Please comment on The mineralogy, chemistry and origin of alkaline igneous rocks with illustrated examples.(Unlimited words)
A chemical property of a substance can be observed without changing its composition or interacting with another substance. -A physical property can be observed without a chemical reaction.
The reaction of 0.25 g magnesium with 100 mL of 1 M hydrochloric acid (density d = 1.02 g/ml) raises the temperature of the solution from 20 °C to 35 °C . The specific heat for HCl is 3.93 J/(g.C).
Consider the following Balanced equation: SiO2+3C--->SiC+2CO: Complete the following table, showing the appropriate number of moles of reactant and products
A 12-liter tank contains helium gas pressurized to 160. What size tank would be needed to contain this same amount of helium at atmospheric pressure 1 ATM.
A Power plant is the main point source of SO2 emissions for a 25 km2 area. Estimate the steady-state concentration of SO2 for this area from this point source given the following temperature data. Windspeed= 5km/hr.
Using the periodic table, arrange the atoms in each of the following sets in order of increasing electronegativity: a) CL, F, Br; b) B, O, N; c) Mg, F, S
Which of the following tests could differentiate between pentanal and 3-pentanone, also what would occur.
Bulb B has 0.4 mole of ideal gas B at a pressure of 3 atm and is at 100 C. Calculate the final pressure of gas A when the two bulbs are open to each other.
There is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of Magnesium metal consumed in the reaction, therefore moles of H2 evolved = moles Mg consumed and the atomic weight of Mg = weight of Mg consumed..
The temperature of Beaker X = 75°C and the temperature of Beaker Y = 50°C after Five minutes . determine the temperatures be after another 5 minutes have passed?
The flask is not only completely filled with vapor, but some liquid also remains in the bottom of the flask when it is removed from the hot water bath and cooled in part B3. How will this oversight affect the reported molar mass of the liquid.
The average distance between planet X and Earth is about 2.59 x 108 miles. How long (minutes) would it take pictures transmitted from a space vehicle on Planet X's surface to reach Earth
