Answer:
Calcium nitrate is soluble in water and dissociate into ions whereas calcium carbonate is insoluble and water and do not form ions.
Explanation:
An electrolyte is a substance which conducts electricity in molten form or when dissolved in water.
The ability of an electrolyte to conduct electricity is due the movement of charged particles called ions. The ions are of two types: negatively charged ions called anions and positively charged ions called cations.
Calcium nitrate is a soluble in water, and when dissolved in water produces two ions; negatively charged nitrate ions,NO₃⁻, and positively charged calcium ions, Ca²⁺. These ions enable it to conduct electricity.
Calcium carbonate on the other hand is insoluble in water, and thus, do not produces any ions capable of carrying current.
Either covalent or ionic... they are nonmetals meaning that the are a component in both types of compounds
Answer:
150K is 253.67°F
Explanation:
There is a simple formula to convert from Kelvin to Celsuis;
C° = K - 273.15
<h3> C = 150 - 273.15 </h3><h3> C = -123.15</h3>
Then you would convert Celsuis into Fahrenheit using the formula:

<span>Pure substances can be either elements or compounds. Mixtures can be eitherhomogeneous or heterogeneous. ... Sometimes it can be difficult to tell the difference between a compound and a homogeneous mixture based solely on appearance. Consider gasoline.</span>
I think the correct answer from the choices listed above is option 3. The atomic mass of an element is defined as the weighted average mass of that element's naturally occurring isotopes. <span>The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.</span>
