Milk is a more uniform mixture after undergoing what?

1. When an acid reacts with a base, what compounds are formed? (1 point) a salt only water only metal oxides only a salt and wat

scoundrel [369]

Answer: 1) only a salt and water

An acid and base reacts together to undergo neutralization to form salt and water.

$HCl+NaOH\rightarrow NaCl+H_2O$

where HCl is an acid and NaOH is a base to form salt (NaCl) and water $(H_2O)$ .

Answer: 2) The formula of the hydrogen ion is often written as $H^+$ .

All acids dissociate in water to give $H^+$ ions.

Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.

$HCl\rightarrow H^++Cl^-$

Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.

$NaOH\rightarrow Na^++OH^-$

Answer: 4) A conjugate acid base pair transfers hydrogen ion.

$CH_3COO^-+H_2O\rightarrow CH_3COOH+H_3O^+$

Here $CH_3COO^-$ accepts a proton and thus act as a base and the corresponding $CH_3COOH$ is its conjugate acid.

Answer: 5) Bronsted Lowry acid is a substance that donates protons. Bronsted Lowry base is a substance that accepts protons.

$NH_4^+$ and $NH_3$

$NH_3+H^+\rightarrow NH_4^+$

$NH_3$ is a acid which accepts proton and thus acts as base to form conjugate acid $NH_4^+$ .

24 grams C convert to moles

Anon25 [30]

Answer:

Number of moles = 2 mol

Explanation:

Given data:

Mass of carbon = 24 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of carbon is 12 g/mol.

Now we will put the values in formula.

Number of moles = 24 g/ 12 g/mol

Number of moles = 2 mol

The reaction of equal molar amounts of benzene, C6H6, and chlorine, Cl2, carried out under special conditions, yields a gas and

WINSTONCH [101]

Answer : The molecular formula of a compound is, $C_6H_5Cl_1$

Solution : Given,

Mass of C = 64.03 g

Mass of H = 4.48 g

Mass of Cl = 31.49 g

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of Cl = 35.5 g/mole

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{64.03g}{12g/mole}=5.34moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{4.48g}{1g/mole}=4.48moles$

Moles of Cl = $\frac{\text{ given mass of Cl}}{\text{ molar mass of Cl}}= \frac{31.49g}{35.5g/mole}=0.887moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{5.34}{0.887}=6.02\approx 6$

For H = $\frac{4.48}{0.887}=5.05\approx 5$

For Cl = $\frac{0.887}{0.887}=1$

The ratio of C : H : Cl = 6 : 5 : 1

The mole ratio of the element is represented by subscripts in empirical formula.

The Empirical formula = $C_6H_5Cl_1$

The empirical formula weight = 6(12) + 5(1) + 1(35.5) = 112.5 gram/eq

Now we have to calculate the molecular formula of the compound.

Formula used :

$n=\frac{\text{Molecular formula}}{\text{Empirical formula weight}}$

$n=\frac{112.5}{112.5}=1$

Molecular formula = $(C_6H_5Cl_1)_n=(C_6H_5Cl_1)_1=C_6H_5Cl_1$

Therefore, the molecular of the compound is, $C_6H_5Cl_1$

Explain the law of conservation of energy. Give a specific example using kinetic and potential energy that shows how energy is c

Marrrta [24]

Answer:

The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This law is taught in physical science and physics classes in middle schools and high schools, and is used in those classes as well as in chemistry classes. When playing pool, the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.
