Answer: Option (a) is the correct answer.

Explanation:

A chemical reaction in which there will be absorption of heat energy by the reactant molecules is known as endothermic reaction.

For example, A + B + Heat \rightarrow C + D is an endothermic reaction.

On the other hand, a chemical reaction in which there will be release of heat energy is known as an exothermic reaction.

For example, A + B \rightarrow C + D + Heat is an exothermic reaction.

Therefore, we can conclude that the given thermochemical equation A + B + Heat \rightarrow C + D shows endothermic type of reaction.

The reaction, as what is depicted in the thermonuclear equation is one of the best example of an endothermic reaction. In addition, the endothermic process revolves around the idea that the system can also absorb the energy from its surroundings, in contrast to the idea of releasing its energy to its environment.

"A crosslinked copolymer consists of 57 wt% ethylene (C2H4) repeat units and 43 wt% propylene (C3H6) repeat units. Determine the
ch4aika [34]

Explanation:

Percentage ethylene by weight = 57%

Percentage propylene by weight = 43%

Suppose in 100 grams of polymer:

Mass of ethylene = 57 g

Mass of propylene = 43 g

Moles of ethylene = \frac{57 g}{28 g/mol}=2.036 mol

Moles of propylene = \frac{43g}{42g/mol}=1.024 mol

1 mole = N_A =6.022\times 10^{23} molecules/ atoms

Units of ethylene = 2.036 mol\times N_A

Units of propylene = 1.024 mol\times N_A

a) Fraction of ethylene units:

=\frac{2.036 mol\times N_A}{2.306 mol\times N_A+1.024 mol\times N_A}=\frac{509}{765}

b ) Fraction of propylene units:

=\frac{1.024mol\times N_A}{2.306 mol\times N_A+1.024 mol\times N_A}=\frac{256}{765}

1. Express in conventional notation (no exponents) in the space provided within the
mina [271]

Answer:

a) 320: two significant figures.

b) 2,366: four significant figures.

c) 73.0: three significant figures.

d. 532.5: four significant figures.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to write each number by knowing we move the decimal places to the right as much as the exponent is, and also, we count every figure, even zeros, because they are to the right of the first nonzero digit:

a) 320: two significant figures because the rightmost zero is not preceded o followed by a decimal place.

b) 2,366: four significant figures.

c) 73.0: three significant figures, because the zero is followed by the decimal place.

d. 532.5: four significant figures.

Regards!
