There are 84 metal elements
Answer:
The rate of a chemical reaction is directly proportional to the concentration. The rate of a chemical reaction increases as the substrate concentration increases and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.
Explanation:
The rate of a chemical reaction is directly proportional to the concentration.
The reaction rate increases with increasing substrate concentration, but levels off at a much lower rate. By increasing the enzyme concentration, the maximum reaction rate greatly increases.
Generally, the rate of a chemical reaction increases as the substrate concentration increases, and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.
Answer:
P₂ = 220.56KPa
Explanation:
Boyles Law P ∝ 1/V => Inverse relationship => Decreasing Volume => Increasing Pressure.
P₁ = 198 KPa P₂ = ?
V₁ = 15.35 Liters V₂ = 13.78 Liters
P₁V₁ = P₂V₂ => P₂ = P₁(V₁/V₂) = 198KPa(15.35 L/ 13.78L) = 220.6KPa
Force is a strength or energy as an attribute or physical action or movement, motion is the action or process of moving or being moved
Answer:
A. The accepted model of the atom was changed.
Explanation:
Thomson described an atom that has the protons uniformly distributed within a circular atom with the electrons embedded . However, it cannot explain the emission of electrons from the surfaces of metals like photoelectric emission. it does not explain how the particle of the atom contribute significantly to the entire mass of an atom
