Which diagram shows a p orbital?
Answer:
Third Option
Explanation:
Different orbitals have different shapes. The shapes of the orbitals are given below;
s orbital - Spherical with the nucleus at the center. This matches the second option.
p orbital - It has an elongated like doughnut shape. This matches with the third option in the question.
d orbital - Four of the 5d orbitals are clover leaf shaped. This matches with the first option.

what is the formula name for Co3N2
Answer:
Cobaltous Nitride,I think so anyway.......
The formula name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride.
In the compound [tex]Co_{3}N_{2}[/tex], the Co represents the chemical symbol for cobalt, and the N represents the chemical symbol for nitrogen. The subscript numbers indicate the ratio of atoms present in the compound.
To name the compound, we determine the charge of the cobalt ion based on the ratio of cobalt and nitrogen atoms. In this case, since there are three cobalt atoms and two nitrogen atoms, each cobalt atom has a 2+ charge.
Therefore, the correct name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride. The Roman numeral II is used to indicate the cobalt ion's charge.

What is the ph value of neutral substance
Answer:
Acidity and alkalinity are measured using a pH scale, for which 7.0 is neutral. The lower a substance's pH (less than 7), the more acidic it is; the higher a substance's pH (greater than 7), the more alkaline it is. Average rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it, forming weak carbonic acid. Acid rain usually has a pH between 4.2 and 4.4. The most common nitrogen-related compounds emitted into the air by human activities are nitrogen oxides. Ammonia is another nitrogen compound emitted into the atmosphere, primarily from agricultural activities and fossil fuels. Most of the nitrogen oxides released in the U.S. due to human activity are from the burning of fossil fuels associated with transportation and industry.

carbon. What is the percent of carbon in the compound?
Answer:
14.3% C
Explanation:
27.36 + 1.20 + 57.14 = 85.7

Convert 5.00 moles of carbon to grams. Be sure to report your answer with the correct significant figures.
1 moles Carbon to grams = 12.0107 grams
2 moles Carbon to grams = 24.0214 grams
3 moles Carbon to grams = 36.0321 grams
4 moles Carbon to grams = 48.0428 grams
5 moles Carbon to grams = 60.0535 grams
6 moles Carbon to grams = 72.0642 grams
7 moles Carbon to grams = 84.0749 grams
8 moles Carbon to grams = 96.0856 grams
9 moles Carbon to grams = 108.0963 grams
10 moles Carbon to grams = 120.107 grams
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 60g is the mass of 5.00 moles of carbon.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically, the formula for mole can be given as
mole of carbon =given mass of carbon ÷ molar mass of carbon
number of mole of carbon= 5.00 moles
mass of carbon=?
molar mass of carbon= 12.0107 grams
Substituting the values in above formula we get
5.00 moles = mass of carbon ÷12.0107 grams
On calculations, we get
mass of carbon =60g
Therefore, 60g is the mass of 5.00 moles of carbon.

describe the relationship between the amount of C-15 and time?
Answer:
As time increases, C-15 (Carbon) decreases. During radioactive decay, the amount of Carbon in a substance undergoes half-lives (A sample could have a half life of 1002 years, for example.) When that substance ages to that timeframe, it loses half of its mass. Then for the next half-life, it loses half of that new mass, and so on.

This reaction supports the Law of Conservation of Mass (hint: is the equation balanced?):
2KOH ® K20 + H2O True or
False
Answer:
False
Explanation:
Left:
K = 2 atoms
O = 1 atoms
H = 1 atoms
Right:
K = 2 atoms
O = 1 atoms
H = 2 atoms
O = 1 atoms
As you can see both sides do not have the same amount of atoms, therefore it is not balanced.

what is the ratio of hydrogen(H) to oxygen(O) in hydrogen peroxide(H2O2)?
A 1:1
B 2:2
C 1:2
Answer: 2:2 but if simplified it’s 1:1
Explanation:
For the reaction 2NH3(g) + O2(g) -> 2NO(g) + 3H2O(g). The reaction is run using 824 g NH3 and excess oxygen. How many moles of NO are formed? How many moles of H2O are formed?
Answer:
Explanation:
Step One
Find the molar Mass of NH3
N = 14
3H = 3
Mass = 17
Step Two
Find the number of moles of NH3
mols = given mass / Molar Mass
given mass = 824 grams
molar mass = 17
mols = 824/17
mols = 48.47
Step Three
Find the moles of NO
Here you have to look at the balanced equation
Every 2 mols of HN3 produces 2 mols of NO
So the number of mols of NH3 = 48.47
The number of mols of NO = 48.47
Step Four
Find the mols of H2O
2 mols of NH3 produces 3 moles of H20
48.47 mols H20 produces x moles of H20
3/x = 2/48.47 Cross Multiply
2x = 3*48.47
2x = 145.41 Divide by 2
x = 145.41/2
x = 72.71 mols of water.
