A catalyst affects a chemical reaction by accelerating it. It also offers an alternative way for the reaction to happen that lowers the amount of energy needed.
The highest concentration of water would be found in the 5% solution. The concentration given above is percent of glucose, so the solution contain 5% of glucose and 95% of water. Comparing it to 10% of glucose solution which will have 10% glucose and 90% water, clearly, it is the 5% solution that has the highest amount of water in the solution. <span>Percentage
by a certain unit is the amount of that unit of a component in a mixture per 100 units of the
total mixture. </span>
Time is an independent variable ! xo
In Iron Oxide, mass of oxygen also adds into mass of Iron, so it is greater than the mass of Iron alone
