Tickets to a movie cost $7.25 for adults and $5.50 for ... - Socratic 14 Nov 2016 · 4 adults and 2 students The objective is to have only one unknown in 1 equation. Let the count of adults be a Let the count of students be s Total ticket count = 6 So a+s=6" " =>" " a=6-s Total cost for adults =axx$7.25 Total cost for students = sxx$5.50 But a=6-s So total cost for adults =(6-s)xx$7.25 ~~~~~ We are told that the overall cost was $40 so [(6-s)xx$7.25] + …
How can I calculate the empirical formula of magnesium oxide? 19 May 2014 · You need to do an experiment to determine how much "Mg" and "O" are in a sample of the compound. > For example, you might heat a known mass of magnesium in a crucible and determine the mass of oxide formed. EXAMPLE Assume that you heated 0.297 g of magnesium and obtained 0.493 g of the oxide. What is the empirical formula of magnesium …
Chemistry; Calorimetry; Calculating Heat Capacity; Help Please? 8 Sep 2017 · If you take #T_"f"# #""^@"C"# to be the final temperature inside the calorimeter, you can say that the heat gained by the piece that starts at #45^@"C"# is equal to. #q_"gained" = m * c * (T_"f" - 45)^@"C"# Similarly, the heat lost by the piece that starts at #105^@"C"# will be equal to--keep in mind that this piece has twice the mass, or #2m#
How do you convert 45°C to Fahrenheit? - Socratic 2 Jun 2016 · Recall the formula to convert this. \mathbf(T_C = 5/9(T_F - 32)) Of course, T_C is the temperature in ""^@ "C", and T_F is the temperature in ""^@ "F".
A balloon has a volume of 2.50 L indoors at 22 degree C. If 23 Mar 2015 · A balloon has a volume of 2.50 L indoors at 22 degree C. If the balloon is taken outdoors on a cold day when the air temperature is -15 degree C (5 degree F), what will its volume be in liters? Assume constant air pressure within the balloon.
Leaving Groups - Organic Chemistry - Socratic F⁻ is a small ion. Its high charge density makes it relatively unpolarizable. The leaving group needs to be polarizable to lower the energy of the transition state. You should never see F⁻ leave in an #"S"_"N"2# reaction. Question: Why is water a good leaving group? Answer #color(white)(ll)#: It isn't! Hydronium ion is the leaving group ...
How can I calculate solubility of potassium nitrate? - Socratic 28 Jul 2014 · The only way to determine the solubility of potassium nitrate is to do an experiment or interpolate from a solubility graph. Solubility is the mass of a solute that can be dissolved in a given mass of solvent. Solubility varies according to temperature for the same solute and solvent. The solubility graph for potassium nitrate in water is shown below. EXAMPLE What is the …
Average Velocity - Calculus - Socratic The average velocity of a function f(x) over the interval from a to b is equal to the slope of the line connecting (a,f(a)) and (b,f(b)). Calculus Science
How many earth years are in 1 light year? - Socratic 29 Feb 2016 · An earth year is a unit of time. A light year is a measure of distance. A light year is the distance light will travel in a vacuum over the period of one (earth) year. Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300xx86400xx365 ~~ 5,875,000,000,000 miles.
Balancing Redox Equations Using the Oxidation Number Method Balancing a redox reaction requires identifying the oxidation numbers in the net ionic equation, breaking the equation into half reactions, adding the electrons, balancing the charges with the addition of hydrogen or hydroxide ions, and then completing the equation.
