Based on atomic properties and structure:
- Isotopes have the same proton number(atomic number) but different neutron numbers.
- An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
- The mass number of an atom is determined by the sum of protons and neutrons.
<h3>What are isotopes?</h3>
Isotopes are atoms of an element having the same atomic number but different mass numbers.
The difference in mass number is dues to different neutron numbers.
However, because they have the same proton number, they are atoms of the same element.
Neutral atoms contains equal number of protons and electrons.
An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
The mass number of an atom is determined by the sum of protons and neutrons.

That is a graph read both sides and you see speed and distance which must mean that someone is graphing peoples speed.
Cells have lots of things to do. Some cells make the whole organism, so that one cell must do everything that organism needs to do to live. Other cells perform specific functions, so they must be designed to do that specific activity.
There you go :) just reword it and try make it into your own words like just switch some sentences around
Gallium usually melts at room temperature
Answer:
2molH2O:1molO2
=2molH2÷1molO2
=1molO2
=1molO2÷2molH2O
Explanation:
I have tried My out most ☺️
