Answer : Acid-base reaction is determined when hydrogen ion of an acid neutralize by the hydroxide ion of a base then it gives water.
Explanation :
Acid-base reaction : It is defined as the reaction in which an acid reacts with a base to give salt and water.
Acid-base reaction is determined when hydrogen ion of an acid neutralize by the hydroxide ion of a base then it gives water.
For example: When hydrochloric acid react with sodium hydroxide base to give sodium chloride salt and water.
The balanced acid-base reaction is:
B. atom
C. neutron
D. electron
Answer:
D. electron
Explanation:
Electrons have a negative charge
The number of oxygen atoms in 19.3 g of sodium sulfate (Na₂SO₄) is 3.27×10²³ atoms
We'll begin by calculating the number of mole in 19.3 g of sodium sulfate (Na₂SO₄).
Mass of Na₂SO₄ = 19.3 g
Molar mass of Na₂SO₄ = (23×2) + 32 +(16×4)
= 46 + 32 + 64
= 142 g/mol
Mole = mass / molar mass
Mole of Na₂SO₄ = 19.3 / 142
1 mole of Na₂SO₄ contains 4 moles of O.
Therefore,
0.136 mole of Na₂SO₄ will contain = 0.136 × 4 = 0.544 mole of O
Finally, we shall determine the number of atoms in 0.544 mole of O.
From Avogadro's hypothesis,
1 mole of O = 6.02×10²³ atoms
Therefore,
0.544 mole of O = 0.544 × 6.02×10²³
0.544 mole of O = 3.27×10²³ atoms
Thus, 19.3 g of sodium sulfate (Na₂SO₄) contains 3.27×10²³ atoms of oxygen.

Answer:
3.27·10²³ atoms of O
Explanation:
To figure out the amount of oxygen atoms in this sample, we must first evaluate the sample.
The chemical formula for sodium sulfate is Na₂SO₄, and its molar mass is approximately 142.05.
We will use stoichiometry to convert from our mass of Na₂SO₄ to moles of Na₂SO₄, and then from moles of Na₂SO₄ to moles of O using the mole ratio; then finally, we will convert from moles of O to atoms of O using Avogadro's constant.
19.3g Na₂SO₄ · · ·
After doing the math for this dimensional analysis, you should get a quantity of approximately 3.27·10²³ atoms of O.
Answer:
Water.
Explanation:
Hello,
In this case, you are referring to the dissociation or formation of water at the equilibrium, that is:
In such a way, the water is the conjugate acid of the hydroxile ion as long as it gains a proton.
Best regards.

SO₃+ H₂SO₄ → H₂SO₄ This reaction is synthesis type of reaction, because that would be combination (synthesis) A + B → AB. Therefore, option A is correct.
There are five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
Biochemical reactions are chemical reactions that occur within living things. Metabolism refers to the sum of all biochemical reactions in an organism. Exothermic and endothermic chemical reactions are both part of metabolism.
Hydration is the process of combining water molecules with another substance to form a single, new compound. SO3 is an acidic oxide that reacts with and dissolves in water to form sulfuric acid, H2SO4.
Thus, option A is correct.

Answer:
A polysaccharide (n) can be formed by linking several monosaccharides through glycosidic linkages.
Explanation:
Polysaccharides are carbohydrates or complex carbohydrates, where monosaccharides join with glucosidic bonds to form a more complex structure that would be the polysaccharide.
An example of a polysaccharide is starch, or glycogen.
Starch is found in many foods such as potatoes or rice, and glycogen is a form of energy reserve of our organism housed in muscles and liver to fulfill locomotion, physical activity, and other activities that consist of glycolysis.
Polysaccharides are degraded in our body by different stages, and several enzymes unlike monosoccharides or disaccharides, since they have more unions and a more complex structure to disarm in our body and thus assimilate it.
Polysaccharides are also part of animal structures, such as insect shells or nutritional sources, among others.
