Answer:
4 ions
1 M³⁺ ion and 3 NO₃⁻ ions ( Where M³⁺ stands for the group 13 cation).
Explanation:
Group 13 elements are Boron , Aluminium, Galium, Indium and Thalium. When they form ionic compounds they can lose their three valence electrons to form a tripositive (+3) ion. Nitrate ion is a negative ion with a single negative(-1) charge. When these two form a compound 3 univalent negative nitrate ions must combine with one tripositive group 13 element to form a neutral compound. So the total no of ions is 4.
Answer:
Explanation:
Specific heat capacity can be defined as the heat required to raise the temperature of a unit mass of a substance by 1kelvin.
The heat capacity on the other hand, expresses the heat required to raise the temperature of asubstance by 1kelvin.
When we use specific heat capacity, we are particular about the amount of heat that would be needed to actually cause a temperature change in a unit of a substance. This suggests that even if we don't have a complete substance, we can be sure that by knowing the mass of a unit of a body one can easily estimate how much heat is required to raise its temperature. The specific heat is fundamental in calculating the heat capacity of a body. Without the value of the specific heat, we cannot evalutate the heat capacity of a body.
Answer:
pH = 10.113
Explanation:
Here, we can find pOH first:
pOH = ![-log([OH^-])](https://tex.z-dn.net/?f=-log%28%5BOH%5E-%5D%29)
= 3.886.
Then, we can find pH which is 14 - pOH. We then get the answer above.
