Answer:

Explanation:

Here, we are to copy and complete the paragraph with the correct options as given below in the question.

Before that, let us have an understanding of what a conversion factor is all about.

A conversion factor refers to a formula that is being used to change over an estimation in a given arrangement of units to its comparable estimation in another arrangement of units. Subsequently, the formula comprises both a number and its unit.

So;

\text{You can check that you have written the correct conversion factors for an }

\text{equality by looking at the numbers and units in each; the information on }

\text{one side of the equity appears in the of a conversion factor while the }

\text{information on the other side of the equity appears in the denominator.}

\text{To generate a second conversion factor, we "turn over" the first }

\text{conversion factor so the numbers and units in the numerator and }

\text{denominator switch places.}

A solid object has a mass of 1.62 lb and a volume of 190 mL.
Pachacha [2.7K]

The density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.

<h3>How to calculate density?</h3>

Density is the measure of the mass of matter contained by a unit volume. It can be calculated by dividing the mass of the substance by its volume.

According to this question, a solid object is said to have a mass of 1.62 lb and a volume of 190 mL.

1 pound = 453.592 grams

1.62 Ibs is equivalent to 734.82 grams

Density of the solid object = 734.82 grams ÷ 190 mL

Density = 3.87g/mL

Therefore, the density of a solid object that has a mass of 1.62 lb and a volume of 190 mL is 3.87g/mL.

Pick out the metals which can react with magnesium sulphate solution. Justify the answer.
KATRIN_1 [288]

Answer: aluminium, mercury , platinum and copper.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

XY+Z\rightarrow XZ+Y

Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.

The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.

Which statement best describes the variables in a controlled experiment?
RUDIKE [14]

The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.

<h3>What is an experiment?</h3>

An experiment is a scientific research, findings or investigation about a subject matter with the aim of validating a claim and establishing theories.

A controlled experiment refers to an experiment in which the variables involved and the control factor are kept in the same group except for one variable which can be changed.

Therefore, The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.
