Why would a large lump of copper oxide react slower with sulfuric than if copper oxide is used in powdered form?
A large lump of copper oxide has a smaller surface area exposed to the sulfuric acid compared to powdered copper oxide. This limits the contact between the copper oxide and the acid, leading to a slower reaction. Powdered copper oxide has a larger surface area, allowing for more efficient and faster reaction with the sulfuric acid.
Why is granulated zinc used instead of a block?
If there is Block of zinc, only the zinc on the surface gets exposed to the other reactants but if there is granulated zinc because of its more surface area the zinc is more exposed so the granulated zinc is used for the greater reaction rate.
How the reaction of bromine with sodium would compare with the reaction of chlorine with sodium?
The reaction of bromine with sodium would be slower than the reaction of chlorine with sodium, as bromine is less reactive than chlorine. Both reactions would produce a salt (sodium bromide or sodium chloride) and release heat and gas (hydrogen gas in the case of chlorine).
Why would a chemical reaction stop?
Reactions stop because after time there are less reactants so the chemical reaction starts to slow down. As there are less and less reactants the chemical reaction gets slower and slower until it stops.
Why does frozen liver react with hydrogen peroxide more than raw liver?
the frozen liver reaction should have been slower than the liver at room temperature, as this is the optimal condition for the enzyme catalase. The reaction would occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.
The method of extracting minerals that involves digging beneath the surface is referred to as What mining?
This would be underground mining.
What would happen if this baseball was dropped from 100 meters above the surface of the Moon?
It will still drop to the surface, just a bit slower.
Would a higher enzymes concentration make the reaction faster or slower?
Increased enzymes would increase the rate of the reaction up to a certain point. They would reach a point where there are no more reactions to help out.

What happens to your reaction time when you get older?
When you get older, your reaction time becomes naturally slower this is because your body is not at it's fittest peak compared to what it would of been in your youth.

What would happen to the cellular respiration process of the enzyme for one step of the process was missing or defective?
It would cause the reaction to occur at a much slower rate, because all enzymes do is speed up the reaction.
Why and how would you extend the curing process of the concrete?
Placing plastic sheeting (known as visquene in construction trades) over drying concrete extends the curing process of concrete. The idea is to slow the evaporation of moisture from the drying concrete. The slower concrete curing process, the stronger the concrete becomes. On construction jobs I have been party to, the curing concrete is usually covered for two or three days.If the curing concrete's surface were to get dry, there may not be enough water for the chemical reaction which forms concrete, and so the surface would not be as strong. Wetting isn't about "extending" but rather allowing the curing to make a hard surface. The full curing takes as long as a month to reach full strength, but most of the reaction happens in three days.If you actually want it slower, then cooling would work, as with any chemical reaction. Also disrupting the water-cement reaction would work, which would unfortunately make the concrete weaker. For example, adding sugar or anything that ties up the water would slow the reaction but harm the strength of the result.
Why does sound travell faster under water than under ground?
Actually, sound travels slower under water than underground. Sound is a vibration in molecules that we perceive as noise. Water's molecules are rather loose compared to a solid's molecules, so it would travel slower underwater compared to traveling underground.
What would happen to the reaction rate if the toothpicks were not in a neat pile but instead spread out over the lab station?
If the toothpicks are spread out over the lab station instead of piled neatly, the reaction rate would likely decrease. This is because the increased surface area and distance between individual toothpicks would reduce the frequency of collisions between them, leading to fewer interactions and a slower reaction. In a more organized pile, the toothpicks are more likely to come into contact with each other, enhancing the reaction rate.
Would a liquid evaporate slower or faster if you increased the surface area an why?
Increasing the surface area of a liquid would lead to faster evaporation. This is because more molecules on the surface of the liquid would have the opportunity to escape into the gas phase. A larger surface area allows for more efficient evaporation.
Is it warmer underground or on the surface?
It is warmer underground than on the surface because the Earth's inner core is much hotter than the surface. The temperature increases the deeper you go beneath the Earth's surface due to the geothermal heat coming from the Earth's interior.
