<h3><u>Answer</u>;</h3>

= 1.44 L

<h3><u>Explanation</u>;</h3>

Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.

Mathematically;

<em>P α 1/V</em>

<em>PV =constant </em>

<em>Thus, P1V1 = P2V2 </em>

<em>P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm</em>

<em>V2 = P1V1/P2</em>

<em>     = (1× 3.6)/2.5 </em>

<em>     = </em><u><em>1.44 L</em></u>

A flexible container at an initial volume of 6.13 L contains 6.51 mol of gas. More gas is then added to the container until it r
aivan3 [116]

Answer:

the final mole of the flexible container = 12.92 moles

Explanation:

Given that :

initial volume of a flexible container = 6.13 L

initial mole of a flexible container = 6.51 mol

final volume of a flexible container = 18.3 L

final mole of a flexible container = ???

Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Therefore,

n= \dfrac{V_2*n_1}{V_1}

n= \dfrac{18.3*6.51}{6.13}

n = 19.43

n=n_1+n_2

19.43 = 6.51 + n₂

n₂ = 19.43 - 6.51

n₂ = 12.92 moles

Thus; the final mole of the flexible container = 12.92 moles

What might be your reference point other than yourself if you determine that the dog is not moving?
Anettt [7]

Complete statement:

Suppose your in the car with the dog. What might be your reference point other than yourself if you determine the the dog is not moving.

Answer:

The car

Explanation:

A reference point is a place or object used for comparison to determine whether something is in motion. If the dog is in the car with me, and the reference point would be the car other than me. For a car, the dog is also not in the motion.

A sample of sodium reacts completely with 0.213 kgkg of chlorine, forming 351 gg of sodium chloride. What mass of sodium reacted
lapo4ka [179]

Answer:

The mass of sodium reacted is 138 grams

Explanation:

Firstly, the chemical reaction should be represented with a balance chemical equation. The chemical equation can be written as follows.

Na = sodium

Cl2 = chlorine gas

Na + Cl2 → NaCl

The balanced equation is

2Na(s) + Cl2(g) → 2NaCl(aq)

Atomic mass of sodium = 23 grams per mol

Atomic mass of chlorine = 35.5 grams per mol

From the chemical equation the molar mass are as follows

Sodium = 2 × 23 = 46 grams

Chlorine = 35.5 × 2 = 71 grams

Sodium chloride =  2 × 23 + 2 × 35.5 = 117 grams

if 46 grams sodium reacted to produce 117 grams of sodium chloride

? grams of sodium react to produce 351 grams sodium chloride

grams of sodium reacted = (351 × 46)/117

grams of sodium reacted = 16146/117

grams of sodium reacted = 138  grams
