Answer:
PHYSICAL CHANGE
Explanation:
It doesnt affect the arrangment of the atoms therefore not changinh the substance its self
<h2>Answer:</h2>
The elements that can form basic compounds are;
- Rubidium
- Arsenic
- Silicon
- Antimony
Rubidium, Arsenic, Silicon, Antimony are the substances that can for the basic compounds. I think sulfur also play its role somehow in formation of basic compounds.
Answer:
Explanation
:Both b/c a chemical formula tells you how many and a sketch formula shows how they are bonded together.
Molecular formulas show how many atoms of each element one molecule of a compound contains. Note: Ionic compounds are generally crystalline solids with high melting points. Other compounds, however, have very different properties.
Answer:
Explanation:
All chemical changes requires a substantial amount of energy. Depending on the type of reaction, the energy of reactants and products differs.
In an exothermic chemical change where heat is always given off to the surroundings, the energy of the product is less than that of reactants.
For endothermic changes, the surrounding becomes colder at the end of the reaction. This implies that the heat energy of the product is higher than that of the reactants.
