tetraphosphorous hexaoxide is formed by the reaction of phosphorous (p4) with oxygen gas. if the reaction of 75.3 g of p4 with 3
True [87]

the Percentage yield for the reaction = 48.8%

What is Percentage yield ?

The % ratio of the theoretical yield to the actual yield is known as the percent yield. It is calculated as the theoretical yield multiplied by 100% divided by the experimental yield. The percent yield is 100% if the theoretical and actual yields are equal. Because the real yield is frequently lower than the theoretical value, percent yield is typically lower than 100%. This may be due to incomplete or conflicting reactions or sample loss during recovery. If the percent yield is more than 100%, more sample than expected was retrieved from the reaction.

4 P + 3 O2 = P4O6

moles P = 75.3 g / 30.9738 g/mol= 2.43

moles O2 required = 2.43 x 3 / 4=1.82

actual moles O2 = 38.7 g /32 g/mol=1.21 so O2 is the limiting reactant

theoretical moles P4O6 = 1.21 / 3=0.403

theoretical mass P4O6 = 0.403 mol x 219.895 g/mol=88.6 g

% yield = 43.3 x 100/ 88.6 = 48.8 %

the Percentage yield for the reaction = 48.8%

How many grams of hydrogen must react if the reaction needs to produce 31.75 grams of nh3
leva [86]
X= (3*2)(31.75)/(2*17)3*31.75/17
=5.603g H2

Answer: 5.603g H2

It’s all quite simple actually considering the fact the M(NH3) = 14 + 1*3 = 17g/mol
And M(H2) = 2*1 2g/mol

So 3H2 + N2 >> 2NH3

Givin that Xg is 31.75g

The iron with which they make the houses or bridges is the same as our blood?
Leviafan [203]

Explanation:

yes, they are the same.

"Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles."

Fun fact:

At 4 grams per person, you'd need at least 2,352 completely drained donors to make a iron longsword out of blood.
