Answer:
tha mass of magnesium nitrate is 592g
Explanation:
from a balanced chemical equation
2HNO3 + Mg(OH)2→ Mg(NO3)2 + 2H2O
2 mol of nitric acid is equivalent to 1 mol of magnesium nitrate. then 8 mol of nitric acid will be equivalent to 4 mol of magnesium nitrate.
260 miles with 12 gallons of gas
260 miles/12 gallons=21.6667 miles/1 gallon
286 miles/(21.6667 miles/1 gallon)=13.2 gallons of gas

Modern Agriculture - The agricultural practices with modern technique like Fertilizers, Innovative hybrid seed, and utilization of machine call modern Agriculture.
Advantages -
Feeding to the population without scarcity of food grains.
Optimum Utilization of land (Crop intensity more then 300%)
Increased production of food grain.
Global Market - even our mangoes available at US and we are getting California apple too.
Due to factories and Machine use this industry is growing to and empowering good employment.
I hope this helps you :)
Answer:
t = 50,000s
Explanation:
Reaction is second order.
Initial conc. [A]o = 0.020 M
Rate constant = 1.0x10-3 M-1s-1
Final conc. [A] = 0.010M
Time = ?
1 / [A] = kt + 1 / [A]o
Substituting the values;
1 / 0.010 = 1.0x10-3 * t + (1/0.020)
100 - 50 = 1.0x10-3 * t
t = 50 / (1.0x10-3)
t = 50,000s
