Answer:
2.92 mol
Explanation:
Step 1: Write the balanced equation
2 B(s) + 6 HCI(aq) ⇒ 2 BCl₃(aq) + 3 H₂(g)
Step 2: Establish the appropriate molar ratio
The molar ratio of hydrochloric acid to boron chloride is 6:2.
Step 3: Calculate the moles of boron chloride produced from 8.752 moles of hydrochloric acid
Molar mass H₂SO₄ = 98.0 g/mol
Volume = 1.290 L
number of moles:
153.3 / 98 => 1.564 moles
M = n / V
M = 1.564 / 1.290
M = 1.212 mol/L

Answer:
Sodium + Water = Sodium Hydroxide + Dihydrogen
Explanation:
eaction of sodium with water
Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
