Nuclear fusion is the combination of two nuclei to form a heavier nucleus. Colliding hydrogen atoms to produce helium is a form of nuclear fusion.
Answer:
September 9 at 9pm, the following year
Explanation:
We are given from the question above that;
=> Theo observers a star at 9:00 P.M. on September 9.
Theo will be able to see the exact star at the same position and at the exact time of night again the following year. This is because the stars move at least one degree everyday. Thus, the star will move 360 degree in a year. So, Theo will be able to see the same star by September 9 at 9pm, the following year.
The answer with this question you could use the characteristic properties you could say it’s a liquid or the substance in the fluid state of matter having no fixed shape but a fixed volume the example would be water. Solid gas you can include melting point boiling point whether it’s an element or a pure substance.
Answer:
2Ag⁺ (aq) + 2OH⁻ (aq) → Ag₂O (s) + H₂O (l)
Explanation:
Step 1: RxN
2AgNO₃ + 2NaOH → Ag₂O + 2NaNO₃ + H₂O
Step 2: Define states of matter
2AgNO₃ (aq) + 2NaOH (aq) → Ag₂O (s) + 2NaNO₃ (aq) + H₂O (l)
Step 3: Total Ionic Equation
2Ag⁺ (aq) + 2NO₃⁻ (aq) + 2Na⁺ (aq) + 2OH⁻ (aq) → Ag₂O (s) + 2Na⁺ (aq) + 2NO₃⁻ (aq) + H₂O (l)
Step 4: Cancel out spectator ions
2Ag⁺ (aq) + 2OH⁻ (aq) → Ag₂O (s) + H₂O (l)
