the maximum buffering effect of a weak acid occurs at.....?

Answers

When the ratio of weak acid and its salt in a buffer is equal to 1, it is said that the buffering capacity is maximum.

A buffer is made up of either a weak acid and its salt or a weak base and its salt.

The amount of acid or base that can be added to a given volume of a buffer solution before the pH changes significantly, usually by one unit, is referred to as the buffering capacity. Buffer capacity is determined by the amounts of weak acid and conjugate base present in a buffer mixture.

When NaOH is added to solutions containing varying concentrations of an acetic acid/sodium acetate buffer, the observed change in buffer pH is inversely proportional to the buffer concentration. If the buffer capacity is increased by tenfold, the buffer solution can absorb ten times the amount of strong acid or base previously.

How many moles are in 95 grams of MgCO3

Answers

Answer:

1.1 moles

Explanation:

Stoichiometry allows us to convert units such as grams to moles.

Molar Mass

Before we can convert grams to moles, we need to understand molar mass. Molar mass is the number of grams per mole. For example, the molar mass of oxygen is 16 g/mol. This means that there are 16 grams in one mole. Inversely, there is one mole in 16 grams of oxygen. Molar mass is a constant for each element that can be found on a periodic table.

Now, for this conversion, we need to find the molar mass of MgCO₃. To do this, we need to find the molar mass of each element within the compound.

Mg = 24.3C = 12O = 16

Now, multiply each molar mass by its subscript; then add the molar masses together.

24.3 + 12 + 3(16) = 84.3 grams

The molar mass of MgCO₃ is 84.3 grams.

Converting to Moles

Now we need to use stoichiometry to convert grams to moles. So, we are going to divide the grams by the molar mass.

[tex]95g*\frac{1mol}{84.3g} =1.127 mol[/tex]

So, there are approximately 1.127 moles in 95 grams. However, due to significant figures, we round this to 1.1 moles.

There are 1.1 moles of MgCO3 in 95g.

Which of the following chemical equation represents a decomposition reaction? answer choices. H2SO3 → H2O + SO2. 2K + 2H2O → 2KOH + H2

Answers

The first equation, H2SO3 → H2O + SO2 is an equation that represents a decomposition reaction whereas the second equation, 2K + 2H2O → 2KOH + H2 is a single displacement reaction.

A decomposition reaction is defined as a chemical reaction wherein one reactant among the reactants, breaks down into two or more products.

The general format/formula of a decomposition reaction is:

AB -> A + B

where, AB is the parent molecule i.e. the reactant and A & B are the product molecules of the equation.

A decomposition reaction can be both endothermic (heat absorbing) or exothermic (heat releasing) in nature. However, the latter is more common in nature  than the former.

One of the major applications of decomposition reaction is in the extraction of metals from their respective ores. For example, zinc(Zn) can be obtained/extracted from calamine (ZnCO3) by subjecting it to a decomposition reaction.

The atomic weight of oxygen would be 16 if every known oxygen atom had 8 protons and 8 neutrons.

However, we are aware that some types of oxygen contain fewer than 8 neutrons in their nucleus, which accounts for the slightly below-16 atomic weight of some kinds of oxygen.

As a result, oxygen atoms have eight protons. Oxygen atoms typically have 8 neutrons as well. Oxygen atoms with 8 neutrons would have a mass of roughly 16 amu since their mass number is 16 (8 p+ + 8 n0).

Isotopes are atoms with the same number of protons but differing numbers of neutrons. Various atoms of an element may have different masses because the amount of neutrons for a particular element might change.

As an illustration, certain helium atoms have three neutrons as opposed to two.

Take the atomic number (Z) of 8 for oxygen. As a result, oxygen atoms have eight protons. Oxygen atoms typically have 8 neutrons as well. Oxygen atoms with 8 neutrons would have a mass of roughly 16 amu since their mass number is 16 (8 p+ + 8 n0).

Answers

The limiting reagent is hydrogen gas, and 6 molecules of water are generated.

We receive:

Six molecules make up a hydrogen gas molecule. 6 molecules make up an oxygen gas molecule.

The following is the chemical formula for the reaction between hydrogen gas and oxygen gas:

2H2 + O2 → 2H2O

Using the reaction's stoichiometry:

One oxygen molecule reacts with two molecules of hydrogen gas.

As a result, 6 molecules of hydrogen gas and 1/2 × 6 = 3 molecules of oxygen gas will react.

Since the amount of oxygen gas provided exceeds what is necessary. It is therefore regarded as an excess reagent.

As a result, hydrogen gas is regarded as a limiting reagent since it restricts product formation.

Using the reaction's stoichiometry:

2 molecules of water are created from 2 molecules of hydrogen gas. Thus, 6 molecules of hydrogen gas will result in 2/2 × 6 molecules of water.

As a result, 6 molecules of water are created, with hydrogen gas acting as the limiting reagent.

How does balancing of chemical rection?The algebraic method of balancing a chemical equation involves writing the reactants and products of the reaction as symbols and assigning each side of the equation a numerical coefficient to balance the equation. The coefficients must be rational numbers, and all coefficients must be multiplied by the same number to conserve the number of atoms of each element on both sides of the equation.For example, if a reaction is written as A + B → C, then the coefficients of A and B are multiplied by the same constant until the number of atoms of each element on both sides of the equation is equal. If the coefficients of A and B are 2 and 3 respectively, then they must both be multiplied by 3 to balance the equation, so the balanced equation would be 6A + 9B → C.

In this question

Step 1: Balance the equation.

C2H4 + O2 → CO2 + H2O

2C2H4 + 5O2 → 4CO2 + 2H2O
