HNO3 and H2SO4 are Arrhenius acids which will increase the concentration of H+ when dissolved in water.
KOH and Ca(OH)2 are Arrhenius bases that increase the concentration of OH- when dissociated in water.
The law of conservation of mass dictates that the total mass of reactants must be equal to the total mass of the products. Thus:
mass(MgO) = mass(Mg) + mass(O)
mass(MgO) = 24 + 16
mass(MgO) = 40 g
The third option is correct.
Actually, it could indeed be the independent variable.
Answer:
C) condensation of steam inside.
Explanation:
Steam only condenses on a surface when the temperature of that surface is less than the saturation temperature for the pressure at which the steam is found. During this process the water molecule releases energy in the form of heat, in this case the water contained in the can brings a very high temperature causing the temperature of the cold water bath to rise abruptly thus releasing energy which makes the can crushed.
