Please answer al three questions. Thank you!! I Review I Constants I Periodic Table When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of Part A mass. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of...
Solid magnesium reacts with aqueous phosphoric acid to produce magnesium phosphate and hydrogen gas. The balanced chemical equation is: 3Mg(s) + 2H3PO4(aq) → Mg3(PO4)2(s) + 3H2(g) Calculate the moles of hydrogen gas you want to produce (do not express your answer in scientific notation
Write a balanced chemical equation for each reaction. MgSO4(s)+7H2O(l) -> magnesium sulfate bubbles &produces heat when it comes in contact with distilled water. P2O5(s)+ H2O(l) -> diphosphorus pentoxide sizzled when came in contact with water, blue litmus turned red. H2O(l)+Ca(s) -> Calcium bubbles in the water, leaving a white powder at the bottom of the beaker. Mg(s)+H2O(l) -> Turns a light clear yellow (indicator) heat changes the color to blue, unheated turns the color to purple. 2HCL(aq)+Mg(s) -> H2(g) +...
A sample of magnesium metal reacts completely with water via the following reaction: Mg (s) + 2 H2O (l) → Mg(OH)2 (aq) + H2 (g) The hydrogen produced is collected over water at 25.0°C. If the volume of the gas is 7.80L and the pressure is 0.980 atm, calculate the mass of magnesium metal reacted. (Pwater @ 25.0°C = 23.8 mm Hg)
