Explanation:
In naming compounds, one has to know the symbol for each element. Magnesium's symbol is Mg. In its ionic form, it is symbolized as Mg2+. Chlorate ions are polyatomic. Chlorite is ClO2-, chlorate is ClO3- and perchlorate is ClO4-. Next, when combining elements to form compounds, you 'cross multiply' their ionic charges. In doing so, Magnesium Chlorate is
Answer:
A tundra has a lower average temperatures year-round.
<h3>Exothermic reactions
</h3>
These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.
Examples:
Combustion
Neutralisation between acids and alkali
<h3>Endothermic reactions
</h3>
These are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.
Example:
Electrolysis
Answer:
Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus
