False, it is an example of an Ionic solid
Answer:
NASA uses rockets to launch astronauts and supplies to the International Space Station. Launching a rocket relies on Newton's Third Law of Motion. A rocket engine produces thrust through action and reaction. The engine produces hot exhaust gases which flow out of the back of the engine.
Explanation:
A pH of 7 is neutral, because a measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle (neutral) point.
Combustion is a chemical reaction in which a hydrocarbon reacts with oxygen to form carbon dioxide (CO2) and water (H2O). In other words, all the carbons get converted to CO2 while all the hydrogens get converted into H2O.
Incomplete combustion however, results in the formation of carbon monoxide (CO) and H2O.
Methane is a hydrocarbon with a molecular formula CH4. Thus complete combustion of methane can be expressed as-
CH4 + 2O2 → CO2 + 2H2O
