What is shape of the molecule in which the central atom is bonded to three other atoms and has one lone pair of electrons on the central atom?

When concentration of hydronium ions (H3O+) in solution is [1] than concentration of hydroxide ions (OH-), solution is [2].

Molecule has [1] electron geometry, and has [2] molecular geometry (shape), when central atom is bonded to [3] atoms and has one lone pair of electrons on central atom.

Suppose you have a data set with the following five number summary: Minimum = 26              Q1 = 32              Median = 34              Q3 = 38              Maximum = 58 What is the lower cutoff point for outliers using the IQR criteria?

How many milliliters of 2.60 M sulfuric acid are needed to neutralize 55 mL of 3.00 M sodium hydroxide?

Problem 1 (8 points) Danny’s Distribution Company purchased factory equipment with an invoice price of $78,000. Other costs incurred were freight costs, $1,300; installation wiring and foundation, $2,200; material and labor costs in testing equipment, $700; oil lubricants and supplies to be used with equipment, $500; fire insurance policy covering equipment, $1,500. The equipment is estimated to have a $5,000 salvage value at the end of its 8-year useful service life. Instructions Compute the acquisition cost of the equipment. Clearly identify each element of cost (i.e. show your work). If the straight-line method of depreciation was used, the annual rate applied to the depreciable cost would be __________.
