Answer : The ratio of hydrogen and oxygen in water is, (2:1)

Explanation :

As we know that the chemical formula of water is, H_2O.

In H_2O, there are 2 atoms of hydrogen and 1 atom of oxygen.

As we are given that the volume of water is, 2 L. So, there is no matter what is the volume of water that means there is no role of volume of water.

The ratio of hydrogen and oxygen in water is, (2:1)

Thus, in 2 L volume of water, the ratio of hydrogen and oxygen in water is also same that is, (2:1)

State relationship between the level of dissolved oxygen and water temperature
Artemon [7]
More dissolved oxygen is present in water with a lower temperature compared to water with a higher temperature. The reason for this inverse relationship between dissolved oxygen and temperature is that the solubility of a gas in a liquid is an equilibrium phenomenon.

A metal (M) forms an oxide with the formula MO. If the oxide contains 7.17 % O by mass, what is the identity of the metal?
Nataly_w [17]

The metal is lead, Pb.

One unit of the oxide contains one atom of O (16.00 u).

∴ Mass of oxide = 16.00 u O × (100 u MO/7.17 u O) = 223.15 u MO

Mass of M = mass of MO – mass of O = 223.15 u -16.00 u = 207.2 u

The only element with an atomic mass of 207.2 u is lead (Pb) and the formula of the oxide is PbO.

4.00 moles of CU(CN)2<br><br>Find the number of grams ​
UNO [17]

Hey there!

Cu(CN)₂

Find the molar mass.

Cu: 1 x 63.546 = 63.546

C: 2 x 12.01 = 24.02

N: 2 x 14.07 = 28.14

-----------------------------------

                      115.706 grams

The mass of one mole of Cu(CN)₂ is 115.706 grams.

We have 4 moles.

115.706 x 4 = 463

4.00 moles of Cu(CN)₂ has a mass of 463 grams.

Hope this helps!
