Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>
<em />
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
<h3>El volumen final del sistema es 1.2L</h3>
Answer:
4.5 × 10^14 Hz
Explanation:
According to this question, chlorophyll pigment strongly absorbs light with a wavelength of 662nm. To calculate the frequency of this light, the following formula is used:
λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3×10^8m/s)
f = frequency of light (Hz)
Since the λ = 662nm = 662 × 10^-9m,
f = v/λ
f = 3 × 10^8/662 × 10^-9
f = 0.004531 × 10^(8+9)
f = 0.0045 × 10^17
f = 4.5 × 10^14 Hz

Explanation:
B. 1) Tritium is the isotope of <u>Hydrogen</u><u> </u><u>(</u><u>H)</u><u>.</u>
2) Mass of an Electron is <u>9.10938356 × 10-³¹ </u> Kg.
3) Molecular mass of Carbon dioxide (CO2)
=><u> Molecular mass of carbon = 12g</u>
<u>Molecular mass of oxygen= 16g</u>
<u>molecular mass of CO2 = [12 + (16 X 2)]g</u>
= <u>(12 + 32)g</u>
= <u>44 g</u>
4) Dalton has given its Atomic Theory in the year <u>1803.</u>
5) Nucleus is discovered by
