 <span>1.Schrodinger's equation deals with the modern atomic theory. 
2. They are tested by many scientists. 
3. I am not sure on this one. 
4. It depends on the atomic weight of the boron. There are 5 protons for sure, but the number of neutrons depends on the isotope.</span><span>

How does the periodic table make it easier for the scientist to work with and study elements
ololo11 [35]

Answer:

The periodic table has gone through many changes since Dmitri Mendeleev drew up its original design in 1869, yet both the first table and the modern periodic table are important for the same reason: The periodic table organizes elements according to similar properties so you can tell the characteristics of an element just by looking at its location on the table

When can all the coefficients in a balanced equation represent volume ratios? when reactants and products are solids at stp when
Alexxx [7]

Answer: when reactants and products are gases at STP.


Justification:


1) STP stands for standard temperature (0°) and pressure (1 atm).


2) According to the kinetic molecular theory of the gases, and as per Avogadro's principle, equal volumes of gases, at the same temperature and pressure, have the same number of molecules.



3) Since the coefficients in a balanced chemical equation represent number of moles, when reactants and products are gases at the same temperature and pressure, the mole ratios are the same that the volume ratios, and then the coefficients of the chemical equation represent the volume ratios.

A student carefully placed 15.6 g of sodium in a reactor supplied with chlorine gas. When the reaction was complete, the student
BabaBlast [244]

Answer:

24.09 grams of chlorine gas reacted.

Explanation:

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

Moles of sodium chloride = \frac{39.7 g}{58.5 g/mol}=0.6786 mol

According to reaction, 2 moles of  NaCl are formed from 1 mole chlorine gas.

Then 0.6786 moles of NaCl will be formed from;

\frac{1}{2}\times 0.6786 mole=0.3393 mol

Mass of 0.3393 moles of chlorine  gas:

0.3393 mol × 71 g/mol = 24.09 g

24.09 grams of chlorine gas reacted.
