A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances.
Answer:
Molarity of solution = 0.9 M
Explanation:
Given data:
Moles of ZnCl₂ = 4.50 mol
Volume of solution = 200 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will convert the volume in L.
200 mL×1 L/1000 mL = 0.2L
M = 4.50 mol / 0.2 L
M = 0.9 M
Answer:
ΔG° is for ideal (fixed) or standard conditions which cannot be found at the cellular level while ΔG is dependent on the quantities of reactants and products present at a specific time
Explanation:
ΔG° is fixed value for a given reaction that indicates the direction in which the reaction will proceed in a chemical equation under ideal conditions and because conditions within a cell varies and are unlike standard conditions, ΔG° cannot predict the direction of a cellular reaction at any given time. To predict the direction of progression of a reaction within the cell, ΔG is used, which depends on the amounts of the reactants and products present at a particular time
Microwave and Radiowave are both electromagnetic
If a star is located 100 light years from Earth, the light will take 100 years to reach Earth.
I hope this helps !
