A sample of gas occupies 115.9 mL at -206.6°C. What volume does the sample occupy at 175.9 °C?
1 answer:
Charles law gives the relationship between volume of gas and temperature.
It states that for a fixed amount of gas at constant pressure, volume of gas is directly proportional to the temperature.
where V - volume and T - temperature and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin , -206.6 °C + 273.15 = 66.55 K
T2 - 175.9 °C + 273.15 = 449.05 K
substituting the values in the equation
V = 782 mL
the new volume is 782 mL

Answer:
D.
Explanation:
Hello!
In this case, for the given set of chemical reactions, it is possible to infer that D. is a categorized as redox due to the following:
Since both chlorine and bromine remain as diatomic gases, their oxidation states in such a form is 0, but as anions with lithium cations they have a charge of - according to the following reaction and half-reactions:
Unlike the other reactions whereas no change in the oxidation states is evidenced.
