Do algae release oxygen?
Do algae release oxygen? Like most plants, many algae produce oxygen during the daylight as a by-product of photosynthesis. At night these algae consume oxygen, but usually much less than was produced during the daylight. How can algae decrease oxygen levels? The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants. When the […]
Is rate of reaction slower or faster?
Is rate of reaction slower or faster? The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands, of years while others […]
What happens on a molecular level?
What happens on a molecular level? On the molecular level, the individual chemical bonds in the substance are not altered; hence, a phase change is not a chemical reaction. Instead, the molecules experience a decrease in potential energy in an endothermic phase change. What happens on a molecular level when water freezes? Point out that […]
Is Moon getting brighter?
Is Moon getting brighter? When the Earth (and therefore the Moon) is at its perihelion, the closest point in its orbit to the Sun, the sunlight that reflects off the Moon is slightly more intense, causing the full moon’s brightness to increase by about 4%, which is imperceptible by the human eye. Do gamma rays […]
Why do conifer seeds have wings?
Why do conifer seeds have wings? Early trees had wind-borne spores rather than seeds. About 365 million years ago some plants evolved seeds with a food store, to give the developing embryo a head start. These were heavier, so the early conifers began to evolve seed coats with enlarged ribs or vanes to help catch […]
Do ovens use a lot of electricity?
What happens when many water molecules come into contact with one another?
What happens when many water molecules come into contact with one another? What happens when 2 water molecules come in contact with each other, does the orientation of the water molecules matter? When they come into contact with each other they are attracted to each other and the orientation matters because the Hydrogen of one […]
