Answer:
The answer is 2Fe(No3)3 + 3Na2CO3 -> Fe2(CO3)3 + 6NaNO3 .
Explanation:
Fe(lll) represents <em>I</em><em>r</em><em>o</em><em>n</em><em> </em><em>(</em><em>l</em><em>l</em><em>l</em><em>)</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em> </em><em>.</em>
NO3 represents<em> </em><em>N</em><em>i</em><em>t</em><em>r</em><em>a</em><em>t</em><em>e</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em> </em><em>.</em>
Na represents<em> </em><em>S</em><em>o</em><em>d</em><em>i</em><em>u</em><em>m</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em> </em><em>.</em>
CO3 represents<em> </em><em>C</em><em>a</em><em>r</em><em>b</em><em>o</em><em>n</em><em>a</em><em>t</em><em>e</em><em> </em><em>i</em><em>o</em><em>n</em><em>s</em><em>.</em>
Answer:
covalent bonds
Explanation:
Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
(if it is still confusing i have another way of explaining so jus let me know :)
Answer:
No, you can not calculate the solubility of X in water at 17 0C.
Explanation:
Solubility refers to the amount of a substance that dissolves in 1000 L of water.
To calculate the solubility of a solute in water, all the water is evaporated and the solid is carefully collected, washed, dried and weighed. The mass of solid obtained can now be used to calculate the solubility of the solute in water as long as there was no loss in mass of solid during the experiment.
In this case, the student threw away part of the solid that precipitated. As a result of this, the mass of solid obtained at the end of the experiment is not exactly the total mass of solute that dissolved in the solvent. Hence, the solubility of X in water at 17 0C can not be accurately calculated.
What is the concentration?
Answer:- atoms of boron.
Solution:- It's unit conversion problem that could easily be solved step by step.
Step 1:- grams to moles conversion-
2.00 g B (1 mol B/10.81 g B) = 0.185 mol B
Step 2:- mol to atom conversion-
0.185 mol B(6.022 x 10^23 atom B/1mol B) = atoms of B
