One atom of silicon can properly be combined in a compound withtwo atoms of oxygen to produce silicon dioxide because silicon is very similar to carbon, as it is in the same group as carbon is in, therefore, it is able to make four bonds.
Moreover, Silicon has 4 valence electrons. In order to form an ionic bond, silicon<span> would have to gain or lose 4 electrons.</span>
The final temperature is 34.91°C
<u>Explanation:</u>
<u></u>
Initial volume, V1 = 362m³
Final volume, V2 = 632m³
Initial temperature, T1 = 20°C
Final temperature, T2 = ?
We know,
V1/T1 = V2/T2
362/20 = 632/T2
T2 = 34.91°C
Therefore, the final temperature is 34.91°C
Answer:
E=1.50\times 10^{-18}J
Explanation:
Energy of the one dimensional infinite well,

Given that, 
For the ground state n=1,
Therefore energy is,

Answer:
39.6138 °C
Explanation:
Heat gain by water = Heat lost by nickel
Thus,

Where, negative sign signifies heat loss
Or,

For water:
Volume = 100.0 mL
Density of water= 1 g/mL
So, mass of the water:
Mass of water = 100 g
Initial temperature = 22.0 °C
Specific heat of water = 4.186 J/g°C
For nickel:
Mass = 275 g
Initial temperature = 100 °C
Specific heat of nickel = 0.444 J/gK = 0.444 J/g°C
So,




Thus,
The final temperature of the combined metals is 39.6138 °C
