Using the formula PV=nRT (p is pressure of gas, v is volume of gas, n is amount of particles, r is the gas constant and t is absolute temperature of the gas), an increase in number of particles will result to an increase in pressure as long as the other variables remain constant.
Answer:
The source of the hydrogen is coming towards us.
Explanation:
The wavelength of the hydrogen is decreasing as it goes from 486.1 nm to 486.0 nm.
<u>The wavelength of a wave is directly proportional to the distance between the observer and the object.</u>
For example, when the observer is far from the source, the observer will observe a longer wavelength which corresponds to red color if it is in the visible region.
<u>As the wavelength is decreasing that means that the hydrogen particle ( source may be a star) is coming towards the observer.</u>
Thus, we can conclude that the source of the hydrogen is coming towards us.
Answer:
296.33K
Explanation:
Data;
Q = 852J
mass (m) = 38.4g
θ₂ = 32.5°C = 305.5K
θ₁ = ?
c = 2.42 J/g.K
From the equation of heat transfer;
Heat transfer (Q) = MC∇θ
Q = mc(θ₂ - θ₁)
852 = 38.4 * 2.42 * ( 305.5 - θ₁ )
852 = 28389.504 - 92.928θ₁
Collect like-terms
92.928θ₁ = 27537.504
Divide both sides by 92.928 to make θ₁ the subject of formula .
θ₁ = 296.33K
... in neutralization reactions, for example:
NaOH + HCl = NaCl + H₂O
2KOH + H₂SO₄ = K₂SO₄ + 2H₂O
