Answer:
Ionic compounds are electrically neutral because the positive ions and the negative ions in the compound cancel each other.
Explanation:
Ion- It is an atom or a molecule that has an equal number of protons (subatomic particles with positive electric charge) and electrons (subatomic particles with negative electric charge).
Positive ion- This is also called a "cation." It consists of more protons than electrons.
Negative ion- This is also called an "anion." It consists of more electrons than protons.
Ionic compounds are electrically neutral because they consist of anions and cations. This neutralizes the compounds. A common example of ionic compound is the NaCl (Sodium Chloride). The Na (Sodium) atom loses an electron in order to become Na+ while the Cl (Chlorine) atom gains an electron in order to become Cl-. This interaction balances them together.
NaCl= sodium chloride or salt
KBr= potassium bromide
Answer:
1 . 26
2. 55.854
Explanation:
because atomic number is the number of proton in other words smaller number and the mass number is the number of neutrons and electrons in other words bigger number .
hope this make sense :)
Answer:
The pH of the buffer solution is 7.236
Explanation:
Henderson - Hasselbalch equation of a buffer solution consisting of a weak acid and its conjugate base is given as:
The hypochlorous acid (HCIO), is the weak acid and the conjugate base the hypochlorite anion (ClO⁻) is the conjugate base.
The dissociation of the salt is given by:
NaOCl(aq) ⇒ Na⁺(aq) + ClO⁻(aq)
The salt dissociate at a ratio of 1:1
Substituting values to get:
The pH of the buffer solution is 7.236
He should buy the sander in store, this way it will be available for when he needs it.
