Answer:
Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.
Explanation:
By the reaction
H2+ 1/2 O2 → H2O
Moles of O2 = 5.2\32
⇒1 mole of O2 produce 1 mole of H2O
1 mole O2 will produce 2 mole of H2O
Therefore, 5.2\32 mole will produce 
⇒ Molecules of H2O will be
= 
= 1.956×10^22 moleculesof H2O.
N = m/M
= 200g/(12.01g/mol + 2(16.00g/mol))
=4.54mol
Answer:
True.
Explanation:
Now i'm not 100% sure if this is the answer but i believe depending on what you are making/mixing would depend on the answer, this answer probably won't be the same in context of slim making but it could mean true for other things, so without knowing much i would guess True.
Im pretty sure it would be d.
Answer:
R = 12 ohms
Explanation:
It is given that,
Supply voltage is 12 V
Current in the circuit is 1 A
We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :
V = IR
So, the resistance of the circuit R is 12 ohms.
