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.
G We've all blown up balloons. When you blow into a balloon, you are putting in more moles of gas. Let's say that on the second exhalation (blow) you blow in the exact same number of moles as you did with the first exhalation. So, you doubled the number of moles in the balloon. If the temperature and pressure remained constant, what is true about the volume of the gas in the balloon
The answer is B atmosphere (clouds )
Answer:
The largest temperature change corresponds to the metal with the lowest specific heat
Explanation:
The metals listed in problem 2 are missing, so I will answer this question in general terms.
The formula that relate the heat absorbed or rejected from a body (q), the mass of the body (m), its specific heat (cp), and the temperature change (ΔT) is:
q = m*cp*ΔT
Given that all materials receive the same amount of heat and have the same mass then we can rewrite the formula as follows:
q/m= cp*ΔT = k
where k is some constant (the same for the 5 cases). Therefore, the greater the cp, the lower the ΔT, and viceversa.
