They both have stages where they are born and die.
Answer:
feel slippery
Explanation:
they feel slippery in the hands when touched
In a chemical reaction equation.. There must be redox reaction taking palce.. So oxidation and reduction reactions will be happening on both sides of the equation.. You can separate the oxidation and reduction equations in halves. . So there will be one half oxidation equation and the other half reduction equation of the reaction.
Answer:
0.643 mol.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm (P = 4.0 atm).
V is the volume of the gas in L (V = 4000 mL = 4.0 L).
n is the no. of moles of the gas in mol (n = ??? mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 30ºC + 273 = 303 K).
<em>∴ n = PV/RT </em>= (4.0 atm)(4.0 L)/(0.0821 L.atm/mol.K)(303 K) = <em>0.643 mol.</em>
