$ag_{(aq)} + cl_{(aq)} \longrightarrow agcl_{(s)}$
product(s)
coefficients
states of matter
charges

Explanation:

First Question (Solubility Factor)

To determine the solubility factor:

• Pressure affects gas solubility more, not particle speed increase.
• Polarity relates to "like dissolves like," not particle speed.
• Covalent bonding is a type of chemical bond, not a solubility factor affecting particle speed.
• Temperature increase makes particles move faster (kinetic energy rises), increasing solubility for many solutes (especially solids in liquids, generally). So temperature is the factor.

Analyze the net ionic equation \( Ag_{(aq)} + Cl_{(aq)}
ightarrow AgCl_{(s)} \):

• Product(s): \( AgCl_{(s)} \) is a product, so not missing.
• Coefficients: The equation has 1 \( Ag \), 1 \( Cl \), and 1 \( AgCl \), so coefficients (1s, implied) are not missing.
• States of matter: \( (aq) \) and \( (s) \) are included, so not missing.
• Charges: \( Ag_{(aq)} \) should have a charge (like \( Ag^+_{(aq)} \)) and \( Cl_{(aq)} \) should have \( Cl^-_{(aq)} \); the equation lacks ion charges.
