Answer:
V₂ = 70.80 L
Explanation:
Given data:
Initial volume of He = 45 L
Initial temperature = 250 °C
Final temperature = 550 °C
Final volume = ?
Solution:
Initial temperature = 250 °C (250+273.15 K= 523.15 K)
Final temperature = 550 °C (550 + 273.15 k= 823.15 K)
According to Charles Law.,
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 L × 823.15 K / 523.15 K
V₂ = 37041.75 L.K / 523.15 K
V₂ = 70.80 L
Negatively charged ions move to the positive electrode during electrolysis. They lose electrons and are oxidised . The substance that is broken down is called the electrolyte.
White phosphorus melts and then vaporizes at high temperatures. The gas effuses at a rate that is 0.404 times that of neon in the same apparatus under the same conditions-There are 4 atoms of P in the molecule
Explanation:
Ar=30,97g/mol
/==0,404
0,404=
=20,18/30,97*x
X=20,18/30,97*0,163
X=4
There are 4 atoms of P in the molecule

Answer:
Polymers are long chain molecules that occur naturally in living things and can also be made by chemical processes in industry. Plastics are polymers, so polymers can be extremely useful.
Explanation:
Answer:
Unbalanced
Explanation:
There is going to be 4 Iron and 4 Oxygen as the end result if I am remembering how to do this correctly so there for 2Fe +O₂→ Fe₃O₄ is unbalanced
