2N2 + 3O2 ---> 2NO + 2NO2
You should do it based on moles and not grams.
1.14 g O = 0.071 moles O
1 g N = 0.071 moles N
So in NO2 you need 2 moles O for each mole of N
1 g N = 0.071 moles, so you need 0.071 x 2 moles of O = 0.0.142 moles O
0.142 moles O x 16 g/mol = 2.27 grams of O. So, you are actually correct because your answer is 2.28 grams. I just prefer to work it out in moles so it makes perfect chemical sense.
Answer:
Low melting point
Explanation:
Transition metals have the following properties:
Conductivity (Electrical and Thermal)
Malleability (You can hit it with a hammer to mold it)
High melting point
Answer:The solar energy that we receive through solar radiation is directly or indirectly responsible for aspects as important to life as: Photosynthesis in plants; maintaining a planet temperature compatible with life. of the wind. The solar energy that reaches the earth's surface is 10,000 times greater than the energy currently consumed by all
Explanation:
ANSWERS:
Group 2 metal carbonates, nitrates and hydroxides decompose to heat to give the corresponding metal oxide and release CO2, NO2 and O2, and H2O respectively. The thermal stability increases down the group as theionic character of the compounds increases down the group.
