Using the density, the mass of sulfuric acid is 2292.82 grams.

We need to know about the density to solve this problem. Density is a unit that measures how dense an object is. Density can be measured by dividing mass by volume. It can be written as

ρ = m / V

where ρ is density, m is mass and V is volume

From the question above, we know that

ρ = 1.31 g/mL

V = 1 gallon = 4546.09 mL

% sulfuric acid = 38.5%

By substituting the following parameters, we get total mass

ρ = m / V

m = ρ .V

m = 1.31 . 4546.09

m = 5955.38 grams

Find the sulfuric acid mass

ms = %sulfuric acid x m

ms = 38.5% x 5955.38

ms = 2292.82 grams

When solid chromium(III) oxide reacts with liquid aluminium to give liquid chromium and liquid aluminium oxide at high temperature, the balanced chemical equation of the reaction including the states of matter can be written as :

                    Cr₂O₃(s) + 2Al(l)    →   2Cr(l) + Al₂O₃(l)

This reaction occurs at high temperature because the reactivity is increased under this condition.The liquid aluminium is oxidized to form liquid aluminum oxide and the solid chromium(III) oxide is reduced to form liquid chromium.

Chromium(III) oxide is amphoteric in nature and insoluble in water. If it is reacted with aluminium, it gets reduced to the chromium metal. It is a type of simple replacement reaction as Chromium metal is replaced by the aluminium. It is an example of displacement reaction.

Option a. The maximum oxygen uptake is known as the VO2 max.

This means that the maximum amount of oxygen that one's body can take during the exercise is VO2 max.

An exercise is an aerobic activity that requires oxygen more than normal activities due to a lot of physical effort.

When people exercise, their breathe heavily because the body needs more oxygen.

During this process, the ATP empowers the cells to release CO2 that produces during the respiratory process when we exhale.

So the greater the VO2 max is, more will be the benefits. As the body can consume more oxygen, the maximum amount of ATP energy is generated.

Answer: USA is on the North plate American!

Explanation:

The bond that exists between two oxygen atoms to make the O2 molecule is described as two covalent bonds and two lone pairs of electrons are present on each individual oxygen atom.

A double bond in chemistry is a covalent bond between two atoms that involves four bonding electrons, rather than two as in a single bond.

In the oxygen molecule, O2, the oxygen atoms that make up the molecule are bonded together by sharing two pairs of electrons. Each oxygen atom has 6 valence electrons, if they share two of their valence electrons with each other, they each have 8 valence electrons.

In this way, the so-called octet rule is fulfilled, where atoms gain, lose or share electrons with other atoms to have 8 valence electrons and thus acquire a noble gas configuration.

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons

We know that the equilibrium constant is a value that shows us the position to which the equilibrium position would switch when a constraint is imposed. We know that the imposition of a constraint would cause the equilibrium position to shift to the left or to the right in such a way that seeks to annul the change that is causing it.

We know that if a product is added, the equilibrium position would shift to the left and more reactants are produced. On the other hand, if a reactant is added, the equilibrium position would shift to the right and more products are added.

Having said this;

If we add the H3O^+ ion, then the equilibrium would shift to the left and if it is removed the equilibrium would shift to the right.

The molar mass of camphor is 152 g/mol.

We have given that,

P = 12 torr or 0.01579 atm

1 atm = 760 torr

Density = 0.0829 g/l

R = 0.0821 L.atm/mol.K

And temperature is

T = 273° K + 80° K

  = 353° K

As we all know,

PV = nRT

so, PV = mass × R × T / molar mass

also, P = mass × R × T / volume × molar mass

here, mass/ volume = density (d)

P = dRT / molar mass

Now putting the values and simplify,

0.01579 = 0.0829 × 0.0821 × 353 / molar mass

molar mass = 152.156 g/mol.

thus, the molar mass of camphor is 152 g/mol.

The molar mass of a chemical substance is determined in chemistry by dividing the amount of a substance with that compound by the quantity of that compound, which is the number of moles in exactly that sample, which is measured or calculated in moles.

In contrast to molecular properties, a substance's molar mass is a bulk property. The compound is present in many different forms, each with a different mass as a result of the isotopes. The molar mass is the average of these masses.

The molar mass is often calculated using the standard atomic weights and is therefore an average for Earth and a function of the relative abundance of the constituent atoms' isotopes.
