How do you solve step equations? H2CO3(aq) + NH4OH(aq) --- (NH4)2CO3(aq) + H2O(l) When balancing the equation why there is a coefficient in front of the "H" in H2O? The combustion of coal (burning of coal) is a redox reaction. Write overall equations to clearly show the re...
Hello, I have a quick question regarding my chemistry homework. I am currently working on stoichiometry and understand it pretty well, but it is always a challenge when I am asked to solve when given How to calculate relative molecular mass of a gas?
Answer to: How to calculate the slope, absorbance, and concentration of a best fit line once absorbance and concentration values are plotted on a...
4) under a totally different paradigm (based on his electron valence theory) and to solve a problem not contemplated by his contemporaries: acid-base behaviour in reactions without solvent, for example, in gas reactions. Fig. 4 Extract from electron valence theory book (Lewis 1923, p. 142) ...
Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The pho
members, NGO representatives and Ugandan authorities. The interviews took place in the Adjumani district, northern Uganda, specifically the Boroli and Alere settlements. We wanted to examine which disputes occur within and around the settlements and which actors intervene to mediate and solve them. ...
beexactlythe same for each person. You could come up with more than one way to make the final buffer solution for any given pH, so the lab is flexible depending on how you think about the problem.This type of lab encourages you to use knowledge of chemistry to solve a problem ...
Some common concepts do not remember, or several basic problem solving method is very important not apply, or some of the key knowledge of junior high school without a thorough understanding. Like Moore, the amount of substance concentration, redox reaction, and differential method, conservation ...
The proposed mechanism of progene formation allows us to solve, in a general form, the problem of constituent selection for the future genetic system. A trinucleotide is a minimal weak template, and formation of a complementary pair of imperfect “triplets” (Fig. 1) can only occur if all av...
How many grams of lead (II) nitrate must be dissolved in 1.00 L of water to produce a solution that is 0.300 M in total dissolved ions? Answer and Explanation: Lead (II) nitrate or Pb(NO3)2 is a strong electrolyte and dissociates almost c...
