before making a covalent bond, where do the atom's electrons spend most of their time?

Answer: A, Carbon Dioxide

Explanation:

A. Soda water, like other carbonated beverages, contains carbon dioxide that has dissolved under pressure. When the pressure is released by opening the soda container, the liquid cannot hold as much carbon dioxide, so the excess bubbles out of the solution.

Answer:

A. carbon dioxide

Answer:

Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.

Explanation:

Answer:because the chemical formula is vital to the equation it tells you what creates the chemical and whats in it you can change the exponents but not the formula itself

Answer:

In fact, the moon is one of the least reflective objects in the solar system. The DSCOVER spacecraft captured this single photograph of the moon and the earth. Both the earth and the moon are illuminated by the same amount of sunlight coming from the same angle in this photo.

The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.

Explanation:

Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

The measurement of a star depends on the distance of the star from earth

is Apparent magnitude.

The apparent magnitude of a star is how bright the star appears in the sky

from the earth. The apparent magnitude of a star depends on two main

Answer: 2.85 moles of flourine

Explanation:

find the atomic/molar mass of flourine on your periodic table.

multiply the given mass (54.1g) by (1 mole of flourine/atomic mass of flourine)

54.1g flourine * 1mole of flourine/18.998g flourine

(g flourine) in the above equation cancel each other.

54.1/18.998 = 2.85 mole of flourine

Gas has the most spread out particles.

Explanation:

Heavier particles will move more slowly and so will have a slower rate of diffusion. Smaller particles on the other hand will diffuse faster because they can move faster.

Explanation:

Answer:

Because all machines lose input work to friction, one way to improve the efficiency of a machine is by reducing friction. Oil is used to reduce friction between the moving parts of car engines. The use of oil makes engines more efficient. Another machine that loses input work is a bicycle.

Explanation:

Hope this helps.

The factor which increases as the efficiency of a machine increases is: work output.

Efficiency can be defined as a ratio of work (energy) output to work (energy) input.

Mathematically, the efficiency of a machine is given by the formula:

[tex]Efficiency = \frac{W_O}{W_I} \times 100[/tex]

Where:

Work can be defined as the amount of energy required to move an object from one point to another.

Hence, the work done by a machine is the product of the perpendicular force acting on the machine and the distance it covers or travels.

Ideally, the work output of a machine is highly dependent on its efficiency and as such, it is a factor which increases as the efficiency of a machine increases
