I’m pretty sure this is right
The thermosphere is the layer in the Earths atmosphere directly above the mesosphere and below the exosphere. Within the layer of atmosphere, ultraviolet radiation causes photoionization of molecules creating ions the thermosphere continues the larger part of the Ionosphere.
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.
As the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
<h3>
Acceleration of the objects</h3>
The acceleration of the objects is determined from Newton's second law of motion as follows;
F = ma
a = F/m
<h3>for mass of 5 kg and force of 2 N</h3>
a = 2/5 = 0.4 m/s²
<h3>for mass of 7 kg and force of 4 N</h3>
a = 4/7 = 0.57 m/s²
<h3>for mass of 10 kg and force of 6 N</h3>
a = 6/10 = 0.6 m/s²
Thus, from the data above we can conclude that, as the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
