If they fit and have good durability
Answer:
They will repel each other since they have the same charge specifically negative
Explanation:
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.
The answer for this question should be TRUE
Answer:
A. Its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads
Explanation:
Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading.
It combines the high strength compressive properties of concrete with the high tensile strength of steel.

Then the correct answer is:
A. Its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads
