Answer:
Mass of aluminium foil = 387.57_g
Explanation:
density of aluminium foil 2.70 g/cm³,
1_yd = 91.44_cm
1_in = 2.54_cm
Length of aluminum foil = 63.2_yd = 5779.008_cm
Width of aluminium foil = 11 in = 27.94_cm
Thickness of aluminium foil = 0.00035_in. = 0.000889_cm
Volume of aluminium foil = length × width × thickness = 5779.008_cm × 27.94_cm × 0.000889_cm = 143.54_cm^3
Mass of aluminium foil = (volume of aluminium foil) × (density of aluminium foil) = 143.54_cm³ × 2.70 g/cm³ = 387.57_g
Answer:
Check the attached one..I only draw the Dot method of Magnesium and Fluorine.. since i love chemistry ..Hope this helps you...Balance you have to do it yourself..If you didn't get the answer let me know in the comments..But you have try okay..
A negative ΔH and ΔS suggests that the reaction is exothermic and the leads to a decrease in the entropy of the system. In this case, the spontaneity of the reaction depends on the temperature and reaction is spontaneous at low temperature and non-spontaneous at a high temperature.
