Conclusions related to historical events are limited to subjective evaluation of the existing evidence because _____. they cannot be repeated they don't need to be tested hypotheses cannot be developed that is good enough

Answers

This is not actually a chemistry question but okay:

Conclusions related to historical events are limited to subjective evaluation of the existing evidence because 
they cannot be repeated. 

Answer:

they cannot be repeated

Explanation:

A historical event can not be repeated so that it is possible to study it. For this reason, when studying a historical event it is necessary to search for documents that speak about that event in a consensual way. For this reason, we can see that the conclusions related to historical events are limited to the subjective evaluation that will vary according to the judgment of each person.

Convert 2.70
atm
to
torr

Answers

To convert atm to torr, we should know 1 atm equals 760 torrs then the conversion exists 2052 torr.

What is meant by pressure conversion?

Torr and atmare the two main pressure units. To convert atm to torr, we should know 1 atm equals 760 torrs.

It exists the manometric pressure unit. It exists described as, the pressure exerted by column of mercury one millimeter high it exists represented by mmHg.

Torr to mmHg conversion:

Both exists equivalent to each other.

1 torr = 1 mmHg

Torr to atm:

Torr exists converted into atm by dividing the torr value 760.

mmHg to atm.

mmHg exists converted into atm by dividing the torr value 760.

Kilopascal:

The kilopascal exists the unit of pressure. It exists denoted by KPa.

Given:

2.70 atm

The conversion exists given by,

1 atm = 760 torr

2.70 atm = 760 × 2.70 torr

= 2052 torr

Therefore, the correct answer is 2052 torr.

What is the volume of solution (in mL) produced when 91.80g of Mg(OH)2 are usedto produce a 0.7M solution? Record your answer to 1 decimal places.

Answers

Answer:  The volume of solution is 2248 ml

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=(n* 1000)/(V_s)

where,

n = moles of solute

V_s = volume of solution in ml

moles of Mg(OH)_2 = \frac{\text {given mass}}{\text {Molar mass}}=(91.80g)/(58.32g/mol)=1.574mol

Now put all the given values in the formula of molality, we get

0.7=(1.574* 1000)/(V_s)

V_s=(1.574* 1000)/(0.7)=2248ml

Therefore, the volume of solution is 2248 ml
