21 kJ of heat are required to melt 40 g of sodium chloride at its melting point.

The standard enthalpy of fusion of NaCl is 0.52 kJ/g, that is, it takes 0.52 kJ of heat to melt 1 g of NaCl at its melting point. The heat required to melt 40 g of NaCl is:

[tex]40 g \times \frac{0.52kJ}{g} = 21 kJ[/tex]

A neutral atom of nitrogen has electrons in energy level(s):
Select one:
O a. 1 only
O b. 2 only
O c. 1 and 2
O d. 1, 2, and 3

Answers

Answer:

c

Explanation:

Nitrogen is in period 2, and has electrons in both 1 and 2.

The electron seeks to go up to energy level n = 2 from level 1, which is the initial energy level. Since the second energy level has more energy than the first, the electron must gain energy to travel from n = 1 to n = 2. A neutral atom of nitrogen has electrons in energy levels are 1 and 2.

What is energy level ?

Any discrete value from a set of total energy values for a subatomic particle constrained by a force to a finite space or for a system of such particles, such as an atom or a nucleus, is referred to as the energy level, also known as the energy state, in physics.

"Energy levels" refer to the areas around the nucleus where an atom's electrons are positioned. The 3-dimensional region around the nucleus where electrons are most likely to be is represented by an energy level.

Every component of the cycle of wellness depends on energy. Our attitude and physical health both get better as we get more energy. Connecting with people, exercising, and feeling driven to work hard and accomplish personal objectives are all more likely.

Thus, option C is correct.

Answers

Answer:

tomic size is the distance from the nucleus to the valence shell where the valence electrons are located. Atomic size is difficult to measure because it has no definite boundary. The electrons surrounding the nucleus exist in an electron cloud.

Explanation:

Answer:

Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons. and Molecular size is a measure of the area a molecule occupies in three-dimensional space. The amount of space any mass takes up in three-dimensional space is known specifically as its volume.

If you could separate them it would be geat

Answers

Answer:

See explanation

Explanation:

A chemical reaction is said to have occurred when there is a permanent, irreversible change in a substance.

Considering the fruit in the question, the changes in the fruit can not be reversed. Nothing can ever be done to return the fruit to its original form. This ultimately shows that a chemical reaction has taken place.

Secondly, the occurrence of a chemical reaction can be confirmed by evolution of a gas. The foul smell that filled the kitchen is the gas evolved during the chemical reaction involving the rotten fruit.

with explanation plz​

Answers

Answer:

Temperature of gas is 3.21×10² K

Explanation:

Given data:

Volume of bulb = 400 cm³        (400/1000 = 0.4L)

Pressure of bulb = 200 KPa      (200/101= 1.974 atm)

Number of moles of gas = 0.03 mol

Temperature of gas = ?

Solution:

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

1.974 atm × 0.4 L= 0.03 mol ×  0.0821 atm.L/ mol.K × T

0.7896 atm.L = 0.002463 atm.L/K × T

T = 0.7896 atm.L / 0.002463 atm.L/K

Explanation:

Excess reactant: Reactant that has some left over at the end of the reaction

Limiting reactant: Reactant that is entirely used up in the reaction

Theoretical yield: Mass of product that can be made by the given masses of reactants

The terms have been correctly matched to their descriptions as follows:

Limiting reactant: b) Reactant that is entirely used up in the reaction.Theoretical yield: c) Mass of product that can be made by the given masses of reactants.Excess reactant: a) Reactant that has some leftover at the end of the reaction.

What is a Reactant?

A reactant is a chemical compound or element that participates in a chemical reaction.

The limiting reactant is completely used up after the reaction while the excess reactant is the compound or element that is much more than what is normally required to complete the reaction.

The theoretical yield is the maximum quantity of the product that can be formed by the reactants.

A student measured the mass of some sodium chloride for a lab. the lab called for 6.25 g (the accurate measurement ) , but the student measured 6.00 g instead . what is the percent error for this mass ? Show your work .

Answers

Answer:

The answer is

[tex] \huge 4\%[/tex]

Explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual mass = 6.25 g

error = 6.25 - 6 = 0.25

So we have

[tex]p(\%) = \frac{0.25}{6.25} \times 100[/tex]

We have the final answer as

4 %
