I think it will be letter A tbh
Hope this helps you out
Explanation:
When designing and conducting a scientific experiment then it is necessary to sequentially follows all the steps necessary for the experiment.
Also, it is required to identify independent variables, if any. On the other hand, it is required to address any confounding variables, so that it becomes mentioned the type or number of variables present.
Thus, we can conclude that when designing and conducting a scientific experiment:
- Identify the independent variable.
- Address any confounding variables.
Kc decreases as the temperature in molecules increase.
Answer:
170.38g is the mass of 1 mole of C₁₂H₂₆
Explanation:
To solve this question we must find the molar mass of the alkane C₁₂H₂₆. The molar mass is defined as the mass of one mole of a substance.
In 1 mole of C₁₂H₂₆ we have 12 moles of Carbon and 26 moles of Hydrogen. With the periodic table of elements we can know the molar mass of 1 mole of Carbon and 1 mole of hydrogen, and, thus, the molar mass of the alkane (Molar mass C = 12.01g/mol, H = 1.01g/mol)
<em>Molar mass C₁₂H₂₆:</em>
12C = 12*12.01g/mol = 144.12g/mol
26H = 26*1.01g/mol = 26.26g/mol
144.12g/mol + 26.26g/mol =
<h3>170.38g is the mass of 1 mole of C₁₂H₂₆</h3>
