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>
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.
<u>Answer:</u> The number of neutrons in boron are 6.
<u>Explanation:</u>
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons present in an atom.
Mass number = Number of neutrons + Number of protons.
We are given:
Mass number = 11
Atomic number of boron = 5
Number of neutrons = Mass number - Atomic number = 11 - 5 = 6
Hence, the number of neutrons in boron are 6.
Answer:
Number of moles of Fe = 10 mol
Number of moles of CO₂ = 15 mol
Explanation:
Given data:
Number of moles of iron oxide = 5 mol
Number of moles of carbon monoxide = 25 mol
Number of moles of product = ?
Solution:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Now we will compare the moles of reactant with product.
Fe₂O₃ : Fe
1 : 2
5 : 2×5 = 10 mol
Fe₂O₃ : CO₂
1 : 3
5 : 3×5 = 15 mol
CO : Fe
3 : 2
25 : 2/3×25 = 16.7 mol
CO : CO₂
3 : 3
25 : 25
Less number of moles of Fe and CO₂ are formed by iron oxide thus it will act as limiting reactant while CO is inn excess.
