The statement about electronegativity that is correct is <span>D. Noble gases have the highest electronegativity values.</span>
There's no reason, it's just because the sun has a gravitational pull
Answer:
The number of waves that pass a fixed point in a given amount of time
Explanation:
The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
<h3>Why is a solution of sodium sulfate used as an antidote?</h3>
The ability of sodium sulfate to act as an antidote to barium chloride poisoning is because of the reactivity of sodium.
Sodium is a more reactive metal than barium, so it displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.
The equation of the reaction is given below:
- BaCl2 + Na2SO4 ----> BaSO4 + NaCl
Therefore, the ability of sodium sulfate to act as an antidote to barium chloride poisoning is because displaces barium in barium chloride to form sodium chloride and insoluble harmless barium sulfate.

Answer: decreases
The temperature of a gas decreases when the pressure decreases at constant volume
Explanation:
The statement of Pressure Law states that the pressure of a given mass of gas is directly proportional to its absolute temperature provided the volume is kept constant.
Mathematically, it is expressed as
P α T
P = kT
or P/T = k
Thus, the direct proportionality of temperature and pressure makes temperature of a gas decreases when the pressure decreases and increases when pressure increases.
