Answer:
When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.
Answer:
3.011×0²³ atoms of Ar
Explanation:
To find no.of atoms of Ar gas in 10.2 L at STP.
At STP 1 mole of a gas occupies 22.4 L and contains 6.022×10²³ atoms/molecules or ions.
At STP
22.4 L contains 1 mole Ar t
10.2 L contains (10.2÷22.4)×1 Ar
mole Ar contains
×6.022×10²³
=3.011×0²³ atoms of Ar
Answer:
No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.
