How acidic buffer resist change in pH on addition of acid and base.

Chemistry
1 answer:
andrew-mc [135]3 years ago
5 0

Answer:

Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].

hope it's help

Photosynthesis turns sunlight, water and carbon dioxide into energy and oxygen. Clorophyll is also a result of this process. "Photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens." (keep what you wrote there) "It is also an endothermic reaction because SOLAR energy needs to be inputted in order for photosynthesis to occur. The energy input is then stored in the bonds of the glucose that were formed in the plant as a result of photosynthesis."

Look at the following balanced equation. How many atoms of oxygen (O) are present on the reactant side of the equation?
balu736 [363]

There are 6 atoms of oxygen on the reactant side of the following equation: 2Fe2O3 + 3C → 4Fe + 3CO2. Details about atoms can be found below.

<h3>How to find number of atoms?</h3>

The number of atoms of an element in a balanced equation is the amount of that element involved in the reaction.

According to this question, Iron oxide reacts with carbon to produce iron and carbon dioxide as follows:

2Fe2O3 + 3C → 4Fe + 3CO2

In this reaction, 2 × 3 atoms = 6 atoms of oxygen are present on the reactant side of the equation.

Calculate the change in enthalpy for the following reaction, using the bond enthalpy data provided below. (Note: you may round t
aliina [53]

Answer:

-514 kJ/mol

Explanation:

The bond enthalpy which is also known as bond energy can be defined as the amount of energy needed to split one mole of the stated bond. The change in enthalpy of a given reaction can be estimated by subtracting the sum of the bond energies of the reactants from the sum of the bond energies of the products.

For the given chemical reaction, the change in enthalpy of the reaction is:

ΔH_{rxn} = [2(409) + 4(388) + 3(496) - 4(630) - 4(463)] kJ/mol = 818 + 1552 + 1488 - 2520 - 1852 = -514 kJ/mol

Answer:

C.

Explanation:

Since they're changing from a gas to a liquid, the particles are getting squished together more if that makes sense. They're not vibrating that fast anymore when they're in liquid form.
