Val warms up some soup on the stove. assuming no phase change has occurred, what effect does warming have on the soup?

The particles of the soup has increased kinetic energy and thus move around more randomly, colliding more often with each other. There is also an increase in the temperature of the soup.

When heat is added or removed from substances, it results in an increase or decrease in the temperature of that substance.

Val warms up some soup on the stove, he adds heat energy to the soup particles resulting in a temperature increase.

The increase in temperature occurs because when is added to a substance, the particles of that substance acquire energy in the form of kinetic energy. This increase in kinetic energy of the particles cause them to move faster and collide more often with each other.

Since temperature is a measure of the average kinetic energy of the particles of a substance, the temperature of that substance increases with increase in the kinetic energy of its particles.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
