Answer: option C - Carbon and Hydrogen have similar electronegativity values.
Explanation:
Carbon form COVALENT compounds with hydrogen. Examples are methane CH4, ethane C2H6, propane C3H8.
Electronegativity is the power to attract electrons. It is used to predict whether a bond will be covalent OR not. It can also be used to predict if the resulting molecule will be polar or nonpolar
Thus, Carbon with an electronegativity value of 2.55; and Hydrogen with 2.20 shows close similarities and THUS result in NONPOLAR and COVALENT BOND of Propane
Answer:
None of these cause the correct answer is 9/-5
When a stable atom gains or loses its electrons then that’s when it becomes the ion.
Explanation:
to calculate theoratical yield...first we must calculate how much Sucrose moles we have..in order to to do so...we must calculate molar mass of sucrose.
molar mass of sucrose is 342.3 g/mol.
now we can calculate how many sucrose moles we have by dividing the mass with molar mass of sucrose
735g/(342.3g/mol)=2.147mol
theoratically...according to stoichiometry..every 1 mole of sucrose yields 4 moles of ethanol...so...
2.147mole yield 2.147*4mol=8.588mol
now we must calculate weight of that much ethanol..molar mass of ethanol is 46.07 g/mol...
so we can multiple moles by molar mass to obtain the weight 8.588mol*46.07g/mol=395.649g
but we only obtained 310.5g...so percentage we have is
78.47%
if there is trouble with molar mases I used....use what you calculated...
If my explanation is good enough...please mark it as brainliest.thanks
An electric motor produces heat while running. The amount of heat is roughly equivalent to the amount of power delivered to the motor.
