Answer:
B. (Linear graph with positive slope)
Explanation:
The picture above showing that
1. T2 is higher than T1
2. V2 is higher than V2
From this, we can conclude that the relationship for temperature (T) and volume(V) is positive. That means a higher temperature will result in a higher volume.
Since the relationship positive, the graph will have a positive slope. We can't prove if the graph should be linear or exponential since we don't have the exact number of the experiment.
Answer:
Zinc sulfide- more soluble in 0.10 M hydrochloric acid solution
Silver chloride- less soluble in 0.10 M hydrochloric acid solution
Lead iodide- same solubility in 0.10 M hydrochloric acid solution as in pure water
Silver hydroxide- same solubility in 0.10 M hydrochloric acid solution as in pure water
Explanation:
Solubility refers to the amount of a substance that dissolves in 1 dm^3 of solvent. Several factors influence the dissolution of solutes in a given solvent. Some substances dissolves at a low pH (in acid solutions) while other dissolve at a low pH (in basic solutions).
For Silver chloride, its solubility decreases in 0.10 M hydrochloric acid solution because of common ion effect when compared to its solubility in pure water.
Answer:
This chemical reaction is a combustion.
n = 1.8mol
Explanation:
The ratio of oxygen to water is 13 to 10
The ratio of oxygen to water is also 43 grams to x
Cross multiply: 13x = 430 grams
Isolate x: x = 33.0769g
Remember that n = mass/Molar mass
The molar mass of water is 18.01528 g/mol
n = 33.0769/18.01528
n = 1.836048
