Answer: Element 1
Explanation:
If an element has 3 valence shells, then it must be in the third column so element 1 is the right answer. Hope this helps! :)
Answer:
See explanation
Explanation:
∆H is known as the change in enthalpy. When the change in enthalpy is negative, it simply means that heat is given out during the reaction. Therefore, we refer to the reaction as an exothermic reaction.
Similarly, ∆G is known as change in free energy. When the change in free energy is negative, it implies that the reaction is spontaneous as written. This is called an exergonic reaction.
Answer:
cells are too small to see with the naked eye and a microscope magnifies them
Explanation:
<u>Answer:</u>
All of the limiting reagent gets used up causes the percent yield of a reaction to be less than 100%
<u>Explanation:</u>
It is rare for a chemical reaction to occur with the right proportion of reactants that reacts together to form resultant products.During this process, one of the reactants gets used up faster resulting in the lower percent yield. Such product that gets used up faster is called limiting reagent. This limiting reagent is responsible for lowering the percentage yield in the chemical reaction.
The limiting reactant can be found easily by calculating the yield of each reactant assuming they are consumed completely. The reactant which has least yield is the limiting reactant of the reaction.
