Molar concentration of barium cations in solution of3 .62g of barium nitrate is dissolved in 350. mL of a 71.0mM aqueous solution of sodium chromate is 0.039M
Molar concetration of barium cation can be calculate as follows:
first we should make balanced equation
Ba(NO₃)₂(aq) + Na₂CrO₄(aq) → BaCrO₄(s) + 2NaNO₃(aq)
while,
Mass of barium nitrate = 3.62 grams
Volume of 0.071 M sodium chromate 350 mL
Then we can calculate the number of moles of Ba(NO₃)₂
mole = mass / molar mass
Moles = 3.62 grams / 261.34 grams/mole
Moles = 0.0138 Moles
Then, calculate the number of moles of Na₂CrO₄
moles = molarity * volume
moles Na2CrO4 = 0.071 * 0.35 liters
mol Na2CrO4 = 0.0248 mol
so, we can calculate limiting reactants
Since Na₂CrO₄ is in excess, all Ba(NO₃)₂ is consumed and reacts to BaCrO₄ in the form of Ba²⁺.
then we can calculate the number of moles of Ba²⁺
nBa²⁺=n(BaCrO₄) =n(Ba(NO₃)₂) = 0.0138 Moles
then calculate Ba²⁺ Molarity

Considering the Boyle's law, if the temperature does not change, the new volume will be 6.25 L.
Boyle's lawThe gas laws are a set of chemical and physical laws that allow determining the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.
Boyle's law is one of the gas laws that relates the volume and pressure of a certain quantity of gas kept at constant temperature.
This law states that the pressure of a gas in a closed container is inversely proportional to the volume of the containert. That is, if the pressure increases, the volume decreases; while if the pressure decreases, the volume increases.
Mathematically, Boyle's law states that the product of pressure and volume is constant:
P×V= k
where P is the pressure and V the volume, being k a constant.
Studying two different states, an initial state 1 and a final state 2, it is satisfied:

Efficiency variance is defined as the discrepancy between the actual number of inputs used and the theoretical number of inputs needed to produce a unit of output. Based on models or prior experiences, the expected inputs to generate the unit of output are predicted.
Thus, the difference between the actual level of activity and the standard activity allowed for the actual output x the variable part of the predetermined overhead rate is the variable overhead efficiency variance.

Eukaryotic DNA is located in the nucleus and its message reaches the ribosome by passing through the nuclear pore.
What is meant by eukaryotic DNA ?Eukaryotic DNA has telomeres at each end to prevent degradation and is linear, compacted into chromosomes by histones. Circular DNA and smaller, transferrable DNA plasmids are both found in prokaryotes. Nuclear DNA and mitochondrial DNA are both present in eukaryotic cells.
Eukaryote refers to any cell or organism with a separate nucleus. A nuclear membrane encircles the nucleus of a eukaryotic cell, which contains the distinct chromosomes (bodies that hold the genetic material).
Each chromosome's DNA molecule, which has the shape of a double helix, is first wound around histone protein clusters. The smallest unit of DNA packing structure is a nucleosome, which is made up of about 200 base pairs of DNA wrapped around eight histone proteins.

Given a reaction between an organic molecule, denoted as a, and nash, we observe the following observations. Using the observations, write a rate law for the reaction.
When [A] concentration is lowered in half and [NaSH] concentration is quadrupled, the rate doubles.
What is molecule and example?The simplest unit of any substance consisting of one or more components that may exist on its own while having each of the material's physical and chemical characteristics is called a molecule. In molecules, more atom division takes place. For instance, the atom and molecule of oxygen are represented by the letters O & O2, respectively.
What is a molecule or atom?Particles are referred to as the "basic building units of matter." The smallest building blocks of a substance are the qualities of the chemical element. Covalent (chemical) bonds hold one or more atoms together to form molecules.
