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.

The chemical isoamyl acetate C7H14O2 gives the odor of pears. What is the percent oxygen in isoamyl acetate?
Answer:
[tex]\% O=24.6\%[/tex]
Explanation:
Hello!
In this case, since the by-mass percent of an element in a compound is computed by taking into account its atomic mass, the number of atoms in the molecules and the molar mass of the compound, we can write:
[tex]\% O=\frac{2*16.00}{130.18 } *100\%\\\\\% O=24.6\%[/tex]

What does electronegativity have to do with polarity?
Answer:
Electronegativity is the measure of the ability of an atom to attract electrons to itself. So, higher electronegativity helps atoms take more control over shared electrons creating partial negative regions and partial positive regions which result in dipoles that cause polarity.

The number of particles in one mole of a chemical substances is 602,200,000,000,000,000,000,000 particles. What is the correct way to write this number in scientific notation?
6022 x 10¹⁹
0.6022 x 10²⁴
60.22 x x10²²
6.022 x 10²³
The correct way to write this number in scientific notation : 6.022 x 10²³
Further explanationScientific Notation is a standard form of writing numbers used in mathematical operations
The rules:
1. Writing order : first digit, decimal point, next digit
2. Then followed by powers of 10 (the value can be +/-)
If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit
If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit
I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.

What is the half life if 500 grams decays to 125 grams in 25years?
with steps pls
Answer: The half life of the sample is 60.26 years.
Explanation:
All radioactive decay reactions follow first order reaction.
The formula used to calculate the rate constant for a first order reaction follows:
[tex]k=\frac{2.303}{t}\log \frac{a}{(a-x)}[/tex]
where,
k = rate constant = ?
t = time period = 25 years
a = initial concentration of the reactant = 500 g
a - x = concentration of reactant left after time 't' = (500 - 125) = 375 g
Putting values in above equation, we get:
[tex]k=\frac{2.303}{25yrs}\log \frac{500g}{375g}\\\\k=0.0115yr^{-1}[/tex]
Now, to calculate the half life period of the reaction, we use the equation:
[tex]t_{1/2}=\frac{0.693}{k}[/tex]
where,
[tex]t_{1/2}[/tex] = half life period of the reaction = ?
k = rate constant = [tex]0.0115yr^{-1}[/tex]
Putting values in above equation, we get:
[tex]t_{1/2}=\frac{0.693}{0.0115yr^{-1}}\\\\t_{1/2}=60.26yrs[/tex]
Hence, the half life of the sample is 60.26 years.

What is the pressure in a 29.0-L cylinder filled with 45.5 g of oxygen gas at a temperature of 325 K ?
Answer:
P = 1.29 atm
Explanation:
Given data:
Volume of cylinder= 29.0 L
Mass of oxygen gas = 45.5 g
Temperature = 325 K
Pressure of gas = ?
Solution:
First of all we will calculate the number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 45.5 g/ 32 g/mol
Number of moles = 1.4 mol
Pressure of oxygen:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
P ×29.0 L = 1.4 mol × 0.0821 atm.L/ mol.K × 325 K
P = 37.36 atm. L / 29.0 L
P = 1.29 atm

What percent of a mammal’s genetic material comes from each gamete?
A.10%
B.100%
C.25%
D.50%
Answer:
D.
Explanation:
because gametes are sexual reproducing cells, like sperm and egg cells are gametes. and those make up 50% of you
To solve this we must be knowing each and every concept related to gamete. Therefore, 50% of a mammal’s genetic material comes from each gamete. The correct option is option D.
What is gamete?Sex cells are another frequent name for gametes. The fundamental name for them is "reproductive cells," and they are a component of human reproductive system.
These gametes are indeed the ones that aid in sexual reproduction and they are charge of creating the zygote, a whole new cell that is known as a zygote. These cells are haploid cells, in which each and every gamete typically carries a unique version of the chromosomes. 50% of a mammal’s genetic material comes from each gamete.
Therefore, 50% of a mammal’s genetic material comes from each gamete. The correct option is option D.

Some estimates peg the Milky Way's star mass as having 100 billion "solar masses," or 100 billion times the mass of the sun. Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy. This is subject to change, however, depending on how many stars are bigger and smaller than our own sun. Also, other estimates say the Milky Way could have 200 billion stars or more.

With what noble gas is the cation in KNO2 isoelectronic?
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
