<span>The outer layers of the planet are gas. Deeper within the planet, pressure compresses the gases into a liquid. Some evidence suggests that Jupiter may have a small rocky core at its center.</span>
It would be 1A bc then the +1 charge will cancel out chlorine’s -1 charge
Answer:
Density, melting point. and magnetic properties
Explanation:
I can think of three ways.
1. Density
The density of Cu₂S is 5.6 g/cm³; that of CuS is 4.76 g/cm³.
It should be possible to distinguish these even with high school equipment.
2. Melting point
Cu₂S melts at 1130 °C (yellowish-red); CuS decomposes at 500 °C (faint red).
A Bunsen burner can easily reach these temperatures.
3. Magnetic properties
You can use a Gouy balance to measure the magnetic susceptibilities.
In Cu₂S the Cu⁺ ion has a d¹⁰ electron configuration, so all the electrons are paired and the solid is diamagnetic.
In CuS the Cu²⁺ ion has a d⁹ electron configuration, so all there is an unpaired electron and the solid is paramagnetic.
A sample of Cu₂S will be repelled by the magnetic field and show a decrease in weight.
A sample of CuS will be attracted by the magnetic field and show an increase in weight.
In the picture below, you can see the sample partially suspended between the poles of an electromagnet.
Answer:
C) C4H6 - Right answer
Explanation:
Let's combine the Ideal Gases Law with density to get the molecular formula for the unknown gas.
Density = mass / volume
1.06 g /L means that 1.06 grams of compound occupy 1 liter of volume.
P . V = n . R . T
Pressure in Torr must be converted to atm
760 Torr are 1 atm
371 Torr are __ (371 .1)/760 = 0.488 atm
0.488 atm . 1L = 1.06g/MM . 0.082 . 304K
(0.488 atm . 1L) / 0.082 . 304K = 1.06g/ MM
Mass / Molar mass = Moles → That's why the 1.06 g / MM
0.0195 mol = 1.06g / MM
1.06g/0.0195 mol = MM → 54.3 g/m
Now, let's use the composition
100 g of compound have 88.8 g of C
54.3 g of compound have ___ (54.3 . 88.8) /100 = 48 g of C
100 g of compound have 11.2 g of H
54.3 g of compound have __ (54.3 . 11.2)/100 = 6 g of H
48 g of C are included un 4 atoms
6 g of H are included in 6 atoms
The correct answer are:
#1. The measure of gravity on earth determines our weight
#2. The closer an object is to the center of earth, the greater the gravitational force on that object.
#3. Objects in a free fall are constantly picking up speed as they fall back to earth is true.
