Answer:
207g
Explanation:
Given compound:
Ca(ClO₃)₂
Equivalent mass is the
The equivalent mass can be derived by summing the molar masses of each atom
Molar mass of Ca = 40
Cl = 35.5
O = 16
Now solve;
Molar mass = 40 + 2(35.5 + 3(16)) = 207g
Answer:
Chemical change
Step-by-step explanation:
A change in colour indicates that a new substance with different properties (colour) has been formed. This is a chemical change.
A. is <em>wrong</em>. A physical change does not usually cause a change in colour.
B. is <em>wrong</em>. No new gas or solid was formed,
C. is <em>wrong</em>. There is a colour change, not a temperature change.
Answer:
There are 1.260 moles for every 300.0 grams of Uranium
Explanation:
Many homeowners treat their lawns with CaCO3(s) to reduce
the acidity of the soil. The net ionic equation for the reaction of CaCO3(s)
with a strong acid, HCl (I chose HCl because it is a strong acid) is CaCO3(s) +2
HCl(aq) → CaCl2(s) + H2O(aq) + CO2(g).
