Aqueous hydrobromic acid (HBr) will react with solid sodium hydroxide (NaH) to produce aqueous sodium bromide (NaBr) and liquid water (H, 0).
Suppose 75.2 g of hydrobromic acid is mixed with 14. g of sodium hydroxide. Calculate the maximum mass of sodium bromide that could be produced by the
chemical reaction. Be sure your answer has the correct number of significant digits.
Gaseous butane (CHa (CH,), CHg) will react with gaseous oxygen (0.) to produce gaseous carbon dioxide (CO,) and gaseous water (H, O). Suppose 4.1 g
of butane is mixed with 19.7 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the
correct number of significant digits.
A subwoofer needs a household voltage of 110A to push a current of 5.5A through its coil. What is the resistance of the subwoofer?
An electric heater works by passing a current of 100A through a coiled metal wire, making it red hot. If the resistance of the wire is 1.1 ohms, what voltage must be applied to it?
A light bulb has a resistance of 5 ohms and a maximum current of 10A.How much voltage can be applied before the bulb will break?

3.) Lim [f(x) +g(x)]
x->c
In a study of inter spousal aggression and its possible effect on child behavior, the Behavior Problem Checklist (BPC) scores were recorded for 47 children and whose parents were classified as aggressive. The sample mean and standard deviation were 7.92 and 3.45, respectively. For a sample of 38 children whose parents were classified as non-aggressive, the mean and standard deviation of the BPC scores were 5.80 and 2.87, respectively. Do these observations substantiate the conjecture that the children of aggressive families have higher mean BPC than those of non- aggressive families? Use a significance level of 0.05.
Consider last month you started a new business of Electronics items. You are also thinking to start different branches of your business in your city as well as outside. To increase the revenue, you may explore the international market. In the dynamic market, you would face tough competition from different online as well as offline players during the journey.
