The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products.
Those ratios are fixed and when the reagents react do it in the same proportion and yield the products in the same proportion of the coefficients.
Then, the coefficients are the basis for the calculations of the amount of substances that react and the amount of substances that are formed as result of the reaction.
The new temperature is 337.21 K when the pressure was reduced to 101.3 kPa from 150.2 kPa at 500 K.
Explanation:
Data given:
volume of the container = 100 ml
initial pressure on the container P1 = 150.2 kPa
Initial temperature of the container, T1 = 500 K
final temperature of the container, T2 = ?
Final pressure on the container P2 = 101.3 kPa
from the data provided, we will use Gay Lussac's law to calculate the final temperature:
rearranging the equation,
T2 =
Putting the values in the equation:
T2 =
T2 = 337.21 K
thus, the final temperature of the container is 337.21 K
Potassium Recipients of massive transfusions may therefore develop electrolyte disturbances, with hypocalcemia, hypomagnesemia, and hyperkalemia most commonly reporte
Answer & Explanation:
The given number above, 0.002353, may be rounded to only two significant figures by adding 1 to the 3 which is in the fourth place of the decimal position. This becomes, 0.0024. Addition of 1 was done because the number that follows 3 in the original number is 5.
