The substance that gets dissolved is the solute and the substance that dissolves the solute is the solvent. Example: water is a solvent and salt is a solute
Explanation:
Number of moles equal to the given mass divided by molar mass of the element or compound.
Mathematically, No. of moles =
The given mass is g and molar mass is 24.30 g/mol.
Therefore, calculate the number of moles as follows.
No. of moles =
=
= mol
= mol
or, = 2000 mol
Thus, we can conclude that g of Mg has 2000 moles.
D it is only physical and not chemical
Answer:
Explanation:
Hello there!
In this case, according to the given information and the chemical reaction, whereby iron and hydrochloric acid react in a 1:2 mole ratio, it is firstly necessary to calculate the moles of iron (II) chloride from each reactant in order to figure out the limiting reactant:
In such a way, we infer the maximum moles of FeCl2 product are yielded by HCl, for which it is the limiting reactant. Finally, we calculate the grams of product by using its molar mass as shown below:
