Adding water to acid that's kind of dangerous
Answer:
The objects mass is 84, 105 g. See the explanation below, please.
Explanation:
We use the formula:
Density= mass/volume
Mass= Density x volume =0.801 g/mL x 105 mL = 84, 105 g
the answer i believe is b:saltation, which is a form of wind erosion
The correct answer is that the energy will be transferred
into the system and as well as the solubility of lithium chloride will likely
increase. It Is because LiCl is soluble when is dispersed in hot water that is
why the solubility of lithium chloride will increase and that the heating
solution will likely transfer the heat energy in the system in which the energy
will be transferred in the system is correct.
Answer:
2 moles of MgCl2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
Mg + 2HCl —> MgCl2 + H2
Now, we can determine the number of mole MgCl2 produced from 4 moles of HCl as follow:
From the balanced equation above,
2 moles of HCl reacted to produce 1 mole of MgCl2.
Therefore, 4 moles of HCl will react to produce = (4 x 1)/2 = 2 moles of MgCl2.
Therefore, 2 moles of MgCl2 were produced from the reaction of 4 moles of HCl.
