A combustion reaction occurs between 9.5 mol of O₂ and 137 g C₂H₄. upon the completion of the reaction . yes, there is C₂H₄ remaining.
The balanced chemical equation is given as :
C₂H₄ + 3O₂ ------> 2CO₂ + 2H₂O
moles of O₂ = 9.5
moles of C₂H₄ = mass / molar mass
= 137 / 28
= 4.8 mol
1 mole of C₂H₄ react with 3 mole of O₂
so, 9.5 O₂ wiil react with = 9.5 / 3 C₂H₄
= 3.1 mol of C₂H₄
we need 4.8 mol of C₂H₄ , therefore there will be C₂H₄ remaining.
Thus, A combustion reaction occurs between 9.5 mol of O₂ and 137 g C₂H₄. upon the completion of the reaction . yes there is C₂H₄ remaining.

what is the concentration of a solution made by diluting 75 ml of 6.0 m hcl to a final volume of 750 ml?
The concentration of a solution made by diluting 75 ml of 6.0 m hcl to a final volume of 750 ml is 0.6 M.
Given that :
molarity of solution M1 = 6.0 M
volume of the solution V1 = 750 mL
molarity of solution after dilution M2 = ?
Volume of solution after dilution V2 = 750 mL
using the dilution law we get :
M1 V1 = M2 V2
M2 = M1 V1 / V2
M2 = ( 6 × 75 ) / 750
M2 = 0.6 M

Limiting reagents are substances that are completely used up or consumed in a chemical reaction, they are also referred to as limiting reactants as well. According to stoichiometry of chemical reactions a fixed amount are reactants are supposed to react with each other in order to complete the chemical reaction, and if some reagent is less in amount for the reaction then it is considered as limiting reagents.
In the above given reaction we can see that 3 moles of Hydrogen gas are required to react with one mole of 1 mole of Nitrogen gas to form 2 moles of Ammonia. But if in case in the reaction only 2 moles of Hydrogen are available with 1 mole of Nitrogen.
In that case we cannot use the whole quantity of Nitrogen, because the whole amount of Nitrogen requires 3 moles of Hydrogen and we have just 2 mole.

What does experimental error entail and how was it calculated?A value's experimental error is the discrepancy between the value that was measured and the actual value. Or, to put it another way, it is the error or inaccuracies that prevent us from seeing a measurement that is 100 percent accurate.
Every measurement has some degree of experimental error, which occurs frequently. The experimental error is determined as follows in this instance.
The formula to determine percent error is percent error = [(approximate value - exact value) / exact value] 100.
Explanation:
Exp takes into account the observed value, in this case 1.4 cm, while theo takes into account the theoretical value, in this case 1.2 cm. As a result, the final number is: Error = (1.4 - 1.2)/1.4 = 0.1428571429 * 100 = 14.3%.

pOH = pKb + log [Conjugate acid] / [Weak base]
pKb is -log Kb = 4.20
pOH = 4.20 + log [N(CH₃)₃] / [NH(CH₃)₃]

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of co2 c o 2.
Each oxygen atom has two lone pairs, so CO₂ has four non-bonding electron pairs. There are two C=O. Due to the bonds in its structure, CO₂ has four bond electron pairs.
Describe the structure of CO₂.Carbon dioxide is a compound consisting of a molecule in which one carbon atom is covalently bonded to two oxygen atoms. It is a gas at room temperature. Carbon dioxide in the air is permeable to visible light but absorbs infrared light, acting as a greenhouse gas.
Each O is surrounded by four dots and two bars or lines, representing the other four electrons in its double bond. Therefore, each O is surrounded by a total of 8 valence electrons, giving it an octet to stabilize it. Carbon dioxide is linear while sulfur dioxide is curved (V-shaped). In carbon dioxide, the two double bonds are pushed as far apart as possible, so the molecule becomes linear.
