A package of chocolate instant pudding contains 2640 mg of sodium. how many grams of sodium are in the pudding?

Because they lack the stiffness required for alignment, molecules with only single bonds do not generally display liquid-crystalline characteristics. One or more atoms make up a molecule. The biological substances, such as proteins and DNA, can be composed of thousands of the atoms.

A molecule is composed of atoms that have been joined together. So, whereas an atom is a separate thing, a molecule is generated when those atoms come together. These elements are may be the same, such as the two oxygen atoms bonded together (O2), or they may be different atoms linked together, such as the water (H2O).

if ammonia is fed to a continuous reactor at a rate of 100.0 kmol nh3/h

175 Kmol/h is oxygen the fed rate that corresponds to 40% excess O₂.

Given chemical reaction is

4NH₃ + 5O₂ → 4NO + 6H₂O

The molecular weight of NH₃ is 17.03, O₂ is 32, NO is 30, and, H₂O  is 18.

To find the ratio,

Ratio = lb-mole O₂ react / lb-mole NO formed

Or, ratio = 5/4

Or, ratio = 1.25

NH₃ fed rate = 100 Kmol/h

We have to find out whether the Oxygen fed rate corresponds to 40% excess O₂.

For each 4 Kmol of NH₃, 5 Kmol of O₂ is required.

4 Kmol of NH₃ ≡ 5 Kmol of O₂

100 Kmol of NH₃ ≡ 125 Kmol of O₂

So, 125 Kmol of O₂  is required for 100 Kmol of NH₃.

For 40% excess of O₂, the required Kmol is = 125 + 125 × 40%

The required Kmol of oxygen is 175 Kmol/h for excess of O₂.

The molarity of a solution of KIO3 is dissolved in enough water to make 250.0 ml of solution is 0.1595.

Molarity is the measure of the concentration of any solute per unit volume of the solution.

M = {n}{V}

The molar mass of KIO3 is  214.001

Given the mass is 853.5 mg

First, we calculate the number of moles

moles = mass / molar mass

853.5 / 214.001 = 3.988

Now, molarity can be calculated

The number of moles is 3.988

The volume is 250.0 ml

Putting the values in the formula

M =  3.988  / 250.0 = 0.1595

Thus, the molarity is 0.1595.

1 mol of NaOH = 1 mol of NaCl

Therefore, 0.5mol of NaOH = 0.5mol of NaCl

0.5mol = Mass of NaCl / (23 + 35.5)

Combustion is defined as the process of burning something. In chemistry, combustion refers to the chemical process between a fuel and an oxidant, usually oxygen to produce heat and light in the form of flame.

In a complete combustion, oxygen is sufficient to react with any hydrocarbons to produce carbon dioxide and water.
