fats contain no carbon-carbon double bonds, whereas fats contain carbon-carbon double bonds.

1 answer:

8 0

Blank 1: Saturated

Blank 2: Unsaturated

Carbon double bonds mean that there is not the max amount of carbon atoms present in the chain and the word saturated means full

What is the kb of the base po−34 given that a 0. 48m solution of the base has a ph of 12. 70? the equation described by the kb v

podryga [215]

The equation described by the kb value is 5.21 x $10^-^3$ .

The potential of Hydrogen is what pH is formally known as. The negative logarithm of the concentration of H+ ions is known as pH. Thus, the definition of pH as the amount of hydrogen is provided. The hydrogen ion concentration in a solution is described by the pH scale, which also serves as a gauge for the solution's acidity or basicity.

Assuming PO₄³⁻ (the phosphate anion).

PO₄³- + H₂O ==> HPO₄²⁻ + OH⁻

Kb = [HPO₄²⁻][OH⁻] / [PO₄³⁻]

We can find the [OH⁻] from the pH of 12.70.

pH + pOH = 14

14.0 - 12.7 = 1.3 = pOH

[OH] = 1x $10^-^1^.^3$

[OH-] = 5.0x $10^-^2$ M

[HPO₄²⁻] = 5.0x $10^-^2$ M

Kb = (5.0x $10^-^2$ )2 / 0.48

= 2.5x $10^-^3$ / 0.48

Kb = 5.21 x $10^-^3$

When two or more substances combine, but each keeps it own properties,the new combination is called a (an)

Harman [31]

The new combination is called a mixture.

In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.

On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.

Hydrogen gas is produced when zinc reacts with hydrochloric acid. If the actual yield of this reaction is 85%?

Leokris [45]

Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂

One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles

The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles

mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g

The answer is D.
