I see you have access to the internet. Google 'Kelvin to C', and input 251. You'll get -22.15.
Answer:
B) 
Explanation:
The total ionic equation contains all the species in the reaction in the ionic form.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
Spectator ions are also written in total ionic equations.
The chemical equation is:
The total ionic equation is -
Answer:
Stronger!
Explanation:
The <u>stronger</u> the forces among the particles in a sample of matter, the more rigid the matter will be.
<span>The symbol for hydronium ion concentration is H+. </span><span>There are quite a few
relationships between [H+] and [OH−]
ions. And because there is a large range of number between 10 to 10</span><span>-15</span><span>
M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, </span><span>[H+
][OH- ] = 10-14. From here we can derive the values of each concentration.</span>
No.
Electromagnetic waves can travel without a medium.
hope this helps and have a great day :)
