A metal is a solid material that usually has a hard surface. They are usually malleable, ductile, fusible, and shiny. They are also good conductors of electricity.

Nonmetals are materials that aren't metals, and have no similar properties with metals.

A metalloid is a material that has mixed properties of metals and nonmetals.

2N2 + 3H2 → 2NH3

denis23 [38]

There are two N≡N bonds and three H–H bonds are in reactants.

Given:

The reaction between nitrogen gas and hydrogen gas.

$2N_2+3H_2\rightarrow 2NH_3$

To find:

Bonds on the reactant side

Solution:

$2N_2+3H_2\rightarrow 2NH_3$

Reactants in the reaction = $N_2, H_2$

The bond between nitrogen atoms in single $N_2$ molecule = N≡N (triple bond)

Then in two $N_2$ molecules = 2 N≡N (triple bonds)

The bond between hydrogen atoms in single $H_2$ molecule = H-H (single bond)

Then in three $H_2$ molecules = 3 H-H (single bonds)

Product in the reaction = $NH_3$

The bonds between nitrogen and hydrogen atoms in single $NH_3$ molecule = 3 N-H (single bond)

Then in two $NH_3$ molecules = 6 N-H (single bonds)

So, there are two N≡N bonds and three H–H bonds are in reactants.

Which forces of attraction do you think are stronger, the attractions that are broken or the new attractions that are formed? Ex

jasenka [17]

Answer: The forces of attraction are stronger in new attractions that are formed.

Explanation:

When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.

During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.

Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.

If 11g of a gas occupies 5.6dm'3at s.t.p., calculate it's vapour density (1.0mol of a gas occupies 22.4dm'3at s.t.p.).

11111nata11111 [884]

Answer:

${ \boxed{ \bf{vapour \: density = 2 \times molecular \: mass}}} \\{ \tt{ PV= (\frac{m}{ m_{r}}) RT}} \\ { \tt{3 \times 5.6 = \frac{11}{m _{r}} \times 0.0831 \times 273}} \\ { \tt{m _{r} = 14.85 \: g}} \\ \\ { \bf{vapour \: density = 2 \times m _{r}}} \\ = 2 \times 14.85 \\ = 29.7 \: { \tt{g {dm}^{ - 3} }}$
