It’s called densitydependent. It slowly increases then reaches an exponential growth rate and then declines into the negative until it gets to zero where it stabilizes
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.
If one population, such as lets say a hawk decreases the niche, or the importance of an animal or its effect in the ecosystem, on the mice. the mice population increases. or it can be lets say plants and bugs, the lady bug goes away and the other bugs eat the plant
