Answer:
Mass of carbon = 236.5 g
Explanation:
Given data:
Mass of C₃H₆ = 275 g
Mass of C = ?
Solution:
Formula:
Mass of carbon = molar mass of carbon/ molar mass of compound × mass of compound
Molar mass of carbon = 12 g/mol
Molar mass of compound = 42 g/mol
Mass of carbon = 36 g/mol / 42 g/mol × 275 g
Mass of carbon = 0.86 × 275 g
Mass of carbon = 236.5 g
Answer:
.........................................
Explanation:
Answer:
1. sublimation
2.melting
3.melting
4.sublimation
Explanation:
melting is a process when solid changes to liquid
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
Between 1858 and 1920, Mars was thought by many, including some scientists, to be very similar to Earth, only drier with a thick atmosphere, similar axial tilt, orbit and seasons as well as a Martian civilization that had built great Martian canals.
Answer:
Student's percent yield = 94.6%
Explanation:
Given:
Estimated yield of BaSO₄(s) = 1.352 grams
Actual yield = 1.279 grams
Find:
Student's percent yield = ?
Computation:
Student's percent yield = [Actual yield / Estimated yield of BaSO₄(s)]100
Student's percent yield = ( 1.279 grams / 1.352 grams)100
Student's percent yield = (0.946)100
Student's percent yield = 94.6%
