No, an element is a pure substance, it cannot be broken down into simpler substances or be decomposed by chemical means.
Answer:
The answer is chemical weathering due to water reacting with calcite
Explanation:
The causes of chemical weathering include the action of water, oxyen, carbon dioxide, living organisms, and acid rain.
Answer: is in excess.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require 2 moles of
Thus 0.29 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
Answer:
N, Ne, F, B, Li
Explanation:
Valence electrons are the electrons that are found in the outermost shell in a neutral atom. These five elements are the only one whose valence electrons fall on the same shell. The second shell. Their electronic configurations are as follows:
N: 2,5
Ne:2,8
F:2,7
B:2,5
Li: 2,3
