Answer:
The answer to your question is: Molarity = 0.078
Explanation:
Data
HCl
V = 250 ml
T = 27°C = 300 °K
P = 141 mmHg = 0.185 atm
V2 = 70 ml
NaOH
V = 24.3 ml
Molarity NaOH = ?
Process
1.- Calculate the number of moles of HCl
PV = nRT
n = PV / RT
R = 0.082 atm l / mol K
n = (0.185)(0.25) / (0.082)(300)
n = 0.046 / 24.6
n = 0.0019 moles
2.- Calculate molarity of HCl
Molarity = moles / volume
Molarity = 0.0019 / 0.070
Molarity = 0.027
3.- Write the balanced equation
HCl + NaOH ⇒ H₂O + NaCl
Here, we observe that the proportion HCl to NaOH is 1:1 .
Then 0.0019 moles of HCl reacts with 0.0019 moles of NaOH.
4.- Calculate the molarity of NaOH.
Molarity = 0.0019 / 0.0243
Molarity = 0.078
Majority can such as hydrogen H and oxygen O forming water H2O but uranium having extra neutrons to form plutonium and beyond simply can't because it will not last for a fraction of a second or spiral out of control and violently react like the little boy and the fat man (a uranium and plutonium nuclear weapon) so yes and no
Answer:
potassium (K) and bromine (Br)
Explanation:
- Periodic table is a table of elements in terms of rows and columns in terms of their chemical and physical properties.
- Elements in the same group or columns have similar physical and chemical properties. For example, elements in the same group have the same number of valence electrons or valency.
- Elements in the same period or rows have similar number of energy levels. For example, potassium and bromine belong to the same period in the periodic table and thus have the same number of energy levels.
<span>Bodies of magma rise in the crust until they reach a point of neutral buoyancy. The expansion of gases brings the magma closer to the surface and drives eruptions. When more gases are dissolve into the magma, there would more chances of explosion. Hope this answers the question.</span>
