A. dose
a dose is an amount, a response is an action, and pollutant and toxins are substances
Helium only possesses two valence electrons, while the other noble gasses posses eight
Answer:
helium=1,2atm
argon=2,8atm
Explanation:
partial is pressure exerted by each gas in a system since 30% is helium it means 70% is argon
argon =70%x4
helium=30%4
Answer:
44,901 kilo Joule heat is released when 
grams of ammonia is produced.
Explanation:
Moles of ammonia gas produced :
According to reaction, when 2 moles of ammonia are produced 9.18 kilo joules of energy is also released.
So, When 978.235 moles of ammonia gas is produced the energy released will be:
(negative sign indicates that energy is released as heat)
44,901 kilo Joule heat is released when grams of ammonia is produced.
Answer:
Chemical bond
Explanation:
Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.
