Answer:
310.53 g of Cu.
Explanation:
The balanced equation for the reaction is given below:
CuSO₄ + Zn —> ZnSO₄ + Cu
Next, we shall determine the mass of CuSO₄ that reacted and the mass Cu produced from the balanced equation. This can be obtained as follow:
Molar mass of CuSO₄ = 63.5 + 32 + (16×4)
= 63.5 + 32 + 64
= 159.5 g/mol
Mass of CuSO₄ from the balanced equation = 1 × 159.5 = 159.5 g
Molar mass of Cu = 63.5 g/mol
Mass of Cu from the balanced equation = 1 × 63.5 = 63.5 g
Summary:
From the balanced equation above,
159.5 g of CuSO₄ reacted to produce 63.5 g of Cu.
Finally, we shall determine the mass of Cu produced by the reaction of 780 g of CuSO₄. This can be obtained as follow:
From the balanced equation above,
159.5 g of CuSO₄ reacted to produce 63.5 g of Cu.
Therefore, 780 g of CuSO₄ will react to produce = (780 × 63.5)/159.5 = 310.53 g of Cu.
Thus, 310.53 g of Cu were obtained from the reaction.

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

Answers
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)

Group of answer choices

Answers
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.(20 POINTS!!) please help me write a short reference page on chemical bonds (anything helps)

If the grass contains 220,000 kcal of energy, who much energy will be available to the owl?
Answers
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.

Answer:
18.2 g.
Explanation:
You need to first figure out how many moles of nitrogen gas and hydrogen (gas) you have. To do this, use the molar masses of nitrogen gas and hydrogen (gas) on the periodic table. You get the following:
0.535 g. N2 and 1.984 g. H2
Then find out which reactant is the limiting one. In this case, it's N2. The amount of ammonia, then, that would be produced is 2 times the amount of moles of N2. This gives you 1.07 mol, approximately. Then multiply this by the molar mass of ammonia to find your answer of 18.2 g.

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.

Answers
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.

Answers
Answer:
Ooo gas laws! fun! the answer is B, 1600 kPa
Explanation:
Here are some key things to remember:
- to convert Celsius to Kelvin add 273
- we are using the equation [tex]P1 x T1 = P2 x T2[/tex] our given variables:P1=800kPa T1= 327 + 273 = 600 KP2= ? (decrease)T2= 27+ 273 = 300 K- rearrange our equation and plug in the numbers to solve.[tex]P2= \frac{P1 x T1}{T2}[/tex][tex]800 kPa = \frac{600 K}{300 K}[/tex]- Our Kelvin cancels out so that leaves us with the measurment of kPa. When the numbers are solved out, you get 1600 kPaIn the above picture a solid aluminium rod is being heated by a flame. Explain the main reason why Glob
