Answer is: +113.
Nihonium<span> is a </span>chemical element<span> with symbol </span>Nh<span> and </span>atomic number 113. It has 113 protons (<span>positive </span>electric charge<span> of +1</span>). P<span>rotons, beside neutrons (neutral charge), are in the </span>nucleus<span> of every </span><span>atom. Because only protons in nucleus have charge, charge of element-113 is +113.</span>
The answer should be a) always six. The chemical reaction is the process of molecule break down and form again. So the molecule will change but the atom will not change both type and number.
Answer:
The answer is
<h2>0.15 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 13.57 g
volume = 89.6 mL
The density is
We have the final answer as
<h3>0.15 g/mL</h3>
Hope this helps you
The net ionic equation is
Cu(s) + 4H⁺(aq) + 4NO₃⁻(aq) ⟶ Cu²⁺(aq) + 2NO₃⁻(aq) + 2NO₂(g) + 2H₂O(ℓ)
<em>Molecular equation
:</em>
Cu(s) + 4HNO₃(aq) ⟶ Cu(NO₃)₂(aq) + 2NO₂(g) + 2H₂O(ℓ)
<em>Ionic equation:
</em>
Cu(s) + 4H⁺(aq) + 4NO₃⁻(aq) ⟶ Cu²⁺(aq) + 2NO₃⁻(aq) + 2NO₂(g) + 2H₂O(ℓ)
<em>Net ionic equation
</em>
Cu(s) + 4H⁺(aq) + 4NO₃⁻(aq) ⟶ Cu²⁺(aq) + 2NO₃⁻(aq) + 2NO₂(g) + 2H₂O(ℓ)
<em>Note</em>: The net ionic equation is <em>the same as </em>the ionic equation because there are <em>no common ions</em> to cancel on opposite sides of the arrow.
