The accurate measurements are near the center. To determine if a value is accurate compare it to the accepted value. As these values can be anything a concept called percent error has been developed. Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value.

If approximately equal volumes of an acid and a base of equal strengths are combined, the resulting solution should have a pH of
Masja [62]

Answer : The resulting solution will have a pH of 7.

Explanation:

Whenever acid and base reacts with each other to form water molecule is called Neutralization reaction. This water molecules is formed from the  hydronium ion (H^+) from acid and hydroxide ion(OH^-) from base.

When the equal volumes of acid and base of equal strength are combined, the resulting pH of the solution becomes 7.

The pH 7 value means that the solution is neutral.

Select the correct answer. Which statement best describes how chemical equations demonstrate conservation of mass? OA The number
timofeeve [1]

Answer: C. The number of atoms of each element is the same on each side of the equation.

Explanation:

The Law of Conservation of Matter shows that it is not possible for matter to either be created nor for it to be destroyed so the number of atoms of each element on the reactant side of the equation must equal the number of atoms in each element on the product side of the equation.

This is why the following equation is incomplete:

H₂ + O₂ ⇒ H₂O

The oxygen atoms are not the same on either side.

Equation will therefor have to be balanced which will make it:

2H₂ + O₂ ⇒ 2H₂O

Notice now that atoms are the same on both sides.

The ________ ion is represented by the electron configuration [ar]3d2.
Tresset [83]
The Ti 2+ ions is  represented  by  electron  configuration  (Ar)3d2. Titanium is in  atomic  number  22  and  its  electronic  configuration  is  (Ar)3d2 4s2.  Titanium loss two  electron that  is  4s2 electrons  hence the  electronic  configuration ( Ar)3d2.  4s2 is  the  valence electron  hence  it   the  one   which  is  lost  to  form  Ti2+
