When you are dealing with mole calculations, whatever you do to one side of the equation you must also do to the other. .5Fe is 1/8th of 4Fe, so in order to determine what it will yield you must divide the given amount of Fe2O3 and divide THAT by 1/8th, leaving you with .25 mol of Fe2O3.
According to the second law of thermodynamics, heat energy released by an organism is released into the <span>environment and unusable. This energy is also known as entropy which is defined as the tendency of things to be dispersed and spontaneous. This means that entropy is always random and becomes unavailable energy.</span>
<span>what volume of ammonia must you measure?
1.50 moles NH3 ( 22.4 L / 1 mole ) = 33.6 L NH3 should be measured
</span><span>how many molecules of nacl are in 23.40 grams nacl
23.40 g NaCl ( 1 mol / 58.44 g) (6.022 x 10^23 molecules / 1 mol ) = 2.4113 x 10^23 molecules
Hope these answer the questions. Have a nice day.</span>
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.
