Answer:
Molarity of solution = 0.727M
Explanation:
Molarity of solution is defined as moles solute per Liter of solution. For the posted problem use M = n/V where n = moles of solute and V = Liters of solution. That is ...
n = 58.9g/180.16g·mole⁻¹ = 0.327 mole (3 sig. figs.)
V = 450.0ml/1000ml·L⁻¹ = 0.450L (3 sig. figs.)
∴ Molarity = n/V = 0.327mole/0.450L = 0.727mol/L = 0.727M
Answer:
Water
Explanation:
Water molecules are known to have a melting point of 0°C and a boiling point of 100°C.
The melting and boiling points are as a result of the intermolecular force of attraction between the molecules of water. The predominant bond type that dictates the property of the melting and boiling point is the hydrogen bonding. This bond is a strong force of attraction and it impacts on the physical properties of water.
I believe the correct response would be A. The cumulative nature of science. How experimental evidence and ideas made by many scientists have accumulated and or built up to have a more understandable and or clear view of a particular scientific topic, and or principle.
Answer:
First, balance the half-reactions
Second, equalize the electrons
Third,add two reaction equations to get final answer
Explanation:
For example
H₂C₂0₄ + MnO⁻₄ ---------->CO₂+Mn²⁺
(i) Balancing the half reactions
H₂C₂O₄-------->2CO₂+2H⁺+2e⁻
5e⁻ +8H⁺+MnO₄⁻----------->Mn²⁺+4H₂O
(ii)
Equalizing the electrons
5H₂C₂O₄--------->10CO₂+10H⁺+10e⁻ ---here there is a factor of 5
10e⁻+16H⁺+2MnO₄⁻--------->2Mn²⁺+8H₂O -----here there is a factor of 2
(iii)
Add the two where electrons and some Hydrogen ions will cancel out
5H₂C₂O₄+6H⁺+2MnO₄⁻---->10CO₂+2Mn²⁺+8H₂O
Noble Gases is the answer (please give me brainliest
