Answer:
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Explanation:
You have to put energy into a molecule to break its chemical bonds. The amount needed is called the bond energy. After all, molecules don't spontaneously break
9.75 x 10^5
A number in scientific notation has the form <em>a x 10^b</em> where
• a is the <em>coefficient</em>
• b is the <em>exponent</em>
Here are the steps to convert a number greater than 1 to scientific notation.
a) Find the coefficient
Put the decimal point after the first digit and drop the trailing zeroes
<u>9.75</u> 000
The coefficient is 9.75
.
b) Find the exponent
Count the number of digits after the first digit.
In 975 000 there are five digits after the 9. Therefore, the exponent is 5.
c) Write the number
We write 975 000 as 9.75 x 10^5.
Combustion reactions always contain products of CO + H2O with the addition of O2 (oxygen) in the reactant.
In this case it would be:
C3H7OH OR C3H8O (if you count up all the H’s)
We’re just going to use C3H7OH since that’s what you were given so it’ll be easier for you that way.
C3H7OH + O2 -> CO2 + H2O
Balanced:
2 C3H7OH + 9 O2 -> 6 CO2 + 8 H2O
