goes on to the circle
Explanation:
hm and the I have know what how much you have want
Hey there!
Density = 2.67 g/cm³
volume = 30.5 mL
Mass = density *volume
Mass = 2.67 * 30.5
Mass = 81.435 g
Therefore:
Mass in kg :
1 kg -------------- 1000 g
?? ----------------- 81.435 g
mass = 81.435 * 1 / 1000
mass = 0.081435 kg
Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Answer:
Explanation:
Given that,
The volume of a sample of gas measured at 27 °C is 10.0 dm.
We need to find the temperature when the volume is reduced to 9.0 dm at the same pressure.
According Charles law,
Where, T₂ is new temperature
So, the new temperature is 
.
