For which of the following reactions is ΔH∘rxn equal to ΔH∘f of the product(s)? You do not need to look up any values to answer this question. Check all that apply. Check all that apply. H2O2(g)→12O2(g)+H2O(g) Li(s)+12Cl2(l)→LiCl(s) 2Li(s)+Cl2(g)→2LiCl(s) 2H2(g)+O2(g)→2H2O(g) Li(s)+12Cl2(g)→LiCl(s) H2(g)+12O2(g)→H2O(g) I need to get an understanding of how its done.
In this experiment, you will first change the temperature of the water and determine its effect on the time it takes the tablet to dissolve. Then you will alter the size of the antacid tablet and determine its effect on the time it takes the tablet to dissolve. In the space below, write a scientific […]
When you chew your food to break down the larger pieces into smaller particles, how are you helping to increase the rate of the chemical reactions in your body that breaks down your food?
Find the pressure in mm Hg produced by 2.35g of carbon dioxide in a 5.00L flask at 18 degrees Celsius.
Chemical weathering occurs faster in warm, tropical climates, although it happens in cold climates as well. Describe some conditions in Antarctica that could lead to chemical weathering.
How are carbon dioxide (co2) levels in the atmosphere affected by tectonic uplift of rocks and their resultant chemical weathering?
Consider the following reaction. H2O + F– <—> HF + OH– What is the conjugate base of H2O? a) H2O b) F– c) OH–
What did rutherfords alpha scattering experiment suggested? c. all atoms are positively charged particles d. the size of the atom is equal to the size of the nucleus
What is the formula equation for the reaction between sulfuric acid and dissolved sodium hydroxide if all products and reactants are in the aqueous or liquid phase?
Incineration and landfills are the most widely-used waste management methods. Incineration is the burning of garbage and is favored by small countries that lack adequate landfill space. This method can, however, have a major impact on the environment. What is a possible problem with incineration of waste materials as a method of disposal?
