What state of matter can expand to fit the volume of a container

1 answer:

3 0

The liquid state of matter can do this, as its atoms aren’t as tightly connected as the ones in solids. Imagine you have a big pile of marbles. In this analogy, solids would be strong magnetic marbles, which, once formed, would keep their shape. Liquids would be like barely bonded marbles, basically loose, which would accomodate themselves to the bowl where they would be in. And gas would be floating marbles, flying around, spreading whenever empty space can be found.

- How many moles of S2 are needed to produce 1.50 moles of SO2 gas? S2 + 20, ----> 2802

matrenka [14]

Answer:

0.75 moles

Explanation:

S2 + 2O2 = 2SO2

From the reaction above,

We see that number of moles attached to S2 is 1 and number of moles attached to SO2 is 2.

Since we want to find how many moles of S2 are needed to produce 1.50 moles of SO2 gas

The answer is gotten by proportion;

Number of moles = 1/2 × 1.5 = 0.75 moles

I need help with balancing equations I'm doing homework and idk what to do here can you give me the answers please lol

It's pretty easy to balance equations! Basically you want to make sure that the number of each compound is equal on both sides of the arrow.

For example number one is

Fe + H2SO4 -> Fe2(SO4)3 + H2

A 3 in front of H2SO4 because there's a subscript of 3 on the right side.

Then a 3 in front of H2 because of the previous step.

Then add a 2 in front of Fe because of the 2 subscript in Fe2(SO4)3

Then add a 1 in front of Fe2(SO4)3 because you already have an equal number of each element.

2Fe + 3H2SO4 -> 1Fe2(SO4)3 + 3H2

I hope this explanation helps! You should really do your homework because practice is everything when it comes to chemistry. You'll need to know how to do it for exams.

The correct answer that explains similarities between metal and Metalloids as regards the question is They both conduct electricity

Metalloids can be regarded as elements that are similar to metals, this is because they posses valence orbitals which is described as highly delocalized over macroscopic volumes.

As a result of this they can serve as electrical conductors.

metalloids posses small energy gap which is located between the valence band as well as the conduction band, as a result of this they are considered as intrinsic semiconductors when compare to pure conductors like metal.

Example of metal is Calcium, sodium and that of Metalloids are silicon and germanium

Therefore, metal and Metalloids are similar because of their conductivity of electricity

A standard backpack is approximately 30cm x 30cm x 40cm. Suppose you find a hoard of pure gold while treasure hunting in the wil

Blizzard [7]

Explanation:

The dimensions of a standard backpack is 30cm x 30cm x 40cm

The mass of an average student is 70 kg

We know that, the density of gold is 19.3 g/cm³.

Let m be the mass of the backpack. So,

$\text{density}=\dfrac{\text{mass}}{\text{volume}}\\\\m=d\times V\\\\m=19.3\ g/cm^3\times (30\times 30\times 40)\ cm^3\\\\m=694800\ g\\\\\text{or}\\\\m=694.8\ kg\approx 700\ kg$

An average student has a mass of 70 kg. If we compare the mass of student and mass of backpack, we find that the backpack is 10 times of the mass of the student.
