Draw all resonance structures for the nitric seld molecule, HNO, (NO₂OH) Explicitly drew all atoms. Inchade all valence lone pairs sis your answer Do not include overall ion charges or formal charges in your drawing. Do not draw double bonds to oxygen unless they are needed for the central atom to obey the octet rule. […]

Moment generating function for binomial distribution Let X have the binomial distribution with probability distribution Show that (a) M(t) = ( 1 − p + pet ) n for all t (b) E(X) = np and Var(X) = np ( 1 − p ) The Correct Answer and Explanation is : Let ( X )

Specify the action of the muscle that is highlighted in the image. Retraction of the scapula Abduction of the arm Flexion of the arm Depression of the scapula Extension of the arm Lateral rotation of the arm The Correct Answer and Explanation is : The muscle highlighted in the image is the trapezius, a large,

Use the body temperatures, in degrees Fahrenheit, listed in the accompanying table. The range of the data is 3.3°F. Use the range rule of thumb to estimate the value of the standard deviation. Compare the result to the actual standard deviation of the data rounded to two decimal places, 0.69°F, assuming the goal is to

Continuing review of an approved and ongoing study posing more than minimal risk that was initially approved by a convened IRB: Must be conducted by a convened IRB. Is limited to review of unanticipated problems. Must occur within 12 months of the approval date. Is not required unless additional risks have been identified. The Correct

This is an IR spectrum of a sample of methyl cinnamate. In what way do you expect the IR of the product (methyl cinnamate) to be different than the methanol and cinnamic acid that was started with? Based of the IR shown, Is there ar OH stretch? Is there a C=0 stretch? Where should the

carbon has an atomic number of 6. how many protons does carbon atom have? The Correct Answer and Explanation is : The atomic number of carbon is 6, which means a carbon atom has 6 protons. Explanation: The atomic number is a fundamental property of an element. It represents the number of protons in the

and molecular geometry around the two C atoms? What is the hybridization of each of the C atoms? What orbitals overlap to form the σ and π bonds between carbon and oxygen? The Correct Answer and Explanation is : 5. Carbonyl Fluoride (COF₂) Lewis Structure Geometry and Hybridization 6. Acetamide (CH₃CONH₂) Lewis Structure Geometry and

1) Coulomb’s law is F = (kq_{1}q_{2}) / (r ^ 2) where k = 9 * 10 ^ 9 in Sl units. Suppose that q * 1 = 6mu*C and q * 2 = 4mu*C and r = 25 cm, calc. the force between these particles. 2) The proton and electron in a H atom

calculate the length and width of each in μm. (If the cell is round, measure its diameter. If there is more than one cell present, measure the cell indicated by the arrow. Again, it may be easier to measure with a piece of paper and then compare to the micrometer below). Note: we do not
