How many moles of acetaminophen are in a 0.8mL (0.0008L) dose of infants Tylenol

Answers

Answer:

0.007 mol

Explanation:

Step 1: Given data

Volume of acetaminophen: 0.8 mL

Step 2: Calculate the mass corresponding to 0.8 mL of acetaminophen

The density of acetaminophen is 1.26 g/mL.

0.8 mL × (1.26 g/mL) = 1 g

Step 3: Calculate the number of moles corresponding to 1 g of acetaminophen

The molar mass of acetaminophen is 151.16 g/mol.

1 g × (1 mol/151.16 g) = 0.007 mol

You have a 155-g sample of Al2O3. If there are 22.5 g of Al in the solution, what is the percent by mass of the solute? Use details to support your answer.

Answers

Answer:

14.52%

Explanation:

The percentage by mass (WW%) is calculated by using the formula:

Mass of solute/mass of solution ×

100

The solute (Al) is 22.5g while the solvent (Al2O3) is 155g

Hence, percent by mass is:

22.5/155 × 100

= 0.1452 × 100

= 14.52%

How many moles of oxygen are needed to burn 2.7 moles of methyl
alcohol (CH3OH)?
2CH2OH + 302 -→ 2CO2 + 4H2O
please show how you got it

Answers

Answer:

3.38 moles of O2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

4CH2OH + 5O2 → 4CO2 + 6H2O

From the balanced equation above,

4 moles of CH2OH required 5 moles of O2 for complete combustion.

Finally, we shall determine the number of mole of O2 needed to react with 2.7 moles of CH2OH. This can be obtained as follow:

From the balanced equation above,

4 moles of CH2OH required 5 moles of O2 for complete combustion.

Therefore, 2.7 moles of CH2OH will require = (2.7 × 5)/4 = 3.38 moles of O2 for complete combustion.

Thus, 3.38 moles of O2 is required.

D- It is no different than the rock layer below

Answers

Hello there!

Your answer is C.

Answer:

The right option is; A. It is younger than the rock layer below.

Explanation:

A rock layer deposited on top of another rock layer is younger than the rock layer below. This is based on the law of superposition which states that in any undeformed sequence of rocks that are laid down in layers, the youngest layer of rock will be on top of the sequence, while the oldest layer will be at the bottom of the sequence.

electrons to form an ion.
What will be the charge on the ion?
What will be the number of protons and electrons in the ion?

Answers

Answer:

+3

12 electrons and 15 protons.

Explanation:

The element having 15 electrons and 15 protons have atomic number 15. We know that when an atom lose or gain the electron ions are formed.

Anion formation:

Anion is formed when electron is accept by an atom.

X + e⁻ → X⁻

Cation formation:

Cation is formed when electron lose be an atom.

X → X⁺ + e⁻

The given atom loses 3 electrons thus oxidation number will be +3 and cation is formed.

X → X³⁺ + 3e⁻

Now element X have 15 protons and 12 electrons.

What coefficient well O2 have after balancing this equation

C4H8 + O2 -> CO2 + H2O

A. 4

B. 8

C. 6

D. 2.5

Answers

coefficient of O2 will be 6

The coefficient for O₂ after balancing the equation is 4. The correct answer is A. 4.

To balance the equation C₄H₈ + O₂ → 4CO₂ + 4H₂O, we need to ensure that the number of each type of atom is the same on both sides of the equation.

Starting with carbon (C), we have 4 carbon atoms on the left side and only 1 on the right side (in CO₂). To balance carbon, we place a coefficient of 4 in front of CO₂:

C₄H₈ + O₂ → 4CO₂ + H₂O

Next, we move on to hydrogen (H). There are 8 hydrogen atoms on the left side, but only 2 on the right side (in H₂O). To balance hydrogen, we place a coefficient of 4 in front of H₂O:

C₄H₈ + O₂ → 4CO₂ + 4H₂O

Now, let's consider oxygen (O). On the left side, we have O₂, which contains 2 oxygen atoms. On the right side, there are 4 CO₂ molecules, each containing 2 oxygen atoms, and 4 H₂O molecules, each containing 1 oxygen atom. So, the total number of oxygen atoms on the right side is (4 x 2) + (4 x 1) = 8.

To balance oxygen, we need to have 8 oxygen atoms on the left side as well. Therefore, we place a coefficient of 4 in front of O₂:

C₄H₈ + 4O₂ → 4CO₂ + 4H₂O

Therefore, the coefficient for O₂ after balancing the equation is 4.

The correct answer is A. 4.

Depicted below you will see the molecules COH2 and SO3 . Why is COH2 polar while SO3 isn’t?

Answers

Answer:

See explanation

Explanation:

When we look at SO3 we will notice that the compound is trigonal planar and it is symmetric. This means that it has equal charge distribution hence its dipoles cancel out resulting in a zero net dipole moment.

However, COH2 is also trigonal planar but is non-symmetric. Hence, its dipole moments do not cancel out, hence the molecule has a resultant dipole moment and is a polar molecule

The half-life of carbon-14 is 5,730 years. Dating organic material by looking for C-14 can't be accurately done after 50,000 years. Suppose a fossilized tree branch originally contained 4.30 grams of C-14. How much C-14 would be left after 50,000 years?

Answers

Answer:

0.010g of C-14 would be later after 50,000 years

Explanation:

The kinetics of radioactive decay follows the equation:

Ln (N / N₀) = -kt

Where N could be taken as mass after time t,

N₀ initial mass = 4.30g;

k is rate constant = ln 2 / t(1/2)

= ln 2 / 5730years = 1.2097x10⁻⁴ years ⁻¹

Replacing:

Ln (N / 4.30g) = -1.2097x10⁻⁴ years ⁻¹ * 50000 years

N / 4.30 = 2.36x10⁻³

N =
