In the dark test tube carbon dioxide will be created, and will bring about the corrosiveness level in the water increment. In the light test tube carbon dioxide will be devoured, making the oxygen level ascent and make the corrosiveness level lessening.

An airplane model is an example of what type of model
Ksju [112]
TL;DR: The make of an aircraft is the name of the designer (for example, Boeing) and the model of an aircraft (also called the type) is the designation for the general design of the aircraft (for example, 737). It looks like "basic model" is just an older term for "model".

When a mixture of 12.0 g of acetylene (c2h2 and 12.0 g of oxygen (o2 is ignited, the resultant combustion reaction produces co2
valina [46]
The product of the complete combustion of any fuel (in this case, acetylene) are indeed water and carbon dioxide. 
Balancing the combustion reaction,
                           C2H2 +(5/2) O2 --> 2CO2 + H2O
The number of moles of C2H2 will be,
                        (12 g) x (1 mole/26 g) = 6/13 mole
Then, the number of moles of O2 is,
                         (12 g) x (1 mole/32 g) = 3/8 mole
Therefore the limiting reaction is the O2. Getting the amount of CO2 and H2O produced from balancing,
             CO2 = (3/8 moles) x (2 moles CO2/ 5/2 mole O2)(44 g/ 1 mole) = 52.8 g
             H2O = (3/8 moles) x (1 mole / 5/2 mole O2)(18 g / 1 mole) = 2.7 g
