Well homogenous is the same, or similar. and heterogenous is when the substance is different. like gases, liquids, and solids. Hope that helps some.
Answer: 1 mol of potassium phosphate.
Explanation:
Find the molar mass of potassium phosphate.
Equation of potassium phosphate = K3PO4
The molar mass of K = 39.10 g/mol, P = 30.97 g/mol, O = 16.00 g/mol (use periodic table for these values).
Then add them up together based off of the equation.
3(39.10 g/mol) + 30.97 g/mol + 4(16.00 g/mol) = 212.27 g/mol
Multiply the 212.26 grams by the molar mass (unit conversion method).
= 1.00 mol
There is 1 mol of potassium phosphate.
Answer:
Double-Replacement Reactions
Explanation:
KOH + HNO3 -> H2O + KNO3
This is a double replacement reaction
The anions are "traded" and two new compounds are produced
(a liquid and a salt)
AL2o3 also known as Aluminium oxide is a chemical compound consisting of Aluminium and oxygen, hence AL2o3
