Answer:It will go on until the concentrations will meet. Blood cells are composed mainly of water, it will make up the proportion of about 90% of water for whole body. ... Because of the difference in osmotic potential caused by the salt water solution, water will diffuse out of the red blood cells causing them to shrink in size.
Explanation:
Answer:
Explanation:
Method 1 proportion
1 mole of chromium is 52 grams
11.9 moles = x grams
1/11.9 = 52/x Cross multiply
x = 11.9 * 52
x = 618.8 grams
Now I have used an approximate mass for Chromium. The answer you get here is expected to reflect the weigth given on your periodic table Use that to get your answer. You should give a number very close to mine. Round to 3 places as in 619.
Method Two Formula
mols = given mass / molecular mass
11.9 = given mass / 51.9961 Multiply both sides by 51.9961
11.9 *51.9961 = given mass
given mass = 618.75
given mass = 619
Phorgum is an arrangment similar to the periodic table. We may arrange elements or compounds based on its properties. Arrangement can be made on the basis of rows, columns, ascending and descending order.
Answer: The metalloids are a unique group of elements that share properties of both metals and nonmetals.
Explanation: They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
Answer:
9.28 g/L
Explanation:
We will be using the ideal gas law to solve this problem:
PV = nRT where P is the pressure (atm)
V is the volume (L)
R is the gas constant 0.08205 Latm/Kmol
T is the temperature (K)
n is the number of moles
The number of moles is the mass divided by the molecular weight, and from here we can solve for the density. (Note here we use the atomic weight of radon since its is a monoatomic noble gas)
PV = m/AW RT ⇒ P = (m/V ) RT/AW ⇒ P AW /RT =D
0.950 atm x 222.0 g/mol / [( 0.08205 Latm/Kmol ) x 277 K ] = D
9.28 g/L = D
