What is the correct formula that would result from the combination of the two ionic species?

Noble gases are unreactive because of their electronic structures. The kind of reasoning that states "if other elements could be

Goshia [24]

Answer:

C. Deductive reasoning

Explanation:

Deductive reasoning is a reasoning or logical process whereby a conclusion is drawn based on the belief of multiple premises that are generally assumed to be true. It is a logical process in which one or multiple statements reaches a logical conclusion.

In the question, the statement assumed to be true is that noble gases are unreactive because of their electronic structures.

The conclusion thus drawn from the premise is that if other elements could be made to achieve noble gases electronic structures (this is the reason why they are unreactive - the fact) they would be more stable.

Therefore, deductive reasoning moves from a wilder reasoning to a specific (narrower) reasoning.

A student plots the magnetic field of a bar magnet using a compass the student centers the bar magnet in the middle of a piece o

olga55 [171]

The diagram best shows the magnetic field around the bar magnet is the diagram in option B.

<h3>What is the magnetic field?</h3>

The magnetic field refers to the region in space where the influence of a magnet can be felt. We know that strength of magnet can be seen by following the magnetic lines of force. The more the magnetic lines of force, the stronger the magnetic field especially when the line are packed closely together.

Looking at the diagrams of the magnetic lines of force, it must be recalled that the magnetic lines of force runs from the north pole to the south pole and not the other way round.

Thus, the diagram best shows the magnetic field around the bar magnet is the diagram in option B.

What is the difference between nuclear fusion and nuclear fission?

True [87]

Answer:

[Fusion: Nuclei Fuse together and release energy] [Fission: Pressure and energy is released. This release of energy, is what causes the unstable atom to split to an isotope. I hope this helps!]

[isotopes can split too. At least some.]

Explanation:

Imagine you are trying to push something heavy, fusion is how you can join together and help each other to push this heavy material.

Fun fact! Heavier materials have more inertia against other forces acting on them.

You push harder, harder and harder! Until its pushed.

This will release a lot of energy which escalates to an extended length.

It might not be the finest example, it helped me to understand the basics.

Fission. Imagine having so much energy, in this case, try thinking of so many people in a tight space. What do you do? You will eventually start to escape and leave the room. This is the act of splitting the atom.

This won't be the same than how it was before.

Again, Energy is released (energy!!).

For anyone struggling with this, although it might not be the best idea, I would recommend researching the more advaced options for this topic.

This will give you a wide range of information which can develop your current knowledge about, "Nuclear Fission and Fusion."

It will be difficult, it definitely was for me when I was a child (starting to study science).

Just keep trying, you'll get it.

A 35.0 ml sample of 0.225 m hbr was titrated with 42.3 ml of koh. What is the concentration of the koh?

Lemur [1.5K]

Answer:

The concentration of KOH is 0.186 M

Explanation:

First things first, we need too write out the balanced equation between HBr and KOH.

This is given as;

KOH (aq) + HBr (aq) → KBr (aq) + H2O (l)

From the reaction above, we can tell that it takes 1 mole of KOH to react with 1 mole of HBr.

We use the acid base formular in calculating unknown concentrations. This is given as;

$\frac{CaVa}{CbVb} = \frac{na}{nb}$

where;

Ca = Concentration of acid

Va = Volume of acid

Cb = Concentration of base

Vb = Volume of base

na = Number of moles of acid

nb = Number of moles of base

KOH is the base and HBr is acid.

Hence;

Ca = 0.225

Va = 35

Cb = ?

Vb = 42.3

na = 1

nb = 1

Making Cb subject of formular we have;

$Cb = \frac{CaVaNb}{VbNa}$

Cb = (0.225 * 35 * 1) / (42.3 * 1)

Cb = 0.186 M
