Answer:
When bonds between atoms break and new bonds are formed, creating a new Signs of a chemical reaction and therefore, the product is evident through physical gas atoms that make up its molecule and the covalent bonds between oxygen gas atoms attract and bond to form an ionic compound; magnesium chloride.
Explanation:
Answer:
The pH of the resulting solution is 12.52.
Explanation:
n = number of moles
V = volume of the solution in Liters
1)1 mol of HCl gives 1 mol of hydrogen ion.
Concentration of the hydrogen ion = 0.1 M
Volume of the solution = 10 mL = 0.010 L
Moles of hydrogen ions = = 0.001 mol
2) 1 mol of NaOH gives 1 mol of hydroxide ion.
Concentration of the Hydroxide ions = 0.2 M
Volume of the solution ,V'= 8 mL = 0.008 L
Moles of hydroxide ions ,n ' = 0.0016
1 mol of HCl neutralizes 1 mol of NaOH ,then 0.001 mol of HCl will neutralize 0.001 mol NaOH.
So left over moles of hydroxide ions in the solution will effect the pH of the solution:
Left over moles of hydroxide ions in the solution = 0.0016 mol - 0.0010 mol = 0.0006 mol
Left over concentration of hydroxide ions:
pH +pOH = 14
pH = 14 - 1.48 = 12.52
The pH of the resulting solution is 12.52.
Answer:
True
Explanation:
Permanent artificial, temporary artificial and natural. They are classified by the way in which they have achieved magnetism and by how long they remain magnetic.
Answer:
<u>D) A base.</u>
Explanation:
A base in chemistry is something that is slippery, hence it being a soap.
A mixture is easily separated like a salad where you can pick things out and a compound you are usually unable to undo.
