You carefully place lettered candy with the letters facing up in water. Without disturbing the water, you notice the letters flo

at above the candy as the solution process takes place. Discuss why this would happen in terms of soluble, insoluble, miscible, immiscible, and water as the universal solvent. Describe the general conditions under which solids are most soluble in liquids.

Oil-based food coloring used to make the letters, won't dissolve in water. According to some sources, oil-based food coloring is either insoluble or immiscible in water. Because it is present in more solutions, water serves as the universal solvent.

<h3>Universal solvent:-</h3>

A substance that displaces most compounds is known as a universal solvent. Because it dissolves more chemicals than any other solvent, water is known as the universal solvent.

<h3>What chemicals lack solvability?</h3>

Sand, plastic, wood, metal, glass, and cloth are examples of insoluble materials. At standard conditions of pressure and temperature, these compounds never dissolve in water or any other solvent. Other examples of insoluble materials are sugars and inorganic salts.

2A → B + C The above reaction is run and it is found that a plot of the natural log of the concentration versus time is linear.
Alex17521 [72]

Answer:

zero order reaction

Explanation:

The seem to be a reaction is zero order as the data only fits to zero order integrated rate law.

Integrated rate law:

[A] = [A]_0 – kt

Here y = [ A] and slope is -k , so when we plot concentration of A with respect to t then we get the equation in the form of line

y = mx + c

So the answer Zero order in [A]

Water is produced from the reaction of hydrogen and oxygen gas, according to the equation below. What is the excess reactant in
liq [111]

Explanation:

Mole ratio of Oxygen to Hydrogen gas = 1 : 2.

If we use 3.0 moles of oxygen gas, we would need 3.0 * 2 = 6.0 mol of hydrogen gas.

However we only have 4.2 mol of hydrogen. Therefore hydrogen is limiting and oxygen is in excess. (B)

What sort of nucleophile does NADH supply?
Elden [556K]

Answer:

Hydride ion

Explanation:

You often see the reduction with NADH written as

NADH ⟶ NAD⁺ + H⁺ + 2e⁻

If you think about it, H⁺ + 2e⁻ is equivalent to H:⁻, so we could write the reaction as

NADH ⟶ NAD⁺ + H:⁻

In terms of a mechanism, the dihydropyridine ring of NADH transfers a hydrogen atom with its pair of electrons (a hydride ion) to the substrate and becomes the more stable, aromatic pyridinium ion in NAD⁺.
