Answer:
Evaporate minerals are more soluble than calcite and quartz.
Explanation:
Evaporate minerals are the water soluble minerals which at higher concentration precipitate out and crystallized forming rocks.
example of chemicals present are:
chlorides and sulphates.
Quartz is silica (very less soluble, or insoluble)
Calcite is calcium carbonate, again an insoluble salt.
Thus
Evaporate minerals are more soluble than calcite and quartz.
Same number of valence electrons
Explanation:
Two elements posses similar chemical properties if they have the same number of valence electrons.
Chemical properties of any substance is determined by the number of valence electrons it possesses in its outer most shell.
Elements use their valence electrons to form chemical bonds with one another.
Elements with the same number of valence electrons will chemically combine the same way.
This is why elements in the same group on the periodic table have the same chemical properties.

Answer:
it depends on the mass of the object but sometimes smaller objects have more density the higher the mass the the lower the density
Answer:
See the answer below
Explanation:
Although there are no specific options available to choose from, some of the general safety measures or precautions that must be observed when using a bunsen burner are as follows:
- <em>Always leave, at least, 12 inches of space between the bunsen burner and the nearest object. This is to avoid the nearby object catching fire accidentally.</em>
- <em>Always watch the flame at all times, never leave it unattended to.</em>
- <em>Burners should not be handled unless ample time has been given for them to cool down. This is to avoid burning-related injuries.</em>
- <em>Burner fittings should be carefully checked to ensure there are no leakages. Gas leakages may cause serious accidents.</em>
- <em>Always use a sparker as this is safer than using matches or lighter.</em>
- <em>The gas supply must always be turned off whenever the burner is not in use.</em>
