Explanation:

If two gases are present in a container, the total pressure int in the container is equal to the sum of the partial pressure of each individual gas. This is given by Dalton and it is known as Dalton's Law of Partial Pressure. The combined pressure of the two gases

spayn [35]

Answer:

C₅ H₁₂ O

Explanation:

44 g of CO₂ contains 12 g of C

30.2 g of CO₂ will contain 12 x 30.2 / 44 = 8.236 g of C .

18 g of H₂O contains 2 g of hydrogen

14.8 g of H₂0 will contain 1.644 g of  H .

total compound = 12.1 out of which 8.236 g is C and 1.644 g is H , rest will be O

gram of O = 2.22

moles of C, O, H in the given compound =  8.236 / 12 , 2.22 / 16 , 1.644 / 1

= .6863 , .13875 , 1.644

ratio of their moles = 4.946 : 1 : 11.84

rounding off to digits

ratio = 5 : 1 : 12

empirical formula = C₅ H₁₂ O

How much water, in grams, can be made from 1.84 × 1024 hydrogen molecules?
Ilya [14]

Answer:

55.0g water can be made

Explanation:

To solve this question, we must convert the molecules of H2 to moles using Avogadro's constant. With the moles, and the reaction:

H2 + 1/2O2 → H2O

We can find the moles of H2O = Moles H2 and its mass of using molar mass of water -H2O = 18.01g/mol-

<em>Moles H2 = Moles H2O:</em>

1.84x10²⁴ molecules * (1mol / 6.022x10²³ molecules) = 3.055 moles H2O

<em>Mass:</em>

3.055 moles H2O * (18.01g / mol) = 55.0g water can be made

Complete the sentence. The lower the hydrogen ion concentration, the ______ the pH.
enyata [817]
The answer is higher, because the more H+ ions there are, the more acidic the solution is, and the lower the ph it will have.
