Explanation:
An active ingredient sodium hypochlorite which gives the name to the compound bleach has both Hydronium ions and Hydroxide ions . In case of the hydronium ions the number of Ions that is present in bleach is About 1 /10 -12 while in case of Hydroxide ions the number of Ions present in breach are about 1/10-2 ions.
Hence from the numbers we can say the number of Ions that are more in bleach is that of hydroxide having a difference of about 10 ions.
<h3><u>Answer;</u></h3>
New information changed the understanding of the atom’s structure.
<h3><u>Explanation;</u></h3>
- <em><u>Mendeleev is know as the Father of the Modern Periodic Table. His table allowed scientists to predict the existence of elements that hadn't been discovered.</u></em>
- Mendeleev saw that when the elements were arranged in order of increasing atomic mass, those that had similar properties occurred in a repeating pattern. He predicted that elements yet to be found would fill the gaps in his table.
Answer:
100 celsuis
Explanation:
because it melts faster at a 100 degrees Celsius.
Answer:
0.86 g
Explanation:
Given:
Pressure = 725 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 725 / 760 atm = 0.9539 atm
Volume = 225 mL = 0.225 L (1 mL = 0.001 L)
Temperature = 25 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
0.9539 atm × 0.255 L = n × 0.0821 L.atm/K.mol × 298.15 K
⇒n = 0.0099 moles
From the reaction,
![MnO_2_{(s)}+4HCl_{(aq)}\rightarrow MnCl_2_{(aq)}+2H_2O_{(l)}+Cl_2_{(g)}](https://tex.z-dn.net/?f=MnO_2_%7B%28s%29%7D%2B4HCl_%7B%28aq%29%7D%5Crightarrow%20MnCl_2_%7B%28aq%29%7D%2B2H_2O_%7B%28l%29%7D%2BCl_2_%7B%28g%29%7D)
1 mole of chlorine is formed from 1 mole of ![MnO_2](https://tex.z-dn.net/?f=MnO_2)
Thus, moles of
= 0.0099 moles
Molar mass of
= 86.9368 g/mol
Mass = Moles*Molar mass = 0.0099 moles * 86.9368 g/mol = 0.86 g
Answer:
the motion is different.
Explanation:
the the motion is different because the particle in a book is solid particles and solid are packed together so so they can't move freely but while the the particles in the air around it is gas particles and it are packed very loose and can move very easily anywhere like .Example - solid-book , eraser. gas-helium, oxygen.
