Answer:
527.74 mL of oxygen gas should be produced under conditions of STP from a 1.52 grams sample of iron (III) perchlorate .
Explanation:
Volume of the oxygen gas under given conditions 
Pressure of the oxygen gas , 
(1 atm = 760 Torr)
Temperature of the gas of the oxygen gas ,
At STP. the pressure of the gas = 
At STP, the temperature of the gas= 
At STP. the volume of the oxygen gas = 
Using combined gas law to find out the volume of oxygen gas at STP:
527.74 mL of oxygen gas should be produced under conditions of STP from a 1.52 grams sample of iron (III) perchlorate .
No it can't. To be a molecular compound it should <span>contains at least two different elements. As it is made up of only gold (Au) atoms it violates the above requirement.</span>
C. Liquid. The Earth is mostly water, namely ocean water which is liquid.
The formula of heat added is presented as
Q = m * c * change in (T)
where
Q - the heat added
m - mass
c - specific heat
<span>Change in temperature</span> - (Tf - To)
Basically, in order for us to know the change in heat, the formula is
Change in temperature = T(final) - T(original)
Change in temperature<span> = 36.65 - 24.85
</span>Change in temperature<span> = 11.8 degrees Celcius
</span>
So the change in temperature is 11.8 degrees
Answer:
It is a chemical change.
Explanation:
When the electricity is off, the filament cools down to its original physical state. This physical process repeats every time the light is turned on and off. However, if the bulb is cracked and air is introduced, the oxygen in the air reacts with the tungsten filament which then undergoes a chemical change.
