Answer:
Explanation:
Any densities less than 1g/cm3 will float, while objects with densities over 1g/cm3 will sink.
Answer:
GAY-LUSSAC'S LAW.
Explanation:
P1 = 765 torr
T1 = 23°C = 296K
P2 = 560. torr
T2 = ?
(765 torr)/(296K) = (560. torr)/ T2
T2 = 226 K = -57°C
(B) because it couldn’t turn in to good
Answer:
no it is not a balanced equation
Answer is: mass of barium sulfate is 0.668 grams.
Chemical reaction: BaCl₂ + Na₂SO₄ → BaSO₄<span> + 2NaCl.
V(</span>BaCl₂) = 25.34 mL ÷ 1000 mL/L = 0.02534 L.
c(BaCl₂) = 0.113 mol/L.
n(BaCl₂) = V(BaCl₂) · c(BaCl₂).
n(BaCl₂) = 0.02534 L · 0.113 mol/L.
n(BaCl₂) = 0.00286 mol.
From chemical reaction: n(BaCl₂) : n(BaSO₄) = 1 : 1.
n(BaSO₄) = 0.00286 mol.
m(BaSO₄) = n(BaSO₄) · M(BaSO₄).
m(BaSO₄) = 0.00286 mol · 233.4 g/mol.
m(BaSO₄) = 0.668 g.
