2H₂ + O₂ ⇒ 2H₂O
<h3>Further explanation</h3>
Conservation of mass states that
<em>In a closed system, the masses before and after the reaction are the same</em>
So it can be concluded
- mass of the reactants = mass of the products
- mass cannot be created or destroyed
- The number of atoms involved in a reaction remains the same⇒ number of moles also the same
- chemical equation in balanced form
So let's see which of the several options , which one has the same number of atoms on both sides of the equation
2H₂ + O₂ ⇒ 2H₂O
H ⇒ left 4, right 4
O ⇒ left 2, right 2
so the equation is in balance and represents the Law of Conservation of
Mass
I need energy because in how much hard homework teachers give us
Cr₂O₃ ( s ) + 3H₂S ( g ) → Cr₂S₃ ( s ) + 3H₂O ( l )
mol Cr₂S₃ = 421 : 200.19 g/mol = 2.103
mol Cr₂O₃ ≈ mol Cr₂S₃ = 2.103 ( equivalent coefficient)
mass Cr₂O₃ = 2.103 x 151.99 g/mol = 319.63 gr
I’m thinking C for this hope it’s right
Answer:
Clarity and precision - these names are unique with each creature having only one scientific name. Helps avoid confusion created by common names. 3. Universal recognition - scientific names are standardised and accepted universally
