Answer:
Energy
Explanation:
Energy can simply be defined as the ability to do work. It is a measure of the amount of work a body or object can do. The more the work a body is able to accomplish, the more the energy it posses. The unit of energy is always expressed in joules.
Mass is the amount of matter in a substance.
Velocity is rate of change of displacement with time.
Answer:
Explanation:
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Neutralization reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example:
Double displacement reaction is one in which exchange of ions take place. Example:
(Missing in the question) solubility in g per 100 mL of water:
CdI2 86.2 (cold water) so,
-We will heat a saturation solution of CdI2 [86.2 g / 100 mL], by the effect of the heat the solution will be unsaturated and dissolve more CdI2 when reaching a high temperature. and let the solution cools again by itself and covers it well to make sure there is no dust in it. when it reaches back to the cold water temperature, we will find the solution is supersaturated and all the solute will stay dissolved.
Answer:
Matals tend to LOSE electrons to become POSITIVE ions
Answer:
False
Explanation:
In Nuclear plants accidents such as explosions can occur which may lead to loss of life or severe injuries.
Nuclear energy production does not produce emissions but it produces radioactive waste which have to be stored adequately to prevent pollution. Since nuclear waste cannot be destroyed, measures have to be taken to adequately store the waste.
If the nuclear plant is being attacked, it can be used as a nuclear weapon to create disaster
