H2O(l). The reaction released heat and is said to be exothermic. HCl is the limiting reactant of the reaction and o.oo5 moles of it was used. The heat generated by the reaction is 55.8 kJ. The sign of T of the reaction used for calibration is opposite to that of H. In the determination of heats of reaction‚ the reaction of 15 mL 1 M CuSO4 + 0.05 g Zn produced a net ionic equation of CuSO4 + Zn ZnSO4 + Cu. The limiting reactant of the reaction is Zn and 0.05 moles of it was used. The sign of T

Children vs. Dangerous Sports I’m sitting on the bleachers‚ watching my child play football‚ when suddenly another teammate jumps out and tackles my child to the ground causing a horrendous fracture to the leg. Later in the hospital‚ the doctor gives me some tragic news that I was dreading to hear; your child has two broken legs. Many brain issues and physical body injuries have had parents questioning themselves‚ ‘should I let my child engage in dangerous sports?’ First‚ when someone refers to

Grignard Reaction: Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent

demonstrably justified in a free and democratic society.” The government has to find reasonable ways to achieve or implement its legislation based on the concept of proportionality. Through establishing the reasonableness of the limitation‚ the objective of limiting the right to legal counsel during questioning seems to be overriding the constitutionally protected right. The limitation on the right to legal counsel during interrogation would be clearly unjustified since its purpose is inconsistent with the

repressing her emotions‚ yet her opinionated ways lead to her alienation. This makes her unreliable as the reader experiences the narrator’s life from her dysfunctional perspective. This makes it hard for the reader to connect to Esther‚ therefore limiting our empathy with her tragedy. In contrast‚ the reader sympathises with Leo as we see his youth and enthusiasm for life being destroyed‚ which enhances the tragedy. It could be said that Plath’s use of a simile to portray incongruity foreshadows

It limited naval power in order to prevent militarism. A way of limiting naval power was by limiting the ratio of ships that U.S. ‚ Britain‚ Japan‚ Italy‚ and France could have. This way the countries couldn’t increase their amount of ships just because they felt the need to compete with other countries that increased their amount

block will return to its original position when released because the net force up the plane exceeds the limiting friction down the plane. The downward displacement is being reduced gradually until a stage where the block stays stationary when released. At this point‚ the force up the plane equalized the limiting friction down the plane. If T is the tension of the spring‚ F is the limiting friction‚ and μ is the coefficient of static friction‚ then T- mg sin θ = F T- mg sin θ =
