Please mark me as brainliest and also give me 5 start Thank you

Explanation:

The radioactive element neptunium (atomic number 93) has the electron configuration

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p64f14 5d10 6s2 6p6 7s2 6d1 5f4

The noble gas form is

[Rn] 7s2 6d1 5f4

using the symbol M for the element, write the chemical formula for the compound that forms when element M reacts with iodine.
Anon25 [30]

Answer : The chemical formula for the compound is, MI

Explanation :

When the element 'M' react with the I_2 to give MI.

The balanced chemical reaction is,

2M+I_2\rightarrow 2MI

In this reaction, 'M' is in mono-atomic form and I_2 is in diatomic form.

By the stoichiometry,

2 moles 'M' react with the 1 mole of I_2 to give 2 moles of MI.

Therefore, the chemical formula of the compound is, MI

Which compound is an electrolyte?<br> (1) C6H12O6 (3) CaCl2<br> (2) CH3OH (4) CCl4
slavikrds [6]
I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.

1.42 mol sample of neon gas at a temperature of 13.0 °C is found to occupy a volume of 25.5 liters. The pressure of this gas sam
Dima020 [189]

Answer: 996 mmHg

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = ?

V= Volume of the gas = 25.5 L

T= Temperature of the gas = 13°C = (273+13) K  = 286K

R= Gas constant = 0.0821 atmL/K mol

n=  moles of gas= 1.42

P=\frac{nRT}{V}=\frac{1.42\times 0.0821\times 286}{25.5}=1.31atm=996mmHg      (760mmHg=1atm)

Thus pressure of this gas sample is 996 mm Hg.

2NH.
liq [111]

Answer:

N=2

H=6

Explanation:

1.Balance a chemical equation in terms of moles.

2.Use the balanced equation to construct conversion factors in terms of moles.

3.Calculate moles of one substance from moles of another substance using a balanced chemical equation.

The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products.

(P.s it could also be where you have to solve it in which you have to simplify it first then solve it.) like adding them all up.

Hope this is the answer. :)

The pressure of an enclosed gas depends on:
Elden [556K]
I think the correct answer from the choices listed above is the last option. The pressure of an enclosed gas depends on the number of molecules in a unit volume and their average kinetic energy, its chemical composition, the altitude about sea level and the number of atoms per molecule. Hope this helps. Have a nice day.
