What electron could have quantum numbers n = 2, l = 1, ml = 0, ms = +?

MrMuchimi

Answer is: electron in 2pz orbital.

The principal quantum number is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state, n=1,2,3... n=2 - the second energy level.
The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital. l = 0,1...n-1, when l = 1, that is p subshell.

The magnetic quantum number, ml, show orbital in which the electron is located, ml = -l...+l, ml = 0 is pz orbital.

The spin quantum number, ms, is the spin of the electron; ms = +1/2 or -1/2.

How many Joules are released to cool 250.0 grams of liquid water from 100°C to 0°C? The specific heat of water is 4.180 J/g.C.

nlexa [21]

$\bold{\huge{\orange{\underline{ Solution}}}}$

$\bold{\underline{ Given :- }}$

We have 250g of liquid water and it needs to be cool at temperature from 100° C to 0° C
Specific heat of water is 4.180J/g°C

$\bold{\underline{ To \: Find :- }}$

We have to find the total number of joules released.

$\bold{\underline{ Let's \:Begin:- }}$

We know that,

Amount of heat energy = mass * specific heat * change in temperature

That is, 

$\sf{\red{ Q = mcΔT }}$

Subsitute the required values in the above formula :-

$\sf{ Q = 250 × 4.180 ×(0 - 100 )}$

$\sf{ Q = 250 × 4.180 × - 100 }$

$\sf{ Q = 250 × - 418}$

$\sf{\pink{ Q = - 104,500 J }}$

Hence, 104,500 J of heat is released to cool 250 grams of liquid water from 100° C to 0° C.

$\bold{\underline{ Now :- }}$

We have to tell whether the above process is endothermic or exothermic :-

Here, In the above process ΔT is negative and as a result of it Q is also negative that means above process is Exothermic

Exothermic process :- It is the process in which heat is evolved .
Endothermic process :- It is the process in which heat is absorbed .

C6H12O6 + 6O2 → 6CO2 + 6H2O is the chemical equation for cellular respiration. What are the products in this reaction?

maks197457 [2]

Answer:

The products are: A) CO2, H2O

Explanation:

Those products that are seen on the right side of the reaction (that is, those substances that are generated from the reagents). In this case they are carbon dioxide and water.

The general equation of cellular respiration is:

C6H1206 + 602 -> 36 ATP + 6CO2 + 6H20

What are 2 of the characteristics of temporary physical change

Natali5045456 [20]

Answer:

Temporary in nature.

No new substance is formed.

Explanation:

Temporary in nature: Does not affect the internal structure of a substance, only the molecules are rearranged.

No new substance is formed: Most of the physical changes are reversible. We can obtain the substance back even after the change.

hope this helps

have an awesome day -TJ

Tom lost money on his peach crops because they kept freezing in the winter. How could Tom most likely solve the problem of his p

vova2212 [387]

Answer:

B. He could breed his peach plants with peach plants that can survive the frost.

Explanation:

Tom can best solve his problem by breeding his peach plants with the ones that can survive the frost.

This is known cross breeding
The goal of cross breeding is to produce offspring that contains the traits of both of the parents or an improved hybrid.
If Tom can cross breed the failing peaches with the successful winter resistant ones, he can ensure better production.
The new hybrid will therefore will be genetically superior and adapted to the prevailing environmental changes.
