CH4 + 02 → H20 + CO2
balance equation
CH4 + 2O2 → 2H2O + CO2
4 ÷ ( 12 + 4 ) = 0.25 mol
1 : 2
no mole of H2O = 0.25 × 2 = 0.5 mol
mass of H2O = 0.5 × ( 2 + 16 ) = 9g
The electric distance meter and extensometer are used to measure length between two points and tensile strength respectively.
Electronic distance measurement uses electromagnetic waves such as infrared light while extensometer place the object under stress.
<h3>What is Electronic distance measurement and extensometer?</h3>
Electronic distance measurement and extensometer are tools that can be used to Know the length between two points and tensile strength respectively using different techniques.
The extensometer usually places a sample under stress to determine the length of the material while Electronic distance measurement uses beam of infrared light.
