Explanation:
pH is the negative logarithm of hydronium ion concentration present in a solution.
If the solution has high hydrogen ion concentration, then the pH will be low and the solution will be acidic. The pH range of acidic solution is 0 to 6.9. The solution has more
than
If the solution has low hydrogen ion concentration, then the pH will be high and the solution will be basic. The pH range of basic solution is 7.1 to 14. The solution has more
than
The solution having pH equal to 7 is termed as neutral solution.The solution has equal concentration of

D. Rutherford's gold foil experiment
Well uncontrolled cell division can lead to cancer.
Hello!
The answer is: Al2S3(s)+6H2O(l)→2Al(OH)3(s)+3H2S(g)
Why?
Balancing equations is the process where we look for an equal number atoms for each element on both sides of a chemical reaction (reactants and products) in order to satisfy the Law of Conservation of Mass, which states that the mass is equal before and after the reaction.
So, we have to check the number of atoms for both sides of the reaction:
Reactants:
Al=2 atoms
S= 3 atoms
H= 2 atoms
O = 1 atom
Products:
Al = 2 atoms
O = 6 atoms
H = 6 + 6 atoms = 12 atoms
S= 3 atoms
So, we can see that there is a difference between the number of atoms of Hydrogen, there are 2 atoms for the reactants and 12 for the products, for the Oxygen we can see that there is just 1 atom for the reactants and 6 for the products.
To adjust the number of atoms of Hydrogen and Oxygen, we just need to multiply the compound by 6 (H2O)
Al2S3(s)+6H2O(l)→2Al(OH)3(s)+3H2S(g)
Therefore, we have the same number of atoms for each element on both sides of the chemical reaction.
Have a nice day!
If the volume of 425 grams was 48.0 cm³, simply divide
g/cm³ = 425 g/48 cm³ = 8.85 g/cm³
If using water in water displacement, 1 mL = 1 cm³
8.85 g/cm³ = 8.85 g/mL
This density is most closely aligned with that of B. Copper
Hope I helped!
