Answer:
Filtration and evaporation
Explanation:
A mixture of sand, pink sugar and water can be separated by filtration and evaporation.
The pink sugar is already dissolved in the water but the sand remains undissolved in the water hence it can be filtered off. The filtrate now contains the sugar.
The sugar is obtained from the filtrate by evaporation of the solution to yield the solid pink sugar and steam which can be condensed again to give liquid water.
For # 2 1.456• 205 is 1.251 and 2.456 +205 is 298.48
Answer; relative elements are most reactive elements and compounds may ignite spontaneously or explosively. They generally burn in water as well as the oxygen in the air
Explanation:
This reaction is known as esterification, esterification is done by reacting carboxylic acid with alcohol in the presence of acid. Below reactions depicts the formation of ester (right reaction) and a formation of salt (left) this salt formed is insoluble in ethanol, hence, white precipitates are observed.
When dealing with compounds and their names, it helps to know the prefixes of some of the common compounds. For instance,
Mono- = 1
Di- = 2
Tri- = 3
Tetra- = 4
Penta- = 5
Hexa- = 6
And the list goes on.
However we are dealing with Arsenic
Hexabromide:
That means we have 1 Arsenic with 6 Bromides:
