pH is a symbolic representation of:
and for water we now that:
that means the text give us the information to calculate the concentration of protons and therefore the concentration of ions OH-:
therefore the concentration of OH- can be calculated:
but they are not asking about the concetration of OH- they ask about concentration of Ba(OH)2 and for that we need to know the disolution stechiometry
Whic mean the concentration of Ba(OH)2 is half the concentration of OH-:
The attraction between various combinations of atoms will produce BONDS..........
Answer:
Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes.
60mmHg = 1 atm
<span>1 mmHg = 1/760atm </span>
<span>610mmHg = 610/760 </span>
<span>= .80atm</span>
Answer:
B. 2g
Explanation:
So first you have to find the mole to mole ratio then convert it to grams if that makes sense. So the mole to mole ratio is 2 ammonia to 3 hydrogen gas. So then after you do that conversion you can solve for grams then. Sorry I am not that great at explaining.
