Answer:
74.566
Explanation:
C6H6 + 02 =6CO2 + 3H2O
2C6H6 + 15O2=12CO2 + 6H2O
mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol
mass conc = 2x78=156
mm CO2= 12+(16x2)=
12+32= 44gram/mol
mass conc of CO2 = 12x44
= 528
from The equation
156g of C6H6=528g of CO2
22.031g of C6H6=Xg of CO2
therefore, Xg=
22.031 x 528/ 156
= 74.566g
Answer:
Explanation:
BNCT therapy consists in the irradiation of the atoms of ¹⁰B that are contained in the tissue that has the tumor cells, with thermal neutrons to produce alpha particles and ⁷Li nucleus, according to the following nuclear reaction:
<em>Since the tissues also contain H and N atoms, the neutron irradiation produces secondary reactions in which proton particles and gamma radiation are produced:</em>
I hope it helps you!
I think the correct answer among the choices listed above is the second option. The observation which illustrates the law of conservation of mass is that wh<span>en 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced. Other choices doesn't shows that mass in is equal to the mass out.</span>
Catastrophism is a theory that stated that earth was shaped by a suddentmassive violent events that happened within a short period of time.
Uniformitarianism, on the other hand, is a theory that stated earth was shaped by slow and gradual events over a long period of time, which could take millions of years.
Answer:
Sulfur
Explanation:
You find the identity by looking at the number of protons. The number of protons never change for an element.
