I think the correct answer from the choices listed above is option B. The following reaction does not proceed to form a product: H2O + Au---> no reaction because gold has a lower activity than hydrogen and cannot replace it. Hope this answers the question.
Answer:
C
Explanation:
Temperature is the measure of "hotness" of a system. When temperature increases, the kinetic energy of the particles increase. So they will collide with greater energy per collision.
Answer:
0.264 mol/L
Explanation:
Data obtained from the question includes:
Volume = 5.74L
Mass of FeCl3 = 246 g
Molarity =?
Next, we shall determine the number of mole in 246g of FeCl3.
This is illustrated below:
Mass of FeCl3 = 246g
Molar mass of FeCl3 = 56 + (35.5x3) = 162.5g/mol
Number of mole of FeCl3 =..?
Mole = Mass /Molar Mass
Number of mole of FeCl3 = 246/162.5
Number of mole of FeCl3 = 1.514 mol
Now, we can obtain the molarity of the solution as follow:
Molarity = mole /Volume
Volume = 5.74L
Mole of FeCl3 = 1.514 mol
Molarity = 1.514/5.74
Molarity = 0.264 mol/L
Answer:
A. Chromosome
Explanation:
Chromosomes carry the genetic info, and the nucleus stores it.
