Answer:

Lab reports are written to describe and analyse a laboratory experiment that explores a scientific concept. They are typically assigned to enable you to: Conduct scientific research. Formulate a hypothesis/hypotheses about a particular stimulus, event, and/or behaviour.

I Suggest going back in the book to look through what you want to use for your presentation as well as your key details and purpose for writing.

A 1.25-g sample contains some of the very reactive compound Al(C6H5)3. On treating the compound with aqueous HCl, 0.951 g of C6H
Oksanka [162]
<span>83.9% First, determine the molar masses of Al(C6H5)3 and C6H6. Start by looking up the atomic weights of the involved elements. Atomic weight aluminum = 26.981539 Atomic weight carbon = 12.0107 Atomic weight hydrogen = 1.00794 Molar mass Al(C6H5)3 = 26.981539 + 18 * 12.0107 + 15 * 1.00794 = 258.293239 g/mol Molar mass C6H6 = 6 * 12.0107 + 6 * 1.00794 = 78.11184 g/mol Now determine how many moles of C6H6 was produced Moles C6H6 = 0.951 g / 78.11184 g/mol = 0.012174851 mol Looking at the balanced equation, it indicates that 1 mole of Al(C6H5)3 is required for every 3 moles of C6H6 produced. So given the number of moles of C6H6 you have, determine the number of moles of Al(C6H5)3 that was required. 0.012174851 mol / 3 = 0.004058284 mol Then multiply by the molar mass to get the number of grams that was originally present. 0.004058284 mol * 258.293239 g/mol = 1.048227218 g Finally, the weight percent is simply the mass of the reactant divided by the total mass of the sample. So 1.048227218 g / 1.25 g = 0.838581775 = 83.8581775% And of course, round to 3 significant digits, giving 83.9%</span>

What is the length of the hypotenuse of the right triangle ABC in the figure?
Lostsunrise [7]
Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse. 
The triangles are similar (right triangles which share an angle (A), so... 
AD/AC = AC/AB 5/6 = 6/AB AB = 6*6/5 = 36/5 = 7.2
