Answer:

D.) The original components retain their individual properties

Explanation:

A pure substance is a substance of constant chemical composition throughout its mass some of the examples of the pure substances are iron, water, oxygen gas, nitrogen gas etc.

A pure substance can in the form of solid, liquid or gas which have constant property. Two or more pure substances combines together to from a mixture after which is not said to be pure substance

For example the one or more atom of the same element is said to be pure but the molecule of two different elements is not said to be a pure substance as they have different property of both of the elements like H2 and H2O where H2 is a pure substance and H2O is not a pure substance.

The pure shows their individual property if they are not combined with other elements or substance as it will not posses individual property.

A sample of helium gas initially at 37.0°C, 785 torr and 2.00 L was heated to 58.0°C while the volume expanded to 3.24 L. What i
spayn [35]

Answer:

0.681 atm

Explanation:

To solve this problem, we make use of the General gas equation.

Given:

P1 = 785 torr

V1 = 2L

T1 = 37= 37 + 273.15 = 310.15K

P2 = ?

V2 = 3.24L

T2 = 58 = 58+273.15 = 331.15K

P1V1/T1 = P2V2/T2

Now, making P2 the subject of the formula,

P2 = P1V1T2/T1V2

P2 = [785 * 2 * 331.15]/[310.15 * 3.24]

P2 = 515.715 Torr

We convert this to atm: 1 torr = 0.00132 atm

515.715 Torr = 515.715 * 0.00132 = 0.681 atm

m_a_m_a [10]

Answer:

0.05263158 atm

Explanation: mmHg to Atmosphere Conversion Example. Task: Convert 975 mmHg to atmospheres (show work) Formula: mmHg ÷ 760 = atm Calculations: 975 mmHg ÷ 760 = 1.28289474 atm Result: 975 mmHg is equal to 1.28289474 atm. This is an example for how i got the answer.
