Answer:
Ch4 + 2O2 ----> CO2 + 2H2O
Explanation:
Ch4 has 4H, 1C
O2 has 2 O2
CO2 has 1 C, 2O
H2O has 1 H, 2O
you need to add 2 to O2 to balance it. Add 2 to H2O to balance the H and O
The correct term to your question is anion
Answer : The time passed in days is 28.6 days.
Explanation :
Half-life = 14.3 days
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time passed.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = ?
a = let initial amount of the reactant = 100 g
a - x = amount left after decay process = 100 - 75.0 = 25.0 g
Now put all the given values in above equation, we get
Therefore, the time passed in days is 28.6 days.
