 0.0974.

0.284 / 0.0974 = 3.

So here, Carbon is one and hydrogen is 3.

We can write the above formula as a CH3.

Hence the empirical formula for the sample compound is CH3.

If f is a reactive nonmetal, which other element or elements shown here do you expect to also be a reactive nonmetal?
vichka [17]
You did not include the list but F is fluorine. The first halogen.

So, you can expect that the other members of the same group (halogens, column 17 of the periodic table) exhibit similar chemical behavior (reactivity).

So, I am sure your list contains one or more of theses elements: Cl (chlorine), Br (bromine), and I (iodine).

All of them you can expect to also be reactive non metal.
