A scientific experiment requires that the temperature be lowered at a steady and gradual rate. The beginning temperature is 34°
1 answer:
The linear equation formed can be given as
Linear function is the relationship between the variable, with the graph being a straight line. The equation for a linear function is given as:
The initial temperature of the experiment is given as 34 degree Celsius and is given by t.
The time after which temperature is measured is t.
The time for which the lowering observed is 2 degrees per day.

Answer:
A. fluorine, 1.79 moles
Explanation:
Given parameters:
Mass of carbon = 87.7g
Mass of fluorine gas = 136g
Unknown:
The limiting reactant and the maximum amount of moles of carbon tetrafluoride that can be produced = ?
Solution:
Equation of the reaction:
C + 2F₂ → CF₄
let us find the number of the moles the given species;
Number of moles =
C; molar mass = 12;
Number of moles = = 7.31moles
F; molar mass = 2(19) = 38g/mol
Number of moles = = 3.58moles
So;
From the give reaction:
1 mole of C requires 2 moles of F₂
7.31 moles of C will then require 2 x 7.31 moles of F₂ = 14.62moles
But we have 3.58 moles of the F₂;
Therefore, the reactant in short supply is F₂ and it is the limiting reactant;
So;
2 moles of F₂ will produce mole of CF₄
3.58 moles of F₂ will then produce = 1.79moles of CF₄
