(select all that apply.) choose the main components of an ecosystem.

The main parts of an ecosystem may be labeled: the sun; soil, water, and climate; green plants (food producers); herbivorous (plant-eating) animals; carnivorous (flesh-eating) animals; and decomposers (fire, fungi, and bacteria).

Explanation:

1.376 moles ZnCl₂

Explanation:

Based on the reaction:

ZnO + 2HCl → ZnCl₂ + H₂O

1 mole of ZnO reacts with 2 moles of HCl to produce 1 mole of ZnCl₂.

To solve this question we need to convert the mass of ZnO to moles using its molar mass (ZnO = 81.38g/mol). The moles of ZnO added are the moles of ZnCl₂ produced (1mole of ZnO produce 1 mole of ZnCl₂):

Moles ZnO = Moles ZnCl₂:

112g ZnO * (1mol / 81.38g) = 1.376 moles ZnCl₂
