Answer:
1:put these in sneaker and add water since sulphur is insoluble and the sugar will dissolve and the sand will settle obtain the sulphur
2:filter the mixture of sand and sugar solution to obtain the sand as residue and solution as filtrate
3:using an evaporating dish evaporate sugar solution to saturation not dryness to get crystals.
Chemical reaction
C2H2(g) + H2O(g) ⇄ CH2CHO(g)
a) Removing H2O(g) from the system
Remember that Le Chatelier principle states that when an equilibrium is disturbed the system will try to counteract to restate the equilibrim.
If you remove H2O(g) then the equilibrium will be displaced to the left, trying to produce more H2O(g), which means to reduce CH3CHO(g) and increasing the C2H2(g).
b) Adding CH3CHO(g)
To counteract the addition of CH3CHO(g) the system will try to regain equilibrium by producing more reactants: C2H2(g) and H2O(g)
c) Removing C2H2(g)
The system will again displace to the left, that is CH3CHO(g) will reduce and H2O(g) will increase.
d) Adding H2O(g)
The systmen will displace to the right reducing C2H2(g) and increasing CH3CHO(g).
Answer:
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool)
Explanation:
Answer:
Option (B)
Explanation:
Felsic magma refers to those magma that are comprised of more than 65% of silica content and are highly made up lighter elements like oxygen, silicon, sodium, aluminum, potassium, and are light-colored in comparison to the basic magma. Due to its high silica content, these are high viscosity magma and flows at a much slower rate. The felsic magma crystallizes at a relatively low-temperature rocks and the rocks that are formed from this type of magma have a specific gravity of less than 3.
Thus, the correct answer is option (B).
Answer:
Enzymes affected the speed of the reaction and the energy required to start the reaction.
