Answer:
62.36 g
Explanation:
AgNO3 + H2SO4 - > Ag2SO4 + HNO3
The balanced equation is given as;
2AgNO3 + H2SO4 → Ag2SO4 + 2HNO3
From the equation;
2 mol of AgNO3 reacts with 1 mol of H2SO4
if 0.200 moles of AgNO3 react with 0.155 moles of H2SO4
The limiting reactant us AgNO3 as it determines the amount of products to be formed.
2 mol of AgNO3 produces 1 mol of Ag2SO4
0.2 mol of AgNO3 would produce x mol of Ag2SO4
Solving for x;
2 = 2
0.2 = x
x =0.2 * 2/ 2 = 0.2 mol
Converting moles to mass;
Mass = Number of Moles * Molar mass
Mass = 0.2 mol * 311.8 g/mol
Mass = 62.36 g
Answer:
Its the temperature at which the molecules of a matter especially a liquid attain higher kinetic energy and the rate of collision becomes increased
Explanation:
The closer to the top the metal is in the list, the more active the metal is and the stronger a reducing agent the metal is. When two different metals are involved in a redox reaction, the metal higher in the list will be oxidized and give up electrons that will reduce the cation of the less active metal.
The distinguish between each pair of compounds using high- resolution mass spectrometry by the exact mass rather than nominal mass are utilizes to measure the compound.
The mass spectrometry is involves the following steps :
- The ionization
- acceleration
- deflection
- detection
Mass spectrometry is the analytical method useful for the calculating the mass to charge ratio ( m / z ). the mass spectrometry is based on the newton's second law and the momentum.
Thus, the mass spectroscopy is method to measure the molecular mass of the compound and indirectly helps examine the isotopes and based on the newton's second law .
