I think you forgot to attach the diagram along with the question. I am answering the question based on my research and knowledge. "Count the number of protons" is the one among the following choices given in the question by which the <span>atomic number of nitrogen be determined. The correct option among all the options that are given in the question is the second option or option "B".</span>
It condenses when it passes below 212 degrees Celsius, or 100 degrees Fahrenheit
Answer:
158.5g Zn are produced
Explanation:
To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:
<em>Moles Al -Molar mass: 26.98g/mol</em>
43.6g Al* (1mol/26.98g) = 1.616 moles Al
<em>Moles Zn:</em>
1.616 moles Al * (3mol Zn / 2mol Al) =
2.424 moles Zn are produced
<em>Mass Zn -Molar mass: 65.38g/mol-</em>
2.424 moles Zn * (65.38g / mol) =
<h3>158.5g Zn are produced</h3>
