Moles=concentration x volume. 1.5/1000 multiply 0.450 = 6.75x10^-4
To find the mass of fecl3, we have the formula, mass=moles x molar mass. 6.75x10^-4 x (55.8+35.5 x 3). = 0.1096g
Not sure tho if i did it right
Answer:
Interacting with animals has been shown to decrease levels of cortisol (a stress-related hormone) and lower blood pressure. Other studies have found that animals can reduce loneliness, increase feelings of social support, and boost your mood.
Explanation:
Answer:
(A)
Solubility will increase.
(B)
Solubility will decrease.
(C)
Solubility will decrease.
Explanation:
a) According to Le Chatelier's Principle when a change is introduced in a reaction system at equilibrium, the system responds by the reaction shifting in the direction to counter the change introduced.
When the change introduced is addition of acid, some
are consumed due to it and the system would respond by reaction shifting towards creation of more
in the system by increased dissolution. Thus solubility increase.
(b) When
are added, the reaction shifts to counter the change introduced of increased
by shifting to side that decreases the increased
. That happens by reaction shifting towards some
precipitating back. Hence solubility decreases.
(c) The change introduced is addition of
which will be countered by reaction shifting to side that decreases increased
, which happens by some
precipitating back. Hence solubility decreases.
The alchemists were the first chemists, but they were also mixing chemicals, they believed that magic would help with their experiments.but it didn't. but their experiments of the science of chemistry did.<em><u></u></em>
