3. (1 pts.) For steady-state system shown in the figure, where a jet of liquid striking a curved vane, which turns the jet 90°. Assuming no friction between the jet and the surface, determine the reaction force of the spring? $$P_{atm} = 101 kPa$$ $$A = 0.10 m^2$$ $$V = 17 m/s$$ $$\rho = 850 kg/m^3$$ 4. (1 Pts.) A pump is being used to deliver 130 L/min of hot water from a tank through 15 meters of 2.5-cm diameter, smooth pipe, exiting through a 1.0 cm diameter nozzle 3 meters above the level of the tank as shown in the figure. The head loss from friction of the pipe is 8.33 m. The specific weight of the hot water is 9.53 $$kN/m^3$$. Calculate the head delivered to the water by the pump.

Complexes (A) and (B) have the chemical formula [NiCl$_2$(PPH$_3$)$_2$]. (A) is diamagnetic and a d-d transition is observed at wavelength, $\lambda$ = 500 nm. On heating, (A) can be converted to the paramagnetic isomer (B), this exhibits a d-d transition at $\lambda$ = 650 nm. (i) Draw structures for the three possible isomers of [NiCl$_2$(PPH$_3$)$_2$]. (ii) Deduce, with reasoning, the two isomers in part (a)(i) which correspond to (A) and (B). Use d-orbital splitting diagrams and steric considerations in the answer and include an explanation of the magnetic and spectroscopic properties of the complexes.

We naturally dislike when someone looks at us with disgust or disdain, even a stranger. This is because mirror neurons allow us to see the opposite of how others perceive us, and most humans are uncomfortable with positive perceptions from strangers. their negative perception of us, even if their view may not fully reflect the reality of our selves, threatens to become part of our self-image. the looking-glass self allows us to see the reality of our negative traits as others do, and such reality hurts our self-concept. humans feel the need to be liked by all members of their community, including those who are not part of one's social group.

2. A student doing this experiment to find the mass % Ca$^{2+}$ in a tablet was careless and did not dry the sample to a constant mass. What would be the effect of this mistake on the final mass % Ca$^{2+}$ obtained in the experiment? Circle the effect from the list and then explain completely why you have given that answer. Be sure to explain what measurements change and in what direction with your explanation here. Increase, Decrease, Stay the same, Increase OR decrease, 3. How much of each of these reagents do you need for the entire experiment? Watch sig figs! 2.0 M HCl (aq)____ ml total. 1.0 M Na$_2$CO$_3$ (aq)____ ml total. 4. What does the word \"decant\" mean in this module? 5. What is the mass % Ca$^{2+}$ in CaCO$_3$? [HINT: review \"percentage composition\" in Section 3.3 of your Chem 112 textbook and this chapter of the Chem 112L lab manual.]
