What is dimensional analysis of formulas?

By looking at the units of the quantities involved, dimensional analysis is a technique for determining whether a physical equation or formula is right. The essential tenet of dimensional analysis is that the quantities being multiplied or divided in the equation must have units that are equal to the units of the final result.

We know that we have to apply the principles that apply to dimensional analysis in the question and we have that;

m^2.s/m.s^2

= ms-1

HELP ASAP!! An experiment is performed in which a crystalline substance is added to a beaker filled with room-temperature water. The following observations were made:
1. The crystals dissolve.
2. A precipitate forms.
3. The bottom of the beaker feels warm to the touch.
4. Bubbles begin to form in the water.
Which observations are evidence that a chemical reaction took place?

Answers

Answer:

observations (2), (3), and (4) provide strong evidence that a chemical reaction occurred.

Explanation:

Observations (2), (3), and (4) are evidence of a chemical reaction because a precipitate formed, energy was released (the bottom of the beaker felt warm), and bubbles were formed in the water. Observation (1) indicates a physical change, not a chemical reaction.

observations 2, 3, and 4 indicate that a chemical reaction has occurred.

3) The exponent is 10^-9

4) The exponent is 10^-1

What is the missing prefix?

A number is written in scientific notation as the product of a decimal number between 1 and 10 with a power of 10. The size of the number being represented is indicated by the prefix used for powers of 10.

These prefixes can be used to express very large or very small numbers in a compact and convenient way. We can see that the representation that we have above would be used as a kind of a shorthand notation in science.

When we simplify the measurement, 7.9 m²s/ms², the result obtained is 7.9 m/s

How do i express the measurement in it's simplest form?

The following data were obtained from the question:

Measurement = 7.9 m²s/ms²Simplest form =?

The measurement, 7.9 m²s/ms² can be expressed as follow:

7.9 m²s/ms²

Cancel out the letters where necessary

7.9 m/s

We can proceed further by expressing in standard form. This is written as

79×10⁻¹ m/s

Now considering the two expression of the measurement obtained above, we can see that 7.9 m/s is far simpler than 79×10⁻¹ m/s

Thus, we can conclude that the simpler form of 7.9 m²s/ms² is 7.9 m/s
