Charles law gives the relationship between temperature of gas and volume of gas.
It states that for a fixed amount of gas, temperature is directly proportional to volume of gas.
V / T = k
where V- volume , T - temperature and k - constant
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
T1 = 250 °C + 273 = 523 K
T2 = 150 °C + 273 = 423 K
Substituting the values in the equation,
V = 251 mL
the new volume is 251 mL
Answer:
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
Answer:
Answer
Answer is option B coz da negative charge r more thn positive
2HCl (aq) + Zn²⁺ ⇒ ZnCl₂ + 2H⁺ Total Reaction
Leo goes Ger (Lose electron oxidize, Gain electron reduction)
Zn²⁺ + 2e⁻ ⇒ Zn Oxidation half-reaction
2H ⇒ 2H⁺ + 2e⁻ Reduction half-reaction
