Answer:
2.61 L
Explanation:
p1v1 = p2v2
p1v1 / p2 = v2
98 * 2 / 75 = v2 = 2.61 L

Answer:
A glass of mineral water is not pure water.
Explanation:
Pure chemical substances
Pouring water into a glass from a bottle
Food and drink may be advertised as ‘pure’. For example, you may see cartons of ‘pure orange juice’ or ‘pure mineral water’. This means that nothing else was added to the orange juice or mineral water during manufacture. However, these substances are not pure to a scientist. In science, a pure substance contains only one element or compound.
Mineral water is mostly water, but there are other substances mixed with it. These are the ingredients that you see listed on the bottle’s label.
In your hand, the ball has higher potential energy than kinetic because it is still off of the ground but it isn't moving so there is no kinetic. As the ball rises, its potential and kinetic energy increases. At its peak, it has very high potential energy and very low kinetic energy. As it falls, the potential energy decreases but kinetic does not.
Answer:
redox reaction
Explanation:
it's the only reaction occurs simultaneously, reduction and oxidation occur at the same time
