A copper-gold alloy has a crystalline structure. All other options are mixtures which do not have crystalline structure.
Answer:
Thus the correct order would be a, b,d and then c
Explanation:
Rank of rock-forming minerals from most abundant to least abundant
1. Silicates
2. Carbonates
3. Oxides
4. Sulfates
Thus the correct order would be a, b,d and then c
Answer:
Explanation:
In simplest terms, the fastest moving ones that are closest to the surface.
Solution volume is 2.03 litres.
Explanation:
First number of moles of KNO3 present in 555.0 gm will be calculated.
n= mass of the substance/ mass of one mole of the substance.
n= 555/ 101.1032 ( molecular weight of KNO3 is 101.103)
= 5.4 moles
Now volume can be calculated by the formula:
M= n/V (M is the molarity, n is number of moles, V is the volume.)
= n/M
= 5.4/2.7
V = 2.03 liters.
Molarity is defined as the number of moles of a substance dissolved in 1 litre of solution.
Dilution is the process of “lowering the concentration of a solute in a solution by simply adding more solvent to the solution, such as water.” Diluting a solution entails adding more solvent without adding more solute.
<h3>How do you do dilution in math?</h3>
The number of dilutions is equal to the number of times the dilution factor will be multiplied by itself to equal the starting concentration divided by the final concentration. So with a dilution factor of 10, 10 to the X power is equal to the starting concentration divided by the final concentration.
<h3>How do you find the dilution of a solution?</h3>
You can solve for the concentration or volume of the concentrated or dilute solution using the equation: M1V1 = M2V2, where M1 is the concentration in molarity (moles/Liters) of the concentrated solution, V2 is the volume of the concentrated solution, M2 is the concentration in molarity of the dilute solution.
