Carbon has 4 valence electrons and has a close electronegativity like that of hydrogen and other nonmetals. Because of this, it tends to form covalents bonds equally spaced around it. The best association to this is the lewis structure for methane,CH4.
Carbon has the ability to for covalent bonds with other elements beside from itself. These bonds are the: single covalent bond; the double covalent bond; and, triple covalent bond.
There are two types of mixture depending on the distribution of the components in the mixture. Homogeneous mixtures are mixtures which has uniform properties all throughout the solution while heterogeneous mixtures are the opposite they do not exhibit uniformity in any property. Example for a homogeneous is a salt solution where at any point you get a sample the properties are the same. For the heterogeneous mixture, a mixture of sand and salt where at any sampling point the properties are not the same.
a suspension
the particles are big enough to settle
a colloid
the particles are too small to ever settle
a solution
homogeneous mixture of two or more substances
a. Cl, Br, Ga
Answer:
Br,Ga,Cl?
Explanation:
The answer is has a Moh's hardness of 1.
Answer:
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
Hope this helps you
