Number of moles of HCl =
=
= 0.763 mole
From balanced equation:
4 moles of HCl give 2 moles Cl2
0.763 mole HCl give ?? mole Cl2
by cross multiplication :
= 0.38 mole Cl2
mass of Cl2 = moles x molar mass = 0.38 x 70.9 = 27 g
The answer is D. Ne, which stands for Neon.
Answer:
the fuel efficiency in kilometers per liter is 16.561 kilometer per liter
Explanation:
The computation of the full efficiency in kilometers per liter is shown below:
39.0 miles ÷ gallon = (39.0 miles ÷ gallon) × (1.6094 km ÷ 1 miles) × (1 gallon ÷ 3.79 L)
Now cut the opposite miles and gallons
So, the fuel efficiency would be
= 16.561 kilometers per liter
Hence, the fuel efficiency in kilometers per liter is 16.561 kilometer per liter
Answer:
c. the soluble compound exists as dissolved ions in a solution while insoluble compound forms as a precipitated.
Explanation:
Let's consider an example of a double displacement reaction that produces a soluble compound and an insoluble one.
BaCl₂(aq) + Na₂SO₄(aq) ⇒ NaCl(aq) + BaSO₄(s)↓
NaCl is a soluble compound so it is dissolved in the solution. It is also an electrolyte so it ionizes in water according to the following equation:
NaCl(aq) ⇒ Na⁺(aq) + Cl⁻(aq)
BaSO₄ is insoluble so it remains as a precipitate.
I think it would be wool fabric, D. Because when you get a piece of wool fabric and rub it against a balloon it creates static electricity. Hope I helped some :)
