Answer:
The answer to your question is the second one
Explanation:
AC + B → AB + C
This is not the right answer, the reaction shown here is a single replacement reaction in which one element replaces another element that is part of a compound.
A + B + C → ABC
This is the right answer because in synthesis reactions two or more reactants bound to form only one product.
ABC → A + B + C
This answer is incorrect because this is an example of a decomposition reaction in which one reactant forms two or more products.
AB + CD → AC + BD
This is an example of double replacement reaction in which the cations and anions of the reactants are interchanged.
Balanced equation: 10 CaCo3 + 20 HCl = 10 CaCl2 + H20 + 15 Co2
Connective tissue is one of the four different types of tissues. It consists of cells suspended in a matrix, and consist of fibres running through it. It’s main job is to connect internal tissues. They also support and protect internal organs. Examples include cartilage, blood, lymph and adipose tissue.
Answer:
Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
