Why is NCl3 not soluble in water?

Answers

Answer:

Explanation:

NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

Answer:

A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".

Record the mass of the object based on the reading from the triple-beam balance. The mass of the object is ____ grams.

Answers

Hello!

[tex]\large\boxed{167g}[/tex]

Looking at the balance, we see that:

The middle beam reads 100g.

The top beam reads 60g.

The bottom beam reads 7g.

Add all of the numbers together to get the total mass:

100 + 60 + 7 = 167g.

The mass of the object is 167 grams.

Explanation:

A triple beam balance is a mass measuring instrument used in labs to measure the mass of a substance. It unit in which it measures is grams. It consists of three beams which are: The middle beam has  Increments of 100 grams  The front beam has  Increments from 0 grams  to 10 grams  The farther beam has  Increments of 10 grams

Given :

Readings of all the scales of three beams of the triple beam balance of an object.

To find :

The mass of object whose reading on triple beam balance is given.

Solution:

Middle beam reader at 100 grams

Front beam reader at 7 grams

Farther beam reader at 60 grams

The mass of object:

[tex]100 grams + 7 garms + 60 grams = 167 grams[/tex]

The mass of the object is 167 grams.

if the atomic mass is 14 and the atomic number is 7,how many neutrons do you have?​

Answers

Answer: 7 neutrons

Explanation: Atomic number refers to the number of protons in the nucleus of the atom. Also you can treat atomic mass as how many particles (protons and neutrons) are in the nucleus of the atom. So for this problem:

14 particles - 7 protons = 7 neutrons (and we know all that's left over is neutrons because we subtracted all the protons)

______elements that have a longer half-life are more _______ than those that have a shorter half-life.

Answers

Answer:

Radioactive elements

Stable

Explanation:

Radioactive elements that have a longer half-life are more stable than those that a shorter half-life.

Half-life is the time taken for half of a radioactive element to decay by half of its original composition.

Now, if a substance have a long half-life, it is more stable and takes time to break down. For atoms with a short life, they are highly unstable and breaks down readily and easily.

Answers

Answer:

[OH⁻] = 8.91x10⁻¹²M

Explanation:

In aqueous solutions, the [OH] and [H⁺] are associated in the equation of hydrolisis of water:

1x10⁻¹⁴ = [OH⁻] [H⁺]

With pH, we can solve for [H⁺] and obtain, the [OH⁻] using this equation:

pH = -log [H⁺]

[H⁺]= 10^-pH

[H⁺] = 1.122x10⁻³M

1x10⁻¹⁴ = [OH⁻] [1.122x10⁻³M]

1. What part of the human body has the same role as the power source in a computer?

2.What part of the human body has the same role as the keyboard or the mouse on a computer?

Answers

Answer:

The heart

Hand

Explanation:

The part of the human body that has the same role as the power source in a computer is the heart. A power source in a computer provides energy that powers the whole system.

The human heart provides the pumping action for the circulatory system. Just like current passes through wires in a computer by energy from the power source, the human heart pumps blood throughout the body in a like manner. Without the pumping action of the heart, the human body is dead.

Also, keyboard and mouse are input devices. They are used to give instruction and perform certain tasks on the computer system.

The human body can also carryout tasks by using the hand. Objects are moved from one place to another just as you drag an icon using the mouse. We type word processors using information from the keyboard, also, we are able write using pen on paper.

Explanation:

In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.

Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.

Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.

In genetics, there are: Substitution, Insertion and Deletion mutations.

Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.

Answer:

A. Substitution

B. Insertion

C. Deletion
