Answer:D. Is the correct answer
Explanation:
Following are the calculation of the lead (Pb) atoms:
Balanced reaction:
[tex]\bold{3PbO+2NH_3\longrightarrow 3Pb+N2+3H2O}\\\\[/tex]
[tex]\bold{mol\ NH_3 \longrightarrow mol \ Pb \longrightarrow atoms \ Pb}[/tex]
Calculating the number of atoms in Pb that will be generated:
[tex]=5.38 \ mol \ NH_3 \times \frac{3\ mol\ Pb}{2 \ mol NH_3} \times \frac{6.022 \times 10^{23} \times pb}{1 \ mol \ pb}\\\\ = 4.86 \times 10^{24} \ atoms\ in \ Pb\\\\= 4.86 \times 10^{24} \ atoms \\[/tex]
Therefore, the answer is "Option D"

1) what is formed when hydrogen burns ? write the equation for the reaction .
2) why do you think that, when hydrogen burns, the flame Rises quickly ?
Answer:
formed by burns rises quickly hydorogen
[tex] H_2+\frac12O_2 \longrightarrow H_2O[/tex]
I don't think I need to name the product.
this reaction is very exothermic. so the gases and the flames are very hot, i.e. very lighter (hot air rises) than the normal air. so it rises quickly
Explain what a limiting reactant is and describe the process to determine the limiting reactant in the example listed below: Given 3.4 grams of x compound with a molar mass of 85 g and 4.2 grams of y compound with a molar mass of 48 g How much of compound xy can be generated 2x + y2 = 2xy
Answer:

Answer: The number of protons define what element we're dealing with.
calculate the percentage by mass of chlorine in Cobalt (II) chloride (cocl2)
Explanation:
Divide the mass of chlorine by the molar mass of cobalt chloride, then multiply by 100.
Molar Mass of Cobalt Chloride.
Mass of Chlorine in Cobalt Chloride.
Percent Composition of Chlorine.
