Answer:
The correct option is: C ) 14.4 lb
Explanation:
The standard International unit of mass is kilogram, kg. Other commonly used units of mass are grams (g), tonne (t), pounds (lb).
The mass of 500 mL liquid mercury is 6.53 kg.
Since, 1 kg = 2.20462 lb ≈ 2.205 lb
Therefore, the mass of 500 mL liquid mercury in pounds = 6.53 × 2.20462 = 14.39619 lb ≈ 14.4 lb.
PV = nRT
Where:
P = pressure in atm = 700/760 = 0.9211atm
V = volume = 8.29L
R = gas constant, 0.08206 atm-L/mol-K
T = temperature in Kelvin = 200 + 273 = 473
n = numbers of moles = Mass/molar mass
mass of the compound = 30.5
we can rewrite the equation above as
PV = (Mass)/(Molar mass) * RT
Answer:
the answer is 5⁷
Explanation:
it is 5 to the power of 7 because 5 is it base and then the 4 and 5 get added to get ur exponent
Answer:
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion. By losing those electrons, these metals can achieve noble gas configuration and satisfy the octet rule. (i found the answer in google hehe)
