Answer:
One positive charge
Explanation:
In a neutral atom, the number of positive and negative particles are equal. This leaves the atom with a net charge of zero, 0.
When the number of protons in an atom is greater than the number of electrons, the atom becomes positively charged. When an atom loses an electron when a bond wants to form, it has a net positive charge.
The number of electrons lost or gained determines the charge.
Answer: First subtract 32 degrees, then multiply the result by 5/9 (0.556 on a calculator). For example, suppose a thermometer reads 68 degrees Fahrenheit. Subtract 32 from 68, leaving 36. Multiply 36 by 5/9, which equals 20 degrees Celsius.
Explanation:
Answer:A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution.

Answer:
<u>»</u><u> </u><u>Similarities</u><u> </u><u>:</u>
☑ They both react by chemical means, to produce either an element or compound as the end product of the chemical reaction.
• Take an example of Magnesium reacting with cold water:
• If it reacts with steam:
• [ Element: <em>Magnesium</em><em> </em>and Compound: <em>Water</em><em> </em>]
They are both classified under atomic substances cause they are made up of microscopic molecules known as atoms.
☑ They are both formed up by microscopic substances known as atoms.
<u>»</u><u> </u><u>Differences</u><u> </u><u>:</u>
☑ Compounds generally have higher molecular masses than elements.
☑ Compounds are formed through bonding by elements while elements can naturally exist or formed by extraction, purification and concentration
