A0 = 1
a1 = 2
a2 = 1
a3 = 2

This can be solved by guessing and checking and making sure that all atoms on the left side are accounted for on the right side. Both sides must have the same amount of atoms or the balancing is not correct.

a0h2so4 + a1koh → a2k2so4 + a3hoh

The balanced chemical reaction is:

H2SO4 + 2KOH → K2SO4 + 2H2O


hence,

a0 = 1

a1 = 2

a2 = 1

a3 = 2

Perform the calculation and report the answer using the proper number of significant figures. Make sure the answer is rounded co
shusha [124]

This question is an incomplete question, here is a complete question.

Perform the following calculation. Report the answer using the proper number of significant figures.

\frac{1.012\times 10^{-3}J}{(0.025456g)\times (298.3682-298.3567)K}=?

Answer : The answer will be, 3.46J/g.K

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

The rule apply for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The rule apply for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

The given expression is,

\frac{1.012\times 10^{-3}J}{(0.025456g)\times (298.3682-298.3567)K}

\frac{1.012\times 10^{-3}J}{(0.025456g)\times (0.0115)K}

\Rightarrow 3.4569J/g.K

In the given expression, 1.012 has 4 significant figures, 0.025456 has 5 significant figures and 0.0115 has 3 significant figures. From this we conclude that 3 is the least significant figures in this problem. So, the answer should be in 3 significant figures.

Thus, the answer will be 3.46J/g.K

A(n) _____ refers to two or more atoms held together by covalent bonds.
arlik [135]

Answer: Option (d) is the correct answer.

Explanation:

A covalent bond is defined as the bond formed by sharing of electrons between the two chemically combining atoms.

For example, atomic number of chlorine is 17 and it has 7 valence electrons.

To attain stability it need to gain one more electron.

So, when one chlorine atom chemically combines with another chlorine atom then there occurs sharing of electrons between the two. As a result, there will be sharing of electrons.

A molecule is defined as the specie that contains same type of atoms which are chemically combined together in a fixed ratio by mass.
