Molar mass of SnO_2:-

\\ \sf\longmapsto 118+2(16)=118+32=150g/mol

  • Given mass=80.8g

\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:mass}{Molar\:mass}

\\ \sf\longmapsto No\:of\;moles=\dfrac{80.8}{150}

\\ \sf\longmapsto No\:of\:moles=0.5mol

1 mol of SnO_2 produces 2mol of water

  • 0.5mol of SnO_2 will produce 0.5(2)=1mol of water

When a nonmetal gains electrons, it becomes this type of ion.
MrRa [10]

Answer:

When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. Most nonmetals become anions when they make ionic compounds. A neutral chlorine atom has seven electrons in its outermost shell.

A chemical manufacturer sells sulfuric acid in bulk at a price of $100 per unit. If the daily production cost in dollars for x u
sleet_krkn [62]

to solve the amount of sulfuric acid to maximize the profit we need to establish the profit

let S(x) = 100x the selling price

P = S(x) – C(x)

P = 100x – ( 100,000 + 50x + 0.0025x^2)

P = 50x – 100000 – 0.0025x^2

Getting the first derivative and equating it to 0

0 = 50 – 0.005x

X = 10000 units of sulfuric acid

But the capacity is only 7000 units

<span>So 7000 units should be manufactured</span>
