Answer:
Fácil, vas a la tabla periódica, y el número de protones, será el numero atómico, es decir, el que determina qué elemento es. Y para obtener el de electrones, deberás, restarle al numero másico el numero atómico, que es el número de protones y electrones en el elemento.
Explanation:
Gamma rays, or rather gamma radiation are most commonly used.
Answer:
10.08 L.
Explanation:
- If we assume that CO₂ gas behaves ideally at STP (standard T(0.0 °C) and P(1.0 atm)):
<em>It is known that 1.0 mole of ideal gas occupies 22.4 L at STP conditions.</em>
<em></em>
<u><em>Using cross multiplication:</em></u>
1.0 mole of CO₂ gas occupies → 22.4 L.
0.45 mole of CO₂ gas occupies → ??? L.
<em>∴ The volume occupied by 0.45 mole of CO₂ gas </em>= (0.45 mol)(22.4 L)/(1.0 mol) = <em>10.08 L.</em>
