Answer:

solid

Explanation:

lithium is a solid so it would still be solid since it is at 100 degrees and has not yet gotten to 180 degrees which is when it melts

Answer:

Earnings based on how much they sell

Explanation:

A sales presentation can be defined as series of talk given by a salesperson with the attempt to persuade someone or a potential customer to buy a particular product, by giving information it. Some salespersons resort to the use of dramatics so as to initiate and close the sale of a particular product by engaging in series of theatrical actions.

In sales and marketing, the term closing with respect to a sales can be defined as the process of making a business sale successful such as through the exchange of money for a particular product or goods.

For a salesperson to be able to close a sales, he or she require abilities such as courage, negotiation skills, listening ears and interpersonal skills to do so or achieve a successful sales. After a successful sales, they're entitled to a percentage of the amount made from selling a particular product or closing a deal based on what is stated in the contract. These amount of money earned with respect to each sales is generally referred to as commissions.

Commission can be defined as an amount of money earned based on how much a salesperson sell.

Answer:

Molarity of a solution is defined as

the amount of a substance in a certain volume of solution or the moles of a solute per liters of a solution and also known as the molar concentration of a solution.

The units of molarity are M or mol/L

Define molarity of a solution.

Molar concentration or Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

Answer:

This formula contains 12 oxygen atoms.

Answer:

3.01×10²⁴ atoms

Explanation:

Our compound is the Na₃PO₄

Sodium phosphate.

We assume, we have 5 moles of the mentioned salt.

1 mol of anything contains 6.02×10²³ atoms.

That's the Avogadro's number. The conversion is:

5 mol . 6.02×10²³ atoms /1mol = 3.01×10²⁴ atoms

Within the system, the energy is flowing from your hand to the ice cream cone. Energy is also flowing from the surroundings to the ice cream cone unless it's reeeeaally cold in the surroundings in which case why are you even holding an ice cream cone when it's that cold?

Answer: 71.43g

Explanation: The RMM of NaHCO3 is

23+1+12+16(3)=84.

There is one carbon in NaHCO3 thus there are 1×12g of C in NaHCO3.

Thus

85gNaHCO3-----12g C

500gNaHCO3---- xgram

(500×12)÷84= 71.43

Answer:

0.89 times

Explanation:

Let the initial volume of the tank be V.

Finally, we shall determine how much larger the final volume of the gas will be. This is illustrated below:

Initial pressure (P₁) = 130 kPa

Initial volume (V₁) = V

Final pressure (P₂) = 145.5 kPa

Final volume (V₂) =?

P₁V₁ = P₂V₂

130 × V = 145.5 × V₂

130V = 145.5 × V₂

Divide both side by 145.5

V₂ = 130V / 145.5

V₂ = 0.89V

Therefore, the final volume of gas will be 0.89 times the initial volume.

Answer:

open the windows, turn off all electronics (take out all of the plugs), then find where the gas is coming from.

The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift.

Answer:

[A]²

Explanation:

Since the formation is independent of D, D is 0 order.

Since a quadruples when it is doubled it can be written as

2A^X= 4

To find the unknown power we can assume A= 1 to make the math simple. So When a = 2 (Because you doubled it) raised to X power it will equal 4

so the unknown power is 2

Making the rate law

[a]²[b]⁰

or simply just

[A]²

Answer:

The plum pudding model of the atom agreed with the nuclear model

Explanation:

Answer:

D) Thomson discovered the atom contained negatively charged electrons.

Explanation:

Without previous discoveries such as the electron, Rutherford would not have generated his nuclear model. So, Thomson had to discover the atom contained negatively charged electrons first.

Answer:

10.8 days (3 sig.figs.)

Explanation:

All radioactive decay is 1st order decay defined by the expression A = A₀e^-kt

which is solved for time of decay (t) => t = ln(A/A₀) / -k

A = final weight = 1.0 gram

A₀ = initial weight = 16.0 grams

k = rate constant = 0.693/t(1/2) = 0.693/2.69 days = 0.258 days⁻¹

t = ln(1/16) / -0.258da⁻¹ = (-2.77/-0.258) days = 10.74646792 days (calculator)

≅ 10 days (1 sig. fig. based on given 1 gram mass)

Explanation:

It is a matter of fact that the hydrophobic (water-hating) oily compounds of cannabinoids such as CBD, THC and others are not water soluble. The term "water soluble" refers to materials which dissolve in water in a homogenous manner by becoming molecules or ions (such as sugar, alcohol, and salt).

Answer:

continuously changing

Explanation:

The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

The question is: Calculate the molar fractions of the components of a solution made up of: 250 g of water, 50 g of acetic acid and 25 g of sodium chloride.

Answer: The mole fraction of water, acetic acid and sodium chloride is 0.916, 0.054, and 0.028.

Explanation:

As number of moles is the mass of substance divided by its molar mass.

Therefore, moles of given species are calculated as follows.

The number of moles of water (molar mass = 18 g/mol):

[tex]Moles = \frac{mass}{molar mass}\\= \frac{250 g}{18 g/mol}\\= 13.88 mol[/tex]

The number of moles of acetic acid (molar mass = 60.052 g/mol):

[tex]Moles = \frac{mass}{molar mass}\\= \frac{50 g}{60.052 g/mol}\\= 0.832 mol[/tex]

The number of moles of sodium chloride (molar mass = 58.44 g/mol):

[tex]Moles = \frac{mass}{molar mass}\\= \frac{25 g}{58.44 g/mol}\\= 0.427 mol[/tex]

Therefore, mole fraction of each component is calculated as follows.

Mole fraction of water:

[tex]Mole fraction = \frac{moles of water}{Total moles}\\= \frac{13.88}{13.88 + 0.832 + 0.427}\\= \frac{13.88}{15.139}\\= 0.916[/tex]

Mole fraction of acetic acid:

[tex]Mole fraction = \frac{moles of water}{Total moles}\\= \frac{0.832}{13.88 + 0.832 + 0.427}\\= \frac{0.832}{15.139}\\= 0.054[/tex]

Mole fraction of NaCl:

[tex]Mole fraction = \frac{moles of water}{Total moles}\\= \frac{0.427}{13.88 + 0.832 + 0.427}\\= \frac{0.427}{15.139}\\= 0.028[/tex]

Thus, we can conclude that mole fraction of water, acetic acid and sodium chloride is 0.916, 0.054, and 0.028.

Answer:

44.91% of Oxygen in Iron (III) hydroxide

Explanation:

To solve this question we must find the molar mass of Fe(OH)3 and the molar mass of the oxygen in this molecule. Percent composition will be:

Molar mass Oxygen / molar mass Fe(OH)3 * 100

Molar mass Fe(OH)3 and oxygen:

1Fe = 55.845g/mol*1 = 55.845

3O = 16.00g/mol*3 = 48.00 - Molar mass of Oxygen

3H = 1.008g/mol*3 = 3.024

55.845 + 48.00 + 3.024 =

106.869g/mol is molar mass of Fe(OH)3

% Composition of oxygen is:

48.00g/mol / 106.869g/mol * 100 =
