The answer is 0.10 M NaOH. The NaCl is neutral. The HCl is acid. NaOH and NaNO2 are base. The base has higher pH than acid. The NaNO2 is weak base while NaOH is strong base. So the NaOH has higher pH than NaNO2.

1. 2KCIO3, -- 2KCI + 302<br> How many moles of O2 will be produced from 2.25 moles of KCIO3?
Scilla [17]

Answer:

3.375moles of O₂

Explanation:

The reaction expression is given as;

                   2KClO₃ → 2KCl + 3O₂

Number of moles of KClO₃  = 2.25moles

Now;

To find the number of moles of O₂ produced we use known number of moles.

So;

                  2 mole of KClO₃ will produce 3 moles of O₂

                 2.25moles of KClO₃ will produce \frac{2.25 x 3}{2}   = 3.375moles of O₂

PH
Orlov [11]

Explanation:

A chemical property is defined as the property that brings changes in chemical composition of a substance.

For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.

On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.

For example, shape, size, mass, density etc are all physical properties.

Thus, we can conclude that these may all be classified as chemical properties of a substance.
