Question

Name the three metals which react with cold water to form hydrogen gas. Support your answer with equally balanced chemical equations.

Answer 1

Hint: Water is made out of two hydrogen molecules and an oxygen iota. It displays extremity and is normally found in the fluid, strong, and fume states. Its extremity makes it a decent dissolvable and is ordinarily known as the general dissolvable.

Complete step by step answer:
Na, K, Rb reacts readily with water to form hydrogen gas & corresponding hydroxide.
\[\begin{array}{*{20}{l}}
  {2Na + 2{H_2}O \to 2NaOH + {H_2} \uparrow } \\
  {2K + 2{H_2}O \to 2KOH + {H_2} \uparrow } \\
  {2Rb + 2{H_2}O \to 2RbOH + {H_{2}} \uparrow }
\end{array}\]
Substance conditions are emblematic portrayals of compound and actual changes. Equations for the substances going through the change (reactants) and substances created by the change (items) are isolated by a bolt and went before by number coefficients showing their relative numbers. Adjusted conditions are those whose coefficients bring about equivalent quantities of particles for every component in the reactants and items.
Compound responses in fluid arrangements that include ionic reactants or items might be addressed all the more sensibly by complete ionic conditions and, all the more compactly, by net ionic conditions. In a reasonable substance condition, the absolute number of iotas of every component present is the equivalent on the two sides of the condition. Stoichiometric coefficients are the coefficients needed to adjust a synthetic condition.
These are significant on the grounds that they identify with the measures of reactants utilized and items shaped. The coefficients identify with the harmony constants since they are utilized to compute them. Hence, it is critical to see how to adjust a condition prior to utilizing the condition to ascertain harmony constants.

Note: A substance condition is a synthetic equation that gives the data of the components and particles that are responding just as the atoms that are being delivered from that response.
