Avagadro's law gives the relationship between volume of gas and amount of moles of gas. It states that at constant temperature and pressure, volume of gas (V) is directly proportional to number of moles of gas (n).
V/n = k
where k - constant
V1 = 42.0 L
n1 = 1.90 mol
n2 = 1.90 mol - 0.600 = 1.30 mol
substituting the values in the equation
V = 28.7 L
Volume of the gas is 28.7 L
Answer: Getting into the technicalities, the continental crust has a density of around 3.0 g/cm3 compared to 2.6 g/cm3 of the continental crust. In addition, the continental crust is much thicker than the oceanic crust.

This should be the right answer, let me know if its not so i can know for future.
Answer:
iron (Fe)
Explanation:
Since an atom is electrically neutral, so the atom has 26 electrons also. Ion has 24 electrons, so it has experienced loss of 2 electrons. So, charge on ion is +2. Also, the element with 26 protons (26 atomic number) is iron (Fe).
Answer:
chemical changes that happen when food goes bad. All food will eventually rot if not eaten, but keeping the food cold slows the rotting process. Chemical changes are affected by temperature. More heat or energy (a higher temperature) usually allows for faster chemical changes.
