Draw the Lewis structure for CH2O2

Answers

Answer 1

There are 18 valence electrons in total, and eight of them are used to create the four sigma covalent bonds in HCOOH ([tex]CH_{2}O_{2}[/tex]). Lewis structure is given below.

There are 18 valence electrons in the Lewis structure of HCOOH. Eight bonding electrons from them create four sigma covalent bonds in the Lewis structure of HCOOH. The last 10 electrons are non-bonding electrons that are located on the two oxygen atoms of the Lewis structure of HCOOH. Five of the ten non-bonding electrons on the HCOOH Lewis structure, which is supported by two oxygen atoms, are lone pair electrons. There are three lone pair electrons on one oxygen atom and two on another oxygen atom. As a result, there are five lone electron pairs altogether in the HCOOH Lewis structure.

What causes the release of energy in an exothermic reaction? Bonds breaking Bonds breaking A catalyst A catalyst Bonds being formed Bonds being formed Electrons escaping the bond

Answers

Answer:

weak bonds break and strong bonds form

Explanation:

An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.

Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.

Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.

How many moles of KClO3 are needed to produce 480 grams of O2?

Answers

Answer:

2:3

You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.

A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.

Answers

Answer:

1.4 L.

Explanation:

Applying Charles law,

V/T = V'/T'....................... Equation 1

Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.

Make V' the subject of the equation

V' = (V/T)T'..................... Euqation 2

Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K

Substitute these values into equation 2

V' = (1.5/295)275

V' = 1.398

V' ≈ 1.4 L

Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydroxide. The neutralization reaction is shown below HCl + NaOH > H2O + NaCl

Answers

Answer:

1.0M HCl is the concentration of the acid

Explanation:

Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl

Moles NaOH = Moles HCl:

25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl

Molarity:

0.050moles HCl / 0.0500L =

1.0M HCl is the concentration of the acid

Answers

This is the answer:
N2+3H2=2NH3

In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

What is balanced equation ?

A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.

Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.

The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars

Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.

Answers

Answer:

The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution.

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

Molarity is determined by dividing the moles of the solute by the volume of the solution:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

Being 169.87 g / mole the molar mass of AgNO₃, then you can apply the following rule of three: if 169.87 grams are contained in 1 mole, 6.87 grams are contained in how many moles?

[tex]amount of moles=\frac{6.87 grams*1 mole}{169.87 grams}[/tex]

amount of moles= 0.04 moles

Then:

number of moles of solute: 0.04 molesvolume: 2.50 L

Replacing:

[tex]Molarity=\frac{0.04 moles}{2.50 L}[/tex]

Solving:

Molarity= 0.016 [tex]\frac{moles}{L}[/tex]

The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

The molarity of a solution that contains 28 g KOH (molar mass 56 g/mol) per 250 mL of solution is:

Answers

Molarity = moles of solute/volume of solution in liters

The solute here is KOH. We have the mass of KOH, and we can calculate the number of moles by dividing by the molar mass: (28 g KOH)/(56 g/mol) = 0.5 mol KOH. The volume of our solution is 0.250 L.

So, the molarity of the solution would be (0.5 mol KOH)/(0.250 L) = 2 mol/L KOH or 2 M KOH.

Describe how temperature changes the average Molecular kinetic energy?

Answers

an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.

According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.
