Answer:
0.0006 mole
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.100 M
Volume = 6.0 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 6.0×10⁻³ L
Thus, moles of potassium iodide :
Moles of HCl = 0.0006 moles
From the reaction shown below:-
1 mole of HCl reacts with 1 mole of sodium carbonate.
So,
0.0006 mole of HCl reacts with 0.0006 mole of sodium carbonate.
<u>Moles of sodium carbonate = 0.0006 moles</u>
Answer:
Magnesium atom, Mg is oxidized
Explanation:
This is because it loses electrons to form msgnesium ion.
Answer:
The volume of the gas at a pressure of 65.0 kPa would be 363 mL
Explanation:
Boyle's Law is a gas law that relates the pressure and volume of a certain amount of gas, without temperature variation, that is, at constant temperature.
Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant. In other words, the product P · V remains constant at the same temperature:
P*V=k
Being P1 and V1 the pressure and volume in state 1 and P2 and V2 the pressure and volume in state 2 are fulfilled:
P1*V1=P2*V2
In this case:
Replacing:
45,000 Pa* 0.525 L= 65,000 Pa*V2
Solving:
V2=0.363 L=363 mL
<u><em>The volume of the gas at a pressure of 65.0 kPa would be 363 mL</em></u>
