Answer: Option (a) is correct.

Explanation:

A person with less skills needs to work more or practice more on his abilities in order to improve their athletic ability to build a stronger team.

Over encouragement to lesser skilled person can lead to the development of over confidence. As after over encouragement, the less skilled person can have the illusion of knowing each and everything which is not true for anyone.

As no one is perfect, therefore, over-encouraging lesser skilled players can lead to embarrassment.

Predict the final temperature of 3.50 kg of water in a calorimeter if the water is at 27.5°C before 0.77 oz of noodles containin
BaLLatris [955]

The final temperature of the water is determined as 50.55 ⁰C.

<h3>Final temperature of the water</h3>

The final temperature of the water is determined from the following calculations;

Q = mcΔθ

Δθ = Q/mc

where;

  • Q is the amount of energy = 81 kcal = 338904 J
  • c is specific heat capacity of water = 4,200 J/kgC

Δθ = 338904 /(3.5 x 4200)

Δθ = 23.05 °C

Final temperature = T₁ + Δθ

Final temperature = 27.5°C + 23.05 °C = 50.55 ⁰C.

B) Ethane has the formula C2H6. In terms of electronic structure,
k0ka [10]

Answer:

There is one single covalent bond between two carbon atoms.

Explanation:

We know that sharing of electrons form covalent bonds.

If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.

We found that Hydrogen is having only  1 electron in K shell.

And Carbon on the other hand is having 2 electrons in K shell and 4 electrons in L shell.

So carbon have  4 valence electrons,and it can share 4 bonds with any relevant atom to complete its octet.

And Hydrogen requires  1 electron to complete its doublet.

Alkane general formula C_{n}H_{2n+2}

For ethane n=2

C_{2}H_{4+2} = C_{2}H_{6}

1 Carbon atom is shared by  3 Hydrogen.

The remaining one electron (4-3)=1 of carbon will be shared with another carbon atom.

An image of the sharing of electrons attached below,

Hence we have only  1 covalent bond between the two.

An oxide of nitrogen contains 30.45 mass % N.
N76 [4]

An oxide of nitrogen contains 30.45 mass % N, if the molar mass is 90± 5 g/mol the molecular formula is N₂O₄.

<h3>What is molar mass?</h3>

The molar mass of a chemical compound is determined by dividing its mass by the quantity of that compound, expressed as the number of moles in the sample, measured in moles. A substance's molar mass is one of its properties. The compound's molar mass is an average over numerous samples, which frequently have different masses because of isotopes.

<h3>How to find the molecular formula?</h3>

The whole-number multiple is defined as follows.

Whole-number multiple = \frac{molar mass (g/mol)}{empirical formula mass (g/mol)}

The empirical formula mass is shown below.

Mw of empirical formula = Mw of N+ 2 x (Mw of O)

                                      = 14.01 g/mol + 2 x (16.00 g/mol)

                                      = 46.01 g/mol

With the given molar mass or the molecular formula mass, we can get the whole-number multiple for the compound.

Whole-number multiple = \frac{90 g/mol }{46.01 g/mol} ≈ 2

Multiplying the subscripts of NO2 by 2, the molecular formula is N(1x2)O(2x2)= N2O4.

Based on the molar masses, how can you tell that an equation is balanced?
Ilya [14]
When you work with molar mass, you solve for the quantity of ''Moles'' within the substance by converting Mass. The way you can tell the equation is balanced would be by knowing whether the moles were equivalent on both sides or not. Therefore, if they are equal, it is balanced considering you have the same amount of moles on each side of the equation.
