SO2 + O2 ---> SO3. Moles of SO2 = 0.64/32+16X2 = 0.01mole. According to stoichiometry, moles of SO2 = moles of O2 = 0.01mol. Therefore volume of oxygen gas at STP = 22.4 x moles of O2 = 22.4 x 0.01 = 0.224 = 224mL.
Answer:
You kinda left out the atom being discussed.
But My guts tell me its Berrylium
Answer: "Beryllium – 10".
Organic Chemistry- Substances only found in living organisms.
Physical Chemistry- Structure of physical compounds and the amount of energy they have.
Inorganic Chemistry- Study of carbon containing compounds.
Using coupons seems like an old-fashioned, time-consuming way to save a few cents on the products you buy at the grocery store. After all, most coupons don't usually have a face value of more than $1 and, quite often, they're worth far less. But done properly, couponing can save you thousands of dollars every year.
Answer ; The correct answer is : 346 m/s .
Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .
Speed of sounds depends on factors like medium , density , temperature etc .
Effect of Temperature on speed of sounds :
When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .
The speed of sounds at 0⁰C is 331 
The relation between speed of sound and temperature is given as :

Given : Temperature = 25 ⁰ C
Plugging values in formula =>
