Well the atomic number for the boron atom is 5
The answer would possible be letter a
Surface runoff, its quite obvious in the picture
Answer:
e. BaSO4 and KCI.
Explanation:
Hello there!
In this case, given the reactants side:
It is possible to realize that after the reaction takes place barium replaces potassium and therefore barium sulfate and potassium chloride are formed:
Therefore, the products turn out to be e. BaSO4 and KCI.

Answer : The final temperature of gas will be, 149 K
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = 1.55 L
= final volume of gas = 753 ml = 0.753 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above formula, we get the final temperature of the gas.
Therefore, the final temperature of gas will be, 149 K
