The concentration of species in the reaction changes the reaction in the following ways: decrease carbon dioxide = forward direction of reaction.

The direction of the reaction can be assessed by the following.  On increasing the concentration of the reactant the reaction processes in the forward direction. On increasing the concentration of product the reaction processes in the backward direction.  

The given equilibrium is:

2CO(g) + O2(g) ↔ 2CO2(g)

increase CO = forward direction of reaction  

increase oxygen = forward direction of reaction

decrease CO = no change in equilibrium as reaction not processes.  

decrease oxygen = no change in equilibrium as reaction not processes.  

increase carbon dioxide= reverse direction  

decrease carbon dioxide = forward direction of reaction.

3.2 moles of NaOH will neutralize 1.6 moles of H₂SO₄

A molar ratio is a ratio between the amounts (moles) of any two compounds that participate in a chemical reaction. It is the conversion factor between compounds in a chemical reaction and is derived from the compound's coefficients of the balanced equation. Therefore, molar ratios are used to convert the amounts of compounds in a chemical reaction.

For the given reaction:

H₂SO₄ + 2NaOH = Na₂SO₄ + 2H₂O

The above reaction is a balanced reaction and indicates that two molecules of NaOH are involved with one molecule of H₂SO₄ for neutralization. So, this gives the mole fraction of 1: 2.

Now, considering the mole ratio of H₂SO₄ to NaOH, which is 1: 2. For every mole of the sulphuric acid the reaction requires twice the moles of the sodium hydroxide.

Since the given moles of H₂SO₄ = 1.6 moles

Moles of  NaOH = 2 × 1.6

Answer:

0.3269

Explanation:

You would use the ideal gas law along with the equation Pv=nrt when P is pressure, v is volume, n is the moles of gas you are solving for, r is a constant that is , and t is temperature,

So you are given pressure, volume, and temperature, so you would begin by plugging in your known values:

P = 1atm

V = 8.00 L

T = 298 K ( but you usually want to use Kelvin so you would add 273.15; this is because 0 C is 273.15 K and 25+273=298)

(1)(8)=n(0.0821)(298)

then

8=n(24.4658)

next isolate n by dividing 24.4658 on each side

8/24.4658 = n (24.4658/24.4658)

0.3269=n(1) or n

When AICI and NaOH are combined in an aqueous solution, the following balanced NET ionic equation describes the reaction:

Al(OH)3 -----> Al3+(aq) + 3OH(aq) (s)

An exchange reaction occurs when AICI and NaOH are combined.

Al(OH)3(s) + 3NaCl(aq) -----> AlCl3(aq) + 3NaOH(aq) (1)

In this reaction, the ions Al+3 and Na+ exchange Cl- and OH- ions.

The total ionic equation must first be written in order to create the NET ionic equation:

AI(OH)3(s) + 3Na+(aq) + 3Cl(aq) + Al3+(aq) + 3Cl(aq) + 3Na+(aq) + 3OH (aq) (2)

Since the Al(OH), precipitates, we are unable to describe it as an ion because the aqueous solution does not allow for its dissociation.

Atoms and chemical species lose and gain electrons as they react to gain stability. Therefore, metals usually donate electrons to nonmetals to form cations. The number of electrons depends on their position on the periodic table. When an atom gains an electron, its overall charge becomes negative.

When an atom loses an electron its overall charge becomes positive. When an atom gains or loses electrons, its mass does not change. The number of electrons an atom can lose and gain share during a chemical reaction is called its valence.
