Answer:

extensive properties such as mass and volume depend on something like perhaps the amount of what's measured. physical properties can be measured without changing substance chemical identity.

metals are the elements which exhibit degree of metallic behavior is know as metals. non metals are such elements which do not posses any metallic behavior and mekkloids are those elements that posses some of the properties like metal. but they act either like metals or non metals n they also have the same physical properties

If 24.1 g of sodium hydroxide react with 22.0 g of hydrochloric acid to form 35.3g

disa [49]

Answer:

10.85 g of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

NaOH + HCl —> NaCl + H2O

Next, we shall determine the mass of NaOH that reacted and the mass of H2O produced from the balanced equation.

These can be obtained as illustrated below:

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol

Mass of NaOH from the balanced equation = 1 × 40 = 40 g

Molar mass of H2O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mass of H2O from the balanced equation = 1 × 18 = 18 g

Summary:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Finally, we shall determine the mass of water, H2O produced from the reaction as follow:

From the balanced equation above,

40 g of NaOH reacted to produce 18 g of H2O.

Therefore, 24.1 g of NaOH will react to produce = (24.1 × 18)/40 = 10.85 g of H2O.

Therefore, 10.85 g of H2O were produced from the reaction.

AveGali [126]

Answer:

I do not agree with using pesticides as it is a chemical and can inflict poison in the system. A better alternative would be using smoke to keep the pests away or some natural pesticide. The effect would most likely be lower quantities of crops and higher food prices however.
