Reactant C is the limiting reactant in this scenario.
Explanation:
The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.
Balanced chemical reaction is:
A + 2B + 3C → 2D + E
number of moles
A = 0.50 mole
B = 0.60 moles
C = 0.90 moles
Taking A as the reactant
1 mole of A reacted to form 2 moles of D
0.50 moles of A will produce 
= 
thus 0.50 moles of A will produce 1 mole of D
Taking B as the reactant
2 moles of B reacted to form 2 moles of D
0.60 moles of B reacted to form x moles of D
= 
x = 2 moles of D is produced.
Taking C as the reactant:
3 moles of C reacted to form 2 moles of D
O.9 moles of C reacted to form x moles of D
= 
= 0.60 moles of D is formed.
Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.
Answer:
Watch the attached image, please.
Explanation:
To complete the Lewis structure for this covalent compound, you have to draw all the atoms with their valence electrons.
The drew has the nitrogen in the center and the fluoride and oxygen in the sides.
Each one of these atoms has to complete the octet rule, which is the ruler who says that all the atoms want to reach to have eight electrons to feel "stable".
For that reason, you have to arrange the atoms to comply with this rule.
Temperature. Water is an example. When water is at room temp. its liquid. When water is at boiling temp. It is a gas. And when water is at freezing temp. Its a solid.
Answer:
Einsteinium is heavier
Explanation:
Atomic weight is what we are referring to when figuring out how heavy an element is and is measured in amu (atomic mass units)
(This is also the same as the molar mass how heavy 6.022 x 10^23 atoms of a substance or element is which is measured in grams)
The atomic weight of an element can be found on a periodic table.
Europium has an atomic mass of approximately 152 amu (atomic mass units)
Einsteinium has an atomic mass of approximately 252 amu.
Einsteinium has a higher atomic weight so it's heavier.
There's another easier way of going about it where you don't even have to think about the actual number and basically just look at the element's atomic number and position on the periodic table.
Eu is 63
Es is 99
As the atomic number increases on the periodic table this means it's number of protons is greater.
Protons lie in the nucleus which has most of the atom's weight so the more protons the heavier it is.
Einsteinium has a higher atomic number meaning it has more protons so we can assume it's the heavier one.
Hope this helps!
The answer should be <span>C. nuclear reaction.</span>
