<h2>Reaction to Reach Equilibrium </h2>

Firstly the substrate concentration increases the rate of reaction also increases but at a certain limit it will stop to increase by adding up the substrate. By raising the enzyme concentration, the maximum reaction rate considerably improves.

The rate of a chemical reaction increases with respect to the substrate concentration increases. Enzymes can exceedingly promote the rate of a reaction. Enzymes convert saturated when the substrate concentration is high.

Answer: option D. 4.5 seconds.


Explanation:


The equilibrium reaction is H₂O ⇄ H₂ + O₂


The chemical equilibrium is a dynamic one. Two reactions are happening symultaneously: the forward reaction (H₂O → H₂ + O₂) ,to the right, and the reverse reaction (H₂O ← H₂ + O₂), to the left. At equilibrium both reactions have the same rate, which makes that the total, measurable quantity of reactants and products remain constant.


In the figure you see:

  • The vertical axis measures concentration.
  • The horizontal axis measures time (seconds).
  • The two blue lines, the concentrations of H₂ and O₂, become flat (reach a zero slope) between 4 and 5 seconds.
  • The red line, the concentration of H₂O, becomes flat, also, between 4 and 5 seconds.
  • Hence, the concentrations of the reactant and the products do not change after that time meaning that the reaction has reached the equilibrium at about 4.5 seconds.

If an element is more reactive, is it more likely to be found as an element or a compound?
laila [671]
It is more likely to be found as a COMPOUND, as it is more reactive, by the time we found them, they're already reacted with other elements or compounds to form new compounds.
Example is oxygen, it is very reactive, therefore we often found oxygen in water, which is H2O, in earth, instead of just pure oxygen.

How many total atoms are in 0.560 g of P2O5
ioda

Answer:

16.499 × 10∧ 21 atoms

Explanation:

Given data:

mass of P2O5= 0.560 g

number of atoms= ?

first of all we will calculate the molar mass of P2O5:

P = 2×31 g/mol = 62 g/mol

O = 5× 16 = 80 g/mol

molar mass of P2O5 = 142 g/mol

Noe we will find the moles of 0.560 g P2O5:

moles = mass / molar mass

moles = 0.560 g/ 142 g/mol

moles = 0.0039 mol

now we will find the atoms present in 0.0039 moles:

0.0039 × 6.02 × 10∧ 23 molecules

2.357 × 10∧ 21 molecules

P2O5 consist of 7 atoms:

2.357 × 10∧ 21  × 7 = 16.499 × 10∧ 21 atoms

How is the mass of a liquid substance affected after it boils.
tensa zangetsu [6.8K]
<h2>The mass of a liquid substance affected after it boils : C it stays the same</h2>

Explanation:

Matter

Anything that occupies space and has mass .

The states of matter are :

Solids

Liquids

gases

Interconversion of state of matter

Solid ------liquid -----------Gas

    (on heating )   (on heating )

  • One state can be changed in to another by changing the condition of temperature , pressure etc .
  • When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
  • This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing  the state .But it doesn't change the mass .Hence mass of substance remains the same .
  • Similarly , gas ----->  liquid -----> solid

                            (on cooling )   (on cooling )
