Answer: 6.38 moles of are needed to react with 2.55 mol of
Explanation:
The balanced chemical reaction for the combustion of ethyne is:
According to stoichiometry:
2 moles of require = 5 moles of
Thus 2.55 mol of require = moles of
Thus 6.38 moles of are needed to react with 2.55 mol of
Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = min⁻¹
Initial concentration = 0.1 M
Final concentration = M
Time = ?
Applying in the above equation, we get that:-
<span>Ionic change’ is the closest answer - electric currents are conducted by ions in some substances, though not metal. The filament - metal wire - in an incandescent lightbulb glows with visible light because it is heated to a very high temperature by an electric current being passed through it. It is not a physical change because this generally involves change from one state to another — for example, solid to liquid. Chemical changes usually result from chemical reactions. </span>
