According to Avogadro's law, the final volume of container is 6.33 liters.
What is Avogadro's law?Avogadro's law is a gas law which states that the total number of atoms or molecules has a direct proportion to the volume occupied by a gas at a constant temperature and pressure.
It is closely related to ideal gas equation as it links temperature, pressure, volume and the amount of substance.It is given as, V∝n.
The straight line graph of volume versus moles is a straight line passing through the origin which implies that zero moles of gas occupy zero volume.
Substituting values in the formula, V₁/n₁=V₂/n₂ that is V₂=10×1.90/3=6.33 moles.
Thus, the final volume of gas is 6.33 liters.

Vanillin the flavoring agent in vanilla has a mass percent composition of 63.15 per h ,31.55per o. determine the empirical formula and molecular formula if molecular mass of vanillin is 152.15 g/mol
Empirical formula and Molecular formula:
Vanillin has the empirical formula C₈H₈O₃ and the molecular formula C₈H₈O₃, they both are same.
What is Vanillin?
Vanillin has the chemical formula C₈H₈O₃ and is classified as an organic compound. It is an aldehyde that is phenolic. Ether, hydroxyl, and aldehyde are some of their functional groups. It is the key ingredient in vanilla bean extract.C, H, and O are present in this compound,
Mass percent composition = Divide by their atomic mass
C = 63.15/12.0107 = 5.2578
H = 5.30/1.0079 = 5.2582
O = 31.55/16 = 1.9719
Thus, the ratio of
carbon : hydrogen : oxygen
5.257811784 : 5.258249499 : 1.97199825
division of all numbers by the smallest we get,
2.666235523 : 2.666457488 : 1
further dividing it by 3 we get,
7.998706568 : 7.999372463 : 3
thus the ratio becomes 8:8:3
Therefore, the empirical formula is C₈H₈O₃
Empirical formula mass = (12x8) + (1x8) + (16x3)
= 96 + 8 + 48
= 152
n = Molecular mass of Vanillin/ Empirical formula mass
= 152.15/152
= 1.0009
Since the n-value is near to 1 thus the molecular formula will also be the same.
Therefore the molecular formula = C₈H₈O₃
Note: Your question is incomplete, but most probably your full question was Vanillin the flavoring agent in vanilla has a mass percent composition of 63.15 per h ,31.55per o and 5.30%H. determine the empirical formula and molecular formula if molecular mass of vanillin is 152.15 g/mol

How many moles of MgCl₂ are present in 60.0 mL of 0.100 M MgCl₂ solution?
There is 0.0600moles of MgCl2 in 60.0ml of 0.100M MgCl2 solution.
Explanation:
First we need to determine the number of moles of MgCl2 in 60.0L of solution.
After determining the number of moles,now multiply moles of MgCl2 by its Molar mass i.e (95.205g/mol)
We know Molarity= mol of solute/L solution
∴ 0.10 M MgCl2 = 0.10mol MgCl2/L
Step1:
First convert 60.0ml to litres.
1L=1000mL
60.0mL×1L/1000mL=0.0600L
Step2:
To determine moles of MgCl2, multiply 0.0600 L by the molarity of the solution
0.0600L×0.10mL/1L=0.0600mol MgCl2
∴ 0.0600moles of MgCl2 are present in 60.0mL of 0.100M MgCl2 solution.

Taking into account the definition of percentage composition, the percent composition of potassium iodide in this sample is 0.017%.
Definition of percent compositionThe Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.
To calculate the percentage of composition, it is necessary to know the mass of the element in a known mass of the compound.
Percentage Composition in this caseIn this case, you know that a 0.51 kg (or 510000 mg, being 1 kg= 1000000 mg) solution contains 87 mg of potassium iodide.
Dividing the mass amount of potassium iodide present in the compound by the mass of the sample and multiplying it by 100 to obtain a percentage value, the percentage composition of potassium iodide is obtained:
[tex]percentage composition of potassium iodide=\frac{87 mg}{510000 mg} x100[/tex]
percentage composition of potassium iodide= 0.017%

He nitrogen cycle is one of the most important (and complex!) of the biogeochemical cycles. Why is nitrogen important?
Nitrogen is an essential part of proteins and nucleic acids (DNA).
Why is nitrogen important?All living things require nitrogen. It is a part of proteins, ATP, chlorophyll, DNA, and RNA. Given that it makes up a significant portion of the structures of biomolecules in living organisms, its synthesis and consumption in the biogeochemical cycle are of highest importance. Proteins are made up of amino acids (NH2 group).
The structural development of living species' genetic material (DNA, RNA) also involves nitrogen. It is a part of the nitrogenous bases, which together with other nucleotides create RNA and DNA.
Therefore, a nitrogen deficit can cause major structural issues for such an organism.
What happens if nitrogen cycle is disrupted?A number of undesirable consequences can result from the nitrogen cycle being disrupted. For instance, an abundance of nitrogen in aquatic systems leads to eutrophication. Acid rain can be caused by a rise in atmospheric nitrogen.
The majority of ecosystems can tolerate low nitrogen levels since the majority of nitrogen is not biologically accessible in nature. Ecosystems become out of balance when humans significantly increase the quantity of nitrogen that is accessible through fertilizers, fertilizer use, and other means.

an acid accepts H and removes them from a solution, is a solution where the water molecules are intact
When placed in water, acids, bases, and salts dissociate (separate) into electrolytes (ions). Salts dissociate into a cation (that is not H+) and an anion (that is not OH-), whereas acids and bases dissociate into H+ and an anion. An acid separates into anions and hydrogen ions (H+). Strong acids produce a high concentration of H+ by dissociating every single one of their molecules . Water-based solutions,
Acid:
When a material or chemical is in solution, it releases hydrogen ions (H+), which are known as acids. All hydrogen ions (H+) and chloride ions (Cl-), which are normally bound together by ionic bonding, dissociate (separate) in water when exposed to a strong acid like hydrochloric acid (HCl). Only some ions disintegrate into hydrogen ions (H+) and bicarbonate ions (HCO3-) in a weak acid like carbonic acid (H2CO3), while others are still bound together by ionic bonds.
Define base?
A base is a chemical that, when in solution, emits hydroxyl ions -{OH). We can also define a base as a substance that releases hydroxyl ions (OH-), which mix with any hydrogen ions (H+) in the solution to generate water molecules (OH- + H+ = H2O).
Therefore, a substance that receives or accepts hydrogen ions (H+) that are already present in the solution qualifies as a base.
Because it totally dissociates into sodium ions (Na+) and hydroxyl ions (OH-) when placed in water, sodium hydroxide (NaOH), which is a strong base, is now liberated and dissolves in water.

How much energy does a 9 × 108 m wavelength photon have?
Answer:
2.2 x 10⁻³⁴ J
or
2.2 x 10⁻¹⁸ J
Explanation:
You can calculate the energy using the photon energy equation:
E = hc / λ
In this equation,
-----> E = energy (J)
-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)
-----> c = speed of light (3.0 x 10⁸ m/s)
-----> λ = wavelength (m)
You can plug the given wavelength, along with the other constants, into the equation and simplify to find the energy.
E = hc / λ
E = (6.626 x 10⁻³⁴ J*s)(3.0 x 10⁸ m/s) / (9 x 10⁸ m)
E = 2.2 x 10⁻³⁴ J
I suspect that you may have forgotten the negative sign in front of the 8 (9 x 10⁻⁸). This would change your answer to 2.2 x 10⁻¹⁸ J.

Explanation:
From 0 - 7 on the pH scale, substances are said to be acidic. At 7, the substance is said to be neutral. From 7 - 14, substances are basic.
Lime is a basic substance. Therefore, when it is added to the soil, one should expect that the soil becomes more basic. On the graph, this should be represented by the line increasing in pH. As such, the point at which lime was added was most likely Point B.

A Bronsted-Lowry base, on the other hand, takes hydrogen ions. Another way to look at it is that a base accepts protons whereas a Bronsted-Lowry acid donates them. Amphoteric species are those that, depending on the circumstance, can either give or take protons.
Every Bronsted-Lowry acid gives a species that is its conjugate base a proton in exchange for the species' support. Each base in the Bronsted-Lowry system similarly accepts a proton from its conjugate acid.
I understand the question you are looking for is this:
For what mechanistic reason does G1 of lactase first act as a Bronsted acid during catalysis?
A) G1 becomes a better nucleophile
B) G2 becomes a better nucleophile
C) Glucose becomes a better leaving group.
D) Galactose becomes a better leaving group.
