What is 19 degrees Celsius in Fahrenheit?

Answers

Answer 1

Answer: ºF = ºC x 1.8 + 32

ºF = 19 x 1.8 + 32

ºF = 34.2 + 32

= 66.2ºF

hope this helps!

Current atomic models show that atoms do not have positively-charged particles. B. Current atomic models show an atom's positively-charged particles concentrated in the center of the atom. C. Current atomic models show that atoms do not have negatively-charged particles.

If 4.00 g of NaCl react with 10.00 g of AgNO3, what is the excess reactant?

Answers

Answer : The excess reagent is, $NaCl$

Explanation :

First we have to calculate the moles of $NaCl$ and $AgNO_3$ .

$\text{Moles of }NaCl=\frac{\text{Mass of }NaCl}{\text{Molar mass of }NaCl}=(4g)/(58.4g/mole)=0.068moles$

$\text{Moles of }AgNO_3=\frac{\text{Mass of }AgNO_3}{\text{Molar mass of }AgNO_3}=(10g)/(169.9g/mole)=0.058moles$

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$NaCl+AgNO_3\rightarrow AgCl+NaNO_3$

From the balanced reaction we conclude that

As, 1 mole of $NaCl$ react with 1 mole of $AgNO_3$

So, 0.068 moles of $NaCl$ react with 0.068 moles of $AgNO_3$

From this we conclude that, the moles of $AgNO_3$ are less than the NaCl. So, $AgNO_3$ is a limiting reagent because it limits the formation of products and $NaCl$ is an excess reagent.

Hence, the excess reagent is, $NaCl$

The reaction formula of this is NaCl + AgNO3 = NaNO3 + AgCl. The mole number of NaCl is 4/58.5=0.068 mol. The mole number of AgNO3 is 10/170=0.059 mol. So the NaCl is excess.

A similarity between the forces involved in both ionic and covalent bondingis that bothO A) involve the sharing of electrons.O B) involve the transfer of electrons.O C) involve the attraction of opposite charges.requre same amountof energy toereakther bonds

Answers

Stating the difference between covalent and ionic bonding....

ionic bonds consist of the transfer of electrons, and covalent consists of the sharing of electrons.

This being said..answer choices A and B are out of the picture.

Thus, answer choice C is your answer.

Involve the attraction of opposite charges;require same amount of energy to break their bonds.

The valence electrons in an atom of phosphorusin the ground state are all found in
(1) the first shell
(2) the second shell
(3) the third shell
(4) the fourth shell

Answers

The valence electrons in an atom of phosphorus in the ground state are all found in IN THE THIRD SHELL.

Phosphorus has an atomic number of 15, therefore its electronic configuration is 2, 8, 5. This configuration implies that, phosphorus electrons are distributed in three different shells and the number of electrons in the outermost shell, which is the third shell, is 5. The ground state refers to a state, where the atoms of phosphorus are not excited. Electrons move away from their ground states when they are excited.

Which sample is a homogeneous mixture?A) NaCI(s)
B) NaCl(aq)
C) NaCl(g)
D) NaCl(ℓ)

Answers

NaCl(aq) is a homogeneous mixture. Hence, option B is correct.

What is a mixture?

A mixture is a substance that is made up of two or more substances that are not chemically combined and in fixed proportions.

Homogeneous mixtures are present with a similar uniform appearance and composition throughout. Examples are steel, air, salt water, etc.

Homogeneous mixtures may either be, a colloid or a solution.

An aqueous sodium chloride is a homogeneous mixture because NaCl completely dissolves in water, thus giving a single visible phase.

Hence, option B is correct.

NaCl(aq) is a homogeneous mixture.

An aqueous sodium chloride is a homogeneous mixture because NaCl completely dissolves in water, thus giving a single visible phase.

Further Explanation

Mixture

A mixture is a substance that is made up of two or more substances that are not chemically combined and in fixed proportions.
A mixture may have several varying physical properties.
There are two types of mixture:

Homogeneous mixtures

These are mixtures with a similar uniform appearance and composition throughout. Examples are, steel, air, salt water, etc.
Homogeneous mixtures may either be, a colloid or a solution.

Solutions

Solutions are types of homogeneous mixtures containing two or more substances in a single phase.
Solutions contains, a solute which is the substance that dissolves in the other substance, and a solvent which is the substances that dissolves the solute.
For example, in a salt solution, water is the solvent and salt is the solute.

Colloid

A colloid is a homogeneous solution that has an intermediate size particles between a suspension and a solution. Examples of colloids are fog and milk.

Heterogeneous mixtures

This is a type of mixture that contain different substances or two or more phases of matter.
The components of heterogeneous mixtures are not uniform such that different samples of the mixture are not identical to each other.
Examples of heterogeneous mixtures are; blood, soil, Gravel, etc.

Suspension

It is a type of heterogeneous mixture made of larger particles that are visible and normally settles when the mixture is undisturbed.
Examples include, tomato juice, fine sand, etc.
