Further explanationGiven
The reaction of Propane(combustion)
Required
Balanced equation
Solution
Reaction
C₃H₈(g)+O₂(g)→CO₂(g)+H₂O(g)
Give a coefficient(the most complex compound = 1) :
C₃H₈(g)+aO₂(g)→bCO₂(g)+cH₂O(g)
Make an equation :
C, left = 3, right=b⇒b=3
H, left = 8, right=2c⇒2c=8⇒c=4
O, left = 2a, right=2b+c⇒2a=2b+c⇒2a=2.3+4⇒2a=10⇒a=5
The equation becomes :
C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g)

Headaches forced onto me. I was forced out of the womb by two women. My mother and my mother's doctor. I was held in adults arms and I hated it. I had to do whatever they said. I had these diapers around my bo.oty and they were so uncomfortable. I got older and I don't know why I listened to country. The only country song I like now is God Made Girls by Rae Lynn. I got older and started asking what inappropriate words meant. My parents told me the exact meanings and didn't censor. I was disgusted and stayed silent for hours. Now I'm my current age and I need to do about 5 math assignments each day all due at 11:59 pm or else they're missing and I have no excuses. I don't get them at all either there's not explanations. In conclusion, life is headaches forced onto me.
Describe one physical property and one chemical property of sodium that you observed.
Answers
Answer:
It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

Easy points. Chemistry question. Put the following molecules in order, from those that require the least energy to break
the carbon-carbon bond to those that require the most energy. Use the letters A, B, and C. Pls explain why
Answers
Explanation:
Molecule C is made up of a triple bond, which requires the most energy to break. Molecule B is made up of a double bond which is not as strong as a triple bond therefore requiring less energy. Molecule A is made up of a single bond which is the least strong thus requiring the least amount of energy.

With what noble gas is the cation in KNO2 isoelectronic?
Answers
Answer:
argon
For example, the K+ ion is isoelectronic with argon. Potassium has 19 electrons and 1 is in the outermost shell: a valence electron. If potassium is ionized and becomes a +1 cation, this is to say that it lost its single valence electron. This is favorable, because it gives potassium a noble gas configuration
Car and Motorcycle engines are controlled by what chemical reaction?
Answers
Car and Motorcycle engines are controlled by a chemical reaction which is controlled by gasoline and oxygen.
What is a Chemical reaction?A chemical reaction may be defined as a process that significantly involves the chemical transformation of one set of chemical substances to another. This process involves the utilization of substances known as reactants that are transformed into other substances known as products.
The fuel in cars and motorcycles delivers the source of energy to them in order to move from one place to another. This fuel significantly contains gasoline which reacts with atmospheric oxygen and results in a small explosion which derives some sort of energy that is finally consumed by the vehicle's engine.
Apart from this, the combustion of fuel is also facilitated in the presence of oxygen which liberates extremely high amounts of carbon dioxide in the atmosphere. This reaction has also occurred in the engines of vehicles.
Therefore, car and Motorcycle engines are controlled by a chemical reaction which is controlled by gasoline and oxygen.

Water is sometimes called the universal solvent because it is a polar molecule that dissolves many substances. which of the following is soluble in water?
A. Ice
B. Metals
C. Oils
D. Salts
Answers
Answer: Salts
Explanation: Salts easily dissolve in water. Salts are always ionic bonds, meaning they dissolve easily.
Ice does not technically dissolve in water since ice is made of water. You can't dissolve a substance in itself.
Metals are obviously not able to dissolve either in water.
Oils do not mix with water, they float on water, meaning they are immiscible.
