Answer: molecules of water are produced.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of produce = 3 moles of
Thus 0.707 moles of will produce= of
According to avogadro's law, 1 mole of every substance contains avogadro's number of particles.
Thus 1.06 moles of contains = molecules
Answer:
The concentrations are :
The pH of the solution is 3.15.
Explanation:
Initial
c 0 0
Equilibrium
c-x x x
Solving for x:
x = 0.000702 M
Initially
x 0 0
At equilibrium ;
(x - y) y y
Putting value of x = 0.000702 M
Total concentration of
The pH of the solution :
Chlorofluorocarbons and other halogenated ozone depleting substances are mainly responsible for man made chemical ozone depletion.
Answer:
(a) See below
(b) 103.935 °F; 102.235 °F
Explanation:
The equation relating the temperature to time is
1. Calculate the thermometer readings after 0.5 min and 1 min
(a) After 0.5 min
(b) After 1 min
2. Calculate the thermometer reading after 2.0 min
T₀ =106.321 °F
ΔT = 100 - 106.321 °F = -6.321 °F
t = t - 1, because the cooling starts 1 min late
3. Plot the temperature readings as a function of time.
The graphs are shown below.
16 and 6
Explanation:
the top number will be 16 and the bottom number will be 6
