the flame ops us a wtare to make it harden
Uranium
simply yes, because if you put them together, then the chemicals collide and therefore makes a chemical change.
An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.
A catalyst is something that speeds up a chemical reaction
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
vinegar and baking soda makes the chemical reaction for swimming raisins
a chemical reaction makes something happen, like rust or water
Uranium
to see if a chemical has changed look out for bubbling and or fizzing
The atoms.
Exothermic chemical reactions release heat.
Water and base
it makes a chemical reaction but not a big one. it just bubbles up and then stops.
There can't be unlimited electrolytes in the battery to make a chemical reaction. The chemical reaction makes electricity to power the device.
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
Raising the temperature makes chemical reactions faster.
Burning of metals in fireworks is a chemical reaction and is what makes the fireworks glow with different colors.
