Answer:
The net ionic equation for the reaction of solid iron with aqueous copper sulfate:
Explanation:
Solid iron = Fe
Copper sulfate =
In an aqueous solution of copper sulfate we have copper (II) ions and sulfate ions.
In an aqueous solution of ferrous sulfate we have ion (II) ions and sulfate ions.
Cancelling out the common ions from both sides, we get the net ionic equation:
The answer is (B) decreasing the pressure on the gas, as Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure.
Removing some of the gas from the sample is the change that most likely results in a decrease in the volume of the gas, rather than an increase. This is because decreasing the amount of gas in the sample will reduce the total volume of the gas.
On the other hand, cooling the gas will typically cause it to contract, reducing its volume. Similarly, decreasing the pressure on the gas will typically cause it to expand and increase in volume.

Explanation:
As we all know that like disolves in like solvent.
Here both water and Ethanol are polar. Hence Ethanol soluble in water.
Moreover, both forms intermolecular hydrogen bonds. It enhances the solubility of ethanol.
Both water and Ethanol are called as associate liquids. Hence solubility is more.
Alcohols have higher boiling point than other hydrocarbons due to their polarity and from the fact that they form very strong intermolecular hydrogen bonding. This is due to the large difference in their electronegativity that forms between the oxygen and the hydrogen atom.
B. fluorine
C. hydrogen
D. nitrogen
E. aluminum
2) 0.101 kg Ti into atoms
Answer:
The answer to your question is below
Explanation:
1) 0.143g of Mg into atoms
- Look for the atomic number of Magnesium in the Periodic table
Atomic number = 24.31 g
-Use the Avogadro's number to find the number of atoms
24.31g ------------------- 6.023 x 10²³ atoms
0.143 g ----------------- x
x = (0.143 x 6.023 x 10²³) / 24.31
x = 8.613 x 10²² / 24.31
x = 3.54 x 10²¹ atoms
2) 0.101 kg of Ti into atoms
-Look for the atomic number of Titanium in the Periodic table
Atomic number = 47.87 g
-Use the Avogadro's number to find the number of atoms
47.87 g --------------------- 6.023 x 10²³
101 g ---------------------- x
x = (101 x 6.023 x 10²³) / 47.87
x = 6.08x 10²⁵ / 47.87
x = 1.27 x 10²⁴ atoms
A. outer core.
