Covalent bonding is referred to as “sharing” electrons. Is it really sharing? Why or why not?

Answers

Answer 1

Answer:

yes

Explanation:

because they will bond in order to gain more stability which is gained by forming a full electron shell

beause of gravitys pull and because the atmosphere of the beyond lol also bcs this i hope this helps your welcome boo >3

Explanation:

Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Contains elements carbon, hydrogen and oxygen, the empirical formula of butanedion is C2H3O and its molar mass is 86.09% find its empirical formula

Answers

Answer:

Molecular formula = C₄H₆O₂

Explanation:

Given data:

Empirical formula of butanedion = C₂H₃O

Molar mass of  butanedion = 86.09 g/mol

Molecular formula  butanedion = ?

Solution:

Formula:

Molecular formula = n(empirical formula)

n = molar mass of compound / empirical formula mass

empirical formula mass  = 2×12 +1.008×3 +1×16 = 43.024

n = 86.09 / 43.024

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₃O)

Molecular formula = C₄H₆O₂

What would pressure be if volume was 0

Answers

Answer:

The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.

Explanation:

Answers

Answer:

3. One example of condensation is dew forming on grass or leaves early in the morning when the air is cooled/cooling.

4. This is called freezing. For example, when water turns into ice (a solid) because it freezes.

5. This is called melting. The butter reached its melting point and turned into a liquid.

6. Adding or removing energy causes changes in states of matter. Temperature for example can cause melting and freezing.

7. Water which collects as droplets on a cold surface when humid air is in contact with it.

8. Evaporation/vaporization

9. before- particles are compact

during- particles vibrate

after- the particles move freely

10. condensation because it is going from gas into a liquid

11. Evaporation, I know because when liquid gets heated after a period of time  and it reaches its boiling point, it will begin evaporating.

12. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

13. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.

14. freezing because particles are becoming compact and getting slower because of decrease in temperature

15. Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.

16. Try and think of it in terms of the molecules. The temperature is such that the molecules are all bound together into a solid. Occasionally a surface molecule picks up enough energy to break it bond,.. a statistical probability ,and drifts away. The overall temperature of the solid is reduced by that event,as temperature is just an average of the energy. A little more heat flows into the material ,from the ambient environment, and another molecule escapes, and so the process continues….. if the concentration of the molecules in the vapour space above the solid, is low the reverse process of molecules condensing onto the surface,and releasing energy back into the solid is low.

Why does ketchup flow faster when heated?

Answers

Answer: Explanation:

With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. ... With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.

liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

A substance has an atomic number of 80 and a mass number of 178. How many protons does this atom have? How many neutrons does it have? How did you determine this? Write your answer in ACES format.

Answer:

Cite (source and evidence):

Explain:

Summarize:

Answers

Answer:

This atom has 80 protons and 98 neutrons.

Explanation:

All atoms are composed of a central nucleus in which there are positively charged particles, the protons, and neutrally charged particles, the neutrons, around which other negatively charged particles, called electrons, move.

The atomic number, identified with the letter Z, indicates the number of protons that are present in the nucleus of an atom. The atomic number defines the electronic configuration of the atom and allows the ordering of the different chemical elements in the periodic table.

If a substance has an atomic number of 80, this atom has 80 protons.

The mass number indicates the total number of particles in the nucleus, that is, the sum of protons and neutrons.

mass number = number of protons + number of neutrons

In this case you know that the mass number is 178 and number of protons is 80. Then

number of neutrons=mass number - number of protons

number of neutrons= 98

So this atom has 98 neutrons.
