Answer:
C2H5
Explanation:
you first find the number of moles of both substances then divide by the lowest number in this case carbon was 1 and hydrogen was 2,515... then you multiply by a whole number which was 2 then it was now C2H5
1) The time depends on what the lab wanted you to do. It will tell you in the procedure when you are supposed to considered a reaction to be complete and you just measure the time for that to happen.
2) Most text books say that increasing the concentration of one or more reactants will increase the rate of the reaction. To prove this with your data you need to show that when you increased the concentration of one of the reactants, the reaction rate did increase. The results of this experiment are not enough to make a general statement since the experiment was not on a large enough scale to diffidently prove anything. (you could have been testing the one exception or had a error in one of your trials)
I hope this helps. Let me know in the comments if anything is unclear.
(The concentration of one or more of the reactants will increase the rate of the reaction. This is explained through the fact that all reactions require collisions that have certain orientations and a minimum energy level. By increasing the concentration of one or more reactants, you increase the number of collisions which increases the rate since requires collisions in order to occur.) <span />

Answer: option B, Dipole-Dipole forces
Explanation:
By VESPER theory, shape of H2S is bent and Central atom Sulfur has two lone pair of electrons. Because of asymmetrical shape ,H2S is polar molecule.
Due to polar nature it has strong dipole-dipole intermolecular forces
The atomic mass of a carbon atom is 12. 011 u. convert this mass to units of kilograms and MeV are 12.011 × 10^(-3) kg and 11182.24MeV.
<h2>What is atomic mass? </h2>
The mass of an atom of a chemical element which is expressed in atomic mass units is termed as atomic mass.
Given,
the atomic mass of carbon atom = 12.011u
As we know that
1u = 1g
12.011u = 12.011g
So. the atomic mass of carbon atom in g = 12.011g
<h3>Atomic mass in Kg</h3>
1 Kg = 1000g
1g = 10^(-3)Kg
12.011g = 12.011 × 10^(-3) kg.
<h3>Atomic mass in MeV</h3>
1u = 931MeV
12.011u = 12.011 × 931MeV
= 11182.24MeV
Thus, the value of atomic mass of carbon atom in Kg and MeV are 12.011 × 10^(-3) kg and 11182.24MeV.
