The number of protons would be equivalent to the number of electrons if the net charge on the atom is 0.
Answer:
This paper is impregnated with iodide ions and starch and will turn black if treated with an oxidizing agent (e.g. HOCl) which oxidizes the iodide ions
Explanation: hope this helps :)
Answer:
77 L of water can be made.
Explanation:
Molar mass of
= 32 g/mol
So, 55 g of
=
mol of
= 1.72 mol of
As hydrogen is present in excess amount therefore
is the limiting reagent.
According to balanced equation, 1 mol of
produces 2 mol of
.
So, 1.72 mol of
produce
mol of
or 3.44 mol of
.
Let's assume
gas behaves ideally at STP.
Then,
, where P, V, n, R and T represents pressure, volume, no. of moles, gas constant and temperature in kelvin scale respectively.
At STP, pressure is 1 atm and T is 273 K.
Here,
= 3.44 mol and R = 0.0821 L.atm/(mol.K)
So, 

Option (b) is correct.
