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.
Answer:
the last one
Explanation:
A is the solution and the solvent and B is the solute
Answer: B
Explanation:
The more dense an object is, the more it will sink below something. If the liquid below the more dense object is even denser, it is going to sink.
The light object will not be able to handle the heavy object. The answer to the question is option B.
Answer:
Number of moles = 0.35 mol
Explanation:
Given data:
Mass of H₂SO₄ = 34.6 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of H₂SO₄ = 98.1 g/mol
by putting values,
Number of moles = 34.6 g/ 98.1 g/mol
Number of moles = 0.35 mol
Answer:
Included in the Lewis definition of acids are the metal ions; the oxides of certain nonmetallic elements, such as sulfur, phosphorus, and nitrogen; substances able to donate hydrogen ions or protons; and certain solid compounds, such as aluminum chloride, boron trifluoride, silica, and alumina. ;)
