Answer:
C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O
Explanation:
Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.
As a result, this is the sole reaction that obeys the general combustion equation.
For a 1st order reaction:
In(n/n0)= -k * (time difference)
so k= - In (n/n0)/ (t/t0)
n is concentration at time t and n0 is the concentration at an earlier time t0.
where k is constant.
Answer:
fluoride ion
Explanation:
If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
hope that helps!
Answer:
Catalyze
Explanation:
Catalysis is defined as<em> the acceleration the of the rate of a chemical reaction</em>, enzymes are natural catalysts that can make more efficient, faster reactions by using less energy and generating less waste.
