1). What they have in common is the proliferation of porphyry deposits, but they differ in lower crust lithology which includes granulite, hornblendite, and gabbro. Using geochemical and isotopic results, we investigate the Cu budget and isotopic composition of the lower continental crust and ...
1).Write a balanced equation for the reaction of calcium phosphide,Ca3P2,withwater,H2O,forming calcium hydroxide,Ca(OH)2 and phosphine,PH3.Calculate theheat of reaction from the standard heats of formation listed below.Thencalculate the standard enthalpy change when 39.4 grams of calcium phosphide...
CuO(s) + 2HCl (2q)---CuCl2(aq) + H2O (l) Now the equation is correct. It tells us that each compound has two different types of atoms. During the reaction, these atoms have“changed patterns”, so to speak, and new arrangements have been formed to produce different compounds. We...

Precipitation-based assessments show a lengthening of tropical dry seasons under climate change, without considering simultaneous changes in ecosystem water demand. Here, we compare changes in tropical dry season length and timing when dry season is defi
K2MnO4 + MnO2 + O2 arrow 15. Hydrogen peroxide decomposition reaction under the catalyst of manganese dioxide: H2O2 MnO22H2O + O2 (laboratory oxygen principle 3) 2. Water in nature: 16. Water is decomposed under the action of direct current (the study of water composition experiment) : 2H2...
The spectroscopic features of protonated water species in dilute acid solutions have been long sought after for understanding the microscopic behavior of the proton in water with gas-phase water clusters H+(H2O)n extensively studied as bottom-up model systems. We present a new protocol for the ca...
In the presence of sunlight, chlorophyll (a pigment found in chloroplasts) captures energy and converts it into chemical energy, which is used to convert carbon dioxide and water into glucose. Oxygen is released as a byproduct. The overall equation for photosynthesis is: 6CO2 + 6H2O + ...
