It would be 23.46, since the next number is a 5 so we can round up.

Significant figures are:
ANY number that is not 0
Any 0 between two nonzero digits
Any 0 following a decimal (i.e 1.50)

Answer:

23.46

Explanation:

Significant figures are the number of digits or the numbers that contribute to the actual value of a measurement.

Some of the rules to check the number of significant figures are:

- All non-zero digits are always significant

-Zeros in between numbers are significant

-Leading zeros after decimal are not significant

-Trailing zeros after decimal are significant

-If the final digit after decimal is greater than or equal to 5, it can be rounded up to the next higher number

The given value is:

23.455 it has 5 significant figures

Rounding up (since the last digit = 5) to 4 significant figures gives:

23.46

Alkali

Explanation:

Fat and alkali are the two primary raw materials needed to manufacture soap.

Sodium hydroxide or potassium hydroxide is generally used as an alkali. The use of alkali depends on the intended application of the soap.

Raw animal fat was used in the past but these days, processed fat is used in the soap manufacturing process. Vegetable fats ( e.g, palm oil, olive oil, coconut oil) are also being used in soap manufacturing.

Additives are also used to enrich the color and texture of the soap.

The two molecules will only react if they have enough energy. By heating the mixture, you are raising the energy levels of the molecules involved in the reaction. Increasing temperature also means the molecules are moving around faster and will therefore "bump" into each other more often.
