Answer:

If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots.

Carlos is making phosphorus trichloride using the equation below. He uses 15.5 g of phosphorus and collects 50.9 g of phosphorus

Oxana [17]

Answer : The mass of chlorine reacted with the phosphorus is, 53.25 grams.

Explanation :

First we have to calculate the moles of phosphorus.

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

$\text{Moles of phosphorus}=\frac{15.5g}{31g/mol}=0.5mol$

Now we have to calculate the moles of $Cl_2$

The balanced chemical reaction is:

$2P+3Cl_2\rightarrow 2PCl_3$

From the balanced chemical reaction, we conclude that

As, 2 moles of phosphorous react with 3 moles of $Cl_2$

So, 0.5 moles of phosphorous react with $\frac{3}{2}\times 0.5=0.75$ moles of $Cl_2$

Now we have to calculate the mass of $Cl_2$

$\text{Mass of }Cl_2=\text{Moles of }Cl_2\times \text{Molar mass of }Cl_2$

Molar mass of $Cl_2$ = 71 g/mol

$\text{Mass of }Cl_2=0.75mol\times 71g/mol=53.25g$

Therefore, the mass of chlorine reacted with the phosphorus is, 53.25 grams.
