<h3><u>Answer;</u></h3>

<em>2 atoms of nitrogen </em>

<h3><u>Explanation;</u></h3>
  • A compound is a substance that is made up of different types of atoms from different elements. For example water is a compound made up of hydrogen and oxygen atoms.
  • In this case; Ni(NO₃)₂, is an example of a compound. It is <u><em>made up of 1 nickel atom,  2 atoms of nitrogen, and six atoms of oxygen</em></u>.

Answer:

The correct answer is two nitrogen atoms.

Explanation:

Hello! Let's solve this!

In the molecule of Ni (NO3) 2 there are two nitrogen atoms. This is a reaction between a compound with Nickel (Ni) that has a valence number +2, and the nitrogen acid. When the hydrogen atom leaves the acid, there is a NO3- ion, this means that it is left with a negative charge. To be able to form the molecule and make it stable we will need 2 NO3- ions.

So in total there are two nitrogen atoms

What happens to the mass, volume, and density of a solid object that is cut in half?
Cloud [144]

If a solid object is cut in half, the mass and volume are both divided by two, but the density remains the same.

<h3>What is an intensive property?</h3>

Intensive property is a property that does not depend on the quantity of a substance while an extensive property depends on the quantity.

Mass and volume is an example of extensive physical property while density is an example of intensive property.

This suggests that if a solid object is cut in half, the mass and volume are both divided by two, but the density remains the same.

Match each organism with its phylum Pines Ephedra Palm-like plants Trees with fan-shaped leaves A. Gnetophyta B. Ginkgophyta C.
solong [7]

Answer:

Ginkgophyta

Explanation:

Gymnosperms are cone-bearing trees or Woody plants, which do not different greatly in their structure from the Woody angiosperms. Gymnosperms do not produce flowers but as seed plants that bear their seeds on scale-like leaves which are arranged spirally to form cones. The seeds are termed naked seeds because they are exposed to the air on the surfaces of the cone scales.

Gymnpsperms are grouped into four major divisions namely:

*Ginkgophyta

*Cycadophyta

*Corniferophyta

*Gnetophyta

1)DIVISION GINKGOPHYTA:The ginkgo tree cared maiden hair is the only surviving member of this division. It is found in the Orient(China and Japan) where it is cultivated as an ornamental tree because of the fan-like leaves. The leaves are *fan-shaped* with long petrioles.

2)DIVISION CYCADOPHYTA:The cycads abound in the tropics, mainly as ornamental plants. They are *palm tree-like* plants with a crowded crown of palm fronds.The leaves of Cuba's are deep green,waxy with large petioles.

DIVISION CONIFEROPHYTA:This is the largest group of Gymnosperms as it includes some of most economically exploited plants such as *pines* and Jupiter's. The pine tree is important as Christmas tree and conifers are generally important in the production of wood and paper

DIVISION GNETOPHYTA:This is the group of very unique Gymnosperms made up of three genera:Gnetum,*Ephedra* and Welwitschia.

Ephedra is a profusely branched shrub found in desert regions. It has whorl-like, scale-like, or needle -like leaves and jointed stem.

Hence, matching each with its phylum, we have:

Gingkophyta:Fan-shaped leaves

Cycadophyta-Palm-like leaves

Coniferophyta:Pine

Gnetophyta:Ephedra
