How many grams of water are needed to produce one hundred fifty grams of magnesium hydroxide?
Water ionises to a small extent to produce hydrogen ions an hydroxide ions according to the following reversible reaction: H20 <-> H+ + OH- Although, the reaction tends to lean towards the reverse reaction. It is still able to produce sufficient quantity of hydrogen ions and hydroxide ions needed to conduct electricity. Water conducts electricity through the migration of hydrogen and hydroxide ions.
firstly write out the BALANCED equation, or you're getting nowhere! : 3Mg(OH)2 + 2 H3PO4 ® Mg3(PO4)2 + 6 H2O Mol ratio :321 6 phosphoric acid: N = 2 according to the mol ratio 3 mols of the Magnesium Hydroxide will completely neutralise the Phosphoric Acid. Calc... We have 2mols of P.A and it mol ratio is two, divide it by 2 to give 1. as the mol ratio is 3 for magnesium hydroxide just…
A magnesium test checks the level of magnesium in the blood. Magnesium is an important electrolyte needed for proper muscle, nerve, and enzyme function. It also helps the body make and use energy and is needed to move other electrolytes (potassium and sodium) into and out of cells. Most of the magnesium in the body is found in the bones and inside the cells. Only a tiny amount of magnesium is normally present in the…
How many moles of ironIII hydroxide are needed to react with excess nitric acid to produce 63.8 g ironIII nitrate?
How many grams of solid barium hydroxide are needed to exactly neutralize 14.7 mL of a 0.597 M perchloric acid solution?
Magnesium is needed by plants to make the green pigment chlorophyll and to activate some enzymes. Although there may appear to be a lot of chlorophyll in plants, each chlorophyll molecule only contains one magnesium atom. The molecular weight of chlorophyll (in fact, chlorophyll a) is 893.5. The atomic weight of magnesium is 24.3. So magnesium only makes up about 2.7% of the weight of the chlorophyll. Enzymes are catalysts and are only needed in…
Magnesium ions are needed by plants to make chlorophyll Nitrate ions are needed by plants to make protein Additional info: Enzymes are protein in nature. it acts as catalyst to speed up chemical reaction without being used up at the end of the chemical reaction. Only small amount of enzymes are needed to catalyse (speed up) chemical reactions Thus, enzymes are needed in plants. because magnesium is a vital commponent for photosynthesis
In most instances, sodium hydroxide is sufficiently close in chemical properties to potassium hydroxide to make each one a substitute for the other. There are some exceptions, however, and more details about the "activation process" under consideration would be needed to give a more detailed answer.
