Answer:
Atomic elements exist with a single atom as their basic unit.
H, F, and P are some examples of atomic elements.
H2, F2, and P4 are some examples of molecular elements.
Molecular elements have more than one atom in their basic unit.
Explanation:
Atomic element exists as the smallest particle of an element that can take part in a chemical reaction. They exist with a single atom as their basic unit. The atomic number of an element is the number of protons present in the atomic nucleus of the element. Atomic elements are usually monoatomic such as H, F and P.
Molecular elements are the smallest particle that are capable of independent existence and still retains the chemical properties of those substances. They are capable of independent existence because they are diatomic. The combination of atoms of the same type produces a molecule of an element such as H₂, F₂, and P₂.
NaCI4: Sodium perchlorate
SO3: SULFITE ION
Assume that the water vapor is an ideal gas. So,
PV = nRT
For conversion, 760 mmHg = 101325 Pa and 1,000 L = 1 m³
(187.5 mmHg)(101325 Pa/760 mmHg)(5 L)(1 m³/1,000 L) = n(8.314 m³Pa/molK)(65+273 K)
Solving for n,
n = 0.0445 mole water
Since the molar mass of water is 18 g/mol,
Mass of water vaporized = 0.0445*18 = 0.8 g water vaporized
Hence,
Percentage of water vaporized = 0.8/1.2 * 100 =<em> 66.7%</em>
How? Well radiation can be used to improve everyday life. Nuclear energy can be used in medicine and as tools of treatment, especially for cancer, and trace the movement of atoms in biological systems.
Hope i got the answer correct....
