Answer: c
. Alkaline earth metals (Group 2)</h2>
<h3>
Explanation:</h3>
Group 2 metals have 2 electrons in their outer shell. These two electrons are usually found in the s orbital, hence the s².
The answer will be D because the reaction is what's first(A) and then it is the product that comes out.
Hello!
Before I can answer your question we need to know the different types of chemical reactions that can occur:
- Single Replacement
- Double Replacement
- Synthesis
- Decomposition
- Combustion
Combustion is an answer that can usually be ruled out unless oxidation is occuring in the chemical equation (hyrdrogen occuring with oxygen to react)
Synthesis reaction, also known as a Combination reaction, is when the reactants combine to form a single product.
Decompostion is when a single reactant is deconstructed to form multiple products, or the opposite of Synthesis.
With these definitions alone, since they are opposite types of reactions, the answer would be Synthesis and Decomposition reactions !
Hope this helps and if you need anymore clarification feel free to ask.
Answer:
Grade A is the best percentage that is developing, proficient, exceeding, and emerging
The top number of a portion is called its numerator whereas the bottom number is its denominator. So a Fraction is the quantity of shaded parts separated by the quantity of a balance of as demonstrated as follows: number of shaded parts is the numerator over the whole part which is the denominator.
