Isotopes of the same element have the same number of protons. Isotopes of the same element have the same number of neutrons. Isotopes are identified by their mass number.
Balanced chemical reaction of hydrochloric acid and barium sulfite:
2HCl(aq) + BaSO₃(s) → BaCl₂(aq) + H₂O(l) + SO₂(g).
Balanced ionic reaction:
2H⁺(aq) + 2Cl⁻(aq) + BaSO₄(s) → Ba²⁺(aq) + 2Cl⁻(aq) + H₂O(l) + SO₂(g).
Net ionic reaction:
2H⁺(aq) + BaSO₄(s) → Ba²⁺(aq) + H₂O(l) + SO₂(g).
Answer: Avogrado's Constant
Explanation:
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.
Answer:Earthquakes can strike at any location on Earth and at any point of time. However, some parts of the Earth are more prone to earthquakes than others. Earthquakes happen along the edges of tectonic plates and fault lines and there are three large zones on our planet which are most susceptible to earthquakes.
Explanation:
Answer:
The answer to your question is V2 = 867.3 mL
Explanation:
Data
Volume 1 = V1 = 400 ml
Temperature 1 = T1 = 22°C
Pressure 1 = P1 = 760 mmHg
Volume 2 = V2 = ?
Temperature 2 = T2 = 30°C
Pressure 2 = P2 = 360 mmHg
Process
1.- Convert Celsius to Kelvin
T1 = 22 + 273 = 295°K
T2 = 30 + 273 = 303°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
- Solve for V2
V2 = P1V1T2 / T1P2
- Substitution
V2 = (760 x 400 x 303) / (295 x 360)
- Simplification
V2 = 92112000 / 106200
-Result
V2 = 867.3 mL
