True, in space the tail of a comet will be cold since it a. doesnt have a hot core and b. are typically not found near the sun
Answer:
One.
Explanation:
this is the structure of lithium which has valency 1 .Valency means no.electrons present in outermost shell or needed electrons to complete octet
N= g/m therefore g=n*m so you do...
G = 6 * (Molar mass of H2O )
G = 6 * (1.01 x 2)+(16)
G = 6 * (18.02)
G = 108.12 grams of H2O
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.
