Answer:
8.1m/s2
Explanation:
The following were obtained from the question:
V = 24.3m/s
t = 3secs
a =?
a = V / t
a = 24.3 / 3
a = 8.1m/s2
Answer:
Final concentration = 0.019 M
Explanation:
Initial Concentration [A]o = 0.27M
Rate constant, k = 0.75 s^-1
Final concentration [A] = ?
Time, t = 1.5s
The relationship between the variables is given by the equation;
ln[A] = ln[A]o - kt
ln[A] = ln(0.27) - (0.75)(1.5)
ln[A] = - 1.309 - 1.125
ln[A] = - 2.434
[A] = 0.019 M
Answer:
235L
Explanation:
PV =nRT
V = nRT/P
47.20 °C is 320.35K
V = (79.5 mol)(0.0821 atm•L/mol•K)(320.35K)/8.91atm
V = 234.6698577L
Round to 3 sig figs: 235L
Answer:
2H2 + O2 = 2H2O
This implies that 2 moles of oxygen is needed to react with one mole of oxygen to form 2 moles of water
It also implies that
2moles of hydrogen requires 32 grams of oxygen
?moles of hydrogen would require 8g of oxygen
2x8/32 = 0.5moles//
