Ammonia is a weak base that ionizes to a limited extent in aqueous solution. The extent to which a weak base ionizes in aqueous solution is given by percent ionization. The formula percent ionization is given below. {eq}\rm \%\ ~ ionization~=~\frac{BH^+_{eq}}{C_{B}}\time...
Complete step by step answer:As we know that there are two types of reactions one is endothermic and other is exothermic based upon the amount of energy released or amount of energy consumed to form or break the new bond in formation of new compounds from the reactant...
theavp1mutant plants retained similar Mg content to wild-type plants under either normal or high Mg conditions, suggesting that AVP1 may not directly contribute to Mg2+homeostasis in plant cells. Further analyses confirmed that theavp1mutant plants contained a higher pyrophosphate (PPi) content than...
Anhydrous ammonia is a cheaper source of nitrogen (N) fertiliser than granular urea for rice production, but it is not widely used in developing countries. It can only be applied pre-crop with any in-crop applications being applied in the form of urea. This 2-year study conducted in the ...
1 tablespoon (15 ml) of contact lens solution or saline solution (this must contain boric acid and sodium borate) 1 bowl and spoon Measuring cup Instructions: Pour the glue into a bowl. Measure out the baking soda. Add to glue and mix thoroughly. Mix in the contact lens solution. Keep...
However, more severe exposures, such as those caused by an acid (like pool or battery acid) or an alkali (like ammonia or drain cleaner), should be thoroughly flushed with water while emergency care is sought. This is especially true with alkali burns which, even more than acid, can sever...
Prepare 200 mL of 0.4 M ammonia from a 25% solution. What is the initial concentration and volume? Solute Concentration: Many reactants or products in chemical reactions are present as solutions. This consists of the substance as a solute dissolved in a cer...
