Answer:
I hope this helped
Explanation:
1. A region with a high probability of containing electrons. An example is a simple atom, like Hydrogen.
2. Bohr's model of the atom, in which electrons circle the nucleus at fixed energy levels, cannot explain all the behaviors of electrons. Orbitals are the basis of the electron cloud model of the atom.
The waves emitted from the microwave sends the molecules within the object into a faster motion. The heat is generated from the faster movement of the molecules in the object. ... It is only transformed into new substances or energies.
Answer:
<h2>59.1 m</h2>
Explanation:
The height of the object can be found by using the formula
where
p is the potential energy
m is the mass
h is the height
g is the acceleration due to gravity which is 10 m/s²
From the question we have
We have the final answer as
<h3>59.1 m</h3>

2. HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
<em>Step 1</em>. Write the <em>molecular equation
</em>
HF(aq) + KOH(aq) → KF(aq) + H_2O(ℓ)
<em>Step 2</em>. Write the <em>total ionic equation
</em>
HF and H_2O are <em>weak electrolytes</em>, so we write them as <em>molecules</em>.
HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)
