Answer:

A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure. The DNA sequence found within a gene controls protein synthesis. If the DNA sequence is altered, this can alter the amino acid sequence within a protein

Explanation:

Your DNA is the blueprint used to make proteins. Your DNA is used to make a strand of mRNA (Messenger RNA.) This is sent to a ribosome where it is read. The codons in the mRNA instruct the ribosome which amino-acid to attach to the end of the protein chain and when to let it go.

If your DNA mutates then the mRNA copied from it will be different. When that gets to the ribosome the effect depends on just what the altered codon(s) are. The ribosome will blindly follow the instructions it has been given. This might be to add a different amino-acid to the chain or to prematurely release it.

Vhich of the following equations is correctly balanced?

Eva8 [605]

Answer:

option 3.

2Cr(NO₃)₃ + 3 FeSO₄ → 3 Fe(NO₃)₂ + Cr₂(SO₄)₃

Explanation:

Balance Chemical Equation:

A balanced chemical equation is that in which the number of the reactant atoms equal to the number of the product atom.

For example if the oxygen at the reactant side is 4, the number of oxygen must be 4 on the product side.

Solution

Check each equation one by one

1. Cr(NO₃)₃ + 2 FeSO₄ → 2 Fe(NO₃)₂ + Cr₂(SO₄)₃

Number of atoms of Reactant:

Cr = 1

N = 3

O = 17

Fe = 2

S = 2

Number of atoms of Reactant:

Cr = 2

N = 4

O = 24

Fe = 2

S = 3

So this is not a balance equation as the atoms of the reactant atom not equal to the product atoms.

___________________________________

2. 2Cr(NO₃)₃ + 2 FeSO₄ → 2 Fe(NO₃)₂ + Cr₂(SO₄)₃

Number of atoms of Reactant:

Cr = 2

N = 6

O = 26

Fe = 2

S = 2

Number of atoms of Reactant:

Cr = 2

N = 4

O = 24

Fe = 2

S = 3

So this is not a balance equation as the atoms of the reactant atom not equal to the product atoms.

___________________________________

2Cr(NO₃)₃ + 3 FeSO₄ → 3 Fe(NO₃)₂ + Cr₂(SO₄)₃

Number of atoms of Reactant:

Cr = 2

N = 6

O = 30

Fe = 3

S = 3

Number of atoms of Reactant:

Cr = 2

N = 6

O = 30

Fe = 3

S = 3

So this is a balance equation as the atoms of the reactant atom are equal to the product atoms.

Note** you write Cu and Cl instead of Cr, So that was also corrected.

The reaction of equal molar amounts of benzene, C6H6, and chlorine, Cl2, carried out under special conditions, yields a gas and

WINSTONCH [101]

Answer : The molecular formula of a compound is, $C_6H_5Cl_1$

Solution : Given,

Mass of C = 64.03 g

Mass of H = 4.48 g

Mass of Cl = 31.49 g

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of Cl = 35.5 g/mole

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{64.03g}{12g/mole}=5.34moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{4.48g}{1g/mole}=4.48moles$

Moles of Cl = $\frac{\text{ given mass of Cl}}{\text{ molar mass of Cl}}= \frac{31.49g}{35.5g/mole}=0.887moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{5.34}{0.887}=6.02\approx 6$

For H = $\frac{4.48}{0.887}=5.05\approx 5$

For Cl = $\frac{0.887}{0.887}=1$

The ratio of C : H : Cl = 6 : 5 : 1

The mole ratio of the element is represented by subscripts in empirical formula.

The Empirical formula = $C_6H_5Cl_1$

The empirical formula weight = 6(12) + 5(1) + 1(35.5) = 112.5 gram/eq

Now we have to calculate the molecular formula of the compound.

Formula used :

$n=\frac{\text{Molecular formula}}{\text{Empirical formula weight}}$

$n=\frac{112.5}{112.5}=1$

Molecular formula = $(C_6H_5Cl_1)_n=(C_6H_5Cl_1)_1=C_6H_5Cl_1$

Therefore, the molecular of the compound is, $C_6H_5Cl_1$
