Explanation:
the structural formula of butyl pentyl ether
Answer:
Because sodium is on the left side of the PT and phosporus is on the right side. And atomis radius decreases from left to right.
Explanation:
First you need to find the balanced chemical formula.
CuCl₂+2NaNO₃→2NaCl+Cu(NO₃)₂
Then you can find out how much NaCl 31.0g of CuCl₂ should produce using stoichiometry. Divide 31.0g by the molar mass of CuCl₂ (134.446g/mol) to get 0.2306mol CuCl₂. Than multiply 0.2306mol CuCl₂ by 2 to get 0.4612mol NaCl. Than multiply 0.4612mol by the molar mass of NaCl (58.45g/mol) to get 26.95g of NaCl.
that means that 100% yield would give you 26.95g of NaCl so to find percent yield divide 21.2 by 26.95 to get 0.7867 which is 78.7% yield
Therefore the answer is 78.7% yield.
I hope this helps. Let me know if anything is unclear
Answer:
0.350 g of iron
Explanation:
Step 1: Given data
Mass of iron (m): 350 mg
Step 2: Convert the mass of iron to milligrams
In order to convert the mass of iron from grams to milligrams we need a conversion factor. In this case, the conversion factor is 1 g = 1,000 mg.
350 mg Fe × 1 g Fe/1,000 mg Fe = 0.350 g Fe
350 milligrams of iron is equal to 0.350 grams of iron. We conserve the 3 significante figures of the original data.
