What is reaction?A reaction is a procedure or an occurrence in which a change takes place, frequently leading to the conversion of one or more compounds into other substances. A chemical reaction, which entails the rupturing and creation of chemical bonds between atoms or molecules, is what is meant when the word "reaction" is used in reference to chemistry.
When reactant molecules collide with enough force and in the right orientation, the current chemical bonds are broken, and new bonds are formed, converting the reactants into products.

There are various organisms that live in the various zones of the waterbody.
What organism live in the various zones of a water body?Surface or Photic Zone: This is the topmost layer of a water body that receives sunlight. In this zone, there is a high amount of photosynthesis taking place, and as a result, a variety of plants and algae can be found here. Zooplankton, small fish, and other organisms that feed on plants and algae also inhabit this zone.
Thermocline: This is the layer where there is a rapid decrease in temperature with depth. This zone serves as a barrier for the movement of water and nutrients, separating the warm water of the surface from the colder water below.
Benthic Zone: This is the zone at the bottom of the water body, and it is inhabited by organisms that are adapted to life in the absence of light. Benthic organisms include clams, snails, worms, and other bottom-dwelling species.
Abyssal Zone: This is the deep-water zone found in the ocean and is characterized by low temperatures, high pressure, and a complete absence of light. The organisms that live in this zone are typically adapted to these extreme conditions, including deep-sea fish, squid, and crustaceans.

monohalogenated alkane is a haloalkane containing only one halogen atom - correct statement.
what is monohalogenated alkane ?
A halogenation reaction is a chemical reaction that takes place between a material and a halogen in which one or more halogen atoms are integrated into the substance's molecules.
When an alkane is halogenated, a hydrocarbon derivative is formed in which one or more halogen atoms are replaced for hydrogen atoms.
Because they are non-polar and lack functional groups where reactions might occur, alkanes are famously unreactive molecules. As a result, free radical halogenation provides a mechanism for functionalizing alkanes.
The amount of identical C-H bonds found in all but the simplest alkanes, however, is a significant constraint of radical halogenation, making selective reactions difficult to execute.
Monohalogenated alkane: An alkane substituted with one halogen atom instead of a hydrogen atom at any position in the compound.

A 300.0 mL quantity of hydrogen is collected over water at 19.5 C and a total atmospheric pressure of 750. mm Hg. The partial pressure of water at this temperature is 17.0 mm Hg
Answers
The partial pressure of hydrogen in the collected gas sample is 733.0 mm Hg (calculated by subtracting the partial pressure of water, 17.0 mm Hg, from the total atmospheric pressure, 750.0 mm Hg).
When a gas is collected over water, the presence of water vapor affects the total pressure observed. In this case, the total atmospheric pressure is given as 750.0 mm Hg, and the partial pressure of water vapor at 19.5°C is 17.0 mm Hg.
To determine the partial pressure of hydrogen, we need to subtract the partial pressure of water vapor from the total atmospheric pressure. Partial pressure refers to the pressure exerted by an individual gas component in a mixture. In this scenario, the collected gas is primarily hydrogen, with water vapor being the other component.
By subtracting the partial pressure of water vapor (17.0 mm Hg) from the total atmospheric pressure (750.0 mm Hg), we can find the partial pressure of hydrogen:
Partial pressure of hydrogen = Total atmospheric pressure - Partial pressure of water vapor
Partial pressure of hydrogen = 750.0 mm Hg - 17.0 mm Hg
Partial pressure of hydrogen = 733.0 mm Hg
Therefore, the partial pressure of hydrogen in the collected gas sample is 733.0 mm Hg.

If 25.0 g of NH₃ and 45.0g of O₂ react in the following reaction, what is the mass in grams of NO that will be formed? 4 NH₃ (g) + 5 O₂ (g) → 4 NO (g) + 6 H₂O (g)
Answers
Answer:
The correct answer would be : 33.8 g
Explanation:
Molar mass of ammonia,
Molar Mass = 1* Molar Mass(N) + 3* Molar Mass (H)
= 1*14.01 + 3*1.008 = 17.034 g/mol
mass(NH3)= 25.0 g (given)
number of mol of NH3,
n = mass of NH3/molar mass of NH3
=(25.0 g)/(17.034 g/mol)
= 1.468 mol
Now,
Molar mass of O2
= 32 g/mol
mass(O2)= 45.0 g
similar as ammonia
n (O2)=(45.0 g)/(32 g/mol)
= 1.406 mol
Balanced chemical equation is:
4 NH3 + 5 O2 ---> 4 NO + 6 H2O
1.83456 mol of O2 is required for 1.46765 mol of NH3
by the calculation we have only 1.40625 mol of O2
Thus, the limiting agent will be - O2
now the Molar mass of NO,
= 1*14.01 + 1*16.0
= 30.01 g/mol (similar formula used for NH3)
Balanced equation :
mol of NO formed = (4/5)* moles of O2
= (4/5)×1.40625 (from above calculation)
= 1.125 mol
mass of NO = number of moles × molar mass
= 1.125*30.01
= 33.8 g
Thus, the correct answer would be : 33.8 g
The amount of nitrogen oxide that can be formed in the given mass is 44.12 g.
The given parameters;
mass of ammonia, NH₃ = 25.0 gmass of oxygen, O₂ = 45.0 gThe reaction of the ammonia and oxygen is written as follows;
\(4NH_3(g) \ + \ 5O_2 (g) \ --> \ 4NO (g) \ + \ 6H_2O(g)\\\\\)
Molar mass of NH₃ = (14) + (3 x 1) = 17 g/mol
Molar mass of NO = (14) + 16 = 30 g/mol
4(17 g/mol) of NH₃ ------------------ 4(30)
25 g/mol of NH₃ --------------------- ?
\(= \frac{4(30) \times 25}{4(17)} \\\\= 44.12 \ g\)
Thus, the amount of nitrogen oxide that can be formed in the given mass is 44.12 g.

What quantity in moles of CH₂OH are there in 150.0 mL of 0.210 M
CH₂OH?
Answers
Answer:
0.0315 moles CH₂OH
Explanation:
You can find the amount of moles using the molarity equation. This equation looks like this:
Molarity (M) = moles / volume (L)
Once you convert mL to L (by dividing by 1,000), you can plug the molarity and volume into the equation and isolate to find moles. The final answer should have 3 sig figs because the given value with the lowest amount of sig figs (0.210 M) has this amount.
150.0 mL / 1,000 = 0.1500 L
Molarity = moles / volume
0.210 M = moles / 0.1500 L
(0.210 M x 0.1500 L) = moles
0.0315 = moles

Balance the redox reaction.
BrO3- + Pb = Br- + Pb2+
Answers
1. Assign oxidation states to all atoms in the reaction.
BrO3-: Br = +5, O = -2
Pb: Pb = 0
Br-: Br = -1
Pb2+: Pb = +2
2. Identify the atoms that are oxidized and reduced.
BrO3- is reduced (loses oxygen) and Pb is oxidized (gains oxygen).
3. Write out separate half-reactions for oxidation and reduction.
Reduction half-reaction: BrO3- + 6H+ + 6e- → Br- + 3H2O
Oxidation half-reaction: Pb → Pb2+ + 2e-
4. Balance the number of electrons transferred in each half-reaction.
Multiply the oxidation half-reaction by 3 to balance the number of electrons transferred:
3Pb → 3Pb2+ + 6e-
5. Balance the overall charge in each half-reaction by adding H+ or OH- ions as necessary.
Add 6H+ to the reduction half-reaction:
BrO3- + 6H+ + 6e- → Br- + 3H2O
6. Combine the half-reactions and cancel out any common terms.
3Pb + BrO3- + 6H+ → 3Pb2+ + Br- + 3H2O
7. Verify that the atoms and charges are balanced on both sides of the equation.
The balanced equation is:
3Pb + BrO3- + 6H+ → 3Pb2+ + Br- + 3H2O
Therefore, the balanced redox reaction is 3Pb + BrO3- + 6H+ → 3Pb2+ + Br- + 3H2O.

What is a chemical compound?A chemical compound is a substance made of numerous similar molecules (or molecular entities) joined by chemical bonds and comprising atoms from various chemical elements. Therefore, a molecule made up of only one type of atom is not a compound. Chemical reactions, which may entail interactions with other molecules, can change a compound into a distinct substance. Atomic bonds may be broken or new ones created during this process.
What are the calculations?sample 1 = mass of lead / mass of oxygen = 12.92g/2g = 6.46 .
sample 2 = mass of lead/ mass of oxygen = 34.27 - 14.39/14.39 = 1.38 .
