<h2>C</h2>
Explanation:
The atomic number of S is 
So,number of electrons in S is
The electronic configuration of S is 
The orbital electronic configuration of S is 
So,the number of orbitals involved is 9.
Answer is: variables that were manipulated during the experiment.
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.
Laboratory room number is the least important.
Answer:
Explanation:
Hello,
In this case, given that 1 gal equals 4 qt, 1 qt equals 0.9464 L and 1 L equals 1x10⁹ nL, the dimensional analysis turns out:
Best regards.
Given
Mass number of isotope = 63
Number of neutrons = 33
So number of protons = 63 - 33 = 30
Hence atomic number of metal = 30
thus metal is = zinc
now as it is forming cation with 28 electrons it means it has lost two electrons so it must have a dipositive charge
the symbol of metal ion will be
Zn^+2
Answer:
gold is metal which is a very good conductor for electric current and most chips are made out of it.
