The answer to this would be helium
Answer:
424 °C
Explanation:
If all other variables are held constant, the missing temperature can be found using the Charles' Law equation:
V₁ / T₁ = V₂ / T₂
In this equation, "V₁" and "T₁" represent the initial volume and temperature. "V₂" and "T₂" represent the final volume and temperature. You can plug the given values into the equation and simplify to find the final temperature.
V₁ = 435 mL V₂ = 842 mL
T₁ = 219 °C T₂ = ? °C
V₁ / T₁ = V₂ / T₂ <----- Charles' Law
435 mL / 219 °C = 842 mL / T₂ <----- Insert values
1.9863 = 842 mL / T₂ <----- Simplify left side
(1.9863) x T₂ = 842 mL <----- Multiply both sides by T₂
T₂ = 424 °C <----- Divide both sides by 1.9863
Water’s chemical formula is H2O
One atom of oxygen bonded to two attached atoms of hydrogen.
The hydrogen atoms are to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogens reside and a negative charge on the other side, where the oxygen atom resides. This separation
of charge on opposite ends of the molecule is called polarity
I hope this right and can help you!
Answer: 0.24 moles
Explanation:
Molecular Mass of NaCl (23 + 35.5) = 58.5g
58.5g of Sodium Chloride -------> 1 mole of NaCl
∴ 13.8g of Sodium Chloride ------> 1 ÷58.5 x 13.8 = 0.2358974 ≈ 0.24moles
