Which elements are the most reactive and why?

Answers

Answer:

Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Hope that helps.

Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.

Two atoms of element Q mixed with element E

Answers

Both the elements combine together due to incomplete outermost shell.

Two atoms of element Q mixed with element E in order to achieve stability because both the elements have incomplete outermost shell which make them very reactive. In element E we can see that it has 7 electrons while on the other hand, element Q has 5 number of electrons.

For gaining stability, each element has to reach 8 electrons so that's why both the elements react with each other and get stability so we can conclude that both the elements combine together due to incomplete outermost shell.

Given that the molar mass of NaCl is 58. 44 g/mol, what is the molarity of a solution that contains 87. 75 g of NaCl in 500. ML of solution? Use Molarity equals StartFraction moles of solute over liters of solution EndFraction. 0. 333 M 0. 751 M 1. 50 M 3. 00 M.

Answers

Answer:

Explanation:

Given that the molar mass of NaCl is 58.44 g/mol, we want to determine the molarity of a solution that contains 87.75 g of NaCl in 500. mL of solution.

Recall that molarity is given by:

[tex]\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ liters soln.}}[/tex]

Therefore, we can convert the amount of NaCl in the solution to moles of NaCl and the volume from milliliters to liters:

[tex]\displaystyle \begin{aligned} \text{M} & = \frac{(87.75 \text{ g NaCl})}{(500. \text{ mL soln.})} \cdot \frac{1 \text{ mol NaCl}}{58.44 \text{ g NaCl}} \cdot \frac{1000 \text{ mL soln.}}{1 \text{ L soln.}} \\ \\ & = 3.00\text{ } \frac{\text{mol NaCl}}{\text{ L soln.}} \\ \\ & = 3.00 \text{ M} \end{aligned}[/tex]

Hence, our answer is D.

how many moles are in 8.32 × × times 10^24 molecules of co2?

Answers

Answer:

13.8 moles

Explanation:

You know that in a mole you have 6.022x10²³ something in this case of molecules. By knowing that by each mole you have 6.022x10²³ molecules, then you can establish the factor of conversion:

8.32x10²⁴molec of CO2 x 1 mol/6.022x10²³ molec of CO2

You divide 8.32x10²⁴/6.022x10²³ and you get 13.81 moles.

GRINDING:

Grinding is one of the processes that occur during the digestion of food molecules into simpler substances.

Grinding of food molecules occurs in the mouth with the aid of the teeth, which is used to chew.

However, the process of grinding is a physical change because it does not result into the formation of new substances or change the chemical constituents of the food.
