At 25°C, the equilibrium constant Kc = 0.0012 for the reaction  B(aq) + C(aq)  ↔  2A(aq)     A solution of 0.80 M of B and 0.80 M of C is mixed and allowed to come to equilibrium. A student does the following steps below to calculate the equilibrium concentration of A.  There is one error in this calculation. Identify the step where the student made an error.  (keeping extra digits until the end of the calculation is not an error).

Jorgito: ¡Ay, Macarena! ¡Creo que hay [q14] debajo de mi cama! Macarena: Tranquilo, Jorgito. ¿Ves? No hay [q15] allí. ¡Tienes una gran imaginación! Jorgito: Macarena, no quiero ir a dormir porque [q16] estoy cansado [q17] me leíste el libro que me gusta. Macarena: Es verdad, Jorgito. ¿Prefieres leer un libro de aventuras [q18] de animales?

GRAMMAR (16 pts) GRAMMAR A. Taking care of ourselves (Reflexive Verbs) (8 pts) Paso 1 (4 pts)Tomás is talking about himself, his friends and family, and their health. Complete what he says with the correct forms based on the context.

A beam has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 7 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

A beam has dimensions of b = 14 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 5,500 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

How many taxonomic categories did Linneaus develop? In the “easy method” that I give for learning the categories (the mnemonic device), what is the alternate name for “Kingdom” (starts with “K”)?

If there is compressive reinforcement in a beam, you must assume in your calculations that this steel will yield.

For economic reasons, reinforced concrete should be designed to be _______.

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 6,400 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.
