chlorine is an active non metal​

Answers

Chlorine in group 17 in the periodic table and includes halogens (also fluorine, bromine, and iodine)

Electron configuration of Cl : [Ne] 3s² 3p⁵

From this configuration, it can be seen that to obtain stability like the noble gas Ar - [Ne] 3s² 3p⁶, Chlorine will need one more electron so that its configuration is the same as Ar( become anion-Cl⁻)

Then it is said that Cl is reactive

And the Cl element is included in the non-metal group because it attracts electrons (electronegative)

The elements that include non-metals are halogens, noble gases, and 7 elements H, C, N, O, P, S, Se.

The half-life of tritium (H-3) is 12.3 years. If 48.0mg of tritium is released from a nuclear power plant during the course of a mishap, what mass of the nuclide will remain after 49.2 years?

Answers

Answer:

The amount left after 49.2 years is 3mg.

Explanation:

Given data:

Half life of tritium = 12.3 years

Total mass pf tritium = 48.0 mg

Mass remain after 49.2 years = ?

Solution:

First of all we will calculate the number of half lives.

Number of half lives = T elapsed/ half life

Number of half lives =  49.2 years /12.3 years

Number of half lives =  4

Now we will calculate the amount left after 49.2 years.

At time zero 48.0 mg

At first half life = 48.0mg/2 = 24 mg

At second half life = 24mg/2 = 12 mg

At 3rd half life = 12 mg/2 = 6 mg

At 4th half life =  6mg/2 = 3mg

The amount left after 49.2 years is 3mg.

45.0 g of CaCl, are dissolved in enough water so that the molarity of the solution is 1.15 M. What is the volume in mL of the solution?

Answers

CaCl calculate the molar mass of the compound first so u will get M.M=75.5 mol/g
Now multiple the mass of the compound by the molar mass ( make sure to cancel the mass unit so u get mole at the end)
45.0g x ( 1 mole:m/75.5g)
= 0.5960 mole
Now calculate the V
C= n/ V
V= n/c = 0.5960mole / 1.15 mol/ L = 0.6854 L
You are not done yet it asks for ml so multiple by 1000

Why is the force of gravity greater for an object orbiting Earth than for the
same object orbiting Pluto?
A. Earth has only one moon, while Pluto has three.
B. Earth is closer to the sun than Pluto.
C. Earth has a heavy atmosphere and Pluto does not.
D. Earth is more massive than Pluto.

Answers

Answer:

d) Earth is more massive than Pluto.

Explanation:

The force of gravity is greater for an object orbiting the Earth than for the same object orbiting Pluto, because Earth is more massive than Pluto.

The common factor is that the greater the planet's mass, the greater its gravitational force acting on an object. Hence, the option (d) is the correct answer.

What do these two changes have in common?
water evaporating from a lake
sediment settling to the bottom of a muddy puddle
Select all that apply.
Both are only physical changes.
Both are chemical changes.
Both are caused by heating.
Both are caused by cooling.

Answers

Answer:

Both are caused by heating. Both are Chemical changes.

Explanation:

Water evaporates from the Sun's heat and is transformed into a gas.

Sediment is the particles of an object. When heat hits it, it starts breaking up, or in dry cases, heating and cracking.

The study of chemicals is called chemistry.

The correct answer is B.

There are two types of changes in the chemical reaction. These changes are as follows:-

Physical changeChemical change.

The change which is reversible is called a physical change. For example - evaporating of water.

The change which is irreversible and can not get back to is original form is called chemical change. For example - the digestion process in a human.

According to the change, the correct answer is A that is a physical change because both can change back to their original form.

Hence, the correct answer is A.
