Answer:
There's billions of people on this planet I doubt you are alone.
Ice is a solid. Water is a liquid. Water vapor is a gas.
In the reaction, Na⁺ + 6H₂O ⇆ Na (H₂O)⁺₆, Na⁺ is a Lewis acid and H₂O is a Lewis base.
<h3>
What is a Lewis acid-base reaction?</h3>
- According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
- Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
- Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
- Here Na⁺ that is electron deficient accepts electrons from the electron donor, H₂O
- From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.

Answer:
0.8 moles
Explanation:
2H2+O2 —›2H2O
Since , from given balanced chemical Equation.
2moles of H2 produce 2 moles of Water
So,
2moles H2= 2moles H2O
1moles H2= 1 mole of H2O
For 0.8 mole of H2O, multiply both sides by 0.8
0.8 H2=0.8 H2O
0.8 mole of H2= 0.8 mole H2O
So answer is 0.8 moles
Answer:
The correct answer is option C.
Explanation:
r = resultant vector
y = vertical component of vector
x = horizontal component of vector
We have :
The vertical component of a vector is 40 N and its horizontal component is 25 N.
x = 25 N
y = 40 N
47.2 N is the magnitude of the vector.
