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.
In this case, the physiotherapist is using Constraint-induced movement therapy.
In Constraint-induced movement therapy, the therapist forces the use of the affected arm, by restricting the movement of the arm. In this condition, the therapist block all the possible to work with an unaffected arm, which force the person to use the other arm, and hence, it helps in restoring the movement of the affected arm.
The direction that an ocean current travels can be altered by the movement of the Earth's rotation on its axis. This is known as the Coriolis effect.
<h3>What is Coriolis effect in simple terms?</h3>
Coriolis effect is the result of Earth's rotation on weather patterns and ocean currents. The Coriolis effect makes storms swirl in the clockwise direction in the Southern hemisphere while on the other hand, storms counterclockwise in the Northern Hemisphere. This effect can cause change in the direction of the ocean current due to the rotation on its axis.
So we can conclude that the direction that an ocean current travels can be altered by the movement of the Earth's rotation on its axis. This is known as the Coriolis effect.

The oxygen produced by the chloroplasts passes out the cell by Cellular Respiration. So the answer would be D :)
