Making observations is the first step in the scientific method. Why don't scientists stop with the first step when creating an e

xperiment? *
14 points
A. Scientists don't stop with the first step of their experiment because they don't think that just using their observations is a very good place to start to prove their hypothesis.
B. Scientists don't stop with the first step of their experiment because they not only want to observe but they want to test their observations to be sure they are correct.
C. Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
D. Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them.

Sulfur oxides Carbon monoxides Chlorofluorocarbons (CFCs)Nitrates are responsible for the hole in the ozone layer.
svp [43]
The best answer for the question above would be the chloroflourocarbons or the CFCs. These chloroflourocarbons or CFCs are the ones responsible for the depletion of the ozone - which leads to leaving a hole in its layer. These gases eat out the ozone layer and allows harmful UV rays of the sun to come in the Earth.

Why is it suggested you use weighing paper or a watch glass instead of filter paper on which to allow a sample to dry? please gi
snow_lady [41]
The suggestion is to prevent a puddle of the liquid present in the sample from forming or from it leaking on to the surface on which it is placed. For example, if precipitates of a solid are removed from water and then placed on filter paper to dry, the water will soak into the filter paper and then leak on to the counter on which it is placed. If this precipitate were placed in a watch glass or weighing paper, the water would only evaporate and would not contaminate the sample.

The molar solubility of pbi2 is 1.5 103 m.
Vsevolod [243]

Answer: -

Concentration of PbI₂ = 1.5 x 10⁻³ M

PbI₂ dissociates in water as

PbI₂ ⇄ Pb²⁺ + 2 I⁻

So PbI₂ releases two times the amount of I⁻ as it's own concentration when saturated.

Thus the molar concentration of iodide ion in a saturated PbI₂ solution = [ I⁻] =

= 1.5 x 10⁻³ x 2 M

= 3 x 10⁻³ M

PbI₂ releases the same amount of Pb²⁺ as it's own concentration when saturated.

[Pb²⁺] = 1.5 x 10⁻³ M

So solubility product for PbI₂

Ksp = [Pb²⁺] x [ I⁻]²

=1.5 x 10⁻³ x (3 x 10⁻³)²

= 4.5 x 10⁻⁹
