atomic number = protons.
protons+neutrons=atomic mass.
170 (mass) - 41 (proton/number) = 129
that should be ur answer. I hope this helps!
((mass solute)/(mass solution)) * 100% =35%
mass CaCl2=0.35*352.5=123.4 g CaCl2
Tamam öğretmenim teşekkür ederiz çok güzel olmuş mu bir
One of the most likely products for the reaction would be 
<h3>Chemical reactions</h3>
The reaction between 
and 
yields 3 products which are (a precipitate), 
, and 
as shown by the equation below:
One of the products precipitates out of the solution to give the reaction a precipitation reaction look.

I believe the correct answer from the choices listed above is the first option. The compound that contains both ionic and covalent bonding is KOH or potassium hydroxide. It contains one covalent<span> (O-H) and one that is </span>ionic<span> (K-O). Hope this helps.</span>
