Answer:
The analysis is: acetic acid will be too low because of the acid that may still be in the water.
Explanation:
We know that the amount of acetic acid in vinegar is determined by the volumetric titration of acetic acid with standardized NaOH solution; because it doesn't affect the number balance of hydronium and hydroxide ions.
This percent by mass of acetic acid will be too low because of the acid that may still be in the water.
Now if the deionized water is contaminated in this case with carbonic acid, so there would be a consumption of a higher amount of NaOH for neutralization as a result. Therefore, the amount will depend on many factors.
Answer:
It allowed families to have a keepsake representation of their fathers or sons as they were away from home.

Answer:
The correct answer is B. They are a collection of minerals or a body of glass.
Explanation:
The study of rocks needs the observation of their characteristics; its characteristics depend on the properties of the minerals that compose it, its relative amounts and the way in which these were joined to originate the rock. Texture is the external appearance of any rock. It depends on the shape, size and internal arrangement of mineral crystals. Each of these characteristics maintains its specific properties (chemical and physical) in the rock as a whole.
In a rock we can distinguish two types of minerals:
Essential minerals. They are the ones that constitute the nature of the rock and give it its characteristics and properties for being in greater proportion. The lack of one of them would result in the formation of a different rock with different properties.
Accessory minerals These are minerals that appear occasionally in very low proportions within the typical composition of a particular rock. Its presence does not alter the basic characteristics of the rock.
