Answer: Option (1) is the correct answer.
Explanation:
Compounds are the substances which contain two or more different elements.
Similarly, water is a compound as it is made up when two hydrogen atoms combine with one oxygen atom. Compounds can be broken down with the help of chemical reactions.
Hence, the statement water can be broken down by chemical means explains why water is classified as a compound.
the electrons charge is negative

Answer:
2.04 atm
Explanation:
The pressure of the gas can be found by using the equation of state for an ideal gas:
where
p is the gas pressure
V is the gas volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For this gas we have:
n = 0.316 mol (moles)
V = 4.00 L (volume)
T = 315 K (absolute temperature)
(gas constant)
Therefore, the gas pressure is
Answer:
Macromolecule is the correct answer.
Explanation:
- A macromolecule is a complex and big molecule that is formed by joining of small subunits.
- Nucleic acids, protein, Carbohydrate, and lipids are examples of the macromolecule.
- Nucleic acids are the most essential macromolecules as they store genetic information.
- Macromolecules are an essential component of the cell that is required for the growth and proper functioning of living organisms.
