Oxygen and carbon are element combinations that will most likely form polyatomic ions.
The answer is that “chlorine has a greater electron affinity
than sodium does”. Sodium has a lesser electron affinity than Chlorine, which
is why it is deliberated that Chlorine is much more suitable to be existent as
an anion than sodium, due to the lack of its electron affinity.
Answer:
(4) concentrated and supersaturated
Explanation:
At 50.°C, 90g of KNO3 lies above the solubility curve [on the Regents Reference Table G]. This indicates that the solution is supersaturated, meaning it contains more solute than will naturally dissolve, and was formed when a saturated solution cooled. Furthermore, the percent concentration of this solution is 90% KNO3 making this solution concentrated. This can be calculated using the formula for mass percent concentration.
Percent Mass = <u>Mass of Solute (g)</u> x 100
Mass of Solution (g)
Answer
I'm pretty sure it would be (Insects, and microorganisms)
Explanation:
If its not correct I'm sry
Answer:
I know that the 100-mL graduated cylinders are always read to 1 decimal place.
I think for 50 mL graduated cylinders, it lets you measure volumes up to 50.0 mL to the nearest 0.1 or 0.2 mL, depending on your exact cylinder.
