Answer:
The Lewis structure is shown below.
Explanation:
In the molecule given, the central atom is the carbon (C), which must do 4 bonds. The other carbons at the molecule must do 4 bonds too, and the hydrogens must do only one bond. So, the central atom does a double bond with each carbon, and each carbon does a single bond with the two hydrogens they're bonded.
After the bonds, the central carbon has no lone pairs of electrons, so the geometry of the molecule must be linear, as shown below.
Answer:
A and C represent elements while B and D represent Compounds
Explanation:
chemical elements cannot be broken down into simpler substances by any chemical reaction. While A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds
<h2>Answer:</h2>
<em>Given data:</em>
1 kilogram = 1,000 grams
how many kilograms is 1,216 grams?
<em>Solution:</em>
1000 grams = 1 kilogram
1 gram = 1/1000 kilograms
1216 grams = 1/1000 * 1216 = 1.216 kilograms.
<em> Hence 1216 grams = 1.216 kilograms.</em>
Explanation;
Writing scientific notation :
- Move the decimal to the left side until single digit of number remains before the decimal.
- Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
- For Example:
Radius of the sun = 696,000.0 kilometer
Radius of the sun can also be written as = 
Size of bacterial cell = 
millimeter
Size of bacterial cell can also be written as =
