Answer:
I don't know the word bank, but I'll try to answer as best I can
Explanation:
1. The scientific method
2. Variables
3. Procedure
4. Replication
5. Investigation
6. Observation?
7. Hypothesis
8. I don't know, I need the word bank
9. Data
10. Conclusion
Once again, I don't have the word bank, so I don't know for sure.
Have a good day! :)
Answer: Nickel has one more proton.
Explanation:
The Periodic table orders elements based on their atomic number not by their atomic mass even though this order usually coincides with the atomic masses of the elements. Occasionally however, this is not the case as is proven by Cobalt and Nickel.
The atomic number of an element refers to the number of protons that the element has in its nucleus. Cobalt has 27 protons whilst Nickel has one more proton at 28 which is why it comes after Cobalt.
Answer:
When secondary bile salts (or acids) lack a OH, they are reabsorbed
Explanation:
The lost of a hydroxyl group (OH) in the bile salts structure means less hydro solubility. Thus, they are not eliminated, conversely, the are reabsorbed for intestine and they go back to the liver.
I hope my answer helps
Answer:
Because CLEARLY, each mole of glucose, C6H12O6 contains 6⋅mol oxygen atoms.
(g) + OH(g) = (aq) (nitric acid)
Given,
Pressure of = 4.5x10-8 atm,
volume = 1.3x109 L, and
temp = 10ºC + 273 = 283K
moles. NO2 =? = n
PV = nRT
n = PV/RT = (4.5x10-8 atm)(1.3x109 L) / (0.0821 Latm/Kmol) (210K)
n = 3.4x10-18 moles NO2 = mols HNO3
mass HNO3 = 3.4 x 10 18 moles x 31 g/mol = 1.05 x 10 16 g.
<h3>Nitric acid</h3>
The inorganic substance nitric acid has the formula HNO3. This mineral acid is extremely corrosive. [5] Even though the chemical is colorless, older samples often have a yellow tinge from breakdown into nitrogen oxides. Nitric acid is 68 percent concentrated in water in the majority of commercially available products. Fumigating nitric acid is the term used to describe a solution that contains more than 86 percent HNO3. Depending on the quantity of nitrogen dioxide, fuming nitric acid is further classified as red fuming nitric acid at concentrations above 86 percent or white fuming nitric acid at concentrations above 95 percent. The main chemical used in nitration, or adding a nitro group usually to an organic molecule, is nitric acid.
How many grams of nitric acid are produced from this reaction if it reduces the partial pressure of no2 from a 1. 3×109l volume of air over a city by 4. 5×10−8atm when the temperature is 10∘c?
