Answer:

Atom

Explanation:

An atom is basic unit of all the matter.

Matter can be an element, which has only single kind of atom in it. It is pure form of matter. For example gold is an element and has single kind of atom with same atomic numbers.

Matter can be a compound, which has two or more kinds of atoms.

Neutron, proton and electron are sub atomic particles. Electrons are present around a central unit of atom known as nucleus.

Nucleus contains protons and neutrons both.

Answer:

32.76mole of P

Explanation:

The reaction expression is given as;

P₄O₁₀ → 4P + 5O₂

Given parameters:

Number of moles of P₄O₁₀ = 8.19mol

Unknown:

Number of moles of P produced = ?

Solution:

From the balanced reaction expression;

1 mole of P₄O₁₀ will produce 4 mole of P

8.19mole of P₄O₁₀ will therefore produce 4 x 8.19 = 32.76mole of P

Matter is a physical substance that occupies space.
Lets say you put random stuff in a box. That stuff is matter, filling the box.
Its common to say that matter is everything around you. You can see everything around you (almost).

Trigonal pyramidal has 1 lone pairs and 3 bonds so it is D. PH3
Work: You have to calculate amount of valence electrons for each molecule by looking at the group number and skipping the transition metals. Then you make your Lewis dot structure and see which fits the correct shape. Looking up a molecular geometry chart can help.
