(a) The molecular shapes of cis and Trans forms of N2F2 are-

b) There is EN difference between N atom and F atom. Hence the molecule will have a bond dipole.

In Cis form two fluorine atoms are on the same side of N N bond. Hence, bond moment in N2F2 cis form) do not cancel each other. Thus the cis form is polar.

In the trans form two fluorine atoms are on the opposite side of N-N bond. Bond moment of NF cancels each other.

Thus: trans N2F2 is non polar molecule.

Most metals are very reactive, as are the elements in the halogen group. Aluminum, for instance, For example, reacts with elemen

steposvetlana [31]

Answer: B. you will need 53.2 g Cl2 for complete reaction and will produce 66.7 g of AlCl3.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles of aluminium}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{13.5g}{27g/mol}=0.5moles$

The balanced reaction is:

$2Al+3Cl_2(g)\rightarrow 2AlCl_3$

2 moles of aluminium react with= 3 moles of chlorine

Thus 0.5 moles of aluminium react with= $\frac{3}{2}\times 0.5=0.75$ moles of chlorine

Mass of chlorine= $moles\times {\text{Molar Mass}}=0.75\times 71=53.2g$

2 moles of aluminium produce = 2 moles of aluminium chloride

Thus 0.5 moles of aluminium react with= $\frac{2}{2}\times 0.5=0.5$ moles of aluminium chloride

Mass of aluminium chloride= $moles\times {\text{Molar Mass}}=0.5\times 133.34=66.7g$

Thus 53.2 g of chlorine is used and 66.7 g of aluminium chloride is produced.

Which one of these complementary base pairs can form three hydrogen bonds?

ValentinkaMS [17]

Answer:

Option D is the correct answer

Explanation:

There are three hydrogen bonds formed between Guanine and Cytosine base.

The first hydrogen bond is formed between the oxygen atom on Carbon-6 (C-6) of guanine, and one of the hydrogen atoms attached to the Nitrogen atom (i.e the one of the hydrogen atoms in the amino group) on the Carbon-4 (C-4)of the cytosine base.

The second hydrogen bond is formed between the hydrogen atom on Nitrogen-1 (N-1) of the guanine base and Nitrogen-3 (N-3) of the cytosine base.

The third hydrogen bond exist between one of the hydrogen atoms in the amino group attached to the second Carbon (C-2) of the guanine base, and the oxygen atom attached to the second Carbon (C-2) of the cytosine base.
