Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.84 × 10^24 C. 4.61 × 10^23 D. 7.87 × 10^23
Answers
Answer:
B
Explanation:
first find the no. Of moles of H2SO4
= 75/98.1
= 0.7645
Next step
In on mole of H2SO4 the no.of oxygen atom is 4.
1 H2SO4 : 4 O
0.7645 : x x= 0.7645x4= 3.0581
next multiply avogadros constant
3.0581 x 6.022× 10^23 =1.84x10^24
Mass present in 1 gram of mole substance is called molar mass. Molar mass is calculated by: dividing the mass of the compound in grams by the number of moles present in the substances.
The correct answer is:
option B. 1.84 × 10²⁴
Given,
The mass of sulfuric acid =75.0 gThe molar mass of sulfuric acid = 98.1 g/mol
1.The moles of sulfuric acid can be calculated by
M = m ÷ n
where M is molar mass, m is mass and n moles.
moles of sulfuric acid = mass ÷ molar mass
= 75 g ÷ 98.1 g/mol
=0.7645 moles
Hence moles of sulfuric acid present is 0.7645 moles.
2. 1 mole of sulfuric acid = 4 oxygen atoms.
Then, 0.7645 moles of sulfuric will contain: 0.7645 × 4 = 3.0581 atoms of oxygen
3. Oxygen atoms present in 75.0 g of H₂SO₄ will be calculated by multiplying it with Avogadro's constant:
= 3.0581 x 6.022× 10²³
= 1.84x10²⁴
Therefore, 1.84 × 10²⁴ oxygen atoms will be found in 75.0 g of H₂SO₄.

An example of a double replacement chemical reaction takes place in batteries. In an alkaline battery, Manganese oxide reacts with water to form a different manganese oxide and hydroxide. Which is the correct balanced equation for this?
Answers
Answer:
2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation.
When manganese oxide reacts with water to form a different manganese oxide and hydroxide, the correct balanced equation for this is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.
What do you mean by balanced chemical equation ?The term balance chemical equation is define as the equation which satisfy the law of conservation of mass, i.e., “Total mass of the products is equal to the total mass of all the reactants”.
If a chemical equation is not balanced, it will break the law of conservation of mass. It will indicate that either mass is created or destroyed, which is impossible.
Balanced chemical equations have the equal number and type of each atom on both sides of the equation.
Thus, When manganese oxide reacts with water to produce a different manganese oxide and hydroxide, the correct balanced equation for this reaction is 2MnO₂ + H₂O ⇾ Mn₂O₃ + 2OH.

A. He is incorrect, because water can dissolve ionic solids.
B. The test proves nothing, because water dissolves all solids.
C. He is correct, because polar liquids cannot dissolve ionic solids.
D. The test proves nothing, because it only shows that the solid is a compound.
(I know water is polar, so I think its a?)
Answers
The student cannot prove that if the compound is ionic or covalent because not all ionic compounds dissolves in water. Some ionic compounds have higher lattice energy results in lower solubility. Thus, option D could be correct.
What are ionic compounds?Ionic compounds are formed between metals and non metals. Metals are electron rich and they easily donate electrons to the non-metals. Non-metals are generally electronegative and they easily gains electrons from the metals.
Donating electrons make metals acquire positive charge and the non-metals acquire a negative charge. This charge separation make the compound possess a permanent dipole moment. Which make them easily soluble in water by ion-dipole interaction.
However, some ionic compounds have very strong ionic bonds and their binding energy will be greater so that cannot be easily dissolved in water. For example, AgCl. Therefore, we cannot predict weather the compound is ionic or not by simply noting it solubility in water.

Cuando se queman combustibles que tienen algún compuesto de azufre se produce dióxido de azufre (SO2), un gas irritante que puede provocar lluvia ácida. En el análisis del aire de una ciudad se ha encontrado una concentración de SO2 de 14 mg/m^3 ¿Qué cantidad de SO2 habrá en 1 L de aire?
Answers
Answer:
See answer below
Explanation:
I have to answer this question in english because is the rule here. I hope you can understand this.
Now, in order to answer this, is really easy. We already have the quantity of SO₂ in the air of a city. This concentration is 14 mg/m³, so we want to know the quantity in 1 L. This quantity can be expressed in mass.
If concentration according to the units is: mg/m³ This means that we have units of mass and volume. So, in order to know the quantity of SO₂ in mass, we need to convert the units of volume m³ to liter.
1 m³ is covered in 1000 L, therefore:
14 mg/m³ * 1 m³/1000 L = 0.014 mg/L
Then, the mass will be:
m = 0.014 mg/L * 1 L
m = 0.014 mg of SO₂
This is the quantity of SO₂ in 1 L.

A chemistry student mixes 25 milliliters of 3.0 M hydrochloric acid (HCl) with excess sodium hydroxide. The chemicals react according to this chemical equation:
HCl + NaOH → NaCl + H2O.
If the volume of the resulting solution is 68 milliliters, what is the concentration of sodium chloride?
Answers
Answer:
1.1 mol/liter
Explanation:
You would use the M1V1 = M2V2 equation to solve this.
We know M1 is 3.0 M, V1 is 25 milliliters, and V2 is 68 milliliters. We need to find M2.
To find M2, first plug in what you know.
(3.0 M)(25 mL) = M2(68 mL)
Then, divide everything by 68 mL to get M2 by itself
Your answer should be a quite large decimal but I rounded it to 1.1 mol/liter.
Answer:
The concentration of sodium chloride is 1.1 moles/liter.
