Answer:- Titanium(III)oxide
Explanations:- Titanium is a transition metal and we know that transition metals shows variable oxidation states. Charge for oxygen is -2. While writing the chemical formulas, we use criss cross means the charge of the anion becomes the subscript of the cation. Similarly, the charge of the cation becomes the subscript of the anion.
Here, it is important that we use the simple ratio of the charges for their subscripts. For example if the anion and cation has equal charges then no subscripts are used.
The given chemical formula is . From this formula, the subscript of Ti is 2 which is the charge of oxygen atom. Similarly the subscript of O is 3 which is the charge of titanium atom.
While writing names for the compounds containing transition metals then the charge of the transition metal is indicated by writing roman numeral next to the name of the metal.
When oxygen is bonded to the metal ions then these compounds are named as oxides. As the charge of Ti is +3, the name of the compound is Titanium(III)oxide.
Answer:
<h3>F=132k.gm/s^2</h3>
Explanation:
<h3>F=m×a</h3><h3>f=22k.g×6m/s^2</h3><h3>f=132k.gm/s^2</h3>
Answer:
0.43mol of Mg(OH)2
Explanation:
the molar mass of Mg(OH)2 is 58.319g/mol so you divide 25 by that and get the amount of moles.
Hey there!
The molar mass of nitrogen is 14.007.
Convert grams to moles:
21.2 ÷ 14.007 = 1.51
The sample containing 21.2g of nitrogen contains 1.51 moles of nitrogen.
Hope this helps!
