At a pressure of 505 kPa, the volume of a gas is 12.00 mL. Assuming the temperature remains constant,
at what pressure will the new volume be 8.00 mL?

Answers

Answer:

757.5 kPa

Explanation:

Boyle's law states that p1 * v1 = p2 * v2

v1 = 12 mL

v2 = 8 mL

p1 = 505 kPA

p2 = ?

(505)(12) = (p2)(8)

6060 = (p2)(8)

p2 = 757.5

The volume of a sample of gas measured at 27 °C is 10.0 dm . What is the temperature when the volume is reduced to 9.0 dm at the same pressure?

Answers

The second temperature of the sample of gas is 24.3°C

The calculation can be done as follows

T1= 27 °c

T2= ?

V1= 10 dm

V2= 9 dm

V1/T1= V2/T2

10/27= 9/T2

Cross multiply

10 ×T2= 9 × 27

T2= 9 × 27/10

= 243/10

= 24.3 °C

Hence the second temperature is 24.3°C

Answers

The ratio of neutrons to protons (n/p) is a successful way in predicting nuclear stability. This ratio is close to 1 for atoms of elements with low atomic numbers (of less than about 20 protons). The n/p ratio steadily increases as the atomic number increases past element 20 (calcium) to about element 84 (polonium).

A and D would be correct

The property can be observed without changing the identity of the substance. The property can be observed or measured these are requirements for something to be a physical property.

What is physical properties ?

Physical properties are properties of matter that can be seen and studied without influencing a sample's molecular structure. The arrangement of the material in a sample may change when a physical quality is evaluated, but the molecules' patterns are unchanged.

Melting point ,boiling point are the example of physical properties.

A property of matter that is autonomous to a change in its chemical components is termed a physical property. Density, color, hardness, melting and boiling points, and electrical conductivity are very few common examples of physical features.

Thus, option A and D are correct.

The boiling point of water is 100.0*C, yet a student measured it to be 101.3*C. Calculate the percent error of the student's measurement.

Answers

Answer:

Percent error = 1.3%

Explanation:

Given data:

Actual value of boiling point = 100.0 °C

Measured value = 101.3 °C

Percent error = ?

Solution:

Formula:

Percent error = ( Measured value - Actual value / Actual value ) × 100

Now we will put the values in formula.

Percent error = 101.3 °C - 100.0 °C / 100.0 °C × 100

Percent error = 1.3 °C / 100.0 °C × 100

Percent error = 0.013 × 100

Percent error = 1.3%

Thus, percent error is 1.3.
