Answer:
NO₃⁻.
Explanation:
- Spectator ions are the ions that is present in the same form on both sides of a chemical equation (do not change).
For the reaction: Mg(s) + Zn²⁺ + 2NO₃⁻ → Mg²⁺ + 2NO₃⁻ + Zn(s),
- The reactants' side contains two ions
: Zn²⁺ and NO₃⁻.
- Also, the product's side also contains two ions
: Mg²⁺ and NO₃⁻.
<em>Because the nitrate anions are present on both sides of the equation, they are spectator ions.</em>
Why are open systems inappropriate for studying the conservation of mass?? The sample may become contaminated. Matter may be created or destroyed within the system. Heat can escape from or enter the system. Matter may be lost to or gained from the surroundings.
The rate of formation of water and the decomposition of hydrogen peroxide is double as compared to rate of formation of oxygen.
<h3>What is chemical reaction?</h3>
The chemical reaction is given as the reaction of the reactants in the process to form the new compound.
The chemical reaction with the decomposition of hydrogen peroxide is:
The rate of formation of water is given to be double the rate of formation of oxygen as 2 moles of water formed with 1 mole of oxygen.
The rate of disappearance of hydrogen peroxide is double with formation of oxygen as for decomposition of 2 moles of hydrogen peroxide, 1 mole of oxygen is formed.

Answer:
yes
Explanation:
they di because they have mass and wait
Answer:
<h3>The answer is 13.87 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of metal = 5.78 g/mL
volume = final volume of water - initial volume of water
volume = 24.7 - 22.3 = 2.4 mL
We have
mass = 5.78 × 2.4 = 13.872
We have the final answer as
<h3>13.87 g</h3>
Hope this helps you
