The answer is the carbon cycle
Answer:
False it da answer i think
Explanation:
False .......
The atomic masses listed on the periodic table are a weighted average of an element’s isotopes.
It would float because candle wax is less dense than water because the oxygen in the water is heavier and smaller than carbon in the wax
Answer:
Let us write down the reaction equations for inorganic substances:
N2 + 3H2 = 2NH3 – redox reaction (ORR), ammonia was obtained;
4NH3 + 5O2 = 4NO + 6H2O – ОВР, nitrogen oxide was formed (2);
2NO + O2 = 2NO2 – ОВР, nitrogen oxide was released (4);
H2O + 2NO2 = HNO3 + HNO2 – OBP, nitric acid obtained;
2HNO3 + PbO = Pb (NO3) 2 + H2O – ion exchange, lead nitrate was formed;
2Pb (NO3) 2 = 2PbO + 4NO2 + O2 – OBP, oxygen was obtained.
The reaction products are of practical importance, for example, lead nitrate is the basis for obtaining pigments necessary for dyeing fabrics in the textile industry. These reactions show the connection of non-metals, hydrides, oxides, acids, salts.
