In chemistry, the ball-and-stick model is a molecular ideal of a chemical matter which is to expose both the three-dimensional position of the atoms and the bonds among them. The atoms are normally symbolise by spheres, join by rods which shows the bonds.
Formaldehyde forms formaldehyde structure bond it shares double bond with O2 atoms.
Formaldehyde also known as methanol .
Methanol is colourless.
It is flammable.
It is gas at room temperature.
Methanol having pungent odor and it is a volatile organic compounds.
It is made by the composition of Hydrogen, oxygen, and carbons.

Answer:
The molecular formula of glucose is C₆H₁₂O₆
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of smallest whole number of atoms.
Molecular formula:
It gives the total number of atoms in a molecule of compound.
The molecular formula and empirical formula can be related as follow:
Molecular formula = n × empirical formula
Given data:
Empirical formula = CH₂O
Molecular formula = ?
It is stated in given problem that molecular formula is the 6 times of the empirical formula.
Molecular formula = n × empirical formula
Molecular formula = 6 × CH₂O
Molecular formula = C₆H₁₂O₆
The molecular formula of glucose is C₆H₁₂O₆.
Okay.. so I guess this is how it goes:
1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra
Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..
C or A I may be incorrect but those are what I think it is
Answer:
9.35g
Explanation:
The molarity equation establishes that:
So, we have information about molarity (2M) and volume (80 ml=0.08 l), with that, we can find the moles of solute:
The mathematical equation that establishes the relationship between molar weight, mass and moles is:
We have MW (58.44g/mole) and n (0.16 mol), and we need to find m (grams of salt needed) to solve the problem:
