Answer:

Substances over 7 are categorized as basic, with 7 being the neutral point. Water has a pH level of 7. Substances with pH levels under 7 are categorized as acidic. Vinegar is acidic.

Explanation:

You can change it a little if you want. Hope this helps!

Vinegar is acidic. The only vinegar that has alkaline is apple cider vinegar, but all types of vinegar are acidic.

Answer:

Precipitation reactions are ones in which at least one of the reactants is in the aqueous phase (i.e., dissolved in water), and a solid forms on the product side which was not present on the reactant side. If all the reactants are solid, then a solid product forming should not be called a precipitate. To be called a precipitate, an insoluble product must form from within solution, either from a solid and solute interacting, or from an interaction strictly between solutes.

Answer:

a. decrease the amount of the common ion in the system

Explanation:

The correct option is - a. decrease the amount of the common ion in the system

Reason -

Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.

Adding a common ion to a dissociation reaction causes the equilibrium to shift left, toward the reactants, causing precipitation.

Answer:  The coefficient we should change first is for [tex]NO_{3}[/tex].

Explanation:

The given reaction equation is as follows.

[tex]Al + Ni(NO_{3})_{2} \rightarrow Al(NO_{3})_{3} + Ni[/tex]

Here, number of atoms present on reactant side are as follows.

Number of atoms present on the product side are as follows.

To balance this equation, multiply Al by 2 and [tex]NO_{3}[/tex] by 3 on reactant side. Also, multiply [tex]Al(NO_{3})_{3}[/tex] by 2 and Ni by 3 on the product side.

Hence, the equation can be rewritten as follows.

[tex]2Al + 3Ni(NO_{3})_{2} \rightarrow 2Al(NO_{3})_{3} + 3Ni[/tex]

Now, number of atoms present on reactant side are as follows.

Number of atoms present on product side are as follows.

Since, the atoms on both reactant and product side are same. Hence, it is now a balanced chemical equation.

Thus, we can conclude that the coefficient we should change first is for [tex]NO_{3}[/tex].

Answer:

1. This reaction is (A) Exothermic .

2. When the temperature is decreased the equilibrium constant, K: (A) Increases

3.When the temperature is decreased the equilibrium concentration of Co2: (A) Increases

Explanation:

[tex]CoCl4^2-(aq) <--> Co_2+(aq) + 4Cl^-(aq)[/tex]

1. The pink color predominates at low temperatures, indicating that the commodity is preferred.

This is a reaction that is exothermic.

2. As the decrease in the temperature , the equilibrium constant , K ;

      equilibrium constant = [tex]\frac{product}{reactant}[/tex] =[tex]\frac{[CO^2^+][Cl^-^4]}{CoCl^2^-_4}[/tex]

As the temperature drops, the concentration of[tex]Cl^-[/tex] and [tex]CO^2^+[/tex] rises, and K rises as well , thus it increases .

3. The equilibrium concentration of [tex]CO^2^+[/tex] decreases as the temperature decreases:

When the temperature is lowered, the equilibrium shifts to the right , that is it increases.

Explanation:

Answer:

a) water expands when it freezes and damages the cell wall.

Explanation:

We know that most liquids expand when heated and contract when cooled. Water does not behave in the same way.

Water contracts on cooling from any temperature until 4°C when it begins to expand until 0°C. Hence a given mass of water has its least volume and highest density at 4°C.

Hence, fresh vegetables with high water content do not freeze well because water expands when it freezes and damages the cell wall.

Answer:

Antarctic Peninsula, is one of the most important fossil sites on Earth.

hope this helps you ☺️☺️

Fossils that would be expected to be found in Antarctica from more recent times, after it had moved much closer to the South Pole is Antartica peninsula.

Fossils are the preserved remains, impression, or trace of any once-living thing from many years ago. Examples of the fossils include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants.

There are four different types of fossils-

Mold fossils

Cast fossils

Trace fossils or Ichnofossils

True form fossils

Imprints, tracks, and trails can also become fossilized and are called Trace fossils. Dinosaur footprints or worm burrows are the examples.

Living things when get decomposed from the so many years ago and become dirt and rocks are fossils.

Therefore, Fossils that would be expected to be found in Antarctica from more recent times, after it had moved much closer to the South Pole is Antartica peninsula.

Using ideal gas law–

We'll use formula,

PV = nRT

Where,

P, Pressure = 1.40 atm

V, Volume = 42.4 L

n, Number of moles = ( To find ) ?

T, temperature = 25°C

R, Ideal gas constant = 0.08206 L . atm/k. Mol

Answer:

A

Explanation:

A scientist is a person who conducts scientific research to advance knowledge in an area of interest.

In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. It was not until the 19th century that the term scientist came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833.

Please find the report on the comet below

Explanation:

Specifically in the year 1993, a comet was discovered by three individuals namely: Eugene Shoemaker, Carolyn Shoemaker, and David Levy. The comet was named after the first discoverers as; Shoemaker-Levy 9.

Shoemaker-Levy 9 was reported to have already been in pieces as at the time of discovery. It was believed to have been torn apart by the gravitational force emanating from the biggest of the planets called JUPITER.

In July 1994, Shoemaker-Levy 9 came in contact with Jupiter in what seemed to be the end of the discovered comet. This collision of Shoemaker-Levy 9 with planet Jupiter was said to be the first ever solar systems collision observed.

Answer:

a. 0.026 M

Explanation:

Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:

Molarity = n/V

Where;

n = number of moles (mol)

V = Volume of solution (L)

Based on the information provided;

V = 23.2mL = 23.2/1000 = 0.0232 L

n = ?

To get the number of moles of KHP, we use the formula:

mole = mass/molar mass

mole (n) = 0.123/204.2

mole (n) = 0.0006024mol

Molarity = n/V

Molarity = 0.0006024 ÷ 0.0232

Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2

Molarity = 6.024/2.32 × 10^(-4--2)

Molarity = 2.59 × 10^-2

Molarity = 0.026 M
