is there supposed be a picture with the question?
The solution which would react vigorously with zinc carbonate is Hydrochloric acid.
Explanation: When Zinc carbonate (ZnCO3) reacts with Hydrochloric acid (HCl), it gives rise to zinc chloride (ZnCl2) and carbon dioxide (CO2).
Answer:
As 1 mole =6.023×10^23 atoms
So, No of moles in 2.75×10^24 atoms = 4.56 moles
So,~4.56 moles are there in 2.75 ×10^24 atoms of carbon
The answer is B. Lithosphere
Explanation: The upper layer of mantle is a zone of rigid brittle rock. Below the lithosphere is asphalt-like and is called the Asthenosphere.
Answer:
Plasma.
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
I. Solid.
II. Liquid.
III. Gas
Plasma can be defined as a state of matter in which the electrons temporarily separate from the protons and as a result, it is generally referred to as the fourth (4th) state of matter due to its superheated nature.
