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.

conduction is the transfer of energy by the movement of currents(it is true)
Answer : The specific heat of the metal is, 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water = 
= mass of metal = 50.0 g
= mass of water = 125 g
= final temperature of mixture = 
= initial temperature of metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
![(50.0g)\times c_1\times (29.3-115.0)^oC=-[(125g)\times 4.18J/g^oC\times (29.3-25.6)^oC]](https://tex.z-dn.net/?f=%2850.0g%29%5Ctimes%20c_1%5Ctimes%20%2829.3-115.0%29%5EoC%3D-%5B%28125g%29%5Ctimes%204.18J%2Fg%5EoC%5Ctimes%20%2829.3-25.6%29%5EoC%5D)
Therefore, the specific heat of the metal is,
Answer don't know at all but i will find out by tomorrow
Explanation: sorry
Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
