Answer:
Explanation:
Hello.
In this case, the first step is to compute the moles of copper (II) chloride (molar mass: 134.45 g/mol) in 2.0 g as follows:
Thus, since one mole of copper (II) chloride contains 1 mole of copper (its subscript) and 2 moles of chloride (its subscript), those moles are respectively:
Therefore, the concentrations (in molar units) considering the volume in liters of the solution (0.500 L for 500 mL) are:
Best regards.
Answer:
Gold.
Explanation:
Because gold has a lower specific heat than aluminium.
Oxygen proton number is 8 so its 2.6 so it have 6 valence electron
Answer is: A. The independent variable is changed to see its effect on the dependent variable while all other conditions are unchanged.
The two main variables in an experiment are the independent and dependent variable.
Dependent variable is the variable being tested and measured in a scientific experiment.
Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.
