According to the following reaction, how many grams of carbon tetrachloride will be formed upon the complete reaction of 27.7 gr

Black_prince [1.1K]

Answer: 15.0 g of $CCl_4$ will be formed upon the complete reaction of 27.7 grams of chlorine gas with excess carbon disulfide

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Cl_2=\frac{27.7g}{71g/mol}=0.390moles$

The balanced chemical reaction is:

$CS_2(g)+4Cl_2(g)\rightarrow CCl_4(l)+2SCl_2(s)$

$Cl_2$ is the limiting reagent as it limits the formation of product and $CS_2$ is the excess reagent.

According to stoichiometry :

4 moles of $Cl_2$ give= 1 mole of $CCl_4$

Thus 0.390 moles of will give = $\frac{1}{4}\times 0.390=0.0975moles$ of $CCl_4$

Mass of $CCl_4=moles\times {\text {Molar mass}}=0.0975\times 154=15.0g$

Thus 15.0 g of $CCl_4$ will be formed upon the complete reaction of 27.7 grams of chlorine gas with excess carbon disulfide

The joule is an SI unit of energy that is equal to 1 kg•m2/s2. The erg is a different unit of energy that is equal to 1 g•cm2/s2

vredina [299]

Answer:

The answer to your question is: 1 J = 10, 000, 000 ergs

Explanation:

(1 kgm²/s²)(1000 g/ 1 kg) = 1000 gm²/s²

(1000 gm²/s²)(100 cm/1 m) = 1 00 000 gmcm/s²

1 00 000 gmcm/s² (100 cm / 1m) = 10 000 000 gcm²/s²

= 10 000 000 ergs

Convection currents slowly move tectonic plates across Earth<br><br> True or False?

n200080 [17]

Answer: True

Explanation: As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

How many moles of \ce{AgCl}AgClA, g, C, l will be produced from 60.0 \text{ g}60.0 g60, point, 0, start text, space, g, end text

lozanna [386]

Answer:

For 0.353 moles AgNO3, we'll have 0.353 moles AgCl

Explanation:

How many moles of AgCl will be produced from 60.0g AgNO3 assuming NaCl is available in excess.

Step 1: Data given

Mass of AgNO3 = 60.0 grams

Molar mass AgNO3 = 169.87 g/mol

NaCl is in excess, so AgNO3 is the limiting reactant

Step 2: The balanced equation

AgNO3 + NaCl → AgCl + NaNO3

Step 3: Calculate moles AgNO3

Moles AgNO3 = mass AgNO3 / molar mass AgNO3

Moles AgNO3 = 60.0 grams / 169.87 g/mol

Moles AgNO3 = 0.353 moles

Step 4: Calculate moles AgCl

For 1 mol AgNO3 we need 1 mol NaCl to produce 1 mol AgCl and 1 mol NaNO3

For 0.353 moles AgNO3, we'll have 0.353 moles AgCl
