Answer:
56160grams
Explanation:
First, we need to convert the number of molecules of magnesium chloride (MgCl2) into moles by dividing by Avagadro's number (6.02 × 10^23 molecules)
n = nA ÷ 6.02 × 10^23
n = 14.07 × 10^26 ÷ 6.02 × 10^23
n = 14.07/6.02 × 10^(26-23)
n = 2.34 × 10^3 moles of MgCl2
The balanced reaction given in the question is as follows:
Mg + 2HCl → MgCl2 + H2
If 1 mole of Mg produced 1 mole of MgCl2
Then, 2.34 × 10^3 moles of Mg will also produce 2.34 × 10^3 moles of MgCl2.
Using mole = mass ÷ molar mass (MM)
Molar mass of Mg = 24g/mol
mass = mole × MM
mass = 2.34 × 10^3 × 24
mass = 56.16 × 10^3
mass = 56160grams.
Answer:
The SI unit for specific enthalpy is joule per kilogram. It can be expressed in other specific quantities by h = u + pv, where u is the specific internal energy, p is the pressure, and v is specific volume, which is equal to 1ρ, where ρ is the density.
Explanation:
Answer;
-Distillation
Explanation;
Distillation is a technique that can be used to physically separate most homogeneous mixtures based on the difference in the boiling points of the substances involved.
A good example; A flask hold liquids A, B, and C in a homogeneous mixture. The boiling points of A, B, and C are 130 C, 65 C, and 71 C, respectively. The flask is heated to 65C until all of liquid B is filtered out. The remaining mixture is heated to 71C until all of liquid C is filtered out, and only liquid A is left in the flask.
According to google, "As keratin cells naturally push upward through the skin, they die and then harden, turning into your hair or nails."
