B. Density
Density = mass/volume because it’s basically the concentration of mass. How much matter takes up the space. If you pack more matter into less space, it is more dense.
Answer: A=1, B=3, C=12
Explanation:
For this problem, you will need to know your unit conversions. There are 3 ft in 1 yard. Knowing this, we can find A, B, C.
For A and B, we know that we want to cancel out ft so the answer can be in yards. To do so, we need to put B=3 and A=1.
Now that we know the unit conversion, we can directly solve.
36 ft×(1 yd/3 ft)=12 yd
Our final answer is A=1, B=3, C=12.
Answer:
The H+ concentration is 
Explanation:
We know that for any solution,
pOH + pH = 14
Given,
pOH = 9.70,
Therefore using formula,we get,
pH = 14 - pOH,
pH = 14 - 9.70;
pH = 4.30
We also know,
If Concentration of H+ in a solution in C,
Then,
pH = -log(C) ------(Formula 1) and C = 
----(Formula 2)
Therefore,
using formula 2, we get,
C =
C = 
M.
Therefore concentration of H+ in the given solution is
Answer:
False
Explanation:
Reactants are starting materials and are hence located at the left hand side of the equation while products are located at the right hand side.
