Cobalt(II) chloride may be a reactant in a chemical reaction.
Yes
could cause chemical reaction
If it is wet, it will get the chemical wet, which will add to its mass, and could cause an undesired reaction. If it is dirty, the substance on the spatula would affect the purity of the chemical, and could cause an unwanted reaction, or could also affect the mass.
it could cause a chemical reaction and may explode
When chemical changes it can cause a chemical reaction..it can fizz or explode or sometimes change temperatures..for example baking soda and vinegar fizz..
The reaction would be termed a chemical reaction.
yes
no, food coloring doesn't cause a chemical reaction, it is essenctially like water.
Any reaction occur.
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
For most reactions, the lowering of the temperature of the reactants.
Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change
No, that's a physical reaction.
vinegar
A chemical reaction is what takes place when two or more opposing chemical come together and cause some sort of reaction, either positive or negative. An example would be mixing bleach and ammonia which will trigger a very noxious smell which can lead to serious illness.
