Use the following balanced reaction to solve:
Naily [24]

Answer:  60.7 g of PH_3 will be formed.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given volume}}{\text{Molar volume}}    

\text{Moles of} H_2=\frac{60L}{22.4L}=2.68moles

The balanced chemical reaction is

P_4(s)+6H_2(g)\rightarrow 4PH_3(g)

H_2 is the limiting reagent as it limits the formation of product and P_4 is the excess reagent.

According to stoichiometry :

6 moles of H_2 produce = 4 moles of PH_3

Thus 2.68 moles of H_2 will produce=\frac{4}{6}\times 2.68=1.79moles  of PH_3

Mass of PH_3=moles\times {\text {Molar mass}}=1.79moles\times 33.9g/mol=60.7g

Thus 60.7 g of PH_3 will be formed by reactiong 60 L of hydrogen gas with an excess of P_4

7. Jasmine wants to prevent getting burned by accidently touching a hot metal pipe, What would be the worst
tatyana61 [14]

Answer:

A) Glass

Explanation:

Glass is a conductor, so it allows heat to go through it (Ex. Touching a pie pan that came right out of the oven)

Rubber is an insulator, so heat has a hard time passing through (Ex. Using a rubber grip on a cast iron pan.

Cloth is also an insulator, so heat has a hard time passing through (Ex. Using a pot holder to prevent the counter from getting scarred)

Wood is also an insulator, so heat has a hard time passing through (Ex. Bedding for a rabbit hutch)

Hope this helps!!
