ivanzaharov [21]3 years ago
3 0

Answer:

I hope this helps

Explanation:

Lewis symbols, which are also known as Lewis dot diagrams or electron dot diagrams, are diagrams that represent the valence electrons of an atom. Lewis structures, also known as Lewis dot structures or electron dot structures, are diagrams that represent the valence electrons of atoms within a molecule.

The melting point of copper is 1084°C. How does the energy of the particles in a certain amount of liquid copper compare to the
ipn [44]
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately 5 times compared to that of water.

An object has a mass of 4 grams and a volume of 2 cm3. What is the density of the object
kolbaska11 [484]

Answer:

<h3>The answer is 2.0 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 4 g

volume = 2 cm³

We have

density =  \frac{4}{2}  \\

We have the final answer as

<h3>2.0 g/cm³</h3>

Nitrogen gas effuses through an opening 1.59 times faster than an unknown gas.
Elodia [21]
A) Nitrogen has an ATOMIC mass number of 14, but nitrogen gas consists of N₂ molecules, so the mass to use in this problem is 28 g/mol. Rates of effusion ∝ 1/√(mass), so 

<span>√(mass unknown) /√28 = (rate N₂ effusion)/(rate unknown effusion) = 1.59 </span>
<span>∴ mass unknown = (1.59)²(28) = 70.78 g/mol </span>

<span>B) One possible gas that comes close for this mass is NF₃.</span>

mestny [16]

Answer:

One significant difference between gases and liquids is that <u>a gas expands to fill its container.</u>

Explanation:

One of the biggest differences between liquids and gases is that liquids have a defined volume and gases do not. A gas has no defined shape or volume, it acquires the shape and volume of the container in which it is located. It is the tendency of gases to increase in volume due to the force of repulsion that works between their molecules.
