Answer:

Explanation:

Protons and neutrons make up nearly all the mass of an atom, and each is worth 1 amu. Each atom of an element has a mass measured in amu; thus, its weighted average, or atomic mass, is measured in amu.

Electrons are way way way....lighter so protons and neutrons are taken into account when doing atomic mass.

Answer:

The correct answer is option a. Protons and neutrons make up nearly all the mass of an atom, and each is worth 1 amu. Each atom of an element has a mass measured in amu; thus, its weighted average, or atomic mass, is measured in amu.

Explanation:

Hello!

Let's solve this!

The unit of atomic mass (amu), which indicates the number of protons plus neutrons present in the nucleus of the atom, measures the mass of the atom.

This means that each of them measures 1 amu and in total they count the mass of the atom.

We conclude that the correct answer is option a. Protons and neutrons make up nearly all the mass of an atom, and each is worth 1 amu. Each atom of an element has a mass measured in amu; thus, its weighted average, or atomic mass, is measured in amu.

Levart [38]

B) convection

Explanation:

Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.

The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.

Heat transfer in fluids is by convection.
It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
Air close to the surface of the ocean is less dense and hot due to high temperature.
The air rises and it is replaced by colder air masses.
This exchange leads to the development of convective cells.
This moves the energy of the sun between the atmosphere and the ocean surface.

What elements can on with other elements to form covalent bonds

Alenkinab [10]

Answer:

Non metals join to form covalent bond.

Explanation:

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

Both atoms bonded through covalent bond.

In Cl₂ both chlorine atoms are bonded through the covalent bond.

You are given an unknown gaseous binary compound (that is, a compound consisting of two different elements). when 10.0 g of the

Luda [366]

Answer is: a possible identity for the unknown compound is C₃H₈.

m(binary compound) = 10.0 g.

m(H₂O) = 16.3 g; mass of water.

M(O₂) = 32 g/mol; molar mass of oxygen.

M(binary compound) = 1.38 · 32 g/mol.

M(binary compound) = 44.16 g/mol.

n(binary compound) = 10 g ÷ 44.16 g/mol.

n(binary compound) = 0.225 mol; amount of substance.

n(H₂O) = 16.3 g ÷ 18 g/mol.

n(H₂O) = 0.9 mol; amount of water.

m(H₂O) : n(binary compound) = 0.9 mol ÷ 0.225 mol.

m(H₂O) : n(binary compound) = 4 : 1.

Unknown cpmpound has 4 times more hydrogen than water, it has 8 hydrogen atoms.

Second element in compound is carbon:

M(X) = 44.16 g/mol - 8 · 1.01 g/mol.

M(X) = 36.08 g/mol ÷ 3.

M(C) = 12.01 g/mol.
