Answer:
I want to say your answer is B)
Answer:
Because the reaction is endothermic, and because of that, it is necessary to warm up the solution, to achieve more dissolution
Explanation:
The chemical reactions can be exothermic or endothermic. In the first one, the system loses heat for the surroundings, so the temperature of the surroundings is increasing, and the system is decreasing.
In the endothermic reactions, the system is absorbing heat for the surroundings, so its temperature is increasing, and the temperature of the surroundings is decreasing.
Note that the flow heat only occurs when there is a difference in temperature because the system and the surroundings intend to the thermal equilibrium. So, for exothermic reactions, to control them and let them achieve the maximum conversion, is ideal to cool down the solution, so the reaction will lose more heat; and for endothermic reactions, it is ideal to warm up the solution, so the reaction can absorb more heat.
So, the reaction of the dissolve of the antiacid tablet is endothermic, and because of that, it is necessary to warm up the solution, to achieve more dissolution.
They want you pick choice-B, but it's a terribly corrupted example.
Newton came 100 years AFTER Kepler.
Furthermore, he didn't USE Kepler's laws to work out his law of gravity, but once he HAD his law of gravity, he was able to use IT to show why Kepler's laws must be true.
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids)
Explanation:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. ... Biological macromolecules are organic, meaning that they contain carbon.
Answer: -
Zero
Explanation: -
Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.
The double bond equivalent for an organic compound can be found out by the help of the formula
DBE = C+1 -0.5 H - 0.5 X + 0.5 N
The chemical formula of the compound B = C₇H₁₆O
So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.
Plugging into the formula,
DBE = 7 + 1 - 0.5 x 16
= 0
Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O
