Pls assist if you can.Reasons why hydrogen was chosen as a standard reference to other elements

Chemistry
1 answer:
MrMuchimi3 years ago
4 0

Answer:

See below  

Step-by-step explanation:

  • Hydrogen either reacts with or is formed by reactions with many other elements, so chemists could use it directly to determine their relative masses.
  • Hydrogen has the smallest atomic mass, so it was convenient to give H a relative atomic mass of 1 and assign those of other elements as multiples of this number.

The O = 16 scale became the standard in 1903 and carbon-12 was chosen in 1961.

If a gas in a closed container is pressurized from 15.0 atmospheres to 16.0
Yuki888 [10]

Answer:

T₂ = 317.87 K

Explanation:

Given data:

Initial pressure = 15 atm

Final pressure = 16 atm

Initial temperature = 298 K

Final temperature = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

15 atm / 298K = 16 atm/T₂

T₂ = 16atm × 298 K / 15 atm

T₂ = 4768 atm. K / 15 atm

T₂ = 317.87 K

How many moles of ions are there in 3 moles of calcium chloride?
klemol [59]

Answer:

9 moles of ions

Explanation:

Our compound is: CaCl₂(s)

We dissociate it:

CaCl₂(aq) → Ca²⁺ (aq) + 2Cl⁻(aq)

Per 1 mol of chloride, we have 1 mol of calcium cation and 2moles of chlorides, so in total we have 3 moles of ions.

Therefore in 3 moles of chloride, we would have 9 moles of ions (3 . 3)
