Answer:- D) particles .
Solution:- There are 1.53 moles of the compound are given and it asks to calculate the number of particles.
To calculate the number of particles we multiply the moles with Avogadro number.
=
So, the D is the right choice.
Answer:
law of conservation of mass
Explanation:
According to the law of conservation of mass, mass is neither created nor destroyed.
This is actually the law that guides the balancing of chemical reaction equations.
On the left side we have four atoms of hydrogen and two atoms of oxygen. Exactly the same number of atoms of each element is seen on the right hand side in accordance with the law of conservation of mass.
Answer:
- Elements of the the same group have similar number of valence electrons.
- They have identical number of electrons in their outermost shell. For example ; All the alkali metals in Group 1 have 1 valence electron.
And so many more.
Due to all these similarities ,they have similar properties and they tend to react similarly with other substances.

Answer:
.
Explanation:
In graphite, the carbon atoms are joined together and arranged in layers. The links between the carbon atoms in the layer are strong, but the links between the layers are weak. The layers easily slip over each other. ... Graphite is a non-metal and it is the only non-metal that can conduct electricity.
Metals nonmetals and Metalloids is the answer
