As a new mechanical engineer for Engines Inc., you have been assigned to design brass pistons to slide inside steel cylinders. T

he engines in which these pistons will be used will operate between 20.0 ∘C and 150.0 ∘C. Assume that the coefficients of expansion are constant over this temperature range.

A fusion reaction always creates which of the following?
ICE Princess25 [194]

A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.

A fusion reaction always creates a more massive atomic nucleus (option c).

When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.

This also indicates that the left over mass may have been released as energy.

Acetic acid (CH3COOH) is formed from its elements by the following reaction equation:
Alecsey [184]

Answer:

111 L

Explanation:

Calculation of moles of hydrogen gas:-

Mass of H_2 = 18.6 g

Molar mass of H_2 = 2.01588 g/mol

Moles=\frac{Mass}{Molar\ mass}=\frac{18.6}{2.01588}\ mol=9.23\ mol

According to the given reaction:-

2C+2H_2+O_2\rightarrow CH_3COOH

2 moles of hydrogen gas on reaction produces one mole of acetic acid gas.

So,

1 mole of hydrogen gas on reaction produces \frac{1}{2} mole of acetic acid gas.

Also,

9.23 mole of hydrogen gas on reaction produces \frac{1}{2}\times 9.23 mole of acetic acid gas.

Moles of acetic acid gas = 4.615 moles

Given that:

Temperature = 35 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T = (35 + 273.15) K = 308.15 K  

n = 4.615 moles

P = 1.05 atm

V = ?

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L atm/ K mol  

Applying the equation as:

1.05 atm × V = 4.615 moles ×0.0821 L atm/ K mol  × 308.15 K  

<u>⇒V = 111 L</u>
