Answer: ionic bond
Explanation: This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge.
This is true. Gravity is constantly pulling on anything and everything (even light!), no matter how far away it is from another object.
Answer:
testable
Explanation:
high heat can cause browning and or welting
Explanation:
The balanced chemical equation is given as:
2H₂O₂ → O₂ + 2H₂O
А There are two peroxide molecules on the reactant side.
The statement is correct because the left hand side is the reactant side. We can read the reaction as;
2 molecules of hydrogen peroxide decomposed to given 1 molecule of oxygen gas and 2 molecules of water .
D Mass must be conserved so there are an equal number of molecules in the reactants and products.
E Mass must be conserved so there are an equal number of atoms in the reactants and products.
Since the chemical equation is balanced, choices D and E are correct. The reaction will have equal number of molecules and atoms on both sides of the expression.
