Answer:
Mass number
Nucleus
Explanation:
The combined number of protons and neutrons is the mass number in atomic notation.
The atomic number is just the number of protons alone.
The nucleus holds both neutrons and protons.
Electrons circle around the nucleus.

Explanation:
Growing Peas
Planting depth should be roughly 2 inches with a spacing of about 2 inches apart. Water well at planting and provide at least 1 inch of water per week, particularly during the flowering and pod production stages. As the temperature rises, the vines may need to be deeply watered almost every day.
Make sure to moniter it and change the water depending on how dry or overwatered it looks like. :)
Answer:
3.6 × 10²⁴ atoms of O
Explanation:
Let's consider the molecular formula of silver nitrate: AgNO₃.
We can establish the following relations:
- 1 mol of AgNO₃ has 6.02 × 10²³ molecules of AgNO₃ (Avogadro's number).
- 1 molecule of AgNO₃ has 3 atoms of oxygen.
The atoms of oxygen in 2.0 moles of silver nitrate are:
We use concentration calculations. MgCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MgCl2 that dissolves.
MgCl2(s) --> Mg+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.64 mol MgCl2/1L × 2 mol Cl⁻ / 1 mol MgCl2 = 1.3 M
The answer to this question is [Cl⁻] = 1.3 M

Explanation:
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
Anaerobic respiration in plants produced ethanol which if accumulate then cause the harmful effect in plants. It is also occur in some microorganisms such as yeast.
C₆H₁₂O₆ → 2C₃H₆O₃
Anaerobic respiration in animals pyruvate converted into lactic acid and it is not as harmful as ethanol in plant if accumulate. It is produced during exercise. It can produce the cramps which can be cured with massage.
C₆H₁₂ + O₂ → CO₂ + H₂O
This reaction is the combustion reaction of cyclohexane. Cyclohexane burnt in the presence of oxygen and form water and carbon dioxide.
