Answer:
C₆H₁₂O₆ + 6O₂ —> 6CO₂ + 6H₂O
Explanation:
Glucose (C₆H₁₂O₆) react with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O).
The equation can be written as follow:
C₆H₁₂O₆ + O₂ —> CO₂ + H₂O
The above equation can be balance as illustrated below:
C₆H₁₂O₆ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 atom on the right side. It can be balance by putting 6 in front of CO₂ as shown below:
C₆H₁₂O₆ + O₂ —> 6CO₂ + H₂O
There are 12 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 6 in front of H₂O as shown below:
C₆H₁₂O₆ + O₂ —> 6CO₂ + 6H₂O
There are a total of 8 atoms of O on the left side and a total of 18 atoms on the right side. It can be balance by 6 in front of O₂ as shown below:
C₆H₁₂O₆ + 6O₂ —> 6CO₂ + 6H₂O
Now, the equation is balanced.

Acetylene gas, C2H2, reacts with oxygen according to the following equation. If 52.0 g of acetylene react completely with sufficient oxygen, how many grams of carbon dioxide are produced
Answer:
176 g of CO₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O
Next, we shall determine the mass of C₂H₂ that reacted and the mass of CO₂ produced from the balanced equation.
This is illustrated below:
Molar mass of C₂H₂ = (2×12) + (2×1)
= 24 + 2 = 26 g/mol
Mass of C₂H₂ from the balanced equation = 2 × 26 = 52 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32 = 44 g/mol
Mass of CO₂ from the balanced equation = 4 × 44 = 176 g
From the calculations made above,
52 g of C₂H₂ reacted to produce 176 g of CO₂.

Thank you so much if you can help me
Which group of elements is considered the most reactive non-metals?
Answer:D. Noble Gases
The noble gasses are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element.#CARRYONLEARNING #STUDYWELLThe halogens will be considered the most reactive non-metals.
What is halogens?The halogens are just a group of 4 - 6 individual elements in a particular periodic table.
What is non-metals?A nonmetal is just a chemical element which lacks the majority of properties associated, ranging from colorless gases to gleaming, high-melting-temperature of the solids.
Each outer shell includes seven electrons, hence group 7 metals would have to gain 1 extra electron to achieve a full outer shell of electrons. When we proceed up the group, this allows us to draw one electron, making it much more reactive.

Part II: Covalent Bonding 1. Now, you will investigate diatomic molecules, those that are made up of two of the same type of atom. Select 2 fluorine atoms. a. How many valence electrons are in each fluorine atom
Answer:
Seven electrons.
Explanation:
There are seven valence electrons in each fluorine atom because it belongs to halogens. Fluorine atom requires one electron to complete its valence shell to become stable so for that it form both ionic and covalent bonds with different atoms. It makes ionic bond with alkali metals by accepting one electron to complete its valence shell and also make covalent bond by sharing of electrons.

Which of the following chemical equations proves that the law of conservation of mass is in effect?
Question 2 options:
Mg2 + LiBr ---> LiMg + Br
2KCl + F2 ---> 2KF + Cl2
Na +O2 ---> Na2O
H20 ---> H2 + O2
Answer:
2KCl + F₂ → 2KF + Cl₂
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
2KCl + F₂ → 2KF + Cl₂
In this equation mass of reactant and product is equal. There are 2 potassium 2 chlorine and fluorine atoms on both side of equation it means mass remain conserved.
All other options are incorrect because mass is not conserved.
Mg₂ + LiBr ---> LiMg + Br
In this equation mass of magnesium is more on reactant side.
Na +O₂ ---> Na₂O
In this equation there is more oxygen and less sodium on reactant side while there is more sodium and less oxygen on product side.
H₂O ---> H₂ + O₂
In this equation there is less oxygen on reactant side while more oxygen on product side.

In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 112. liters per second of dinitroge are consumed when the reaction is run at 17.2°C and 0.88atm.
Required:
Calculate the rate at which ammonia is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits.
Answer: Rate = 0.14 kg/s
Explanation: The Haber reaction is demonstrated below in the balanced equation
[tex]N_{2}+3H_{2}[/tex] → [tex]2NH_{3}[/tex]
To determine the rate of ammonia production, we need to determine the amount of nitrogen gas is being consumed.
As it is a gas, we can find moles by using Ideal Gas Law, whose formula is
PV = nRT
P is pressure
V is volume
n is moles
R is universal gas constant
T is temperature in Kelvin (K)
For the nitrogen gas, temperature will be
T = 273 + 17.2
T = 290.2 K
Solving for moles:
[tex]n=\frac{PV}{RT}[/tex]
[tex]n=\frac{0.88(112)}{0.082(290.2)}[/tex]
n = 4.14 moles
In the Haber reaction, it is consumed 4.14 moles per second of nitrogen gas.
From the balanced equation, we know 1 mol of nitrogen gas produces 2 moles of ammonia, so
[tex]n_{NH_{3}}[/tex] = 2(4.14)
[tex]n_{NH_{3}}[/tex] = 8.48 moles
Number of moles (n) is mass in grams divided by molar mass of the compound:
[tex]n=\frac{m}{M}[/tex]
Molar mass of ammonia is M = 17.031 u, so mass produced is
m = n.M
m = 8.48(17.031)
m = 144.42 g
In kilograms, m = 0.14 kg
When consuming N₂ at a rate of 4.14 moles/s, it will be produced ammonia at a rate of 0.14 kg/s

The reaction of hydrogen sulfide(g) with oxygen(g) to form water(l) and sulfur dioxide(g) proceeds as follows: 2H2S(g) 3O2(g)2H2O(l) 2SO2(g) When 9.82 g H2S(g) reacts with sufficient O2(g), 161 kJ is evolved. Calculate the value of rH for the chemical equation given. kJ/mol
Answer: The value of [tex]\Delta H[/tex] is 1118 .
Explanation:
To calculate the number of moles, we use the equation:
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{molar mass}}[/tex]
[tex]\text{Moles of} H_2S}=\frac{9.82g}{34.1g/mol}=0.288mol[/tex]
The balanced chemical reaction is:
[tex]2H_2S(g)+3O_2(g)\rightarrow 2H_2O(l)+2SO_2(g)[/tex]
Given :
Energy released when 0.288 mole of [tex]H_2S[/tex] is reacted = 161 kJ
Thus Energy released when 2 moles of [tex]H_2S[/tex] is reacted = [tex]\frac{161}{0.288}\times 2=1118kJ[/tex]
Thus the value of [tex]\Delta H[/tex] is 1118.
adding heat and increasing concentration are meant to cause an increase in....?
Answer:
Adding heat and increasing concentration are meant to cause an increase in the rate of a reaction
Explanation:
The rate of a chemical reaction is defined as the number of moles of reactants converted or products formed pee unit time. It is a measure of how quickly the reactants in a given reaction are used up to form products or how quickly products are formed from reactants.
Factors that affect the rate of a chemical reaction include:
1. Nature of reactants
2. Concentration/pressure (for gases) of reactants
3. Temperature of reaction mixture
4. Presence of light
5. Presence of a catalyst
The effect of increasing the concentration of reactants for a given chemical reaction is that the reaction rate will increase. This is so because, according to the collision theory of chemical reactions, the frequency of collision between reactant particles which results in a chemical reaction (effective collisions) will increase when the reactant particles are crowded together in a small space due to an increase in their concentration.
The effect of increasing temperature or adding heat to a reaction is that the reaction rate increases. When the heat is added to a reactant particles, the number of particles with energies greater than or equal to the activation energy (the minimum amount of energy that reactant particles must possess for effective collisions) increases. Also, the average speed of the reactant particles increases resulting in a greater frequency of collision. Hence, the rate of the chemical reaction increases.
