Answer:
B
Explanation:
Chemistry is the study of matter, its composition and the changes it undergoes.
Answer:
E
Explanation:
no of grams in picture c = A+B
= 200+10 =210
for D its also 210 ..... the water already contains the salt .....so the mass of salt has added to the mass of water which is still 210
that's all .... have fun
Answer:
The correct option is;
The reaction pathway for the trials is different
Explanation:
The effect of a catalyst in a chemical reaction is to increase the rate of a reaction by changing the pathway or mechanism of the reaction and/or to lower the transition state's energy thereby lowering the activation energy of the reaction
The pathway of the reaction is changed by the catalyst by the formation of intermediate compounds by the catalyst which require lower activation energy to form the products than the original non-catalyzed reactants. In the process the catalyst is regenerated, thereby, not taking part in the reaction.
Their roots trap and stabilize the sediment, which not only helps improve water clarity and quality, but also reduces erosion and buffers coastlines against storms. Sea grass can further improve water quality by absorbing nutrients in runoff from the land.
The answer is B. 6CO2+H2O yields C6H12O6+ 6H20.
