Explanation:
A 57.9 g sample of glass is cooled by 2.70'C how much heat does it release
1560
Answer:
0.7 moles of Chlorine gas is required.
Explanation:
The reaction is balanced as follows:
2Na +
------> 2NaCl
According to stoichiometry,
2 mole Sodium reacts with 1 mole Chlorine gas
∴1 mole Sodium reacts with 1/2 moles of Chlorine gas
∴1.4 mole sodium reacts with 1.4/2 moles of Chlorine gas
= 0.7 moles of Chlorine gas
So, 0.7 moles of Chlorine gas is required.
Answer:
when he collided with the passerby
Explanation:
Answer:
≈ 0.10M
Explanation:
[A]o = 0.27M
Rate constant, k = 0.75 s−1
[A] = ?
time, t = 1.3
Integrated formular for a first order reaction is given as;
ln[A] = ln[A]o − kt
ln[A] = ln(0.27) - 0.75(1.3)
ln[A] = -1.309 - 0.975
ln[A] = -2.284
[A] = 0.1019M ≈ 0.10M
