What mass of no2 can be produced from 3.56x10^22 molecules of oxygen? the equation with it is 4nh3+> 4no2+6h2o

Answers

Answer from: jr116641

Moles of O2 = 3.56x10^22/ 32 = 1.1125x 10^21

Maximum moles of NO2 producible = (1.1125x10^21/7) x 4 = 6.3571 x 10^20

Mass of 1 mole of NO2 = 14+32= 46

Therefore mass that can be produced= (6.3571x10^20) * 46 = 2.924x10^22 g

Answer from: Quest

$\frac{239}{94}pu+\frac{1}{0}n ====> \frac{y}{z}x+\frac{134}{54}xe+3\frac{1}{0}$

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137 subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54 subtract 54 from both sides.

40 = z

answer

$\frac{103}{40}x=\frac{103}{40}zr$

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
