Answer:
Hi
2-methyl-1-propanetiol is found in alcoholic beverages. It is a food additive, and is also found in guava, milk, cooked beef, cooked pork and beer. It is also used as a flavoring. A dose of 7168 mg / kg produces muscle weakness, ataxia, cyanosis. An intraperitoneal dose of 917 mg / kg can cause nervousness and a feeling of spastic paralysis. In the attached file is the scheme.
Explanation:
Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.
Good luck ;)
<h3><u>Answer;</u></h3>
321.8 g CaF2
321.5 g Al2(CO3)3
<h3><u>Explanation;</u></h3>
The equation for the reaction is;
3 CaCO3 + 2 AlF3 → 3 CaF2 + Al2(CO3)3
Number of moles of CaCO3 will be;
=(412.5 g CaCO3) / (100.0875 g CaCO3/mol)
= 4.12139 mol CaCO3
Number of moles of AlF3 will be;
= (521.9 g AlF3) / ( 83.9767 g AlF3/mol)
= 6.21482 mol AlF3
But;
4.12139 moles of CaCO3 would react completely with 4.12139 x (2/3) = 2.74759 moles of AlF3.
Thus; there is more AlF3 present than that, so AlF3 is in excess, and CaCO3 is the limiting reactant.
Therefore;
Mass of CaF2 will be;
(4.12139 mol CaCO3) x (3/3) x (78.0752 g CaF2/mol) = 321.8 g CaF2
Mass of Al2(CO3)3 on the other hand will be;
(4.12139 mol CaCO3) x (1/3) x (233.9903 g Al2(CO3)3/mol) = 321.5 g Al2(CO3)3
Answer:
durage
Explanation:
durage just doesn't make sense compared to the other 3
The answer would be triple point! Easy to remember because triple as in 3 :)
