Aleonysh [2.5K]

Answer:

Option A = atomic masses

Explanation:

In compound molecular mass is the sum of the individual atomic masses of the atoms.

For example

Compound NaCl.

atomic weight of sodium = 23 g/mol

atomic weight of chlorine = 35.5 g/mol

Molar mass of NaCl = 23+ 35.5 = 58.5 g/mol

Every atom consist of nucleus or a positive center. The protons and neutrons are present with in the nucleus while electrons are present out side the nucleus. All these three subatomic particles construct an atom. The number of protons or number of electrons are the atomic number of an atom while the number of protons and number of neutrons are the mass number of an atom. A neutral atom have equal number of protons and electrons. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.

Cyclopropane is converted to propene in a first–order process with a rate constant of 5.4 × 10–2 hour–1 . The initial concentrat
Hitman42 [59]

Answer:

The concentration of cyclopropane after 22.0 hour is 0.0457 M.

Explanation:

Conversion of cyclopropane into propene follows first order kinetics.

The integrated rate of first order kinetic is given by :

[A]=[A_o]\times e^{-kt}

[A_o] = Initial concentration of reactant

[A] = final concentration of reactant after time t

k = rate constant of the reaction

We have :

Rate constant of the reaction = k = 5.4\times 10^{-2} hour^{-1}

[A_o]=0.150 M

t = 22.0 hour

[A] =?

[A]=0.150 M\times e^{-5.4\times 10^{-2} hour^{-1}\times 22.hour}

[A]=0.0457 M

The concentration of cyclopropane after 22.0 hour is 0.0457 M.

PLEASE HELP, EASY QUESTION!!!!  Which of the following best describes the freezing of water?
VLD [36.1K]
I think the correct answer would be negative change in enthalpy, low temperature and negative entropy. Freezing of water is an exothermic process which means heat is released to the surroundings so negative enthalpy. And this is seen in the change to a lower temperature. Entropy is negative which signifies that there is more order as water freezes.
