1inch= 0.0254 meter
0.0254 x15=0.381
Removing chloride ion is the reaction away
The reaction is that,
1 mole is SiCL4 will produce 1 mole of Si(s) Since there is 1 to 1 relationship then we just multiply the enthalpy of reaction by the number of moles
Enthalpy = -625.5 kJ/mole × 12.5 Moles
= -7,818.75 KJ
= -0.78 ×10⁴KJ
Answer: A heterogeneous mixture is a mixture in which its components retain their identity.
Why: Heterogeneous mixtures have several parts which can't be separated, like an italian dressing. Therefore, it's prefix is (hetero), which means something along the lines of "different". In a homogeneous mixture, it can be separated, and the prefix (homo) means "same".
Answer:
20.9%
Explanation:
- The percentage by mass of solution is given by dividing the mass of solute in grams by the mass of solution in grams then multiplying it by 100%.
% Mass of solution = mass of solute/mass of solution × 100%
= (27.0 g/ 129.0 g) × 100%
= 20.93%
= 20.9%
