2. Your chemistry lab partner is interested in studying how industrial chemicals can pollute the environment. What field of specialization would you recommend to your lab partner and which courses should they take in order to study it? Explain your answer. (4 points)

Bodies of water tend to moderate climate because __ water is always cooler than the nearby landmasses the hydrogen bonding in water causes it to be cohesive All of the listed responses are correct. water has a high heat of vaporization the hydrogen bonding in water gives it a high specific heat IDON'T KNOWYET

Calculate the value of $E^{\circ }$ and $\Delta G^{\circ }$ for the following reaction. $2Fe^{2+}(aq)+Br_{2}(aq)\rightleftharpoons 2Fe^{3+}(aq)+2Br^{-}(aq)$ $K=4.85\times 10^{10}$

Valence bond theory describes covalent bonds as the overlap of half-filled orbitals with electron pairs localized between two bonded atoms uses a combination of atomic orbitals to create molecular orbitals with electrons delocalized throughout the entire molecule creates bonding and anti -bonding interactions based on which orbitals are filled correctly predicts paramagnetism in molecules

Question 22 (8 points) Match each orbital type with the maximum number of orbitals possible: $\square $ porbital $\square $ d orbital $\square $ forbital $\square $ s orbital 1. 1 2. 3 3. 7 4. 5 5. 9

The reaction of 0 .194 g of Zn with HCl(aq) gave 80.3 mL (at $23.4^{\circ }C$ of hydrogen gas collected over water in a gas tube. The water was 18.5 mm higher in the gas tube than it was in the beaker. The barometer reading is 698. mm Hg. Following the steps on pages 1 to 3, complete this table of data. Volume of $H_{2}$ Gas Generated (mL) $\square $

What is the term for the product that results from hydrocarbons that react with other chemicals and sunlight? gaseous emissions photochemical smog carbon monoxide particulate matter

Predict the sign of $\Delta S$ for the following process. $2NO(g)+O_{2}(g)\rightarrow 2NO_{2}(g)$ A. $\lt 0$ B. $\gt 0$ C. $=0$

Calculate the $\Delta H$ for the reaction $NO_{(g)}+O_{(g)}\rightarrow NO_{2(g)}$ Given the following information:Eq $1:NO_{(g)}+O_{3(g)}\rightarrow NO_{2(g)}+O_{2(g)}$ $\Delta H=-198.9kJ/mol$ Eq 2: $O_{3(g)}\rightarrow 3/2O_{2(g)}$ $\Delta H=-142.3kJ/mol$ Eq 3: $O_{2(g)}\rightarrow 2O_{(g)}$ $\Delta H=495.0kJ/mol$

Classify the following chemicals by type of particle: carbon ion non metal atom formula unit molecule

Match each process with whether it is endothermic or exothermic: $\square $ A candle flame 2 $\square $ The freezing of water $\square $ v The combustion of butane $\square $ v Photosynthesis $\square $ pack used for injuries The chemical reaction in a cold $\square $ The vaporization of rubbing alcohol 1. Endothermic 2. Exothermic
