Answer:
H2SO4 (sulphuric acid) is considered a strong acid because it's H+ ions completely dissociates or ionizes in a water. When reacted with phenolphthalein is colourless because phenolphthalein doesn't react with acids, only strong bases and when reacted with methyl orange, it changes from orange to red.
Explanation:
Answer:
Chemistry reactions are used in art for the following processes;
1) Analog photography
The photographic paper used in analog photography react when exposed to light such that the image on the film stains the photopaper
A series of chemicals are further used to develop the images now carried on the paper and water is used to rinse of the chemicals after the other chemical processes are complete
The photopaper, now bearing the developed photo is hung for it to be dried
2) Paint used for painting consists of several chemicals, including, minerals that serve as pigment, oils that serve as carrying agent, a thinner to prevent the paint from turning to solid
An artist therefore combines different chemicals for a given paint task
3) In the sculpting process
An original sculpture is produced by the artist with the aid of clay or plaster, from the original sculpture, on which wax coatings and chemicals are used to make a replica mold.
Copies of the sculpture can then be made by pouring material into the mold
Explanation:
Answer:
A), C), and E)
Explanation:
We need to use the Le Chatelier´s principle to answer this question as follows:
A) Increasing the size of the reaction vessel has the effect of decreasing pressure, so the equilibrium will shif to the side that has greater pressure which in this case is the products, so we the number of moles of CS2 will increase.
B) If we add more product Cl2 to the system it will shift to the reactants to counteract the change in the equilibrium; therefore, some CS2 will be consumed.
C) If we add reactant S2Cl2 to the system it will shift to the product side therby increasing the number of moles of CS2
D) The reaction is endothermic so it will shift to the reactant side.
E) Adding more reactant CCl4 will shift the equilibrium to the right side favoring more CS2
