The solution would be like this for this specific problem:
4 NaOCl + S2O3{2-} + 2
OH{-} → 2 SO4{2-} + H2O + 4 NaCl
<span>(0.00456 L) x (0.100 mol/L
S2O3{2-}) x (4 mol NaOCl / 1 mol S2O3{2-}) x (100.0 mL / 25 mL) x </span><span>
<span>(74.4422 g NaClO/mol) = 0.54313 g </span></span>
<span>(5.00 mL) x (1.08 g/mL) =
5.40 g solution </span>
(0.54313 g) / (5.40 g) =
0.101 = 10.1%
So, the average percent by mass of NaClO in the
commercial bleach is 10.1%.
Answer:
option b= 1.26 mol/L
Explanation:
Given data:
moles = 2.34 mol
volume = 1860 mL
Solution:
molarity = moles of solute/ volume in L
First of all we will convert the mL in L,
1860 mL / 1000 = 1.86 L
now we will put the values in formula,
molarity = 2.34 mol / 1.86 L
molarity = 1.26 mol/L
Answer:
The answer is D, organisms that are mostly related belong in a species.
Explanation:
C) The atom must contain some centrally located positive charge. He called this core of positive charge the nucleus.
Explanation:
Rutherford concluded from his experiment that the atom contains some centrally located positive charge. He called the core the nucleus.
Rutherford developed the nuclear model of the atom.
- In a bid to explain his observation, Rutherford suggested the nuclear model.
- The model consists of small positively charged center called the nucleus.
- Nearly all the mass is concentrated in the nucleus.
- The extranuclear space is made up of electrons orbiting the nucleus.
