Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
Answer:
B.) classification
Explanation:
In biology, classification is a way to organize living things. In science generally, this could expand to include any type of object.
Answer:
C. A steep slope
Explanation:
Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.
Agents of erosion are wind, water, glacier and gravity.
Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.
On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.
Answer:
a. Approximately half of those with anorexia nervosa go on to develop bulimia nervosa, indicating that the two disorders may not be distinct but may represent phases of the same eating disorder.
Answer:
Calcification, or mineralization, then occurs when hydroxyapatite crystals deposit in the bone matrix.
Explanation:
Calcification -
It is the situation of the accumulation of the salts of calcium in the tissues of the body , is known as Calcification .
This process usually occurs during the bone formation , but in abnormal condition the soft tissues of the body gets harden , leading to the situation of Calcification , it is also known as mineralization .
The crystal deposited are of hydroxyapatite in the bone matrix .
