F. Lectura. Read the passage about Álvaro and answer the questions in complete Spanish statements. ¡    ¿    ñ    á    é    í    ó    ú    Á    É    Í    Ó    Ú    Ñ   Mi nombre es Álvaro Martínez y soy de Miami, Florida. Soy bilingüe: hablo inglés y español. Mi familia es de origen hispano. Mi madre es de Puerto Rico y mi padre es de México.  Yo siempre hablo español en la casa con mi familia. Soy estudiante en la Universidad Internacional de Florida en Miami. Tomo clases de matemáticas, biología, y literatura los lunes y miércoles. También me gusta aprender idiomas y por eso tomo clases de  francés y portugués los martes y jueves. Ahora, puedo hablar un poco de portugués y francés. Vivo cerca de la universidad con mi familia. Hay residencias estudiantiles en la universidad pero no quiero vivir allí. No quiero tener un compañero de cuarto. Me gusta tener mi habitación privada y en mi casa no tengo que compartir el baño. La casa de mis padres es grande y cómoda. Además, a mi madre le gusta cocinar todos los días y yo prefiero comer en mi casa.             Los fines de semana cuando no estoy en la universidad, me gusta hacer muchas cosas.  Los viernes yo corro por la mañana y por la tarde leo mi correo electrónico. Por la noche mis amigos vienen a la casa y miramos televisión o jugamos Guitar Hero. Los sábados limpio mi dormitorio y ayudo a mamá en la casa. Por la noche salgo con mi novia a comer en un restaurante y a bailar. Los domingos estudio para mis clases y hago mi tarea. Tengo una semana bien ocupada.   5. ¿Qué hace Álvaro los viernes?

The major intermolecular forces between two water molecules are called ______________________.

The element hydrogen has the capacity to form ________.

Consider the following two molecules:(I) CCl4 and(II) HCl Which of the following is true about the polarity of these molecules? [Hint: Draw the Lewis dot structure and SNAP rule.]

Note: Use the Smaller Amount of Product (SAP) approach for this problem. All remaining conversion steps begin with the SAP amount.Octane (C8H18, MM = 114.23 g/mol) is a component of gasoline. Combustion of octane is represented by the following balanced chemical equation2 C8H18(l) + 25 O2(g) → 16 CO2(g) + 18 H2O(g)If a reaction mixture contains 218 g C8H18 and 455 g O2, (a) Identify the limiting reactant and excess reactant based on the SAP math. [4 points](b) How many grams of CO2 are expected to form? [1 point](c) How many moles of H2O are expected to form? [2 points](d) How many grams of excess reactant are consumed in the reaction? [2 points](e) How many grams of excess reactant are left over once the reaction is complete? [1 point]Enter the following in the text box provided and show your full work on scratch paper.(a) Limiting reactant = _____________ (type the chemical formula) and excess reactant = _____________ (type the chemical formula).(b) Mass of CO2 = ______________ g CO2. Enter the value in the text box.(c) Moles of H2O expected to form = ______________ mol H2O. Enter the value in the text box.(d) Mass of excess reagent consumed in the reaction = ______________ g. Enter the value in the text box.(e) Mass of excess reagent left over after the reaction is complete = ______________ g. Enter the value in the text box.

Consider a redox reaction: Mg + Cu2+ → Mg2+ + Cu. Which of the following is/are true? Select all that apply.(Hint: OIL RIG)(A) Mg is reduced.(B) Cu2+ is reduced.(C) Mg is oxidized.(D) Mg is oxidized.

The balanced equation for the combination reaction of hydrogen gas and solid iodine is: H2(g) + I2(s) + 52 kJ → 2 HI(g) Is this reaction is exothermic or endothermic? [BLANK-1]. The enthalpy change (∆H) value for this reaction should be indicated with positive or negative sign. [BLANK-2].

What coefficient is placed in front of O2 to complete the balancing of the following equation?  CH4(l) + ? O2(g) → CO2(g) + 2 H2O(g)
