Answer:
it depends on how you use action Because action means you are doing something and maybe action like reaction or something like a feeling if a bomb occurs that is the action.
Explanation:
a) Barium
b) The metalloid in third period is Silicon
c) Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C)
d) At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
e) osmium
f) chlorine (Cl, element 17) are a gas at room temperature, and is found as diatomic molecule (Cl2).
The precision of a tool can affect the measurement's accuracy. how specific the measurement can get (if it goes to the tenths place, hundredths, etc) can also affect the accuracy.
The balanced equation for the above neutralisation reaction is as follows;
2KOH + H₂SO₄ --> K₂SO₄ + 2H₂O
stoichiometry of KOH to H₂SO₄ is 2:1
neutralisation is the reaction between H⁺ ions and OH⁻ ions to form water which is neutral
number of KOH moles - 1.56 mol
2 mol of KOH require 1 mol of H₂SO₄ for neutralisation
therefore 1.56 mol of KOH require - 1/2 x 1.56 mol = 0.78 mol
0.78 mol of H₂SO₄ are required for neutralisation
