The difference between continental drift and plate tectonics is that the theory of continental drift states that the world was made up of a single continent. The theory of plate-tectonics, on the other hand, states that earth's surface is broken into numbers of shifting plates or slabs

Answer:

They both come from the main idea, but the theory of continental drift states that the world was made up of a single large continent. The theory of plate tectonics state that the Earth's surface was broken into smaller pieces.

Which of the quantum numbers relate(s) to the electron only? Which relate(s) to the orbital?
olganol [36]

Answer:

Schrodinger's proposal, considered as the 5th atomic model, is to describe the characteristics of all the electrons in an atom, and for this I use what we know as quantum numbers.

Quantum numbers are called with the letters n, m, l and s and indicate the position and energy of the electron. No electron of the same atom can have the same quantum numbers.

Explanation:

n = main quantum number, which indicates the level of energy where the electron is, assumes positive integer values, from 1 to 7 and it is related to the orbital too.

I = secondary quantum number, which indicates the orbital in which the electron is located, can be s, p, d and f (0, 1, 2 and 3).

m = magnetic quantum number, represents the orientation of the orbitals in space, or the type of orbital, within a specific orbital. Assumes values ​​of the negative secondary quantum number (-l) through zero, to the positive quantum number (+ l).

s = quantum number of spin, which describes the orientation of the electron spin. This number takes into account the rotation of the electron around its own axis as it moves around the nucleus. Assumes only two values ​​+1/2 and - 1/2

In a constant-pressure calorimetry experiment, a reaction gives off 22.8 kJ of heat. The calorimeter contains 150 g of water, in
ludmilkaskok [199]

Answer:

The final temperature of water is 56,7 ºC

Explanation:

We need to apply the specific heat capacity formula to solve this.

Q = m . C . ΔT

22,8 kJ =  150 g . 4,186 J/g °C . (Tfinal - 20,4º C)

(We need to convert kJ in J to use the specific heat of water, be careful with units)

22,8 kJ = 22800 J (x1000)

22800 J  =  150 g . 4,186 J/g °C . (Tfinal - 20,4º C)

22800 J = 627,9 J/ºC (Tfinal - 20,4º C)

22800 J / 627,9 ºC/ J = (Tfinal - 20,4º C)

36,3ºC = Tfinal - 20,4º C

36,3ºC + 20,4º C = 56,7 ºC

A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The re
Arte-miy333 [17]

The mass of nickel is 36.5g metal.

Ni+2AgNO3 → Ni(NO3)2+2Ag

21.5g Ni / 58.69g = 0.366mol Ni

Ag = 107.87

N i= 58.69

But, 2molAg per 1 mol Ni, so, change in mass is more like...

Twice as many moles Ag as Ni, and then the mass relationship is 107.87g Ag / 58.69, but due to the 2Ag: 1Ni mol ratio, the change in mass is like:

107.87(2) / 58.69 = 3.68 times increase

So, the final mass of Ag is 3.68x, and the change in mass of Ni is x

36.5=(21.5-x)+(3.68x)

Solve for x

x=5.597

3.68x=g Ag

3.68(5.597)=20.59

21.5 - x = g Ni after reaction

21.5 - 5.597 = 15.903g Ni

20.59g Ag + 15.903g Ni = 36.5g metal

The mass of nickel is 36.5g metal.
