The answer is quartz where the hardness is 7.
Can scratch glass easily. This is where most granites are rated in terms of hardness
<span> An object with a high specific heat would change temperature more slowly than one with low specific heat. Water, for example has a very high specific heat so it requires a lot of energy to heat it up. It also takes a while for water to cool down because it holds that heat for a long time. <3</span>
There was land on that surface before there was water
Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral
There are 3 major stages in cellular respiration, glycolysis, Krebs cycle, and the electron transport chain.
