I believe that the best answer to the choices given in your question is <span>C. The molarity of hydronium is lower than the molarity of hydroxide.</span>
I hope I have answered your question. Have a nice day ahead.
Answer:
To prevent the mixture from separating substances called emulsifiers can be added. These help to form and stabilise the emulsions, preventing or slowing the water and fat/oil from separating. ... The hydrophilic end of the emulsifier molecule is attracted to the water and the hydrophobic end is attracted to the fat/oil.
Answer: Sr
Explanation: Strontium electron configuration is [Kr] 5s2. It belongs to group 2 and period 5 of the periodic table.
Mass Molar of

Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of

= 120 + 62 + 128 = 310 g/mol
Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?
</span>Answer:
310 grams
Gamma rays
gamma rays has shortest wavelength which emits from the sun so it has highest energy because energy and wavelength are inversely proportional to each other.
