Element on the right side of the periodic table differ from the elements on the left side in that elements on the <em>right side are non metallic and tends to be gases at room temperature.</em>
<em> </em><u>Explanation</u>
In the periodic table there element in the right side , left side and those which are in between.
- Example of element in the right side is fluorine chlorine, neon, Argon among others.
- This element have higher effective nuclear charges and stabilize electrons more effectively.
- there electrostatic intermolecular forces are generally weak therefore they exist in liquid or gaseous state.
That would be the compound Ba(NO3)2. The Barium ion has a charge of 2+ so there are 2 NO3- ions in the formula to produce a neutral compound.
Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
Use conversion factors to calculate this answer. Since there are 1000 ml in a liter, this means that there is 95 mg of glucose in 0.1 liter. To add on, since there is 1000 mg in a gram, this means that there is 0.095 grams in 0.1 liters. 5 liters of blood is 0.1 x 50 = 5.0. Hence, you would need to multiply 0.095 x 50, which is equates to about 4.75 grams of glucose in 5.0 liters of blood.
Don’t forget the significant figures, 4.75 is rounded to 4.7 because the significant figures in this case is 2 sig figs (5.0 liters of blood).
