Please be rightly informed that the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).
<h3>Fundamental quantities</h3>
These are quantities which forms the basic unit of measurement. The units of fundamental quantities are called fundamental units.
The three major fundamental quantities are:
Other fundamental quantities are:
- Temperature
- Amount of substance
- Magnetic flux
- Electric current
So therefore, the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).

Answer:
Explanation:
Hello!
In this case, since the reaction between nitrogen and hydrogen produces ammonia:
We can compute the volume of the container by using the ideal gas law at STP (1 atm and 273.15 K):
Next, since nitrogen and hydrogen are in a 1:3 mole ratio, we understand all the nitrogen and hydrogen are consumed and only ammonia remains at the end of the reaction in the following amount:
Thus, the final pressure turns out:
Best regards!
Answer:
Though soil pH generally ranges from 1 to 14, the optimum range for most agricultural crops is between 5.5 and 7.5. However, some crops have adapted to thrive at soil pH values outside this optimum range.
Answer: Hmmmmm that's crazy....
There are a couple of equations one could use for this type of problem, but I find the following to be the easiest to use and to understand.
Fraction remaining (FR) = 0.5n
n = number of half lives that have elapsed
In this problem, we need to find n and are given the FR, which is 1.56% or 0.0156 (as a fraction).
0.0156 = 0.5n
log 0.0156 = n log 0.5
-1.81 = -0.301 n
n = 6.0 half lives have elapsed

Just wanted to help. Hopefully it's correct wouldn't want to waster your time ;)
