A chemist working for Udensi industries wants to create a new ink for tattoos and cosmetics. Determine the theoretical yield of
leva [86]

Answer:

35.36 g

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

8Fe + S₈ —> 8FeS

Next, we shall determine the mass of Fe that reacted and the mass of FeS produced from the balanced equation. This can be obtained as follow:

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 8 × 56 = 448 g

Molar mass of FeS = 56 + 32 = 88 g/mol

Mass of FeS from the balanced equation = 8 × 88 = 704 g

SUMMARY:

From the balanced equation above,

448 g of Fe reacted to produce 704 g of FeS.

Finally, we shall determine the theoretical yield of FeS as follow:

From the balanced equation above,

448 g of Fe reacted to produce 704 g of FeS.

Therefore, 22.5 g of Fe will react to produce = (22.5 × 704)/448 = 35.36 g of FeS.

Thus, the theoretical yield of FeS is 35.36 g

What would be the new volume if the pressure on 600 L is increased from 90.0 kPa to 150 kPa?
Liono4ka [1.6K]

Answer:

new Volume of gas=360L

Explanation:

Assume that given gas follow the ideality nature of gas

Assuming that temperature is constant;

P1 and V1 are the initial parameter of gas

and p2 and V2 are the parameter after increasing the pressure

according to boyle 's law pressure is inversly proportional to the volume at constant temperature.

P_1V_1=P_2V_2

given value of volume and gas

P1=90kPa

V1=600L

P2=150kPa

V2=?

After putting all values we get;

V2=360L

new Volume of gas=360L

A student is told to use 20.0 grams of sodium chloride to make an aqueous solution that has a concentration of 10.0 grams of sod
Butoxors [25]

Volume of the solution = 20.0 g NaCl * \frac{1 L solution}{10.0 g NaCl}

= 2 L solution x \frac{1000 mL}{1 L} =2000 mL

Volume of solute = 7.5 mL

Volume of water (solvent) = 2000 mL - 7.5 mL = 1992.5 mL water
