Hello!
The balanced equation for the
neutralization of KOH is the following:
HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)
To calculate the
volume of HCl required, we can apply the following equation:
So, the required volume of HCl is
541,54 mLHave a nice day!
Answer:
A chemical change occurred, a gas and precipitate was produced
Explanation:
From the question , we are informed of science lab, where Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom.
In this case the change that took place is chemical change ( is one where new product are formed after two substance react) the bubbles that is produced signify the presence of gas in the product, white solid formed is reffered to as a precipitate( which is reffered to as solid that is been formed from a particular solution).
1s2 2s2 2p1
fifth electron is in 2p orbital
so answer is 2 2 -1 -1/2 , or 2 2 -1 1/2
*1/2 and -1/2 are spins, so they are interchangeable when writing the first electron in the ml
You can consider the density
of the water. Thus, in order to properly measure the mass of a liquid, we can
first get the volume and density of the liquid material or substance.
We can firstly utilize the
formula to get the mass from deriving the set formula of density to mass:
Since density is mass over the
volume,

Mass:20g
Mole=20/[2(23)+16]
=0.32 mil
