Charles law states that there is a directly proportional relationship between the volume and the temperature of the gas at certain pressure.
Therefore,
V1/T1 = V2/T2
V1 is unknown
T1 = 159K
V2 = 15.5m3
T2 = 456K
V1/159 = 15.5/456
V1 = (15.5*159)/456 = 5.404m3.
When the volume of a gas is changed from 5.404 m3 to 15.5 m3 the temperature will change from 159 K to 456 K.
The correct answer is B) Double displacement.
This is because the Barium (Ba), which has a positive charge, got rearranged to bond with the carbonate (CO3), which has a negative charge. Also, the potassium (K), which has a positive charge, bonded with the chlorine (Cl), which has a negative charge.
It helps to remember that when there is a double replacement there are 4 elements/molecules in the reactants and 4 in the products that get rearranged.
Hope this helps!
14.478 is correct if it says it's not correct try rounding
1.5 M KNO3 - both solutions contain KNO3, but the one with higher concentration is 1.5 M, as 1.5 M > 1.0 M. 1.0 M also increases the boiling point, but not to as great an extent as 1.5 M does.
Answer:
The answer to your question is:
a) 36 g of water
Explanation:
MW SO₂ = 32 + 32 = 64 g
MW Br = 80 g
MW H₂O = 18 g
MW HBr = 81 g
MW H₂SO₄ = 98
Balanced reaction:
SO₂ + 2Br + 2H₂O ⇒ 2HBr + H₂SO₄
64g 2(80) 2(18) 2(81) 98
64.1 159.9 161.9 98.1
Rule of three with Br and H2O
160 g ---------------- 36 g
160 ------------------- x
x = 160(36)/160 = 36 g oh water
