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.
<span>The question is asking for the number of valence electron that are available fo bonding in bromine. Bromine belongs the group 7 of the periodic table, thus it has seven electrons in its outermost shell. At times, all these seven valence electrons can be involved in a chemical bonding in order to form an octet structure. Also, bromine can form a single covalent bond with other elements during chemical reactions. </span>
Answer : the system the scientist is studying consists of the car, the humid garage and Air
Explanation:
In order to find the system, the scientist is studying, we need to take a look at what happens to different parts of a car in a humid garage.
Majority parts of the car are made of iron. In humid garage, there is moisture ( Water vapors) in the air. When iron comes in contact with oxygen from air and moisture, corrosion of iron begins. Corrosion is a reaction of iron with oxygen in presence of water which produces iron oxide which is known as rust.
Therefore we can write down the equation for the reaction that is occurring in a humid garage
Iron ( Parts of car) + Water ( humid garage) + Air ( oxygen) ⇒ Iron oxide ( Rust)
Therefore the system the scientist is studying consists of the car, the humid garage and Air

Answer: Concentration of at equilibrium = 0.08 M
Concentration of at equilibrium =0.08 M
Concentration of = 0.64M
Explanation:
Moles of = 4.00 mole
Volume of solution = 5.00 L
Initial concentration of =
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the given chemical reaction:
Initial conc. 0.8 M 0 M 0 M
At eqm. conc. (0.8-2x) M (x) M (x) M
The expression for is written as:
Concentration of at equilibrium = x M = 0.08 M
Concentration of at equilibrium = x M = 0.08 M
Concentration of = (0.8-2x) =
