Answer:
sublimation is the transition of a substance directly from the solid to the gas phase without passing throught the intermedate liquid phase
such as the following
dry ice
air fresheners
freese drying
moth balls
Explanation:
Answer:
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.
Explanation:
Newton's law Third law states that forces exist in equal magnitude and for every action force there is an equal and opposite reaction force.
Answer:
Explanation:
Sir Issac Newton successfully derived three laws stating the mechanism of motion of any object. One among the three is the Newton's third law of motion. According to this law, the forces acting on any object will be equal or balanced force with respect to the force of the object itself.
2. Also this law confirmed that the force generated due to this law will be equal in magnitude and opposite in direction with respect to the other force acting on the same object. So every force acting on an object will be having another perpendicular force acting on the same object in opposite direction. This is termed as every action will have an equal and opposite reaction force.
So Newton's law Third law states that forces exist in equal magnitude and for every action force there is an equal and opposite reaction force.
