Functional Groups - Purdue University

Once we recognize that water contains an OH functional group, we can predict what might happen when sodium metal reacts with an alcohol that contains the same functional group. Sodium metal should react with methanol (CH 3 OH), for example, to give H 2 gas and a solution of the Na + and CH 3 O-ions dissolved in this alcohol.. 2 Na(s) + 2 CH 3 OH(l) H 2 (g) + 2 Na …

One half of a mole of atoms would contain how many atoms? A) 0.5 B) 3.011 × 1023 C) 6.022 × 1023 D) 6.022 × 1011.5 E) none of the above. The mass of 1 mole of carbon is the same as the mass of 1 mole of magnesium. D) Sodium metal reacts with water to form aqueous sodium hydroxide and hydrogen gas.

Sodium Element | History, Uses, Facts, …

Sodium has an atomic nuer of 1 and atomic mass of 22.98. It is placed in group 1 of periodic table as it has a single electron in its outer most shell that it readily donates, creating a positively charged ion, the Na+ ion. At room temperature Sodium is soft, silvery-white metal which can be easily cut with a knife. It is highly reactive.

Design an airbag that contains a total mass of 622.0 g of solid material and meets the design limitations below. NaN3 is acutely toxic. It is essential that all of the NaN3 is consumed. NaN3 is relatively expensive. It would be most cost effective to use as little as possible. Sodium metal is highly reactive and will ignite in the presence of

Chemistry Unit 1 Resit Past Paper …

May 2015 - Some airbags in cars contain sodium azide (NaN3). Sodium azide is made by reacting dinitrogen monoxide gas with sodium amide (NaNH2) as shown by the equation. 2NaNH2 + N2O --> NaH3 + NaOH + NH3 Calculate the mass of sodium amide needed to obtain 550g of sodium azide, assuming there is a 95.0% yield of sodium azide.

Chemistry Behind Airbags

Sodium azide (NaN 3) can decompose at 300 o C to produce sodium metal (Na) and nitrogen gas (N 2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN 3 to decompose. The nitrogen gas that is generated then fills the airbag.
