Answer:
radio waves are the sound waves that are produces by a radio
Explanation:
Answer:
The answer to your question is: 0.3 moles of AgNO₃
Explanation:
1.0 L sample
0.1 mol of NaCl
0.1 mol of CaCl₂
AgNO₃ = ? moles
Reactions
NaCl + AgNO₃ ⇒ AgCl + NaNO₃
Then 1 NaCl mol --------------- 1 AgNO₃
0.1 mol -------------- x
x = 0.1 moles of AgNO₃ needed
CaCl₂ + 2 AgNO₃ ⇒ 2 AgCl + Ca(NO₃)₂
Then 1 mol of CaCl₂ ------------- 2 moles of AgNO₃
0.1 mol ------------- x
x = 0.2 moles of AgNO₃
Total moles of AgNO₃ = 0.1 + 0.2 = 0.3
The simple principle for solute dissolution in a particular solvent is "like dissolves like". In the case of water, a solute will dissolve if it is polar. This is because water is a polar solvent. A polar substance is one which has particles that have a net charge on them. This net charge produces forces of attraction. When a polar solute is added to water, the water molecules are attracted to the solute particles and they attach to them. After attaching to the water molecules, the solute particles are dispersed throughout the water. Therefore, the answer is molecules or ions of a solute spread throughout the water molecules<span>.</span>
