Answer:

pressure of gas are constant describe the relationship between moles and temprature

The statements correctly describes the relationship between volume and temperature is pressure of gas are constant.

The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure is the pressure. Pressure is expressed using a variety of units.

The volume of a gas is directly proportional to the number of moles of gas when both temperature and pressure are constant. The pressure of a gas is directly proportional to the number of moles of gas when both temperature and volume are constant.

In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.

Thus, If the pressure and temperature remain constant, the volume of a gas is directly proportional to the number of moles in the gas.

Answer:

the youngest crust of the ocean floor can be found near the seafloor

Answer:

0.0308 mol

Explanation:

In order to convert from grams of any given substance to moles, we need to use its molar mass:

Now we calculate the number of moles of KAI(SO₂)₂ contained in 5.98 g:

Answer:

Final Temp = 23.92°C

Explanation:

ΔH(total) = (m·c·ΔT)ice + (m·ΔH(f))melt'g + (m·c·ΔT)water

2182.5j = (5g)(2.092j/g·°C)(1°C) + (5g)(334.56j/g) + (5g)(4.184j/g·°C)(ΔT)

(2182.5 - 10.46 - 1672.8)j = 20.92j/°C·ΔT

ΔT = (2182.5 - 10.46 - 1672.8)j / 20.92j/°C = 23.92°C

Since the melting ice starts and ends at 0°C and is then warmed to 23.92°C then the temperature change is also the final temp of the water based upon given energy input values.

Answer:

218.98 grams

Explanation:

Given that,

No. of moles, n = 2.3

The molar mass of magnesium chloride is 95.211 g/mol.

We need to find the mass of 2.3 moles of magnesium chloride.

We know that,

No. of moles = given mass/molar mass

Let m be the given mass. So,

[tex]m=n\times M\\\\=2.3\times 95.211 \\\\=218.98\ g[/tex]

So, the required mass is equal to 218.98 grams.

Answer: 824.6 g of NaCl are produced from 500.0 g of chlorine.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]  [tex]\text{Moles of} Cl_2=\frac{500.00g}{71g/mol}=7.04moles[/tex]

[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]  

According to stoichiometry :

1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]

Thus 7.04 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{2}{1}\times 7.04=14.08moles[/tex]  of [tex]NaCl[/tex]

Mass of [tex]NaCl=moles\times {\text {Molar mass}}=14.08moles\times 58.5g/mol=824.26g[/tex]

Thus 824.6 g of NaCl are produced from 500.0 g of chlorine.

Blank 1: 1

Blank 2: 2

Blank 3: 1

Blank 4: 1

Explanation:

Assuming this is to balance the equation, write out the amount of each element you have on the reactants side and on the products side

Reactants                                                   Products

Ca 1                                                             Ca 1

C 2                                                              C 2

H 2                                                              H 4

O 1                                                               O 2

Comparing the two, we can see that hydrogen and oxygen have different amounts between reactants and products. Therefore, we need to multiply by some number to get the two equal. If we multiply the reactants by 2 we will get the correct amount in the products. So we put a 2 in front of the H₂O to signify this.

The balanced chemical reaction is

CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂
