<h3><em>Answer: Physical properties of a substance are characteristics that can be observed without altering the identity of the substance. Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.</em></h3><h3><em>A pure substance has a definite and constant composition — like salt or sugar. A pure substance can be either an element or a compound, but the composition of a pure substance doesn't vary.</em></h3>
HA+ BCO3 -> BA + H2O + CO2
or
acid + some carbonate -> salt + water + carbon dioxide
the acid is neutralized and produces a salt, water, and co2
Energy=mass*the speed of light^2
The relationship between energy released and the mass of an object.

Answer:</h3>
Sodium
<h3>
Explanation:</h3>
- To answer the question we need to know a few things.
What are cations?
- Cations are positively charged ions that are formed when an atom of an element loses an electron(s).
What elements form cations?
- Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
- For example, alkali metals such as sodium form cations with a charge of +1.
- In this case, sodium will form a cation with a charge of + 1, Na⁺
What are negatively charged ions?
- Negatively charged ions are known as anions.
- They are formed by non-metallic elements such as sulfur, argon, silicon, etc.
No, when ascending, you would weigh more, and when you descend, you weigh less.
This is due to the difference in the effect of gravity.
