The mass of NaCl produced is 0.117 g.
<h3>What is the pH?</h3>
The pH of a solution is what tells us if the solution is acidic or basic. The solution is acidic if the pH of the solution is less than 7.
1) pH = - log(3.5 x 10^-5 M)
= 4.45
Thus the solution is acidic.
2) We can see that the concentration as given is the concentration of OH^-
[OH ] = 4.0 x 10^-3 M
pOH = -log (4.0 x 10^-3 M)
pOH = 2.39
pH = 14 - 2.39
pH = 11.61
The equation of the reaction is; 
Number of moles of NaOH = 0.40 M * 10/1000 = 0.004 moles
Number of moles of HCl = 0.20 M * 10/1000 = 0.002 moles
We can see that HCl is the limiting reactant
Mass of NaCl produced ;
0.002 moles * 58.5 g/mol = 0.117 g

Answer:
Have you ever seen a "shooting star" race across the sky at night? Shooting stars are meteors zooming at high speed through Earth's atmosphere and burning up along the way from friction. And right now is one of the best times to see them in person. The Perseids, which are impressive meteor showers that happen each year from mid-July to late August, have their peak activity around August 11 to 14. They're caused by Earth traveling through debris from the Comet Swift-Tuttle. Luckily, most meteors are tiny and burn up before hitting the ground. But if a meteor doesn't disintegrate, what's its impact on Earth? In this activity you'll explore how a meteorite’s size is related to the size of the crater it makes on impact.

The corect answer is d. all of the above. The complete explanation is given below.
Explanation:
A Material Safety Data Sheet (MSDS) is a document with a description about potential hazards (health, environment, reactivity, etc.), physical properties, how to storage and how to manipulate and work safely with a given chemical product or substance. These kind of documents are standarized to a correct interpretation of final user. When someone purchased a chemical, chemical supply companies must provide the respective MSDS. However this kind of label are not legally required to be accurate.
The values of N, log N and ln N are all worked out below.
We have the number N as 8.99
hence;
1) lnN = ln(8.99) = 2.196
log N = log (8.99) = 0.954
2) If we have ln N as 3.949
N = e^3.949 = 51.88
So;
log N = log (51.88) = 1.715
3) log N = 0.134
N = Antilog (0.134 ) = 1.36
ln N = ln (1.36) = 0.307
