Answer: NaCl and H2O
Explanation: Products are on the right side of the arrow :)
Answer: gasoline, water, sea water, chloroform and mercury so B
Explanation:
Okay so we know that pOH + pH = 14, so if pOH is 0.253 the pH would be 13.747.
<span>And pH = -log [H+], so [H+] = 10^(-pH) -->This is just the antillog... </span>
<span>so [H+] = 1.791e-14, which would make sense for the strongly basic solution (so B is the correct answer) </span>
<span>Hope this helps...</span>
Answer:
The atomic mass of Si-30 is 29.955 amu
Explanation:
Step 1: Data given
Si-28 has an atomic mass of 27.9769 amu and a natural abundance of 92.2 %
Si-29 has an atomic mass of 28.9765 amu and a natural abundance of 4.67%
The atomic mass of Si is 28.0855 amu
Step 2: Calculate natural abundance of Si-30
100% - 92.2 % - 4.67% = 3.13 %
0.922 * 27.9769 + 0.0467 * 28.9765 + 0.0313* X = 28.0855
27.14790435 + 0.0313X = 28.0855
0.0313X = 0.93760
X = 29.955 amu
The atomic mass of Si-30 is 29.955 amu
Answer:
CaF2 > Ag2CO3 > Ag3(PO4)2 > Ba3(PO4)2
Explanation:
Ksp which is solubility product konstant shows equilibrium between a solids and its respective ions in a solution. And the lower it is the less soluble the ion compound will be. And for CaF2 we have the highest konstant and for Ba3(PO4)2 we have it the lowest.
