What is the predicted general formula for the compound formed between an alkali metal and sulfur?
The predicted general formula for the compound formed between an alkali metal and sulfur is M2S, where M represents the alkali metal cation. Alkali metals typically have a +1 charge, and sulfur usually forms a -2 anion, leading to the 2:1 ratio in the compound formula.
What consists of a pulp or paste made by heating chopped fresh dried or powdered herbs with a little water?
An herbal decoction consists of heating chopped fresh, dried, or powdered herbs with a little water to create a pulp or paste. This method helps extract the medicinal properties of the herbs for various therapeutic purposes.
What is the elements make up in iron phyrophosphate?
Pyrophosphate has the chemical formula (P2O7)-4. It is a class of chemical anions that were originally formed from heating (pyro) phosphates. They are formed by esterification of two phosphates (linking them with one of the phosphate oxygen atoms).
Why is that bad to use powdered lime to heat food?
Powdered lime is not safe for consumption as it is a chemical compound used in construction. It can be harmful if ingested and should not be used to heat food. Instead, use food-grade materials such as salt, sugar, or baking soda for cooking or heating food.
Is the heating of a solution of powdered milk a chemical change?
If it is a chemical change it will have a change in color (not meaning food coloring was added) precipitate (solid) was formed, release of gas, new substance was formed, temperature change. If something is baked it was a chemical change
What s the formula f the predicted product from heating potassium metal an powdered phosphorus?
K3P, potassium phosphide. This is the one that is most likely to be predicted. It contains the P3- ion. Note that potassium actually has nine binary phosphides , (K3P, K4P3, K5P4, KP, K4P6 K3P7, K3P11, KP10.3, KP15 Before heat the metal and phosphorus (under vacuum and with extreme care) I would weigh out the reactants in exactly the correct proportions to minimise the potassium rich or phosphorus rich compounds.
What is the predicted general formula for the compound formed between an alkali metal and sulfur?
The predicted general formula for the compound formed between an alkali metal and sulfur is M2S, where M represents the alkali metal cation. Alkali metals typically have a +1 charge, and sulfur usually forms a -2 anion, leading to the 2:1 ratio in the compound formula.
What is the formula of the predicted product from heating magnesium metal and nitrogen gas?
The predicted product from heating magnesium metal and nitrogen gas is magnesium nitride (Mg3N2). This is formed by the reaction between magnesium metal and nitrogen gas, following the general equation: 3Mg + N2 → Mg3N2.
What is formed by heating phosphorus with oxygen gas?
Do you mean heating Phosphorus THEN putting it in oxygen gas? Because the reaction that will create is glowing and also condensation that causes vapor. The description of the gas is opaque and white. Not really sure what the gas is tho...
How can white phosphorus be made?
White phosphorus can be made by heating phosphate rock with carbon and silica in a furnace, which causes the phosphorus to vaporize and then condense into a solid form.
Can you put formula in the microwave for heating"?
No, it is not safe to put formula in the microwave for heating.
Preparation of phosphorus and nitrogen in the laboratory?
Phosphorus can be prepared in the laboratory by heating white phosphorus in a closed vessel without oxygen. Nitrogen can be prepared by heating ammonium nitrite. Both processes should be carried out in a fume hood due to the potentially hazardous nature of the substances involved.
How can red phosphorus powder be made?
Red phosphorus powder can be made by heating white phosphorus in the absence of air at a temperature of around 250 degrees Celsius. This process causes the white phosphorus to undergo a chemical transformation, turning it into red phosphorus powder.
Why can't solid phosphorus can not be melted by heating in a container?
Solid phosphorus sublimes when heated, meaning it changes directly from a solid to a gas without going through a liquid phase. This is due to the weak van der Waals forces between the phosphorus molecules, which are not strong enough to hold them together in a liquid state.
Where was phosphorus first discovered?
Phosphorus was discovered in 1669 in Germany by a man named Hennig Brand.
How can one make phosphorus?
Phosphorus can be made through a process called the thermal decomposition of calcium phosphate. This involves heating calcium phosphate with silica and carbon in a furnace to produce phosphorus vapor, which can then be condensed into a solid form.
When did Henning Brand discover phosphorus?
Henning Brand discovered phosphorus in 1669
