Answer: If I practice 30 minutes a day on my basketball skills, then I will get better at making baskets.

Explanation:

Number 1 can't be a hypothesis because it is a personal preference and that has nothing to do with hypothesis.

Number 2 has no actual factual basis for concluding that and considering that hypothesis are scientific guesses based on information you already know, that wouldn't make sense.

Therefore number 3 makes the most sense considering the fact that the more you do anything the more of a feel you get for it

Which of the following is defined as the mass of an atom based on the mass of an atom of carbon-12?
iogann1982 [59]
<span>This would be the atomic mass. In an atom of carbon-12, there are 6 protons and 6 neutrons at rest (electrons have a negligible mass and are usually not part of the overall mass calculation). All atomic masses are based off the measurements of this specific iteration of carbon.</span>

What do you think explains why the larger elements are able to form in a supernova explosion? Use evidence from the Supernova 10
lubasha [3.4K]

Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.

<h3>What is Supernova?</h3>

This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.

The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.

This is therefore the reason why it was chosen as the most appropriate choice.

Using VSEPR model, how is the molecular arrangement about the central atom (molecular geometry) for XeF4?
jeka57 [31]

Answer:

Square planar.

Explanation:

Hello,

In this case, it can be demonstrated that the central atom Xenon in XeF₄ has a sp³d² hybridization which means that its geometry is likely to be octahedral.  Nevertheless Applying by applying the valence shell electron pair repulsion (VSEPR) model to in order to minimize the repulsion among lone pairs, bond pairs and lone pair-bond pairs, we we realize repulsion is actually minimized when lone pairs are anti to one another and the fluorine atoms are in equatorial position, for that reason, the corrected and properly exhibited geometry or molecular arrangement of the compound turns out square planar. You can verify it on the attached picture.

Regards.

Is oxygen an element or a compound? Explain.
Margarita [4]
<h3><u>Answer;</u></h3>

Element

<h3><u>Explanation;</u></h3>

Oxygen is an element and not a compound.

Elements are substances that can't be split into simpler substances by chemical means. They include, hydrogen, oxygen, sodium, etc.

Compounds are substances that are made up of two or more elements e.g. water is a compound, since it is made up of oxygen and hydrogen element. Compounds unlike elements can be split into simpler substances by chemical means.
