Help me!!! Several small craters lie in the floor and on the walls of crater 2. Which is older,crater 2 or the smaller craters i
Zinaida [17]
Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)

a volumetric pipette haas an uncertainty of 0.01 cm what are the lowest and highest possible volumes for a measurement of 0.20cm
Vanyuwa [196]

Answer:

Possible lowest volume = 0.19 cm

Possible highest volume = 0.21 cm

Explanation:

Given Data

uncertainty  =  0.01 cm

total volume = 0.20 cm

Possible lowest volume = ?

Possible highest volume =  ?

Solution:

Possible lowest volume = total volume - uncertainty

Possible lowest volume = 0.20 cm - 0.01 cm

Possible lowest volume = 0.19 cm

Possible highest volume = total volume + uncertainty

Possible highest volume = 0.20 cm - 0.01 cm

Possible highest volume = 0.21 cm

Two reactions and their equilibrium constants are given. A + 2 B − ⇀ ↽ − 2 C K 1 = 2.79 2 C − ⇀ ↽ − D K 2 = 0.186 Calculate the
vfiekz [6]

Answer:

K=1.93

Explanation:

Given reactions are:

A +2B ⇄ 2C  K1=2.79

2C ⇄ D K2=0.186

D⇄ A+ 2B K=?

If we reverse the reaction then the euillibrium constant also become reciprocal of original value:

3rd reaction is a combination of reciprocal of 1st and 2nd reaction

2C⇄A +2B   1/K1;........................1

D ⇄ 2C  1/K2; ..............................2

On adding 1 and 2

D ⇄A +2B    K=\frac{1}{K1} \times\frac{1}{K2};

K=\frac{1}{2.79} \times\frac{1}{0.186};

K=1.93
