Answer: 313.6
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require 3 moles of
Thus 2.8 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 2 moles of
Thus 2.8 moles of give = of
Mass of
Theoretical yield of liquid iron is 313.6 g
When we have Avogadro's number with four significant figures 6.022 x 10^23
and we have also this number 2.055 is also with four significant figures so,
the number of atoms = Avogadro's number / 2.055
= 6.022 x 10^23 / 2.055
= 2.930 x 10^23
and we can see that the result is number with four significant figures
471.45g of Mg3P2
Here’s the answer and work shown
The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body.
