Answer:
BCI3 is a non polar compound because there is no neutral in it
Answer:
magnesium= +2
aluminum= +3
phosphorous= -3
lithium= +1
fluorine= -1
Explanation:
As fluorine having seven valance electrons in its outer most shell with atomic number nine. And for completing its outer most shell it needs one more electron that is why it form ion of -1 value.
Now Aluminum has three electrons in its outer most shell with atomic number 13. So it need to lose these three electrons in order to be in stable state that is why it have ion in +3 state.
Same rule apply for other elements too.
Answer:iron and carbon
Explanation:I took the test it’s iron and carbon
<u>Answer:</u> The temperature will be 1501.47 K.
<u>Explanation:</u>
To calculate the temperature of the gas when pressure is increased, we use the equation given by Gay-Lussac's Law.
This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
Mathematically,
or,
where,
are the initial pressure and initial temperature of the gas.
are the final pressure and final temperature of the gas.
We are given:
Putting values in above equation, we get:
Hence, the temperature will be 1501.47 K
Earth's core and the geodynamo. The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.
