Answer:
0.133
Explanation:
reaction between KIO3 and KI in acidic medium
IO3⁻ +5I⁻ +6h⁺ → 3I₂ + 3H₂O
I₂ reacts with thiosulphate
NaS₂O₃ → 2Na⁺ + S₂O₃²⁻
net reaction
IO⁻₃ + 6H⁺ + 6S₂O₃³⁻ → I⁻ + 3S₄O₆²⁻ + 3H₂O
mole of KIO₃
= molarity x volume
= 0.00002mol
a mole of KIO₃ has reaction with 6 mol of S₂O₃²⁻
= 2x6x10⁻⁵
= 0.00012 mol
volume = 0.90 ml
1 ml = 0.001L
0.90ML = 0.0009L
to get concentration,
molarity/volume
= 0.00012/0.0009
= 0.133m
a binary compound is a substance composed of exactly two different elements, which are substances that cannot be simplified further by chemical means.
Answer:
pressure will be high because the temp is high, the gas is gonna expand
Explanation:
when temp increases it causes gas to expand which causes high pressure. this is because pv=nrt, p=pressure in atmosphere, v is volume in liters, n is number of particles in moles, t is temp in kelvin is r is ideal gas constant
The correct answer for the given question above would be option B. HYDROGEN. The form that has the greatest number of <span>strong covalent bonds and is therefore the backbone of organic molecules including carbohydrates, proteins, lipids and nucleic acids is HYDROGEN.
