Answer:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Explanation:

The first two period elements can form maximum 4 covalent bonds. However, third or higher period elements can make higher number of bonds for example; SF6.

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

Answer:

The atmosphere and Earth's interior are layered by density. The differentiation between these layers is due to processes that took place during the early stages of Earth's formation (ca. 4.5 billion years ago). At this time, melting would have caused denser substances to sink toward the center while less-dense materials would have migrated to the crust.

Gravity pulls more strongly on denser materials so denser materials are at the center of things.

Explanation:

Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal core has convection, which generates the magnetic field.

Denser materials are in the centre of the universe because they are more powerfully pulled toward the centre by gravity.

The force that pulls items toward the centre of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

The mass of the Earth is what creates gravity. The total gravitational force of all of its mass acts on the weight in your body. What gives you weight is that. Additionally, you would weigh less than you do now if you were on a planet with a lower mass than Earth.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

Therefore, denser materials are closer to the centre of the universe because gravity is more drawn to them.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2

The force exerted on the parked car by the moving car is –30000 N

To solve this question, we'll begin by calculating the deceleration of the moving car. This can be obtained as follow:

Initial velocity (u) = 10 m/s

Final velocity (v) = 0 m/s

Time (t) = 0.5 s

[tex]a = \frac{v - u}{t} \\\\ a = \frac{0 - 10}{0.5}\\\\a = \frac{- 10}{0.5}[/tex]

Finally, we shall determine the force exerted by the moving car on the parked car. This can be obtained as follow:

Mass of moving car (m) = 1500 Kg

Acceleration (a) = - 20 m/s

F = ma

F = 1500 × (-20)

NOTE: The negative sign indicate force is in opposite direction to the parked car.

Therefore, the force exerted on the parked car by the moving car is –30000 N

Explanation:

The density of the metal beads is 12.47 g/mL (option c).

1. Determine the mass of the metal beads:

  Mass of beaker + metal beads = 205.5 g

  Mass of empty beaker = 82.0 g

  Mass of metal beads = (Mass of beaker + metal beads) - (Mass of empty beaker)

                    = 205.5 g - 82.0 g

                    = 123.5 g

2. Determine the volume of water displaced by the metal beads:

  Initial volume of water in the graduated cylinder = 60.9 mL

  Final volume of water in the graduated cylinder = 70.8 mL

  Volume of water displaced = Final volume - Initial volume

                           = 70.8 mL - 60.9 mL

                           = 9.9 mL

3. Calculate the density of the metal beads:

  Density = Mass / Volume

  Density = 123.5 g / 9.9 mL

  Density = 12.47 g/mL

Therefore, the density of the metal beads is 12.47 g/mL (option c).
