Neutral atoms of neon with atomic number 10 have the same number of electrons as.

Answers

The number of electrons and protons in neon neutral atoms with atomic number 10 is equal. The number of protons in the nucleus is equal to the number of electrons in an electrically neutral atom.

Consequently, there are 10 electrons in the neutral neon atom. The positive nuclear charge and the other (Z - 1) negative electrons in the atom create electric fields that have an impact on each electron. The charge number of an atomic nucleus is the atomic number or nuclear charge number (sign Z) of a chemical element. This is equivalent for conventional nuclei to the proton number (np), or the number of protons present in the nucleus of each atom of that element. The particles with positive charges are called protons.

What benefits does magnesium have?

Magnesium supports muscle and neuron function as well as energy synthesis in the body, among many other vital functions. Typically, low magnesium levels don't result in any symptoms. However, persistently low levels can raise the risk of hypertension, heart disease.

Briefing

We'll start by figuring out how many moles of hydrochloric acid, or HCl, are present in 20.0 mL of the a 3.00 M solution.

This is illustrated below:

Molarity of hcl = 3 M

Volume = 20 mL = 20/1000 = 0.02 L

Mole of HCl =..?

Molarity = mole /Volume

3 = mole /0.02

Cross multiply

Mole of HCl = 3 x 0.02

Mole of HCl = 0.06 mole.

Next, we shall determine the number of mole of Hydrogen gas, H2 produced from the reaction of 0.06 mole of HCl. This can obtain as follow:

Mg + 2HCl —> MgCl2 + H2

From the balanced equation above,

2 moles of HCl reacted to produce 1 mole H2.

Therefore, 0.06 mole of HCl will react to produce = (0.06 x 1)/2 = 0.03 mole

Therefore, 0.03 mole of H2 was produced.

Finally, we shall determine the volume of the balloon by calculating the volume of Hydrogen gas, H2 in the balloon.

The volume of H2 can be obtained by using the ideal gas equation as follow:

Pressure (P) = 1 atm

Temperature (T) = 25°C = 25°C + 273 = 298K

Number of mole (n) of H2 = 0.03 mole

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) of H2 =?

PV = nRT

1 x V = 0.03 x 0.0821 x 298

V = 0.734 L = 734 mL.

Therefore, the volume of the balloon is 0.734 L or 734 mL

Though NaBH4 and LiAlH4 are similar, NaBH4 is less reactive. Esters, amides, acids, and nitriles are largely unaffected; its power is limited to reducing aldehydes, ketones, and acid chlorides to alcohols.

Because the hydride ion can attack the planar carbonyl group on either face, the reduction of unsymmetrical ketones with LiAlH4 or NaBH4 results in the production of two stereoisomers: A racemic mixture of enantiomers results from the absence of any additional chiral centers. The intermediates produced by the reaction of sodium borohydride with water are also mild reducing agents known as hydroxyborohydride. The most popular reaction solvents for reduction or organic substrates are ethanol and propane-2-ol, though methanol is also employed.

how much heat is produced by combustion of 125 g of methanol under standard state conditions? ch3oh 3/2 o2 → co2 2h2o ∆hc

Answers

The heat produced by a combustion of 125g of methanol under standard state of the condition is 2836.29 kJ. The combustion reaction of methanol is 2CH₃OH+3O₂→2CO₂+4H₂O

The value for standard enthalpy of the combustion of a methanol is ΔH°=-726.1kJ/mol. It means that 1 mole of methanol on combustion releases 726.1 kJ of energy. First, we need to find molar mass of CH₃OH.

The molar mass of CH₃OH is

Molar mass=12+(4×1)+16

=12+4+16

=32g/mol

And the number of moles for CH₃OH is

moles=125g×(1 mol/32g)

moles=3.9062 mol

For one mole, we have 726.1 kJ of energy. Hence, energy for 3.9062 mol is

(726.1 kJ/mol)×3.9062 mol

=2836.29 kJ

Therefore, the heat produced by 125g of methanol is 2836.29 kJ.

The amount of heat that is required to melt 5.50 mol of gallium at 1 atm pressure is 33 kJ/mol.

Given that,

Gallium sublimation heat = 277 kj/mol

Gallium vaporization heat = 271 kj/mol

Sublimation, as we know, transforms a sold substance into a gas. Changing from a liquid to a gas is called vaporization.                                        

Hence, using the provided Data, we can derive two equations;

Ga (s)  --> Ga (g) delta, Heat = 277 kJ/mol

Ga (l)  --> Ga (g) delta Heat = 271 kJ/mol

Ga (s) --> Ga (l) delta H = 6 kJ/mol is the result of differentiating these two equations to determine the amount of heat needed to melt one mol.
