Answer:
Antibacterial specifically refers to an inhibition of growth of bacteria, whereas antibiotics refer to a general inhibition of growth of microorganisms, which could include bacteria and viruses.
Answer:
the most common is 'direct combustion'.
Answer:
the discovery of atomic structure.
Explanation:
Rutherford was a famous scientist who gave his theory of atomic structure.
Ernest Rutherford was a great physicist who is well known for his pioneering studies and discoveries about atoms and radioactivity. Rutherford was considered to be the greatest experimentalist after Michael Faraday.
Rutherford's atomic model was one of the greatest discoveries which provided many answers and solutions to the structure of atom and molecules that our earth is surrounded of.
Rutheford discovered that an atom has a tiny mass of positively charged particles in the centre of the atom called nucleus and negatively charged electrons surrounds the nucleus.
Bohr joined Rutherford in his studies and discovered many new facts about the structure of the atom based on the Rutherford's model. Today atomic model is the product of Rutherford atomic structure.
<h3>
Answer:</h3>
3.072 L
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial pressure, P₁ = 345 torr
- Initial temperature,T₁ = -15°C
But, K = °C + 273
= -15°C + 273
= 258 K
- Initial volume, V₁ =3.48 L
- Final pressure, P₂ = 468 torr
- Final temperature, T₂ = 36°C
= 36 °C + 273
= 309 K
We are required to calculate the new volume, V₂
- Using the combined gas law;
P₁V₁/T₁ = P₂V₂/T₂
- We can calculate the new volume, V₂;
- Rearranging the formula;
V₂ =(P₁V₁T₂) ÷ (T₁P₂)
= (345 torr × 3.48 L × 309 K) ÷ (258 K × 468 torr)
= 3.072 L
Therefore, the new volume of the sample is 3.072 L
Answer:
Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
