Answer:
Density=2kg/6m^3=1/3 kg/m^3
Explanation:
Answer:
The values are:
6.55 mmHg
0.00862 atm
Explanation:
This is all about unit conversion
760 mmHg = 760 Torr
1 atm = 760 Torr
6.55 Torr . 760 mmHg / 760 Torr = 6.55 mmHg
6.55 Torr . 1 atm / 760 Torr = 0.00862 atm
He is making an alloy and getting rid of impurities.
Skeletal Equation
Ba(NO3)2 + KCl = BaCl2+ KNO3
Balanced equation
Ba(NO3)2 + 2KCl = BaCl2 + 2KNO3
Answer:
0.3 mol A is combined with 0.8 mol B.
Explanation:
Limiting reagent in a chemical reaction is defined as the reagent that is totally consumed when the chemical reaction is complete.
In the reaction:
A + 2B → 2C+D
For a reaction of 1 mole of A, you need two moles of B. That means for any quantity of A you need twice this quantity in B.
Thus, <em>A is limiting reagent when moles of B are higher than twice moles of A.</em>
* 0.5 mol A is combined with 0.3 mol B. Twice moles of A are 1.0 moles that are higher than 0.3 moles. <em>A is not limitng reagent.</em>
* 0.5 mol A is combined with 0.6 mol B. Twice moles of A are 1.0 moles that are higher than 0.6 moles. <em>A is not limitng reagent.</em>
* 0.2 mol A is combined with 0.3 mol B. Twice moles of A are 0.4 moles that are higher than 0.3 moles. <em>A is not limitng reagent.</em>
* 0.3 mol A is combined with 0.8 mol B. Twice moles of A are 0.6 moles that are lower than 0.8 moles. <em>A IS limitng reagent.</em>
