Answer:
It would take you 8 hours.
Explanation:
This would take you 8 hours because you are going 1 mile an hour. So in 1 hour, you would have gone 1 mile.

Explanation:

The correct answer is option A: CH3COCH3
Hydrogen bonding occurs when hydrogen is directly bonded to a highly electronegative atom.
Hydrogen bonding is one of the intermolecular interactions. It occurs only when hydrogen is bonded to a very electronegative atom in a molecule. Hydrogen bonding can occur between two molecules of the same type(intermolecular hydrogen bonding) or within the same molecule (intra molecular hydrogen bonding). In either case, the bonding is polar as hydrogen is attached to the electronegative atom via a non-covalent bonding interaction.
Looking at the structures in the question attached, CH3COCH3 does not have any hydrogen atom directly attached to a highly electronegative atom hence CH3COCH3 does not exhibit hydrogen bonding.
Hydrogen bonding in water is shown in the image attached.

After a lightning storm, the Rodriguez family notices the TV no longer works.
What probably caused this malfunction?
A. Power from the TV was pulled into the ground by the lightning.
B. A power surge burned an electric component of the TV.
C. The lightning sucked power from the TV.
D. The surge protector sucked power from the TV.
Answer:
B
Explanation:
A P E X
After a lightning storm, the Rodriguez family notices the TV is no longer working because a power surge burned an electric component of the TV. The correct option is B.
What is lightning?Lightning is a natural phenomenon that occurs when there is a collision of negative and positive charged particles. It appears as light or spark of electricity into the earth. It shines and affects the eyes if directly seen.
Lightning occurs when there is thunder or rain, lightning causes destruction to the earth, the houses, trees, and people are also impacted by this. The TV was not working because there was a short circuit due to lightning.
Thus, the correct option is B. A power surge burned an electric component of the TV during a lightning storm.

How many electrons can be present in an atom having three principal
energy levels? *
Answer:
18 electrons
Explanation:
The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons. The fourth and higher levels have an f sublevel in addition to the s, p, and d orbitals.
Answer:
18 electrons
Explanation:
The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.
What is the molarity of a sodium carbonate solution containing 32.52 g Na2CO3 dissolved in enough water to make 822 ml of solution?
NEED ASAP PLEASE!!
The molarity of a Sodium carbonate solution : 0.373 M
Further explanationGiven
32.52 g Na₂CO₃
822 ml of solution = 0.822 L
Required
The molarity
Solution
Molarity shows the number of moles of solute in every 1 liter of solution.
[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]
mol of solute = mol of Na₂CO₃ :
= mass : MW Na₂CO₃
= 32.52 g : 106 g/mol
= 0.307
Molarity :
= n : V
= 0.307 mol : 0.822 L
= 0.373 M
9) A certain atom has 10 electrons, 14 neutrons, and 11 protons. Write the name of this element in isotope notation.
Answer:
²⁵₁₁Na⁺
Explanation:
Details about the atom:
Number of electrons = 10 electrons
Number of neutrons = 14 neutrons
Number of protons = 11 protons
The atomic number of an atom is a good indicator of the type of atom we have been given.
From the subatomic particles, the number of protons is the same as the atomic number.
Since the number of protons is 11, its atomic number will be 11.
The element with atomic number 11 is sodium, Na.
To write a complete notation, we also need the mass number;
Mass number = number of protons + number of neutrons
Mass number = 11 + 14 = 25
The charge on the atom:
Charge = Number of protons - number of electrons = 11 - 10 = 1+
The element in isotopic notation is given as;
²⁵₁₁Na⁺
We have seasons because
Answer:
Earth's axis is tilted at an angle of about 23.4 degrees and different parts of Earth receive more solar energy than others. Earth's orbit around the Sun is elliptical. Because of Earth's axial tilt (obliquity), our planet orbits the Sun on a slant which means different areas of Earth point toward or away from the Sun at different times of the year.
