Answer:

The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.

A closed system consists of 0.3 kmol of octane occupying a volume of 5 m3 . Determine

Alenkinab [10]

Answer:

(a). The weight of the system is 336.32 N.

(b). The molar volume is 16.6 m³/k mol.

The mass based volume is 0.145 m³/kg.

Explanation:

Given that,

Weight of octane = 0.3 kmol

Volume = 5 m³

(a). Molecular mass of octane

$M=114.28\ g/mol$

We need to calculate the mass of octane

Mass of 0.3 k mol of octane is

$M=114.28\times0.3\times1000$

$M=34.284\ kg$

We need to calculate the weight of the system

Using formula of weight

$W=mg$

Put the value into the formula

$W=34.284\times9.81$

$W=336.32\ N$

(b). We need to calculate the molar volume

Using formula of molar volume

$\text{molar volume}=\dfrac{volume}{volume of moles}$

Put the value into the formula

$\text{molar volume}=\dfrac{5}{0.3}$

$\text{molar volume}=16.6\ m^3/k mol$

We need to calculate the mass based volume

Using formula of mass based volume

$\text{mass based volume}=\dfrac{volume}{mass}$

Put the value into the formula

$\text{mass based volume}=\dfrac{5}{34.284}$

$\text{mass based volume}=0.145\ m^3/kg$

Hence, (a). The weight of the system is 336.32 N.

(b). The molar volume is 16.6 m³/k mol.

The mass based volume is 0.145 m³/kg.

To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newt

Firdavs [7]

Answer: A.E.

Explanation: To understand the distinction between mass and weight and to be able to calculate the weight of an object from its mass and Newton's law of gravitation. The concepts of mass and weight are often confused. In fact, in everyday conversations, the word "weight" often replaces "mass," as in "My weight is seventy-five kilograms"

Nitrogen gas (N2) and hydrogen gas (H2) combine to form ammonia (NH3). Which equation correctly represents this reaction?

sweet [91]

Answer:

The correctly equation is D) N2+ 3H2 → 2NH3

Explanation:

Both nitrogen and hydrogen are presented in bimolecular form (N2 and H2), on one side and on the other side of the equation we have 2 Nitrogens and 6 Hydrogens (it is balanced)
