Answer:

after gathering initial data and defining the research​

Explanation:

"Hypothesis" refers to the researcher's scientific guess or prediction about the outcome of a research. Such expectation is being done after gathering initial data and defining the research, which means it happens before even conducting the study.

Under hypothesis, the variables' relationships are being predicted but with no evidence yet. It is very important to make a hypothesis according to three criteria: specificity and clearness, testability and falsifiability.

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

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 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.

Answer:

The CNO cycle (for carbon–nitrogen–oxygen) is one of the two known sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain reaction (pp-chain reaction). Unlike the latter, the CNO cycle is a catalytic cycle.

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.

Answer:

Sodium is an alkali metal so it needs to lose an electron to fill it's outer shell.

That is an ion. When an element loses or gains an electron but in this case, sodium needs to lose an electron.

Answer:

700 mL of ethanol would be added

Explanation:

Given data:

Volume of ethanol added to make 40% v/v solution = ?

Total volume of solution = 1750 mL

Solution:

We will calculate the 40% 1750 mL which will be the volume of ethanol added to the water to make 40%v/v solution.

(40/100)× 1750 mL

0.4 × 1750 mL

700 mL

700 mL of ethanol would be added.

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%

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.
