Sorry I don’t know but o have to answer for pionts
Answer:
See figure 1.
Explanation:
In this case have to take into account that <u>all structures</u> must have the formula: . If we remember the <u>general formula for alkanes</u>: if we have <u>"7" carbons (n=7)</u> we will have <u>16 hydrogens</u>. Therefore all the structures that fit with this formula are alkanes.
Answer:
Theanswer to your question is:
Limiting reactant = FeCl₃
Excess reactant = 1.66 g of Mg
Explanation:
Data
Mg = 41 g = 24.31 g/mol
FeCl₃ = 175 g = 162.2 g/mol
3Mg(s) + 2FeCl₃(s) → 3MgCl₂(s) + 2Fe(s)
3(24.31) of Mg ------------------ 2(162.2) of FeCl₃
72.93 g of Mg ------------------ 324.4 g of FeCl₃
Theoretical Proportion = 324.4/72.93 = 4.44
Practical proportion = 175 / 41 = 4.2
As the proportion disminishes the limiting reactant is FeCl₃.
Excess reactant
72.93 g of Mg ------------------ 324.4 g of FeCl₃
x ------------------------- 175 g of FeCl₃
x = (175 x 72.93) / 324.4
x = 39.34 g of Mg
Excess = 41 - 39.34
= 1.66 g of Mg
Any positive number of Celsius is going to be above freezing. 0°C is the freezing point of water. 100°C is the boiling point of water. So 214°C is going to be extremely hot, as it is well above 400°F which is around the temperature many ovens use to cook food.
As for Neptune, what I could find out is the the surface is around negative 200°C which is extremely cold.
