4. Balance the equations using half-reaction method (in basic solution) I. Assign an oxidation number for each atom in a skeleton equation (reactants, products) N2H4(aq) + Ag2O(s) \rightarrow N2(g) + Ag(s) II. Separate the redox equation into two half-equations Balance the number of atoms in each half-equation. O and H balance last. Balance each half-equation for electric charge by adding electrons. Multiply each half-equation by appropriate number to adjust the coefficients: the same number of electrons appears in each half-equation. (Use least common multiple approach). Add the two adjusted half-equations to obtain an overall redox equation. III. Simplify the overall equation if it necessary/adjust to basic solution. IV. Assessment:

1. Given the acceleration time graph (on the board). Construct the position time graph and velocity time graph 2. Given the position as a function of time. Calculate the velocity and acceleration at 5 seconds. $x(t) = e^{t^2} + 4t$ 3. A balloon is moving upward at a constant velocity of 5m/s. A stone was released by the passenger of the balloon while the balloon is 25 m above the ground. A car that is moving with a constant velocity of 2m/s was hit by the balloon upon impact. If the cars' height is 1m, what is the distance of the car when the stone was released?

In the lectures we mentioned that a candidate for dark energy is a scalar field named quintessence. This field is dynamically evolving in time and its energy density is given by (as in the case of the inflaton scalar field) $\rho = \frac{1}{2}\dot{\phi}^2 + V(\phi)$, while its pressure is given by $P = \frac{1}{2}\dot{\phi}^2 - V(\phi)$, where $\dot{\phi} = d\phi/dt$ and $V(\phi)$ is a potential (we are working in $c = 1$ units). Derive the expression for the equation of state parameter $w = \frac{P}{\rho}$. Assuming that $V(\phi) = V_0$, where $V_0$ is a positive constant, derive the condition for $w \approx -1$. Comment on the similarity of this case with the cosmological constant.
