<span>pm stands for picometer and picometers are units which can be used to measure really tiny distances. One picometer is equal to 10^{-12} meters. We know that one centimeter is equal to 10^{-2} m so there are 10^2 cm per meter. We can change the distance d = 115 pm to units of centimeters. d = (115 pm) x (10^{-12}m / pm) x (10^2 cm / m) d = 115 x 10^{-10} cm = 1.15 x 10^{-8} cm The distance in centimeters is 1.15 x 10^{-8} cm</span>

Using water, how could you distinguish between the white solids kcl an pbcl2
Alexus [3.1K]
KCl and PbCl2 both are salts having the same white color, however, potassium salts are soluble in water while lead salts are not.
This means that KCl is soluble in water while PbCl2 is not.

So, to distinguish between them, add the same amount of each salt in a beakers containing water (each salt in a separate beaker of course), ans shake the beaker or steer it.
The salt that dissolves in water would be KCl while the salt that doesn't dissolve in water would be PbCl2.

Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa
Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.
