The answer option which is an incorrect orbital notation is: C. 2d.
A sublevel refers to an energy level that is typically associated with the valence electrons found outside an atomic nucleus.
In Chemistry, there are four (4) main types of sublevel and these includes:
s orbital (sublevel): 3sp orbital (sublevel): 2pd orbital (sublevel): 3df orbital (sublevel): 4fHowever, it is impossible for any atom of a chemical element to have a 2d orbital because electrons are generally located in the s and p orbitals (sublevels) in the second energy level.

How would an apple, potato, and onion all taste the same?
Answer:
If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.

Sodium (Na), how much mass do I need to weigh out?
A: 699g
B: 6.9g
C: 69g
D: 96g
Answer:
c
Explanation:
Molar mass of Na=23g/mol
amount of mole(n)=3
mass=?
therefore,n=m/M
3mol=m/23g/mol
m=23g/mol ×3mol
m=69g.

5.25 x 10^32 atoms of K to grams
Answer:
3.40x10¹⁰ grams
Explanation:
First we convert 5.25x10³² atoms to moles, using Avogadro's number:
5.25x10³² atoms ÷ 6.023x10²³ atoms/mol = 88.72x10⁸ mol
Then we convert K moles to grams, using its molar mass:
88.72x10⁸ mol * 39 g/mol = 3.40x10¹⁰ g
So 5.25x10³² atoms of K would weigh 3.40x10¹⁰ grams.

Why is it true to say that calcium carbonate
has both ionic and covalent bonds? the
Answer:
Calcium carbonate (CaCO3), essentially, is an ionic compound having the bivalent calcium and carbonate ions.
But the carbonate anion is a polyatomic species. The carbon atom is bonded to all the three oxygen atoms by covalent bonds - two carbon-oxygen single bonds and one carbon-oxygen double bond. Owing to resonance, the three carbon-oxygen bonds are also of equal length in the carbonate anion.
Any salt having a polyatomic ion invariably contains both ionic and covalent bonds.

2534=(112)(25)x
help please!
Answer:
0.905
Explanation:
Answer:
x = 181/200
Explanation:
2534 = 112 . 25 . x (Multiply 112 and 25)
2534 = 2800x (Divide by 2800 from both sides)
x = 2534 / 2800 (Simplify)
x = 181/200 or 0.905

Will mark brainliest thank you!!
Answer:
Explanation:
Using Charles Law ,
[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]
Using this formula we have ,
V1= 200cm^3
T1=40+273.15 = 313.15 K
T2 = 100+273.15 = 373.15 k
V2= ?
Hence using above formula simplify it we will get ,
V2 = 238.3 cm^3

49. Carbon-14 has a half-life of 5,730 years. If a sample contained 80 mg originally, how much
is left after 17,190 years?
50. The half-life of cobalt-60 is 5.26 years. If 100 grams are left after 15.78 years, how many
grams were in the original sample?
Answer:
i only found the 49, hope it still helps, mate
49. In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is.
After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left.
After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left .
After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left.
after three half lives or 17190 years, 8.75 g of C-14 will be left.

There are some climates in which there are no living things. true or false
Answer:
True
Explanation:
There are some climates in which there are no living things. The average of the weather is the climate.
What is climate ?Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years.
Every element of our life is impacted by the climate, including our food supplies, transportation systems, clothing choices, and vacation destinations. It significantly affects our future, our health, and our means of subsistence. Climate is the long-term trend of the weather in any given location.
As an illustration, you can anticipate snow in the Northeast in January or hot and muggy weather in the Southeast in July. Climate is this. Extreme values, such as record-breaking high temperatures or heavy rainfall, are also part of the climatic record.
Thus, there are some climates in which there are no living things.
