Ingvar Kamprad and IKEA 1. What do you think was the main reasons for IKEA’s success in Sweden and other Scandinav countries in the period up to 1973? To begin with we have to resituate the context; we are now in the post war boom era when a lot of industries on both sides‚ even in Germany‚ developed substantially and very rapidly. We are now in a wealthier and reborn Europe. As a result new needs started to appear; back in those days‚ it was for example customary to hand down custom-made furniture

A bus topology is the minimum complex network configuration it creates use of a single transmission medium called a coaxial cable. The star topology consists of shielded twisted pair wire (STP) or unshielded twisted pair wires (UTP). Due to the high cost of STP wire‚ most networks use UTP‚ however‚ STP wire must be used if the distance between the hub and the node beat 110m. In most examples the cable is many different lengths joined by a T-connector which allows the cable to divide into various

moles-stoichiometry-practice-problems Now you’re ready to use what you know about conversion factors to solve some stoichiometric problems in chemistry. Almost all stoichiometric problems can be solved in just four simple steps: 1.Balance the equation. 2.Convert units of a given substance to moles. 3.Using the mole ratio‚ calculate the moles of substance yielded by the reaction. 4.Convert moles of wanted substance to desired units. These "simple" steps probably look complicated at first

Introduction The objective of this experiment is to combine Magnesium (Mg) with hydrochloric acid (HCl) to determine the molar volume of hydrogen gas (H2) (converted to the molar volume at STP) and then‚ to compare obtained results with the molar volume of an ideal gas. To determine the measured molar volume of hydrogen gas‚ we are going to use this equation: The molar volume of the ideal gas will be determined by the equation ‚ where T = 237 K‚ P = 101.3 kPa. The hydrogen gas will be collected
