The correct answer here is C. Dew forms on the grass.

Water is a polar substance, which means it has many unique properties. One of which, is its ability to adhere and cohere to surfaces and substances. This particular question is asking about the cohesive properties of water, meaning it’s ability to stick to itself (through bonding.) The only answer choice that represents a situation where water is linking up with other molecules of water are dew drops. The water comes together using cohesion to form the drop and hen the water’s high surface tension properties meet the dew drop’s shape. The other answer choices describe alternate processes like: freezing, melting, and evaporation, respectively.

I hope this helps! :)

1. 32.5grams of NaOH (sodium hydroxide) reacts an excess of CO2 (carbon dioxide).
SOVA2 [1]

a. 43.1 g

b. 38.2%

<h3>Further explanation</h3>

Given

32.5 grams of NaOH

Required

The theoretical yield of Na₂CO₃

The percent yield

Solution

Reaction

2NaOH(s) + CO₂(g) → Na₂CO₃(s) + H₂O(l)

mol NaOH :

= mass : MW

= 32.5 : 40 g/mol

= 0.8125

mol Na₂CO₃ from the equation :

= 1/2 x mol NaOH

= 1/2 x 0.8125

= 0.40625

a.

Mass Na₂CO₃ :

= mol x MW Na₂CO₃

= 0.40625 x 106 g/mol

= 43.0625≈43.1 g

b. % yield = (actual/theoretical) x 100%

%yield = 16.45/43.1 x 1005

%yield = 38.17%≈38.2%
