B) Seawater. Because, it all has the same consistency. With the other choices, like vegetable soup, in one spoon full you may get a bit of potato but in another spoon full you may get a lima bean.
Answer:
When the concentration of a reactant increases, there will be more chemical present. Due to more reactant particles moving together, more collisions are allowed to happen and with that, the rate of the reaction is increased. So, the higher the concentration of reactants, the faster the reaction rate will be.
Hope this helped you! :)
answer:
1) reaction is exothermic
2) some bonds are broken and some are formed (see explanation below)
Explanation:
When energy is written on the product side of a chemical reaction, means that the energy is appearing as consequence of the reaction, that is a released energy (heat) that heats the surroundings.
This kind of reaction where heat is released and, as a consequence, the temperature of the surroundings increase, is called exothermic.
In every chemical reaction some bonds are broken and others are formed.
Breaking bonds requires energy.
Forming bonds release energy.
The energy written on the chemical reaction is a net change of energy: the bonds broken on the reactant side used energy and bonds formed on the products side released energy.
When the energy released by the formation of the product is greater than the energy of the bonds broken on the reactant side, the chemical reaction is exothermic.
The answer is number 2. That releases massive amounts of radiation and by the way, that is how atomic bombs are made to detonate.
