6.75 moles of H₂

Explanation:

We have the following balanced chemical reaction:

Mg + 2 HCl → MgCl₂ + H₂

From the chemical reaction we deduce that if 1 mole of Mg is reating with 2 moles of HCl then 8.30 moles of Mg is reaction with 16.60 moles of HCl, quantity which is over our available 13.5 moles of HCl. The limiting reactant is HCl.

Knowing this we devise the following reasoning:

if         2 moles of HCl produces 1 mole of  H₂

then    13.5 moles of HCl produces X moles of  H₂

X = (13.5 × 1) / 2 = 6.75 moles of H₂

Use pv=nrT


where p is the pressure,
v is the volume,
n is the number of mole (which can be equal to mass /mr),
T is the temperature in kelvin,
and r is (molar constant) = 8.31 (units)

A wildfire can destroy thousands of acres of forest. Explain two positive effects and two negative effects that a wildfire can h
Lynna [10]

Explanation:

Wildfires destroy forests that are great carbon sinks. This means that large amount of carbon dioxide are released back into the atmosphere. Carbon dioxide is a greenhouse gas and this will contribute to global warming.

An advantage is that the wildfire will spur secondary ecological succession. This kind of succession improves the biodiversity of the forest. Biodiversity improves the productivity of the ecosystem.
