Answer: the minimum amount of energy required to break bonds and start a chemical reaction
Explanation: got a 100% on the quick check
Answer: C. Harmful, because it will have a harder time sneaking up on its prey
Explanation: White skin on an alligator would be detrimental because it would not be able to blend in to its surroundings as well, as the white skin would stand out from the greens and browns of the swamps in which alligators normally inhabit. Most alligators also live in warmer climates, so there would not be much opportunity to try and blend into any sort of snow.
I think it’s no, no, yes, yes. But I could very well be wrong
1. friction that’s all i know lol
The balanced chemical equation for the above reaction is as follows ;
Mg + 2HCl —> MgCl2 + H2
The stoichiometry of Mg to HCl is 1:2
This means that 1 mol of Mg reacts with 2 mol of HCl
Equal amounts of both Mg and HCl have been added. One reagent is the limiting reactant and other reactant is in excess.
Limiting reactant is the reagent that is fully used up in the reaction and the amount of Product formed depends on the amount of limiting reactant present.
In this reaction if Mg is the limiting reactant, 4.40 moles of Mg should react with 4.40x2 -8.80 moles of HCl.
But only 4.40 moles of HCl present therefore HCl is the limiting reactant that reacts with 4.40/2 = 2.20 moles of Mg
Stoichiometry of HCl to MgCl2 is 2:1
Since HCl moles reacted -4.40 mol
Then MgCl2 moles formed are 4.40/2 = 2.20 mol of MgCl2
