The balanced net iconic equation :

  • (a) 2HNO3 (aq) Ba(OH)2 (aq) Ba(NO3) (aq) + 2H20
  • (b) HF(aq) + K+(aq) + OH-(aq) → K+(aq) + F-(aq) + H2O(l) Net: HF(aq) + OH-(aq) → H2O(l) + F-(aq)
  • (c) C6H5NH2 + HClO4 → ClC6N + 4H2O
<h3>Briefing :</h3>

Salt and water are created when an acid and a base interact then Acid-based reaction happens. Because both water and salt are neutral, if an acid and a base react together, they cancel out each other's effects. It is referred to as a neutralization reaction as a result.

<h3>What is acid-base reaction?</h3>

An acid-base reaction is a chemical reaction involving an acid and a base.

H+ and OH- ions are produced by bases and acids, respectively, and these ions combine to make water. There are a number of drawbacks to the Arrhenius theory. Because it defines acids and bases in terms of what occurs when compounds dissolve in water, it can only be applied to reactions that take place there.

One or more hydrogen ions, H+, are exchanged between entities that may be neutral (such as H2O) or electrically charged (ions-ammonium, NH4+; hydroxide, OH; or carbonate, CO32); in an acid-base process.

Why this chemical equation 3P4 + 10O2 = 4P2O5 + P4 is wrong?
ad-work [718]

Because it can be balanced in an infinite number of ways so it would need to be rewritten in a simpler form.

Convert 8.50 moles Ca to atoms
Wewaii [24]

8.50 moles is equal to 5.1187×10²⁴ atoms of Ca.

<u>Explanation:</u>

We have to multiply the moles of Ca by the Avogadro's number:

= 6.022×10²³

So the number of atoms:

= 8.5 moles × 6.022×10²³atoms / mol

= 5.1187×10²⁴ atoms

Hence the 8.50 moles is equal to 5.1187×10²⁴ atoms of Ca.

Write the appropriate symbol for each of the following isotopes: (a) Z 74, A 186; (b) Z 80, A 201; (c) Z 34, A 76; (d) Z 94, A 2
beks73 [17]

Answer:  a)  _{74}^{186}\textrm{W}

b) _{80}^{201}\textrm{Hg}

c)  _{34}^{76}\textrm{Se}

d) _{94}^{239}\textrm{Pu}

Explanation:

General representation of an element is given as:_Z^A\textrm{X}

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

In an atom, when neutrons or protons are lost or gains, it directly affects the mass number of an atom.

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

It is characteristic of a particular element.

Atomic number = Number of electrons = Number of proton

a) Z 74, A 186: _{74}^{186}\textrm{W}

b) Z 80, A 201: _{80}^{201}\textrm{Hg}

c) Z 34, A 76: _{34}^{76}\textrm{Se}

d) Z 94, A 239.: _{94}^{239}\textrm{Pu}

How man grams of cl2 are consumed to produce 12.0 g of KCl
Korvikt [17]

Answer:

5.71 g

Explanation:

Step 1: Write the balanced equation

2 K + Cl₂ ⇒ 2 KCl

Step 2: Calculate the moles corresponding to 12.0 g of KCl

The molar mass of KCl is 74.55 g/mol.

12.0 g × 1 mol/74.55 g = 0.161 mol

Step 3: Calculate the moles of Cl₂ needed to produce 0.161 moles of KCl

The molar ratio of Cl₂ to KCl is 1:2. The moles of Cl₂ needed are 1/2 × 0.161 mol = 0.0805 mol

Step 4: Calculate the mass corresponding to 0.0805 moles of Cl₂

The molar mass of Cl₂ is 70.91 g/mol.

0.0805 mol × 70.91 g/mol = 5.71 g
