I hope this helps you :)
Answer:
The presion is 0.6 atm
Explanation:
P1V1=P2V2
P2 = P1V1/V2
P2 = (4.00 atm * 0.30 L) / 2.0 L
P2= 0.6 atm
Explanation:
Iron atom is been oxidised as it losses 2 electron to form 2 + ion.
Answer:
Calcium chloride (CaCl2) would help me eat my ice cream faster
Explanation:
Addition of salt to ice melts the lowers the freezing temperature of the ice thus melting the ice easily
Adding calcium chloride to my ice cream would help me eat it faster because the melting point of calcium chloride (772°C) is lower than that of sodium chloride (melting point is 801°C). Calcium chloride would melt my ice cream faster because of its lower melting point
