Answer:
A. The neutrons and electrons are in the wrong place.
Explanation:
The atom's nucleus contains both protons and neutrons, whilst the electrons are arranged in shells around the nucleus.
Lewis Structure:
H -- O -- H (bent, Oxygen has 2 lone pairs)
Percent Composition
Hydrogen percent composition = [ 2 * (Hydrogen mass) ] / [Total mass of H2O]
Oxygen percent composition = [Oxygen mass] / [Total mass of H2O]
dose this make any sense...??
Answer:
-Theres 20 amino acids in the human body
-The least number of amino acids in a polypeptide are 10
Explanation:
Answer:
C) As a gas is heated, the pressure decreases.
Explanation:
From the choices given, the statement that "as a gas is heated, the pressure decreases is false".
When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.
- Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
- When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
- Thus, they take up even more space allowing volume to increase appreciably.
