Explanation:
im sorry but it depends on what the diagram looks like for the problem
Answer:
B:GRANITE
Explanation:
<em>Granite is typical of a larger family of granitic rocks that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals.</em>

These properties have made granite a widespread construction stone throughout human history.</em>

Explanation:
The generated Na+ and OH-ions are immediately surrounded by molecules of water (typically 6, each). There is the development of the exothermic hydration sphere for each ion. It seems as though there is negative overall energy of dissolving solid NaOH.
Now, since this dissolution is exothermic the temperature of the mixture rises.
Answer:
The value is 
Explanation:
From the question we are told that
The molar mass of 
is 
The total mass is 
The uncertainty of the total mass is 
Generally the molar weight of calcium is 
The percentage of calcium in calcite is mathematically represented as
Generally the mass of each sample is mathematically represented as
Generally mass of calcium present in a single sample is mathematically represented as
The uncertainty of mass of a single sample is mathematically represented as
The uncertainty of mass of calcium in a single sample is mathematically represent
Generally the average mass of calcium in each sample is
<span>When two or more substances are mixed together but not chemically joined they are called as mixtures. Therefore, it is only a physical change taking place.
