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

Methane, ch4, is the gas commonly found in labs to fuel bunsen burners. A) how many moles of methane are there in a 7. 21 gram sample?
Using the molar mass of methane, there are 0.45 mole of methane in a 7.21 gram sample.
Molar mass is defined as the mass per unit mole of a substance.
MM = m/n
where MM = molar mass
m = mass
n = number of moles
The molar mass of methane is the sum of the molar masses of each element.
C : 12.011
H : 1.00784
CH4 : 12.011 + 4(1.00784) = 16.04236 g/mol
If a sample of methane has a mass of 7.21 grams, using the formula for the molar mass, solve for the number of moles.
MM = m/n
16.04236 g/mol = 7.21 g/n

Distinguish between haploid and diploid
When an organism's cells only have one set of chromosomes, the organism is said to be haploid. All organisms that reproduce sexually are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.
The term "diploid" describes an organism's cells having two full sets of chromosomes, with one chromosome from each parent present in each pair. Since humans are diploid, the majority of their cells have 23 pairs of chromosomes.
Distinguish between haploid and diploid.
The number of chromosome sets found in the nucleus is the most obvious distinction between haploid and diploid cells. In contrast to diploid cells, which have two sets of chromosomes, haploid cells only have one set.The result of mitotic cell division is the formation of diploid cells. Following meiotic cell division, haploid cells are produced.Since there are two sets of chromosomes, there are two times as many chromosomes overall as there are in haploid cells. In comparison to diploid cells, there are half as many chromosomes because there is only one set present.To know more about haploid and diploid, click on the link below:

an atom is in its lowest energy state, or state, when its electrons are in the lowest possible energy levels. if an electron moves to a higher energy state the atom is said to be in a(n) state.
An atom's ground state is its lowest energy conceivable state, in which all of its electrons are at their lowest possible energy levels.
What degree of energy does an atom contain?The energy levels of the atoms match the rows of the Periodic List of Elements when you look at it. The last electrons of the two elements on the top row, hydrogen and helium, are filling their initial energy level.
The second energy level of the eight components in the second row is being filled. The chemical characteristics of an element are determined by its outermost electrons.
Starting with the level nearest to the nucleus, the energy levels were built up. By using the Aufbau Principle, electrons are filled in by moving from the initial lowest-energy level to a second, slightly higher energy level, and finally to the third, even higher energy level.

1 mol 1 mol
mol of NaI₃ = 34.60 mL × 1 L / 1000 mL × 0.5560 mol / L
= 19.2376 × 10⁻³ mol
∵ 1 mol of Sn²⁺ = 1 mol of I₃⁻
∴ mol of Sn²⁺ = 19.2376 × 10⁻³
∴ mass of Sn in sample = mol of Sn²⁺ × molar mass
= ( 19.2376 × 10⁻³ mol ) × 118.71 gm/mol

When purified cytochrome oxidase is exposed to cyanide, the cyanide binds reversibly and with high affinity to the enzyme’s active site. What will be the likely outcome if mitochondria are exposed to high levels of cyanide?.
The likely outcome if mitochondria are exposed to high levels of cyanide will be that the cyanide will prevent movement of electrons along the electron transport chain.
The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).
More than 90% of the energy in your body's cells is produced by mitochondria, which act as batteries in the cells. In high-energy-demanding organs including your heart, liver, muscles, and brain, mitochondria play a critical role. Mitochondria make about 25% of liver cells and 40% of heart muscle cells, respectively.
