Answer:
Density = 1.11 g/cm³, will not float on water
Explanation:
Assuming the other dimension missing is 4.0 cm
Then we can find the volume of the piece of wood.
Volume = Length × width × height
Volume = 6.0 cm × 3.0 cm × 4.0 cm
= 72 cm³
We are required to find the density of the wood.
Density = mass ÷ Volume
Mass of the wood = 80.0 grams
Therefore;
Density = 80.0 g ÷ 72 cm³
= 1.11 g/cm³
Hence, the density of the wood is 1.11 g/cm³
Water has a density of 1 g/cm³ and therefore the wood will not float since it is denser than water.
Answer:
2
Explanation:
K shell=2
L shell=4
Since carbon has an atomic no of 6 it electron shells are 2 namely kshell and lshell
Answer:
B carbon
Explanation
Lewis structure or dot structure is an easy way to get the bonding details of atoms in a molecule. If we talk about methane molecule carbon is central atom with four electrons that are bonded to four hydrogen atoms and each bond is single covalent bond.
