Answer:
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:
The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.
Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.
In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.
Answer:
the evidence points to increase of carbon dioxide in the atmosphere. There are many reasons, but you could probably go with deforestation, unregulated emissions--burning fossil fuels, industry and transportation.
<em>Answer:</em>
<em>In addition, both plant and animal cells store energy by shunting glucose into fat synthesis pathways. One gram of fat contains nearly six times the energy of the same amount of glycogen, but the energy from fat is less readily available than that from glycogen.</em>

Answer: 45 J
Explanation:
The formula for work is force x distance.
W = fd
W = (30 N)(1.5 m)
W = 45 J
Answer:
euphoria
Explanation:
When a person takes alcohol, he/she feels relaxed and euphoric. This happens because of the release of endorphins. Endorphins are a chemical that produces the feeling of pleasure and happiness. After the first drink, the content of alcohol in blood is 0.05-0.06% which is sufficient to develop euphoric feeling.
However, some of the consumers have also claimed that it act as a depressant.
