Answer and explanation:

It is said that an ecosystem is balanced when there is a functional system that helps the prompt recovery of wildlife after some natural event of disastrous characteristics.

This means that it is necessary to have flora and fauna in good condition, with a food chain of predators and preys, that toxic gases have decreased or disappeared, among other issues. We will find a balanced ecosystem when the relationship between natural organisms and human beings is pleasant and harmonic enough and does not imply a risk to nature and its conservation.

A student is collecting the gas produced
marissa [1.9K]

Answer:

0.062 moles of hydrogen gas

Explanation:

We must first out down the reaction equation before we can attempt to solve the problem.

Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)

Next we obtain the number of moles in 1.5 g of magnesium metal from;

Molar mass of magnesium = 24.3 gmol-1

Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles

From the reaction equation;

1 mole of magnesium metal yields 1 mole of hydrogen gas

0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas

Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.

but it gets harder because of the world around it changing. this means that it has to adapt to a lot of things.
