A 40 g garden soil was air-dried and allowed to pass through a sieve of 2mm. It was found that it contains 12g of sand,2g of water and 10g of silt. a) Calculate the percentage of
sand in the soil.
(b) Calculate the percentage of
clay.
(c) Calculate the percentage of
silt
d) Using
the textual triangle,
determine the soil texture.​

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
