Answer: Oxygen 17 is an isotope of Oxygen 16.
Explanation: An isotope is an element with more or less neutrons, and the 16 and 17 represent the mass of the oxygen molecule. So oxygen 17 has one more neutron than oxygen 16.
Answer:
the answer to your question is Metallic character increases, and electronegativity decreases.
Explanation:
Substance x is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature, is mathematically given as
Q=800J.mol^{-1}
<h3>What is a graph of the other properties of x?</h3>
Generally, the equation for heat absorbed is mathematically given as
Q= Heat capacity of solid *T
In conclusion,
Q= (40)(293.15-273.15)
Q=800J.mol^{-1}
In conclusion, Because the enthalpy of fusion is 9 KJmol-1 and we are only providing 6 KJmol-1 of heat, the melting process will not be complete. the graph is attached.

Salt and water is a homogeneous mixture. Sand and water,salad dressing,soil are heterogeneous mixtures.
The frequency of the photon of light is 4.4 * 10¹⁶ Hz
<h3>Energy and frequency of light</h3>
- The energy and frequency of light are related by the formula given below:
- E = hf
Where h is Planck's constant = 6.626 * 10⁻³⁴
f is frequency
E = energy
making f subject of the formula
f = E/h
f = 2.95 × 10⁻¹⁷/6.626 * 10⁻³⁴
f = 4.4 * 10¹⁶ Hz
Therefore, the frequency of the photon of light is 4.4 * 10¹⁶ Hz
