Answer:
What do cuticles do for land plants that was not necessary for ancestors that lived in water? Cuticles help prevent water loss. ... The next groups of land plants to evolve were ferns, which could grow bigger and taller because they could transport water and food.
Explanation:
Answer:
Pb(NO₃)₂ (aq) + 2NaCl (aq) → PbCl₂ (s) ↓ + 2NaNO₃ (aq)
Explanation:
The reactants are:
Lead(II) nitrate → Pb(NO₃)₂ (aq)
Sodium chloride → NaCl (aq)
The products are:
Lead(II) chloride → PbCl₂ (s)
Sodium nitrate → NaNO₃ (aq)
Salts form nitrate are soluble. The chloride makes a precipitate with the Pb²⁺. The chemical equation for this reaction is:
Pb(NO₃)₂ (aq) + 2NaCl (aq) → PbCl₂ (s) ↓ + 2NaNO₃ (aq)
It would be a ehtanol plant
Answer:
0.0445 M is the initial concentration of sulfurous acid.
Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is NaOH.
We are given:

Putting values in above equation, we get:


0.0445 M is the initial concentration of sulfurous acid.
