Answer:
The switch is used to <u>disconnect</u> or <u>connect</u> an electrical circuit. When the switch is on, the circuit is <u>complete</u>, and when the switch is <u>off</u>, the circuit is open. Electrical current exists in the circuit when it is closed, but when it is open, there is no <u>electrical</u> current in the circuit. The switch determines whether the circuit is open and closed.
Answer:
I think it's the second answer --If you increase the acidity..
I hope answer I can answer your question!
The answer to fill in the blank is (igneous)
I hope I helped.
The molecular weight of water is <span>18.01528 g/mol.
So in 2.92 grams there are 2.92/</span>18.01528 = 0.1621 mol of particles.
1 mol contains 6,02214 × 10^<span>23 particles by definition.
So the nr of H2O molecules is </span>0.1621 * 6,02214 × 10^23 = 0,9761 × 10^23.
Every molecule has 2 H atoms, so you have to double that.
2* 0,9761 × 10^23 = 1.952 × 10^23.
Theoretical Yield is an Ideal yield with 100 % conversion of reactant to product. It is in fact a paper work.
While,
Actual Yield is the yield which is obtained experimentally. It is always less than theoretical yield because it is not possible to have 100% conversion of reactants into products. Even some amount of product is lost while handling it during the process.
Percentage Yield is Calculated as,
%age Yield = Actual Yield / Theoretical Yield × 100
Data Given:
Actual Yield = 0.104 g
Theoretical Yield = 0.110 g
Putting Values,
%age Yield = 0.104 g / 0.110 g × 100
%age Yield = 94.54 %
