Question

A little help plz? And don't ignore this one 2 plz...

Answer 1

b)

When hydrogen gas combines with nitrogen to form Ammonia the following chemical reaction will take place.

Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat. In this case, Hydrogen and nitrogen react together to form ammonia.

This will be the balanced chemical reaction when when hydrogen gas combines with nitrogen to form Ammonia.

And the formation of ammonia is an exothermic reaction.

b) IDK why its 2 times,                                   But the Answer is:

Aluminium is highly reactive metal. When aluminium is exposed to air it reacts with oxygen and forms a white thin layer of aluminium oxide on its surface. This layer forms protective coating on aluminium and prevents the reaction of aluminium with oxygen. Aluminium metal with this protective layer is used for making cooking utensils.

c) Oh now I understand,

Copper is used to make hot water tanks and not steel this is because the iron (in steel) is more reactive than then copper also it react with hot steam to produce ferrosoferric oxide. Due to which the body of tank will become weaker and weaker. While copper does not react with hot water.

d)

Structural isomers are molecules that have the same molecular formula but with the atoms connected in a different order.

There are three types of structural isomers.

1. Chain isomers  

In chain isomers, the carbon atoms are connected in different orders.

There are two isomers with the formula C₄H₁₀.

In one of them, butane, the carbon atoms lie in a "straight chain".

In the other, isobutane, the chain is branched, with three C atoms in a row and the fourth attached to the central C atom.

2. Position isomers

In position isomers, the carbon skeleton remains unchanged, but functional groups are moved around.

For example, there are two structural isomers with the molecular formula C₃H₇Br.

In 1-bromopropane, the bromine atom is at the end of the chain. In

2-bromopropane, it's attached in the middle.

You can also get position isomers on benzene rings. Consider the molecular formula C₆H₄Cl₂. You can make four different isomers, depending on the position of the chlorine atoms.

In one case, the Cl atoms are on adjacent C atoms. In the second case, there is a C atom between the ones bearing the Cl atoms. In the third case, the Cl atoms are across the ring from each other.

3. Functional Group Isomers  

In functional group isomers, the atoms are arranged to make different functional groups.

For example, a molecular formula C₃H₆O could be propanal (an aldehyde) or propanone (a ketone).

BTW I hope this HELPs you

And, Please mark it as Bainliest Answer...
