Answer:
1.5g
Explanation:
According to this question, the amount of copper required to obtain copper sulfide in a 4:1 is 6g. This means that the ratio of copper to sulfur in the compound (copper sulfide) is 4:1.
Hence, to calculate the amount of sulfur required for the reaction to obtain copper sulfide using the above ratio, we say:
1/4 of the amount of copper required (6g)
= 1/4 × 6
= 6/4
= 1.5g of sulfur is required for the reaction to obtain carbon sulfide.
An atom of fluorine would possess 7 valence electrons as it is found in group 7 of the periodic table.
The group number in this case corresponds to the number of valence electrons present.
So, for instance, because Chlorine is also found in group 7, it would also have 7 valence electrons.
Kinetic enery is the energy that exists as movement of the particles of a substance. This energy would be greater in faster-moving particles as compared to slower-moving particles. Potential energy, on the other hand, is the energy that can be stored in the position of an object and in the position of the particles that make up a substance. Kinetic energy and potential energy are affected by the mass of an object. It is directly related so that the greater the mass the greater the energy would be present in the object and the smaller the mass, the smaller the amount of the energy present.
The answer is NH4Cl!
Ionic bonding=cation + anion
- the cation ammonium (NH4) has a single electron in its valence shell, and Chlorine needs a single electron to fill its valence shell, and they stick together.
Covalent bond= involves the sharing of electron pairs between atoms
- present in Ammonium ion between Nitrogen and Hydrogen atoms
