<span>This is a false statement. The negatively charged particles that orbit the nucleus are called electrons. They are what balance out the protons, giving the element an overall neutral charge. They are also the parts of the atom that bond to other elements, which lead to molecules and other compounds.</span>
Answer:
44.01 g/mol because its basically the weight
Explanation: 12.0107 + 15.9994*2
Potassium chloride reacts with ammonium nitrate to give ammonium chloride and potassium nitrate.
This is a type of double displacement reaction. The balanced chemical equation can be represented as,
Total ionic equation for this reaction will be,
There is no apparent reaction as this reaction is not accompanied by the formation of a gas or a solid precipitate. We cannot observe any visual reaction as there is not net reaction taking place. All the ions remain as spectator ions.
4 moles of NaOH is present in the given 160 grams of NaOH.
<h3>How we calculate moles?</h3>
Moles of any substance will be calculated as:
n = W/M, where
W = given mass of NaOH = 160 grams (given)
M = molar mass of NaOH = 40 g/mole
Moles of NaOH is calculated as:
n = 160g / 40g/mol = 4 moles
Hence, moles of sodium hydroxide (NaOH) is 4 moles.
