If 60. 0 ml of a 1. 5 m hcl solution is put into a flask and diluted with water to make 2. 0 l of solution, what is the molarity of the final solution?.
Answers
The molarity of the final solution is 0.045 M.
To determine the molarity of the final solution, we need to use the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
First, we need to calculate the moles of HCl in the initial 60.0 mL of 1.5 M HCl solution:
Moles of HCl = Molarity x Volume (in liters)
Moles of HCl = 1.5 M x 0.060 L = 0.09 moles
Next, we need to calculate the total volume of the final solution after dilution:
Total volume of final solution = 2.0 L
Now we can calculate the molarity of the final solution:
Molarity = Moles of solute / Volume of solution
Molarity = 0.09 moles / 2.0 L = 0.045 M
Therefore, the molarity of the final solution is 0.045 M.

an automobile gasoline tank holds 43.0 kg of gasoline. when all of the gasoline burns, 153.0 kg of oxygen is consumed, and carbon dioxide and water are produced?
Answers
The total combined mass of carbon dioxide and water that is produced is 196kg.
Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram.
How to calculate the total combined mass of carbon dioxide and water that is produced?
The reaction is written as follows :
Gasoline + 0₂ → CO₂ + H₂O
According to the law of conservation of mass, the total mass of reactants must be equal to the total mass of products as during a reaction, the overall mass of the system remains constant.
So the total mass of reactants is 43kg + 153kg = 196kg
Since mass reactants is equal to the combined mass of products, therefore, combined mass of carbon dioxide and water produced is 196kg.

List and explain four properties of plastics. Give one use of plastics linked to each other of these properties
Answers
Answer:
1.) plastics are poor conductors of heat and electricity
2.) plastics are non reactive metals they are not attacked by chemicals
3.) plastics are lightweight strong and durable
4.) plastics can be moulded and dyed easily in many colours like orange, pink ,sky blue , red, green, and e.t.c
the four uses of plastics are:
1.) bakelite is used to make electric switches insulating casings and handle of cookware and tools
2.) melamine is heat resistant and is used to make kitchenware , floor tiles and special suits for firefighters
3.) Teflon is used as a non stick coating on cookware as both water and oil do not stick to it
4.) many plastics are waterproof and therefore
they are used to make Water bottles and waterproof containers
Explanation:
Search it up bro :')
The four properties of plastics are malleability, longevity, cheapness, and poor conductivity.
Plastics are generally very malleable and can be molded into different shapes very easily. Different types of plastics have different melting points, which enables them to be shaped into different shapes and make objects.
Plastics are generally very durable and have a long shelf life. That is the reason why plastics are used to make things that go through a lot of wear and tear. A negative aspect of this is that plastics, when exposed to natural processes of degradation, do not break down easily and harm the environment.
Plastics are usually cheap and can be obtained at a very less price. This helps people afford goods made out of plastic and also reduces the production cost of the goods.
Plastics are generally very poor conductors of heat and electricity. This means that they do not conduct heat and electricity very well, which is why they are used as insulators and wire coverings.

Hydrolytic reactions are when the bond between two molecules is broken through the splitting of a water molecule, thereby creating two new bonds with the H and OH of that water in its place.
The correct option is E.
Hydrolysis refers to a chemical reaction where a water molecule is broken down into H+ and OH- ions. Hydrolytic reactions involve the cleavage of a chemical bond through the addition of water molecules. They are vital to the digestion of large biomolecules and are used in the synthesis of essential biomolecules, including proteins, RNA, and DNA.
The reaction that happens during a hydrolytic reaction is represented as: AB + H2O → A-H + B-OH In this reaction, the hydrolysis of AB occurs, resulting in A-H and B-OH. Hydrolysis refers to a chemical reaction where a water molecule is broken down into H+ and OH- ions. Hydrolytic reactions involve the cleavage of a chemical bond through the addition of water molecules.

Answers
Answer:
The total amount of time elapsed during the reaction is 2.5227 × 10²s
Explanation:
The total amount of time elapsed in this reaction would be to add the (three) individual time taken together: t = t₁ + t₂ + t₃
(2.514 × 10²s) + (1.4 × 10⁻¹s) + (7.397 × 10¹s) = 252.2797 ⇔ 2.5227 × 10²s

Each reaction has its own unique balanced equation, which provides the ratio of reactants and products.

KOH (s) [H2O ] → K+(aq)+OH−(aq)
The Arrhenius theory, the Brnsted-Lowry theory, and the Lewis theory are the three ideas that have contributed to the definitions of acids and bases over time. According to Arrhenius, an acid is a chemical that, when ionised, releases protons (hydrogen ions) into the solution, whereas a base releases hydroxide ions.
According to Brnsted-Lowry, a base is a proton acceptor and an acid is a proton giver. According to Lewis, a base is an electron-pair donor, while an acid is an electron-pair acceptor
KOH satisfies the Arrhenius theory's definition of a base by producing hydroxide ions when ionised. The hydroxide ion is the base component from a Brnsted-Lowry perspective since it can accept a proton to create water. Although it is a little more difficult to understand from a Lewis perspective why this is a base, the oxygen in the hydroxide has three pairs of non-bonding electrons on it. When a proton (acid) is present, it lacks the electrons necessary to create a covalent link, therefore hydroxide donates an electron pair to the proton in order to build a coordinate covalent bond, which produces water. The three theoretical requirements for a base are thus satisfied by the aforementioned net ionic equation.
