The graph below compares the rates of reaction of a burning candle and an exploding firework.

comparing chemical reactions
a graph has time on the horizontal axis and concentration of reactants on the vertical axis. for an exploding firework, the concentration starts high, increases slightly and then decreases rapidly. for a burning candle the concentration starts high, increases more than the firework, and then decreases rapidly. the concentration for the burning candle is higher than the firework at all timepoints.

what can you conclude from the graph?

answer: the statements that hold true for the exploding firework and a burning candle are:

the reaction of an exploding firework occurs at a faster rate than a burning candle. the reaction occurs at a very fast rate leading to a build up of the gases at the core of the firework. this build up leads to the explosion to release all the gases into the atmosphere.

the activation energy required for an exploding firework is less than the activation energy required for a burning candle. the firework requires only a small flame or a spark to quickly ignite it whereas a full flame is required to light a candle.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
