Answer:
Ti
Explanation:
Ti is titanium and does not share any similar properties with the likes of Si, silicon and At, astatine.
- Titanium is a transition metal and a solid.
- Silicon and Astatine are non - metals.
- Silicon and Astatine also belongs to the p-block on the periodic table whereas Titanium is found on the d-block.
- Silicon and Astatine would prefer to take part in reactions where they can gain electrons because they are non metals whereas Titanium due to its metallic property would prefer a reaction where it can lose electrons.
Answer:I would have to say d because isn’t that what they make phones out of and it has to be safe right ?
Explanation:
Answer:
<u>49.54 g</u>
Explanation:
Let's take the masses of both calcium sulfate and sulfur dioxide formed.
Sulfur dioxide = 32 + 2(16) = <u>64 g</u>
Calcium sulfate = 40 + 32 + 4(16) = <u>136 g</u>
So, under ideal conditions, to produce 136 g of Calcium sulfate, we require 64 g of Sulfur dioxide.
But, it mentions the process is only 95% efficient.
Hence, taking the ratio :
x = <u>49.54 g</u> (approximately)
