Answer:
Explanation:
NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.
Answer:
The answer to your question is FeS₃
Explanation:
Data
mass of Fe = 3.78g
mass of S = 5.95 g
mass of FeS
Chemical Balanced Reaction
Fe + S ⇒ FeS
Process
1.- Convert the grams to moles
For Iron
55.85g of Fe -------------- 1 mol
3.78 g of Fe ----------- x
x = (3.78 x 1) / 55.85
x = 0.0677 moles
For Sulfur
32 g of S ------------------- 1 mol
5.95 g ------------------ x
x = (5.95 x 1)/32
x = 0.185 moles
2.- Divide by the lowest number of moles
Iron = 0.0677 /0.0677 = 1
Sulfur = 0.185 /0.0677 = 2.73 ≈ 3
3.- Write the empirical formula
FeS₃
N2 + 3 H2 >> 2 NH3
moles NH3 = 11.50 g /17.0307 g/mol=0.6753
the ratio between H2 and NH3 is 3 : 2
moles H2 needed = 0.6753 x 3/2 =1.013
mass H2 = 1.013 mol x 2.106 g/mol=2.042 g
Answer:
- <u><em>50% of the offspring will have green pods.</em></u>
Explanation:
Use a upper case to identify the dominant allele and lower case to identify recessive allele.
<em>A homozygous pea plant</em> would be YY or gg. The <em>homozygous recessive pea pleant</em> would be gg (YY is dominant).
<em>A heterozygous pea plant</em> would be Yg (or gY which is the same).
The <em>Punnett Square </em>for the cross between a <em>homozygous recessive pea plant</em> (gg) and a <em>heterozygous pea plant</em> (Yg) would be:
g g
Y Yg Yg
g gg gg
Hence, <em>the offspring will have</em> two Yg, which would be yellow pods, and two gg which would be green pods.
That is, 50% of the offspring will have yellow pods and 50% will have green pods.
