Answer:
Hi! In this case, the reactioncan be correctly balance according to this: 2Al(s) + 3CuSO4(aq) –> Al2(SO4)3(aq) + 3Cu(s).
Explanation:
In this particulary reaction,two semi-reactions happens.
One involving the metallic aluminum that suffers an oxidation reaction:
Al (s) -> Al3 + (aq) + 3e–
and another is a reduction reaction involving copper;
2e– + Cu2 + (aq) -> Cu (s)
Answer: Option (B) is the correct answer.
Explanation:
A covalent compound is a compound formed by sharing of electrons. And, in a covalent network solid atoms are bonded by covalent bonds in a continuous network that is extending throughout the material or solid.
This continuous arrangement of atoms are like a lattice.
For example, diamond is a covalent network solid in which carbon atoms are arranged in a continuous lattice like structure.
Hence, we can conclude that the statement all the atoms are covalently bonded to other atoms to form a lattice-like structure, best describes the structure of covalent network solids.
Answer:
<h3>The answer is 1000 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of object = 50 mL
density = 20 g/mL
We have
mass = 20 × 50
We have the final answer as
<h3>1000 g</h3>
Hope this helps you
