The following properties are observed for an unknown element. Identify the element from its properties. (a) The neutral atom has two unpaired electrons. (b) One of the valence electrons in the ground-state atom has ml = +1. (c) The most common oxidation state is +4. (d) If an electron in a hydrogen atom were excited to the same principal quantum level, n, as the valence electrons in an atom of this element, and fell to the n - 1 quantum...
Carry out analysis of a beam hanging under its own weight in a
1d space using the finite element 10-step procedure. Carry out the
analysis using a single 1d quadratic element. The figure below
contains the properties for the beam.
The properties of the beam are its length L123 mm, its cross-sectional area, A 0.0456 m2 its elastic modulus E205 -109 Pa and its density: p 765.2 kg m-3 constant body load: b
The properties of the beam are its...
(1x5) marks Iron is an important element, which our body needs for many of its functions. In our blood, it is the carrier of Oxygen. It is the fourth most common element in the earth's crust. In today's world, iron and its alloys are the most common industrial material due to its low cost and better mechanical properties. The extraction of iron metal takes place from its ore in a number of steps, which are summarized below. Iron ore, coke...
Hello, thank you very much in advance for answering my question! Commonwealth Construction (CC) needs $3 million of assets to get started, and it expects to have a basic earning power ratio of 20%. CC will own no securities, so all of its income will be operating income. If it so chooses, CC can finance up to 40% of its assets with debt, which will have an 8% interest rate. If it chooses to use debt, the firm will finance...
Part I: Periodic Trends of the Elements Using only the Periodic Table, make predictions about properties such as atomic size and to determine electron configurations for atoms and fons. For this section, consider these six elements: OF P Ar K Mg Description Circle ALL that apply, or "None of these" Support your answers. 1. Its atomic radius is larger than a sulfur atom. OF Mg P Ar K None of these 2. Its most stable ion: (a) has the same...

True/False 5) Where are protons, neutrons and electrons located? 6) Can you determine the atomic number and mass number from...
2. (3 points) In lab, you will form complexes using different ligands. Use your lab manual to identify and draw the structural formula (lewis formula) for the following: a. A charged monodentate ligand (answer cannot be a halide ion) b. A polydentate ligand c. The CO ligand, not used in the laboratory. Is it likely CO can form a coordinate covalent bond from more than one atom? Explain. NC CN Ni Geometry of Coordination Compounds A compounds geometry (i.e., how...
Question 3-10 points One of the most important functions of the membrane in living cells is its ability to selectively pass either sodium ions (Na) or potassium ions (K) through channels in the membrane. These ions have the same charge +le). The electric force exerted on them by the membrane will be similar. In addition, they are about the same size (RNa~0.12 nm, RK 0.15 nm). So how can channels in the membrane distinguish between them? One mechanism that has...
