Answer: 4.15234 m
512 g H2O * = 0.512 kg H2O
Nitric Acid: HNO3 = 1.008 + 14.007 + 3(15.999) = 63.012 g/mol
H = 1.008 g/mol
N = 14.007 g/mol
O3 = 3*15.999
134 g HNO₃ * = 2.126 mol
m = = 4.15234 m
Mass of Magnesium nitrate formed : 731.86 g
<h3>Further explanation</h3>A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
Mg + 2AgNO₃ → Mg(NO₃)₂ + 2 Ag
moles of silver nitrate, AgNO₃ = 9.87
mole ratio AgNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :
mass of Mg(NO₃)₂(MW=148,3 g/mol) :
Answer:
The given statement is false.
Explanation:
Displacement is a vector quantity which represent shortest distance form initial position to final position.
Velocity of an object is defined as ratio of displacement of object to that of the time taken by object to move from its initial position to final position.
In displacement vs time graph the slope of the graph represent the velocity. Whereas slope of velocity vs time graph gives acceleration.
