A reaction has a rate law of Rate = (1.25 M⁻²s⁻¹)². What concentration of would give the reaction a rate of 0.0891 M/s if the concentration of is 0.250 M?

The radioisotope ¹⁴C (half life = 5730 years) is used for carbon dating. What is the first order rate constant for ¹⁴C?

What amount of time is required for the concentration of A to decrease from 0.800 M to 0.200 M in the zero-order reaction A → B? (k = 0.0567 M*s⁻¹)

What is the order of the reaction A → B given the plot shown?

How many mL of 0.235M of NaOH(aq) is required to titrate (completely neutralize) 35.0 mL of 0.125M H3PO4(aq)?                        3 NaOH (aq)  +    H3PO4 (aq)  →    Na3PO4  (aq)   +  3 H2O  (l)     Mark your answer next to words “Final answer is”.

Consider BrF3 molecule.  1) Use your own words, describe how chemical bonds are formed in Valence Bond Theory between Br and F atoms? 2) What’s the molecular geometry of the molecule (molecular geometry only)? Explain how you get your conclusion. Mark your answer next to words “Final answer is”.

Match the word learning principles/theory with the example.

At the end of the screening, the parent says “Can I get these EVALUATION results to show my husband?” You explain that today was a SCREENING not an evaluation.  You use the following facts to support your discussion.  “A screening_____” (select all that apply).  ***NOTE:  The question is worth three points but that does not mean there are three correct answers.

At six months old, Noah’s parents should see the emergence and coordination of joint attention.  The clinician discusses joint attention with you and expects you to know the following terms for any upcoming screenings on 6-12 month old children.  Match the example with the key term.

Noah is likely able to pay attention to the prosodic and phonetic regularities of speech as seen in detecting rhythm and combinations of specific sounds.  This skill is called:
