Right
When you mix limewater (calcium hydroxide solution) with hydrogen gas, no immediate reaction occurs. However, over time, the hydrogen gas may dissolve in the limewater forming a very small amount of hydrogen hydroxide. This reaction is very slow and may not be observed in real time.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
sodium and water =sodium + water -> sodium hydroxide + hydrogen and this is the right answer because i got it of a scientist
Hydrogen can be obtained through various methods such as electrolysis of water, steam methane reforming, and biomass gasification. These processes involve extracting hydrogen from water, natural gas, or biomass, respectively. Additionally, hydrogen can also be produced from renewable sources like solar and wind energy through electrolysis.
That depends on what chemicals were mixed in order to produce the hydrogen gas. For example, if it was the metal magnesium (Mg), and the acid hydrochloric acid (HCl), then the equation would be Mg(s) + 2HCl(aq) -- > MgCl2(aq) + H2(g). Please note that the 2 after MgCl is supposed to be a subscript, as is the 2 after hydrogen. We are having difficulties with the subscripts and superscripts right now.
Right
Hydrogen can be a reactant or a product, it depends on the chemical reaction. Anything to the left of the arrow is consumed by the reaction and is thus a reactant, so hydrogen is a reactant in the reaction O2 + 2H2 -> 2H2O. A product is on the right of the arrow and is produced by the reaction, so hydrogen is a product in the reaction Zn + 2HCl -> ZnCl2 + H2
i think it's a combustion reaction because heat is involved. hope it's right
Products are at the right side --> hydrogen H2 and oxygen O2
This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced
It depends on the reaction. Also, only the products are produced by a chemical reaction; the reactants produce the reaction and are changed in the reaction to the products. (If you have a chemical equation, the number of distinct molecules and/or isolated element symbols on the right side of the equation will show how many distinct products are formed in the reaction.)
The new substance that are produced
The reaction between aluminum (Al) and sulfuric acid (H2SO4) to form aluminum sulfate (Al2(SO4)3) and hydrogen gas (H2) is a single displacement or single replacement reaction. In this reaction, aluminum displaces hydrogen from sulfuric acid to form aluminum sulfate and hydrogen gas is formed as a byproduct.
The reaction of an acid and an alkali in the right amounts is called neutralization. In this reaction, the acid's hydrogen ions combine with the alkali's hydroxide ions to form water and a salt.
Reactants- The substances used up in a reaction. Products- The new substances made.
The side on the left of a chemical equation is the reactants, the chemicals consumed by the reaction. The side on the right is the product, the chemicals produced by the reaction.
Hair growth reduction is the side effect of laser hair removal. You may experience irritations right after the treatment due to the skin reaction, this is normal for this kind of treatment.
