Answer:
The answer to your question is: 3000 cm
Explanation:
30 meters long to cm
We can use a rule of three to solve it
We know that 1 meter ------------------ 100 cm
30 meters ---------------- x
x = 30(100)/1 = 3000 cm
Answer:
151.4863 years
Explanation:
Half life, t1/2 = 100 years
Initial concentration,[A]o = 100%
Final concentration, [A] = 35% (after 65% have been decayed)
Time = ?
Half life for a first Order reaction is given as;
t1/2 = ln (2) / k
k = ln(2) / 100
k = 0.00693y-1
The integral rate law for first order reactions is given as;
ln[A] = ln[A]o − kt
kt = ln[A]o - ln[A]
t = ( ln[A]o - ln[A]) / k
t = [ln(100) - ln(35)] /0.00693
t = 1.0498 / 0.00693
t = 151.4863 years

Carbon monoxide is produced in an engine
when incomplete combustion happened. In a combustion engine intake valve, it
combines the fuel and air (nitrogen and oxygen) and when spark plug ignites it
pushes the piston downwards. After that piston will push itself upward and
pushes the air that was generated by the combination of those components in the
exhaust valve. This is a repeated cycle which keeps the engine running. In a
perfect combustion process the air being released are carbon dioxide, water and
nitrogen. But when an incorrect ratio of the combination of fuel and air in the
engine is processed, carbon monoxide is being generated.
