Answer:
0.0174 mol
Explanation:
Molarity is (moles of solute)/(liters of solvent). So, to find moles you need to multiply liters by molarity.
0.0437 L × 0.400 M = 0.0174 mol
The molecular formula is;
C4H10N2

the size of planets effects the amount of gravitational force each planet has, like jupiter, it has the most gravity.
Answer:
r = 3.61x M/s
Explanation:
The rate of disappearance (r) is given by the multiplication of the concentrations of the reagents, each one raised of the coefficient of the reaction.
r = k.
K is the constant of the reaction, and doesn't depends on the concentrations. First, let's find the coefficients x and y. Let's use the first and the second experiments, and lets divide 1º by 2º :
x = 1
Now, to find the coefficient y let's do the same for the experiments 1 and 3:
y = 1
Now, we need to calculate the constant k in whatever experiment. Using the first :
k = 4.01x10^{-3} M^{-1}s^{-1}[/tex]
Using the data given,
r =
r = 3.61x M/s
Answer:
To isolate the microorganism from the mice and determine if it is identical to the original unknown bacteria.
Explanation:
The next step to take is to isolate the microorganism from the mice and determine if it is identical to the original unknown bacteria.
Koch's postulates opines four criterion for which a microbe will be regarded as a causative agent of a disease if the following takes place.
That, the microorganism should be present in all the organism suffering from the disease. That these isolated microorganism are meant to be grown in a pure culture. After being grown in the culture, they should be reintroduced in the susceptible but healthy host. In conclusion, from the experimental host, the microorganism must be re-isolated. Hence, cultured to see whether it is identical to the original specific microorganism.
