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.
They are two representatives of the sublevels/energy levels.
Explanation:
1 g = 1000 mg
1 liter = 1000 ml
In sol. 1000 ml, there is NaCl 8500 mg
In sol. 15 ml, there is NaCl 8500/1000× 15 = 127.5 mg
The thing i can think of is that they are both things that specify a number of objects
Answer : The ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2
Explanation :
The relation between the equilibrium constant and standard Gibbs free energy is:
where,
= standard Gibbs free energy = -14.1 kJ/mol
R = gas constant = 8.314 J/K.mol
T = temperature =
Q = reaction quotient
= concentration inside the cell
= concentration outside the cell
Now put all the given values in the above formula, we get:
Thus, the ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2
