Answer:

B and D

Explanation:

Option A is incorrect as it is a neutralization reaction. Option C is incorrect as it an oxidation reaction, the rusting of iron to form iron oxide.  

Option B and D are nuclear reactions called alpha decay.  

In an alpha decay, a helium atom is released, and the daughter nucleus formed has atomic number 2 less than the parent nucleus and mass number 4 less than the parent nucleus.

It is seen that in first and third ones elements are not changed but only their chemical arrangements are changed. both are chemical reactions.

In the second and last one elements are changed after the reaction and as we know non chemical reactions are not capable of doing that so they are nuclear reactions.

There are other ways to tell like checking number of neutrons as well but in this simple case I don't think it is necessary to check those.

Good luck!

Consider n2 (g) + 3h2 (g) →→ 2nh3 (g). what is the mass of nitrogen gas required to react with 0.129 g h2?
Flura [38]
The given chemical reaction given above is already balanced such that the number of atoms in the left hand side of the equation is equal to that of the right hand side. Using the dimensional analysis, proper conversion factors and the molar masses,

                    mass of nitrogen = (0.129 g H₂)(1 mol H₂/2 g H₂)(1 mol N₂/3 mol H₂)(28 g N₂/1 mol N₂)
                     mass of nitrogen = 0.602 g N₂

Therefore, 0.602 g of nitrogen will be required for he reaction.

In the context of the 4ps of the marketing mix, high-tech media options like cell phones and the internet have had a huge impact
mina [271]

In the context of the 4ps of the marketing mix, high-tech media options like cell phones and the internet have had a huge impact on products.

The four Ps represent the crucial factors that must be carefully thought out and put into practice in order to properly advertise a good or service. Product, price, place, and promotion make up this list.

The marketing mix is another name for the four Ps. They cover a wide range of aspects that are taken into account when marketing a product, such as what consumers want, and how the good or service satisfies or doesn't satisfy those wants.

Also on how the good or service is perceived in society, and how it distinguishes itself from the competition, and how the business that makes it engages with its clients.

To learn more about marketing mix refer to:
