Answer:
During a chemical reaction, substance called reactants are combined to form a new substance called products.
this sentence describes reaction and products of a chemical reaction
The volume<span> of </span>gas<span> because of the </span>increase<span> and decrease in the speed in which the molecules bounce around. ... Boyle's Law states that if temperature stays the same, the </span>amount of<span> space a </span>gas takes up will increase<span> if the </span>pressure<span> decreases. The </span>amount of gas<span> will take up less space if the </span>pressure<span> is increased. this would be the correct answer </span>
Answer:
138.6 g of C₂HF₃O₂ have 38.9 g of O
Explanation:
Trifluoroacetic acid → C₂HF₃O₂
Molar mass = Mass of C . 2 + Mass of H + Mass of F . 3 + Mass of O .2
Molar mass = 12 . 2 + 1 . 1 + 19 . 3 + 16 . 2 = 114 g /mol
1 mol of C₂HF₃O₂ has:
2 moles of C
1 mol of H
3 moles of F
2 moles of O
If we state the relation in mass by g we say:
114 g of C₂HF₃O₂ have 24g of C, 1 g of H, 57 g of F and 32 g of O
Let's make a rule of three:
32 g of O are contained in 114 g of C₂HF₃O₂
38.9 g of O may be contained in (38.9 . 114) / 32 = 138.6 g
The reaction between m-cresol and sodium hydroxide will create sodium m-cresolate and water.
<h3>What is organic creation?</h3>
The structure of the organic creation (sodium m-cresolate) and the reaction is described in the attached picture.
- In the late 1700s and earlier 1800s, organic biological products were isolated by Scheele, and Chevreuil dissolved carboxylic acids from the saponification of fats. Organic chemistry had formed. Lavoisier invented and Berzelius enhanced combustion research for the organic description.
- Organic Chemistry was first diagnosed as a branch of modern science in the earlier 1800s by Jon Jacob Berzelius. He compartmentalized chemical combinations into two groups-organic and inorganic, representing if they came from minerals or non-living significance.
- Organic chemistry is important because it is the study of life and all of the chemical responses related to life. Several professions apply an interpretation of organic chemistry, such as doctors, veterinarians, dentists, pharmacologists, chemical makers, and chemists.

Answer:
the drops of liquid are coming from the decreases. they are formed as the motion of the water particles in the air gas. this change in motion cause air in the air to change from a liquid to a water
