Calculate the number of formula units in 1.87 mol of NH4Cl
nydimaria [60]

Answer:

1.13 x 10²⁴formula units

Explanation:

Given parameters:

Number of moles of NH₄Cl = 1.87mol

Unknown:

Number of formula units = ?

Solution:

From mole concept;

     1 mole of a substance contains 6.02 x 10²³ formula units

Now;

    1.87 moles of  NH₄Cl   1.87 x 6.02 x 10²³ = 1.13 x 10²⁴formula units

Answer:

Always equal to the total moles of the products.

Explanation:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction equal to the mass of the reactants.

Based on the passage, what is the structure of the product of the reaction between 8-hydroxyquinoline-5 sulfonate and HRP mcat r
dusya [7]

A because the outcome of this reaction exists a radical formed by the oxidation of an aromatic amine's or phenol's ring substituent. The hydroxyl group of a phenol serves as the ring substituent in this condition.

<h3>Which two enzyme types are required for the two-step process of converting cytosine to 5 hmC?</h3>
  • The methyl group exists moved to cytosine in the first step, and it exists then hydroxylated in the second stage.
  • Thus, a transferase and an oxidoreductase exist as the two groups of enzymes needed.

<h3>Which kind of interaction between proteins and the dextran column material is most likely to take place?</h3>
  • Hydrogen bonding because the glucose's OH would create an H-bond with any disclosed polar side chains on a protein surface.

<h3>Two out of the four proteins would adhere to a cation-exchange column at what buffer pH?</h3>
  • Only positively charged proteins can attach to a cation-exchange column, and this can only occur when the pH exists lower than the pI.
  • Proteins A and B would both be positively charged at pH 7.0.

What type of fuel does a nuclear power plant use to generate steam
AlekseyPX
They use Uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission. Nuclear power plants obtain the heat needed to produce steam through a physical process. This process, called fission, entails the splitting of atoms of uranium in a nuclear reactor.

Hope this helps! :)
