compounds, on the other hands can have their bonds broken with practical amounts of energy, such as the heat from a fire. Matter can be broken down into two.

Answer:

there gravitational force is very less to pull the weight of a person.

Two students who stand close to each other don't get pulled closer as a

result of gravitational force because the magnitude of the force is small.

Gravitational force acts on all objects on Earth but the force exerted is very

small as a result of the masses of the students being very small as to when

compared with that of the earth.

The large difference in mass of the student and earth is the reason why the

effect of the force is very little and unable to move them closer.

Based on the octet rule, phosphorus most likely forms a P³⁻ ion; option D.

The octet rule is a rule which describes the way in which atoms of elements behave in terms of electron arrangement or distribution in order to achieve stability.

The octet rule states that atoms of elements achieve stability when they have eight electrons in their valance shells.

It explains that atoms of elements will gain, lose or share a certain number of electrons in order to achieve the stable electronic configuration of the noble gases.

Phosphorus has five electrons in its valence shell and will accept three electrons in order to have an octet.

Answer:

The density of tin is 7.31 g/cm³.

Explanation:

Given that the formula of density is D = m/v where m represents mass and v is volume :

D = 16.52/2.26

D = 7.31 g/cm³ (3sf)

Answer:

-3.82ºC is the freezing point of solution

Explanation:

We work with the Freezing point depression to solve the problem

ΔT = m . Kf . i

ΔT = Freezing point of pure solvent - freezing point of solution

Let's find out m, molality (moles of solute in 1kg of solvent)

15 g / 58.45 g/mol = 0.257 moles of NaCl

NaCl(s) → Na⁺ (aq) + Cl⁻(aq)

i = 2 (Van't Hoff factor, numbers of ions dissolved)

m = mol /kg → 0.257 mol / 0.250kg = 1.03 m

Kf = Cryoscopic constant → 1.86 ºC/m (pure, for water)

0ºC - Tºf = 1.03m . 1.86ºC/m . 2

Tºf  = -3.82ºC

If the plants in yellow light grow faster during her experiment, Lana should repeat the experiment to confirm the result. Option D.

In science, hypotheses are tested using experiments. Two hypotheses are usually formed during the course of experimentation:

The null hypothesis is set up to either be accepted is found to be true or rejected if found to be false. The alternate hypothesis is just there for guidance.

Hypotheses being found not to be true does not always mean that the reverse will be true.

Thus, if a complete opposite is obtained during testing, the next thing would be to repeat the experiment in order to be double sure there was not a mistake.

Answer:

The Earth rotates on it's axis, and it takes 24 hours for the Earth to go all the way around. When the part of the Earth you're on is facing the sun, you have daytime. When the part of the Earth you're on is not facing the sun (facing the moon instead), you have nighttime.

There are 3 hydroxide ions bonded to each aluminum ion.

Aluminum belongs to the 13th group of the periodic table. It has 13 electrons in the orbitals. According to the electron distribution rule, there are 3 valence electrons in the aluminum ion.

In the molecule of hydroxide, the oxygen has 5 valence electrons capable of the formation of the double bond. The bonding of the hydroxide ion with the aluminum ion will complete the octet of Aluminum and oxygen by the formation of the double bond.

So Aluminum can form 3 bonds with hydroxide ions. 2 double contributing to 4 electrons and 1 single bond completing the octet of Aluminum.

Thus Aluminum can form 3 bonds with hydroxide ions.
