Answer:

The correct answer is 2.33g of H_{2}O, A

Explanation:

We can use basic stoich to get this question.

To start, lets convert our grams to moles in order to use our equation. 5.38g of O_{2} = (\frac{5.38}{2*15.999}) moles = 0.168136 moles.

We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of O_{2} to moles of H_{2}O. This gets us 0.129335 moles of H_{2}O.

Now lets convert to grams of H_{2}O by multiplying by the molar mass of H_{2}O. .129335*(1.008*2+15.999) = 2.32997g of H_{2}O

What is T2, if T1= 500 k, v1=10L, V2=8L,P1=600 torr,P2=200 torr?
Molodets [167]

Answer:

T2 = 133.333°K

Explanation:

Using Combined Gas Laws:

(600 torr)(10L)/500°K = (200 torr)(8L)/x°K

\frac{600 torr(10L)}{500K} =\frac{200 torr(8L)}{xK}

Cross multiply:

x°K (600 torr)(10L) = 500°K(200 torr)(8L)

Divide:

x°K = (500°K(200 torr)(8L))/(600 torr)(10L)

xK = \frac{500K(200 torr)(8L)}{600 torr(10L)}

x = 400/3°K or 133.333°K

When 10.8 g of Silver was reacted with Sulfur, 12.4 grams of product was produced (there was only one product). What is the empi
alexandr1967 [171]

Answer:

Ag2S

Explanation:

10.8 gm of silver, 12.4 gm of silver sulfide, so 12.4 -10.8 = 1,6 gm of sulfur

silver atomic weight is 108, sulfur atomic weight is 32  so

10.8/108;   = 0.10 mole Ag  1.6/32 = 0.05 mole sulfur

so there is a 2:1 ratio of silver to sulfur, so the compound is 2 silver 1 sulfur or Ag2S
