Answer:
12
Explanation:
If GT bisects BN at point G, then point G would be in the middle of BN. So, since Bg and NG have to be equal and add up to 24, then the answer is 12.
The particles bunch together and can no longer move
Answer:
2.5 atm
Explanation:
P2 = 1.2 atm x 2.65 L x 345 K / 1.5 L x 298 K
Esto debería ser igual...
2.45 atm (personajes importantes)
Answer:
C. +5
Explanation:
Oxygen is always -2. And the sum of the oxidation numbers must be equal to the charge. So:
2x + 7(-2) = -4
2x - 14 = -4
2x = 10
x=5
Answer:
molar mass of C₃H
₈ = 44 g/mole
Explanation:
Computation of the amount of oxygen that reacts
.
⇒ 75 - 12.5
⇒ 62.5 cm³
Computation of proportion of hydrocarbons
2 mole hydrocarbons 3n+1 oxygen
⇒ 3 n + 1 = [62.5 × 2] / 12.5
⇒ 3 n + 1 = 10
⇒ n = 3
So,
Formula of the hydrocarbon is C₃H
₈
Computation of molar mass of C₃H
₈
⇒ [12×3] + [1×8]
⇒ 44 g/mole
