Metals: potassium, magnesium, aluminum, calcium, iron (forming Fe2+ ions)
Al(OH)3 + 3NaNO3 >> Al(NO3)3 + 3NaOH This is a double displacement reaction between metals ( Aluminum is a transition metal, but has only a 3+ oxidation state. ) and polyatomic ions of negative charge. Both are 1- in charge. Sodium is 1+ in charge. This is why the atoms are arranged as they are with the polyatomic ions enclosed in parentheses where needed. Remember, botgh sides of the equation musr contain the same number of atoms. Count carefully and you will see this is the case.
calcium carbonate reacts with acids ,How ? when calcium carbonate reacts with a dilute acid it will form the corresponding salt and water .will also release carbon dioxide. e.g. CaCO 3 + H Cl --> Ca Cl 2 + C O2 +H2O EDIT: The above chemical equation is not balanced... Here's the balanced equation: CaCO3 + 2HCl -> CaCl2 +CO2 + H2O Calcium Carbonate reacts with Hydrochloric acid to form Calcium Chloride, Carbon dioxide, and water.
In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
They react with a oxydation reaction , forming oxydes. For example: Iron (Fe) reacts with the equation, 2 Fe(s) + O2(g) + 2 H2O(l) = 2 Fe(OH)2(s) Fe(OH)2 is rust. or with the formation of hydroxides: 2 Na + 2 H2O = 2 NaOH + H2
metal : potassium behavior: catches fire immediately with only a little heating. Burns fiercly with a lilac flame. product : potassium oxide equation: K2O equation: K+O2------->K2O
The balanced chemical equation for the reaction of aluminum with hydrochloric acid (HCl) to form hydrogen gas (H2) and aluminum chloride (AlCl3) is: 2 Al + 6 HCl → 2 AlCl3 + 3 H2
Assuming it's copper(II) oxide, the equation for that reaction is: CuO + H2 --> H2O + Cu. Reactants: copper oxide and hydrogen gas. Products: Water and copper. Elements present: hydrogen, copper. Compounds present: copper oxide, water. Metals: copper. Non-metals: hydrogen.
This reaction would not take place. In Chemistry, there is a list called the Activity Series that dictates which metals can replace others in single and double replacement reactions. Hydrogen is more reactive than copper and thus the copper will not be able to react with the Hydrogen Peroxide.
When manganese dioxide is heated with aluminium powder, the following reaction takes place: These displacement reactions are highly exothermic. The amount of heat evolved is so large that the metals are produced in the molten state. On the other hand when manganese is heated with aluminum oxide no reaction takes place as aluminum is more reactive than manganese and is placed higher in the activity series.
Alkali metals, for example: 2Me + 2H2O = 2MeOH + H2 Me is the metal
Al(OH)3 + 3NaNO3 >> Al(NO3)3 + 3NaOH This is a double displacement reaction between metals ( Aluminum is a transition metal, but has only a 3+ oxidation state. ) and polyatomic ions of negative charge. Both are 1- in charge. Sodium is 1+ in charge. This is why the atoms are arranged as they are with the polyatomic ions enclosed in parentheses where needed. Remember, botgh sides of the equation musr contain the same number of atoms. Count carefully and you will see this is the case.
Cu + MgCl2 --> no reaction In order for a single replacement/displacement reaction to take place, the free metal must replace the bonded metal in the compound. However, according to the reactivity series of metals, copper does not replace magnesium, however magnesium would replace copper in a compound. Mg + CuCl2 --> Cu + MgCl2. Refer to the related link for a reactivity series of metals.
Ab+cd > ad+cb. A and c are the metals or the positive ion
The most common set of metals that react with water at room temperature are the alkali metals, namely lithium, sodium, potassium, rubidium, cesium, and francium. while these metals react quite violently with water at room temperature, many if not most other metals have some sort of reaction with water at room temperature (IE, iron rusting in water)
No reaction happens. Only way to get a reaction going is if you have two molecules with different Metals and Non-metals. Metals in this one are different but non-metals are not so no reaction.

yes, it would occur because iron is more reactive than copper (look at an activity series to see this). metals trade places in a single replacement reaction if the metal that is alone on the reactact side of the equation has a higher reactivity than the metal attached to the nonmetal. It doesnt seem like you were answering THIS question??
