The knowledge of periodic table would be important in these three different careers such as medicine, pharmacology and engineering.

<h3>What is the importance of periodic table in following careers?</h3>

Periodic table is organised the whole elements vertically in groups and horizontally in periods with increasing atomic number.

The knowledge of arrangement of these elements serves alot of purposes in the following three different careers:

  • Medicine: The element, iron is an important metal in the periodic table used in treatment of low blood levels.

  • Pharmacology: The transition metals are useful in the field of pharmacology for the production of drugs. Example of such elements are chromium, manganese, cobalt, nickel, copper, and molybdenum.

  • Engineering: The information of elements in the periodic table helps engineers in designing of materials used for constructions.

Therefore, the knowledge of periodic table is very important in these three different careers such as medicine, pharmacology and engineering.

There are 342 g of sucrose in 1.00 mol of sucrose. What is the molar concentration (molarity) of a solution containing 171 g suc
AVprozaik [17]
For the answer to the question above, use these formulas in solving your problem and as a guide.
<span> 
MM = 342 (g/mol) </span>

<span>171 (g) / 342(g/mol) = x mol of sucrose </span>
<span>x moles of sucrose/ 1.25 L =  Molarity of soultion

How many electrons would an uncharged atom of nitrogen have
dybincka [34]
The atomic number represents the number of protons in an atom's nucleus. In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6.

A piston chamber filled with ideal gas is kept in a constant-temperature bath at 25.0°C. The piston expands from 25.0 mL to 75.0
larisa [96]

Answer : The work done by the system is, 2.2722 J

Explanation :

The expression used for work done in reversible isothermal expansion will be,

w=nRT\ln (\frac{V_2}{V_1})

where,

w = work done = ?

n = number of moles of gas  = 0.00100 mole

R = gas constant = 8.314 J/mole K

T = temperature of gas  = 25^oC=273+25=298K

V_1 = initial volume of gas  = 25 mL

V_2 = final volume of gas  = 75 mL

Now put all the given values in the above formula, we get:

w=0.00100mole\times 8.314J/moleK\times 298K\times \ln (\frac{75}{25})

w=2.722J

Therefore, the work done by the system is, 2.2722 J

For the reaction shown, calculate how many grams of each product form when the following amounts of reactant completely react to
stira [4]
This may help you
<span>You need to use some stoichiometry here. The only way to do that is if you're working in moles. Since you're given grams of Al, you can convert that moles by dividing by the molar mass. Then from looking at the coefficients in your equation, you can see that for however many moles of Al react, the same numbers of moles of Fe will be produced, but only half as many moles of Al2O3 will be produced. To go back to grams, multiply the moles of each product that you get by their molar masses!</span>
