Answer: Mass of diborane that would react with 7.5 mole of O2 is 70g
Explanation: The explanation is contained in the picture attached.
The total amount of water in the beaker is 0.8 Liters
calculation
convert 300 Ml in liters
that is 1 L = 1000 Ml
? = 300 Ml
by cross multiplication
1 L x300 Ml/ 1000 Ml = 0.3 Ml
total is therefore = 0.5 Ml + 0.3 Ml = 0.8 Liters
Answer: The correct answer is option D.
Explanation:
Mass of the NaCl = 225 g
Volume of the solution ,V = 0.25 L
15.4004 mol/L is the molarity of the solution. The most closest option to our answer is option D.
Conduction is particle to particle. Convection is by molecular motion. Radiation is energy that is transmitted in the form of rays or waves. C seems like the best answer.
