Explanation:
The reaction expression is given as;
2H₂
+ O₂ → 2H₂O
From the balance reaction expression:
2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;
This produces 2 mole of water on the product side of the expression.
The product is in liquid form.
This reaction is a synthesis reaction because a single product is formed from two reactants.
Answer is: <span>A. 1 molecule with 10 atoms.
Every ball represent one atom in one molecule.
</span><span>The </span>ball and stick model<span> is a </span>molecular model<span> of a </span>chemical substance<span> that shows the </span>three-dimensional<span> position of the </span>atoms<span> and the </span>bonds between them. <span>The atoms have spherical shape and they are </span><span>connected with sticks (one, two or three, depends on bonds).</span>
elements are classified to study their properties and similarities and differences between each other more aqurately
hope it helps...!!!!
The energy of a photon : 7.645 x 10⁻³⁴ J
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
, Hz
c = speed of light
= 3.10⁸ m/s
λ = wavelength
,m
wavelength λ of 2.60 ✕ 10⁻⁸ m
The energy :
