As of January 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 yesrs of operating 104 nuclear power plants.
on average how much waste is produced by each plant on a monthly basis?
a. 0.8 tons p. month
b. 83.3 tons p. month
c. 104 tons p. month
d. 866.3 tons p. month
Answer: a. 0.8 tons p. month.
Explanation:
Given: Total nuclear waste = 60,000 metric tons
Time take = 60 years = 12 x 60 months [ 1 year = 12 months]
= 720 months
Total nuclear power plants = 104
Now , Average waste produced by each plant = [tex]\dfrac{\text{Total waste}}{\text{Time x Number of plants}}[/tex]
[tex]=\dfrac{60000}{720\times104}\approx0.8\text{ tons per month.}[/tex]
Hence, 0.8 tons p. month is produced by each plant.
So, option a. is correct.

Explanation:
Iodine monochloride (ICl) has a higher boiling point than bromine (Br2) partly because iodine monochloride is a(n)
Answer: polar molecule.
Explanation:
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.
Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.
Bromine [tex](Br_2)[/tex] is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.

N in NH3
Answer:
82.35%.
Explanation:
Mass of 1 molecule of ammonia
NH₃ = 14+3(1)
= 17
Calculating percentage by mass of N.
[tex]\%=\dfrac{\text{Mass of Nitrogen atom}}{\text{Mass of ammonia molecule}}\times 100[/tex]
[tex]\%=\dfrac{14}{17}\times 100\\\\=82.35\%[/tex]
So, the required percentage is 82.35%.

When 29 grams of sodium metal (Na) react with 49 grams of chlorine gas (C1), solid
sodium chloride (NaCl) is created in synthesis reaction. How much excess sodium OR
chlorine is left over?
Answer:
Explanation:
Na + Cl = NaCl
23 g 35.5 g
23 g sodium reacts with 35.5 g of chlorine
29 g of sodium reacts with 35.5 x 29 / 23 g of chlorine
= 44.76 g
So 44.76 g of chlorine reacts and 49 - 44.76 = 4.24 g of chlorine is left over .
All the sodium is used up in the reaction .
what chemical reaction type is Pb + 2 H3PO4 --> 3 H2 + Pb3(PO4)2
Answer:
single displacement reaction
Explanation:
it is because an atom(Pb) dispalces another atom(H) in H3PI4
The given chemical reaction is single displacement reaction.
What is single displacement reaction?When one element in a molecule gets replaced by another, is therefore called a single displacement reaction.
The given reaction is Pb + 2 H3PO4 → 3 H2 + Pb3(PO4)2
It can be seen that when lead is treated with H3PO4 then it will give Pb3(PO4)2 and hydrogen reaction. It is a kind of single displacement reaction.
Therefore, the given reaction is single displacement reaction.

How many unpaired electrons are present in V3+?
Answer: two unpaired
Explanation: In general, electrons are removed from the valence-shell s-orbitals before they are removed from valence d-orbitals when transition metals are ionized. And thus, V3+ is paramagnetic, because it has two unpaired 3d-electrons.
What is the molar mass of Sn(CO3)2?
Answer:
The molar mass and molecular weight of Sn(CO3)2 is 238.728.
Explanation:
Molar mass of any molecule can be calculated by adding mass of all individual atoms that comprises the compound. The Molar mass of [tex]Sn(CO_{3})_{2}[/tex] is 238.72g/mol.
What is molar mass?Molar mass is defined as mass of one mole of a molecule or compound. It's SI unit is g/mole. The other term that is used for molar mass is molecular weight, formula unit mass. Molar mass is extensive property as it depends on the mass of individual atoms that constitutes the molecule.
Mass of tin= 118.71 g.mol
Mass of Carbon=12g/mol
mass of Oxygen= 16g/mole
Molar mass of [tex]Sn(CO_{3})_{2}[/tex] = 1×mass of tin+2×mass of carbon+6×mass of oxygen
substituting all the values we get
Molar mass of [tex]Sn(CO_{3})_{2}[/tex] = 1×118.71+2×12g/mol+6× 16g/mole
Molar mass of [tex]Sn(CO_{3})_{2}[/tex] =118.71 +24+66
Molar mass of [tex]Sn(CO_{3})_{2}[/tex]=238.72g/mol
Therefore the Molar mass of [tex]Sn(CO_{3})_{2}[/tex] is 238.72g/mol
