For many purposes we can treat butane (C₁H₁0) as an ideal gas at temperatures above its boiling point of — 1. °C. - Is it possible to change the temperature of the butane at the same time such that the volume of the gas doesn't change? If you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C. Explanation Check yes O no X °C + x10 X 2

In the first step, aluminum hydroxide reacts to form alumina and water: 2 Al(OH)3(s)-Al₂O3(s) + 3 H₂O(g) 11 In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2 AL₂O3(s)+3 C(s)-4 Al(s) + 3 CO₂(9) Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon.

The two must be done independently of each other, as they are completely unlike. A qualitative analysis must always be done before a quantitative analysis. A quantitative analysis must always be done before a qualitative analysis. A qualitative analysis identifies the type of ion in solution and the quantitative analysis will determine how much of this ion is present. A quantitative analysis identifies the type of ion in solution and the qualitative analysis will determine how much of this ion is present. i 11:15

Calculate the expected distribution of asteroid dust over the surface of the Earth in grams per cubic centimeter(g/cm2). Note: The your answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm^2. %3D Note: Your answer is assumed to be reduced to the highest power possible.

Q27 A 10-1 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is plated on solid media, and 265 colonies of bacteria grow on the plate.  Assuming each colony came from a single bacterium, how many bacteria are in a single mL of the original culture? Express your answer as a whole number. Since only 0.1 mL is put on the plate, this counts as an extra dilution!!! Any time less than 1 mL is transfered, a dilution is being performed. Any time more than 1 mL is transfered, a concentration is being performed.
