PV / T = P'V' / T'
V = V'
P / T = P' / T'
P = 630 mmHg
T = 100 K
P' = 1760 mmHg
T' = ?
630 / 100 = 1760 / T'
T' = 1760 / 6,3
T' = 279,36 K
T' ≈ 280 K
g - Measurement of Mass
m² - Measurement of Area
m³ - Measurement of Volume
km- Measurement of Length
It’s a synthesis reaction, which is when 2 or more substances react to form a single product.
I hope this helps
Answer:
E. All of the above are true.
Explanation:
<em>Which of the following statements is TRUE?</em>
<em>A. State functions do not depend on the path taken to arrive at a particular state.</em> TRUE. State functions like enthalpy (ΔH) and internal energy (ΔE) do not depend on the trajectory, but on the initial and final state.
<em>B. Energy is neither created nor destroyed, excluding nuclear reactions.</em> TRUE. Only in nuclear reactions can energy (E) can be transformed in matter (m) and vice-versa according to Einstein equation: E = m . c² (c is the speed of light).
<em>C. ΔHrx can be determined using constant pressure calorimetry.</em> TRUE. The enthalpy of reaction is the heat involved at constant pressure.
<em>D. ΔErx can be determined using constant volume calorimetry.</em> TRUE. The internal energy of reaction is the heat involved at constant volume.
The correct answer is:
a positron is emitted when proton converts to a neutron.
The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.
