<span>In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. Balanced chemical equation for this reaction is given below.
Na-sodium , H2o- water, H-hydrogen gas and NaOH- aqueous sodium hydroxide.
Two atoms of Na react with two atoms of water and this reaction will give us H (hydrogen gas) and two atoms of NaOH (aqueous sodium hydroxide).
2Na + 2 H2o = H2 +2NaOH.</span>
Answer: A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products
Answer:
La materia está constituida por átomos, que a su vez forman moléculas. Las moléculas constituyen la mínima parte en la que se puede fragmentar una sustancia para que conserve sus propiedades. Todo lo anterior permite que la materia se pueda presentar en estado sólido, líquido y gaseoso.
Explanation:
Answer:
wavelength λ = 35.92 pm
Explanation:
Given that:
The glancing angle (θ) = 10.42°
Bragg reflection n = 1
wavelength λ = ???
diameter d = 99.3 pm
Using the formula:
nλ = 2dsinθ
we have:
1 × λ = 2 × ( 99.3) × sin (10.42°)
λ = 198.6 × 0.18086
λ = 35.92 pm
