I would say option A - The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.
Explanation:
Firework exploding is a regular chemical reaction chain which ones started does not stop till the chain is complete. The action is rapid and cannot be stopped in the middle as compared to candle burning.
Answer:
B
Explanation:
Grass obtains energy through photosynthesis. Grass produces glucose and oxygen, which in short, animals and us take in.
Answer:
Final temperature, T2 = 2460 Kelvin.
Explanation:
Given the following data;
Initial pressure = 1atm
Final pressure = 2.7atm
Initial temperature = 911K
To find the final temperature, we would use Gay Lussac's law;
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;

Making T2 as the subject formula, we have;
Substituting into the equation, we have;


Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
