Assuming the compound is dissolved in water,what is the formula for phosphorus acid?

marishachu [46]

The answer is H3PO3.

The formula for phosphorus acid would be H3PO3 assuming that this compound is dissolved in water. <span>This acid is diprotic, not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.</span>

You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?

givi [52]

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃ + Cu → Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

If we see stoichiometry, ratio is 1:2

How many atoms are in KCI

vovikov84 [41]

<h3>Answer:</h3>

2 atoms

<h3>Explanation:</h3>

Compounds are substances that are formed when two or more elements chemically combine.
They are made up of molecules that contain different atoms from different elements.
For example, KCl is a compound that is made up of two atoms, one potassium atom and one chloride atom.

Unlike elements that are made of similar atoms, compounds contains atoms that are not similar from different elements.

How could you demonstrate boiling point?

EleoNora [17]

A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
