Okay to separate this mixture you will have to first use a magnet because the magnet will attract the iron filings out of the sand then you will remain with the sand and salt.
Next step is to add water to the sand and salt mixture the salt will dissolve in the water and the sand will not forming a heterogeneous mixture.Then using the method of filtration you can separate the sand from the salt solution leaving the salt solution
To separate the salt from the water use the method of evaporation this will enable you to get back the salt
In the end you should beable to have the sand,salt and iron filings separate.
Hope this was helpful to you.
Happy New Years !!! May your year be prosperous
Answer:
Steam and fog are gases
Water vapor example: Steam, fog, clouds
Explanation:
Steam and fog are both gas forms of water. Whenever a liquid is heated it evaporates and turns into a gas because the heat makes the liquid molecules move faster and spread out more, which then becomes a gas.
Water vapor is any form of water in a gas form.
The mass number of the element is 79 , atomic number is 34 and number of neutron is 45
<h3>What is Atomic Number ?</h3>
The number of proton which is used to separate one element from the other element is called Atomic Number. It is denotes as symbol Z.
What is Atomic Notation ?
The atomic number is the number of proton which is present in the nucleus of an atom. It is represented as 
.
where
X is the element
Z is the atomic number of that element.
A is the mass number of that isotope.
Now,
A = Z + N
79 = 34 + N
79 - 34 = N
45 = N
Thus from the above conclusion we can say that mass number of the element is 79 , atomic number is 34 and number of neutron is 45

Answer: CuI₂ + Br₂
Explanation:
1) The activity series F > Cl > Br > I means that F is the most active and I is the least active of those four elements (the halogens, group 17 in the periodic table).
The activity is a measure of how eager is an element to react compared to other elements in the series in a single replacement reaction.
2) Choice 1: CuI₂ + Br₂
Since the activity of Br is higher than that of I, Br will react with CuI₂, displacing I, which will be left alone, as per this chemical equation:
CuI₂ + Br₂ → CuBr₂ + I₂
Being I less active than Br, it cannot displace Br in CuBr₂.
3) Choice 2: Cl₂ + AlF₃
Being Cl less active than F, the former will not displace the latter, and the reaction will not proceed.
4) Choice 3: Br₂ + NaCl
Again, being Br less active than Cl, the former will not displace the latter, and the reaction will not proceed.
5) Choice 4: CuF₂ + I₂
Once more, being I less active than F, the former will not displace the latter, and the reaction will not proceed.
Answer:
0.007 mol
Explanation:
Step 1: Given data
Volume of acetaminophen: 0.8 mL
Step 2: Calculate the mass corresponding to 0.8 mL of acetaminophen
The density of acetaminophen is 1.26 g/mL.
0.8 mL × (1.26 g/mL) = 1 g
Step 3: Calculate the number of moles corresponding to 1 g of acetaminophen
The molar mass of acetaminophen is 151.16 g/mol.
1 g × (1 mol/151.16 g) = 0.007 mol
