D. The total number of valence electrons is 8 and D represents that. D also correctly uses the octet rule for N and duet rule for H.
Answer:
Explanation:
Hello!
In this case, according to the ideal gas equation ratio for two states:
Whereas both n and R are cancelled out as they don't change, we obtain:
Thus, by solving for the final pressure, we obtain:
Now, since initial conditions are 1.00 atm, 273.15 K and 17 L and final temperature and volume are 94 + 273 = 367 K and 12 L respectively, the resulting pressure turns out to be:
Best regards!
Tin is an element called Stannum and has the symbol Sn. Molar mass is the mass of 1 mol of a compound, 1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up an element or molecules making up a compound.
While the number of atoms making up 1 mol is the same for any element, the weight of 1 mol of substance varies from one another.
In tin(Sn) molar mass - 118.71 g/mol
In 118.71 g - there's 1 mol of tin
therefore in 37.6 g of tin - 1 x 37.6 / 118.71 = 0.31 mol
In 37.6 g of tin, there's 0.31 mol
