AS Of Jahuary 2009, the USA has produced 60,000 metric tons of nuclear waste in 60 years of operating 104
nuclear power plants.
On average, how much waste is produced by each plant on a monthly basis?
O0.8tons per month
O83.3 tons per month
104 tons per month
O 866.3 tons per month
Waste produced by each plant : 0.8 tons per month
Further explanationGiven
60,000 metric tons of nuclear waste in 60 years of operating 104
nuclear power plants.
Required
Waste produced
Solution
60,000 metric tons=60 years, so in one year :
[tex]\tt \dfrac{60,000}{60}=1000~metric~tons[/tex]
1000 metric tons/year = 83.33 metric tons/month
For each plant :
[tex]\tt \dfrac{83.33}{104}=0.8[/tex]
Answer:
A. 0.8 tons per month

In the above picture a solid aluminium rod is being heated by a flame. Explain the main reason why Glob
of wax A melts first.
TE from the candle moves through the air and Glob A feels the heat first
TE from the candle transfers particle to particle by touch through the rod to the wax
TE from the candle is carried by particles as they flow though the rod to the wax.
TE travels up as heat rises to the wax
Answer:
TE from the candle is carried by particles as they flow though the rod to the wax.

(20 POINTS!!) please help me write a short reference page on chemical bonds (anything helps)
•differentiate the characteristics of ionic and covalent bonds
•summarize the steps and rules for naming IONIC and COVALENT bonds
•describe the role an elements charge has in writing and naming bonds
- how do roman numerals change the process of naming ionic compounds
have a good day :)
Explanation:An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.
Why does francium react more violently than lithium?
Elements that are most similarities are located in the same...?
Answer: In the same Group
Explanation: Elements in the same group (row going down) have the same number of valance electrons. These valance electrons dictate their chemical properties and how they react with other elements/compounds.

Ralph wanted to breed a pea plant that produced only purple flowers. He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's selective breeding are shown above. What did the selective breeding do to the population of pea plants?
A. increased its genetic diversity
B. decreased its genetic diversity
C. caused a new species of pea plant to form
D. caused a pea plant to exhibit a new characteristic
The correct answer would be that selective breeding decreased the genetic diversity of the population of the pea plants.
The genetic diversity of a population can be viewed as the number of genes in the gene pool of the population.
With each successive generation, more purple-flowered and less white-flowered pea plants were being produced until the 6th generation when only purple-flowered pea plants were produced. The ratio of the purple color gene to that of white color kept increasing until there was no longer a white color gene in the population. Hence, the genetic diversity of the population was decreased by the selective breeding.
The correct option is B

For the reaction Halg) + 12/8) = 2HI(g), K = 50.2 at 445°C. If
[H2] - [62] - [HI] = 1.75 x 10 Mat 445°C, which of the
following is true based on the above?
Qc
equilibrium
Qc - Kc, the reaction is currently at equilibrium
Qc > Kc, the reaction proceeds from left to right to reach
equilibrium
QC > Ke the reaction proceeds from right to left to reach
equilibrium
C) Qc < Kc, the reaction proceeds from left to right to reach equilibrium
Further explanationGiven
K = 50.2 at 445°C
[H2] = [I2] = [HI] = 1.75 × 10⁻³ M At 445ºC
Reaction
H2(g) + I2(g) ⇔2HI(g)
Required
Qc
Solution
Qc for the reaction
[tex]\tt Qc=\dfrac{[HI]^2}{[H_2][I_2]}\\\\Qc=\dfrac{(1.75.10^{-3})^2}{1.75.10^{-3}\times 1.7\times 10^{-3}}=1[/tex]
Qc < Kc ⇒ reaction from left(reactants) to right (products) (the reaction will shift on the right) until it reaches equilibrium (Qc = Kc)

A system does 125 J of work and cools down by releasing 438 J of heat. The change in internal energy is ____________ J.
Given that,
Work done by the system = 125 J
Energy released when it cools down = 438 J
To find,
The change in internal energy.
Solution,
As heat is released by the system, Q = -438 J
Work done by the system, W = -125 J
Using the first law of thermodynamics. The change in internal energy is given by :
[tex]\Delta U=Q-W\\\\=-438-125\\\\=-563\ J[/tex]
So, the change in internal energy is 563 J.

How does kinetic energy relate to particles and the states of matter?
Help??
Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

In equilibrium :
The product decreases ⇒ system will move from left to right(forward reaction)
The product increases ⇒ system will move from right to left(reverse reaction)
If the grass contains 220,000 kcal of energy, who much energy will be available to the owl?
Answer:
Generally, consumers only receive 10% of the energy from what they eat. So, if the grass had 220,000 kcal of energy, then the cow would receive 10% of that - 200kcal. And then when a human eats the cow, it will only receive 10% of the cow's energy. This is because within a food chain, energy is lost as organisms use their energy to survive - like moving and producing heat (if endothermic). So consumers do not get 100% of their food's energy. Hope this helps a little.

Which of the following processes in the water cycle is most directly caused by water absorbing energy from the sun?
Group of answer choices
precipitation
condensation
evaporation
runoff
Answer:
evaporation
Explanation:
The process of evaporation is as a result of water absorbing energy from the sun.
The process is a phase change in which liquid water changes into gaseous form.
The water in gaseous form is called vaporThis water cools and condenses in the atmosphere as it loses the energy it has gained. For evaporation to take place, water must absorb energy from the sun or other heating bodies. This will then cause vaporization of the liquid water into a gaseous form.Which properties do all solids share?

Three quantum numbers are derived from Schrodinger’s equation that describe the probability of finding an electron around a nucleus: the principal quantum number, the angular momentum quantum number, and the magnetic quantum number. Explain each quantum number, including associated shapes, numbers, letters and values.
(please help)
Answer:
Principal Quantum Number (n) = energy level (1s2)
Angular Momentum Quantum Number (l) = sub-shell (1s2)
Magnetic Quantum Number (mi) = specific orbital electron occupies
range of (n) = 1-7
range of (I) = s, p, d , f
Explanation:
Answer:
Principal Quantum Number: designates the principal electron shell. Angular Momentum Quantum Number-This quantum number determines it's shape of an orbital and thus it's angular distribution. This quantum number determines the number of orbital numbers, their orientation within the sub-shell.
Principal Quantum Number, n
It describes the size of its orbital and of the main energy level. It is represented by n. Where, n = 1,2,3,4....stands for K, L, M, N shell and so on..
ngular Momentum Quantum Number l
It describes the shape of the orbital and thus the angular distribution. It can take from 0 to (n - 1). That is l = 0,1,2,...,(n - 1)
The magnetic Quantum Number, m
It describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from . When l = 2, the value of will be -2, -1, 0, +1, +2.

Then plug that answer into the Power formula.
P = W/(t_f-t-i)
P = 400/2s
P = 200 W
