Tell the teacher while running to the sink. Wash your burn with water for a long time, but do not use soap because the chemical could react with the soap.

In addition to carbon, carbonate minerals contain
shutvik [7]
Carbonate groups contain a single carbon atom, and three oxygen atoms in a trigonal molecular geometry. The carbon atom has two single bonds to two oxygen atoms and a double bond to the third oxygen atom. Therefore, in addition to carbon, carbonate minerals contain oxygen. An example of a carbonate mineral is calcium carbonate, often found within rocks.

Athletes and physically active people have increased needs for
STALIN [3.7K]
They have increased need to carbohydrates, protein, water and iron.

Carbohydrates is the primary source for energy and active people apparently need more energy for their daily activities.

Protein helps build muscles, even though they only need a small amount more of protein than normal people, they still require protein for muscle buildings.

Water has to be needed as they may excrete more sweat by active activities in the day time. Water can also help remove waster material from body.

Iron helps the production of hemoglobin, which is in the red blood cells that help transport oxygen. As they exercise more, they need more oxygen supply for respiration, therefore there is a need for iron supply.

Your friend brings you rocks with a thick layer of oxidation weathering, and no other visible signs of weathering. this is a clu
Vsevolod [243]
<span>A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. There are three types of weathering, physical, chemical, and biological. For the physical weathering, there are two main types. Freeze-thaw cycles and exfoliation. Obviously the freeze-thaw cycles require water and the exfoliation generally happens through thermal expansion and contraction which doesn't require water. But since neither of these mechanisms were observed, that doesn't indicate if the area was wet or dry. Biological weathering is caused by plants or animals breaking down rocks via chemical (acid) or mechanical (root growth) means. Life generally indicates the presence of water, but since this form of weathering wasn't observed, we still don't have enough data. Chemical weathering is caused by rain water reacting with the rocks to form new minerals and salts. There are several types such as acidic rainwater dissolving part of the rock, and oxidation. With this in mind, let's take a look at the available options. A moist environment because there is a greater density of oxygen in the atmosphere in the presence of water. * Yes, we need a moist environment, but the density of oxygen is fairly constant world wide regardless of how moist or dry the environment is. So this is a bad choice. A moist environment because physical weathering processes such as oxidation take place most quickly in the presence of water. * Water speeds up chemical weathering of all types. So this is the correct choice. A dry environment because the increased albedo of deserts encourages physical weathering processes such as oxidation. * Yes, the increased albedo of deserts does speed up spalling, but oxidation is a CHEMICAL weathering process, not a PHYSICAL one. So this is a bad choice. A dry environment because in the absence of water oxidation is the dominant weathering process. * Water speeds up oxidation quite a bit. And since the observed oxidation is thick, there's been quite a bit of weathering. So this is a bad choice.</span>
