Balanced chemical reaction:
CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O(l).
Calcium carbonate (CaCO₃) dissolves in hydrochloric acid and gas carbon(IV) oxide is formed.
Calcium carbonate is inorganic salt insoluble in water, but soluble in acidic solutions.
Answer:
Convergent boundaries form when two crustal plates are colliding. ... The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma ... If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.
Explanation:
Answer: Sublimation
Explanation: The process of a solid becoming a gas is called sublimation.
An element can be represented symbolically in terms of its atomic number and mass number as:
\[_{Z}^{A}\textrm{X}\]
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
\[_{0}^{1}\textrm{n}\]
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
Answer:
separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.
