Answer:
= 1.0593 g
Explanation:
1.1% NaCl by mass, means;
1.1 g per 100 g = 0.011
Therefore; the amount of NaCl present in 93.6 g of the solution is;
= 0.011 × 96.3 g
<u>= 1.0593 g</u>
Answer:
Explanation:
Look at the reaction.
2NH3 ===> N2 + 3H2
It's a molecule that is breaking down to two elements on the periodic table. We used to call such a thing as a simple decomposition.
A compound has more than 1 element that is bonded together. The only one listed that fits the definition is D
It will take the Ne gas approximately 1.2 s to equilibrate between the two sides.
We know that the time taken for a gas to diffuse is dependent on the molar mass of the gas. This is one of the interpretations of Graham's law of diffusion in gases. Thus, Let;
t1 = time taken for Rn to equilibrate = 4.0 s
t2 = time taken for Ne to equilibrate = ?
M1 = molar mass of Rn = 222g/mol
M2 = molar mass of Ne = 20 g/mol
Using
t1/t2 = √M1/M2
4/t2 = √222/20
4/t2 = 3.33
t2 = 4/3.33
t2 = 1.2 seconds

Answer:
A replacement reaction occurs when elements switch places in compounds. This type of reaction involves ions. Generally, more reactive elements replace less reactive elements. A single replacement reaction occurs when one element replaces another element in one compound.
