Answer:
24.309 g/mol
Explanation:
To get the atomic mass, all we have to do is calculate with the masses of the three isotope, the real quantity present, taking account of the percent and then, do a sum of these three values. Like a pondered media.
For the first isotope:
23.99 * (78.99/100) = 18.95 g/mol
For the second isotope:
24.99 * (10/100) = 2.499 g/mol
For the last isotope:
25.98 * (11.01/100) = 2.86 g/mol
Now, let's sum all three together
AW = 18.95 + 2.499 + 2.86
AW = 24.309 g/mol
Answer:
False.
Explanation:
The chemical hazard label with colors indicates the specific class of hazard. Hazardous Materials Identification System is defined as the numerical hazard rating then incorporate the use of labels with colors.
Blue color: This sign conveys the health hazards of the material, means that long-term exposure to the material can cause the problems, for example kidney damage, and emphysema.
Red for color: This sign conveys the flammability hazards of the material.
Yellow for color: This sign conveys the instability hazards of the material.
(3) loses one electron and becomes positively charged
Lithium has one valence electron and Bromine has seven. Therefore Lithium will give up its one to Bromine for both to have an octet

T(K) <span>= T(°C) + 273.15</span>
So
to convert the boiling point of cyclopropane from degrees Celsius to kelvin:
