Ions have a negative or positive charge because silver is metal. It is a cation (Ion with a positive charge).
Answer:
B. Write the chemical equation using formulas and symbols.
D. Count the atoms in each substance in the reactants and products,
Explanation:
When balancing chemical equation, it implies that the law of conservation of matter be strictly adhered to.
By so doing, the number of atoms on both sides of the reaction must be the same. Number of atoms in the products and reactants must have the same value.
- It is always a good approach to first write the chemical equation of the reaction.
- This will give an overview of the reacting species and the products being formed.
- Then, go on to count the number atoms in the reactants and product sides of the expression.
- Then balance it using any of the method of balancing chemical equations.
Answer:
4.55 mol of C₂H₂
Explanation:
Let's verify the reaction:
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
Ratio is 1:1, so 1 mol of calcium carbide will produce 1 mol of acetylene.
4.55 mol of CaC₂ will make the same amount of C₂H₂
Transferring heat through electromagnetic waves
when you hit a chemical with hammer and it was frozen only its physical properties will change and not he chemical properties,
when heated it may decompose to other chemical
when you hit with hamer it physical appearance will change but it remains chemically the same
when you put in salt solution , it wil interact with ions and its chemical properties changes
similarly when it was frozen, it retains its chemical properties.
