Protons and neutrons make up most of an atom's mass. Electrons have almost no mass.
Answer:
electrons
Explanation:
When elements combine to form compounds, chemical bonds form between the atoms. Bonds form when atoms share or exchange electrons in a way that gives each atom a complete outer shell.
For example:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and have complete octet.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
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 have complete octet.
The answer to your question would be D) chemical bonding because when you are bonding atoms to each other you are creating a new and unique substance
Answer:
619.2 K
Explanation:
We can solve this problem by using Charle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically:
where
V is the volume of the gas
T is the absolute temperature
The equation can be rewritten as follows for a gas that undergoes a transformation at constant pressure:
where in this problem:
is the initial volume of the gas
is the initial temperature
is the final volume of the gas
Solving for T2, we find the final temperature:
Converting into Celsius degrees,
