Answer:

A compound is the substances that are formed by combining two are more chemical elements. A mixture is a substance created from two or more matter that can be separate with the help of physical methods. Compound substances are always homogeneous in nature.

Composition: The ratio of the elements in compounds is always fixed. They contain o...

A certain gas is present in a 13.0 L cylinder at 1.0 atm pressure. If the pressure is increased to 2.0 atm , the volume of the g

Scorpion4ik [409]

<h3>Answer:</h3>

The gas obeys the Boyle's law

<h3>Explanation:</h3>

According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at constant absolute temperature.
That is; $P\alpha\frac{1}{V}$
Therefore, $k=PV$ , where k is a constant
At varying volume and pressures while keeping absolute temperature constant; k = P1V1 =P2V2

In this case, we are given;

Initial Volume of 13.0 L at initial pressure of 1.0 atm

New volume of 6.5 L at new pressure of 2.0 atm

But, K = PV

Therefore,

k1 = P1V1

= 1.0 atm × 13.0 L

= 13 atm.L

k2 = P2V2

= 2.0 atm × 6.5 L

= 13 atm.L

Thus, k1=k2

Thus, the gas obeys the Boyle's law

An isotope contains 47 protons, 47 electrons, and 60 neutrons. What is the identity ok the isotope.

Gekata [30.6K]

Answer is: the identity of the isotope is silver (Ag-107).

p⁺(isotope) = 47; number of protons in isotope.

Z = p⁺; atomic number.

Atomic number is the number of protons, which is characteristic of a chemical element, silver is an element with atomic number 47.

n°(isotope) = 60; number of neutrons in isotope.

A = p⁺ + n°; mass number is the total number of protons and neutrons in a nucleus.

A = 47 + 60.

A = 107.
