You have an unknown compound of Potassium derivatives (KIxOy). This sample contains 17.0g of potassium, and 27.8g of oxygen and

55.2g of iodine. If you prepared another sample, but this time it had 460.0g of potassium periodate, how much oxygen and iodine would you have in your sample?

Chlorine is more reactive than nitrogen why​
OLga [1]

But nitrogen is inert at room temperature whereas chlorine is highly reactive, the reason is: Nitrogen exists as N triple bond N at room temperature while chlorine exists as Cl single bond Cl at room temperature. Since the bond dissociation energy of triple bond is larger than that of single bond.

Do all rocks follow the same pathway through the rock cycle? Explain.
ivolga24 [154]
I would have to say no. There are metamorphic rocks, igneous rocks, and sedimentary rocks. Igneous rocks are rocks that have solidified from magma or lava upon cooling, like lava rocks. Sedimentary rocks are rocks from smaller sediments, such as sandstone being made from, well, sand. Metamorphic rocks are the result of preexisting rocks in a response to changes in the environment. This includes changes in pressure, air temperature, mechanical stress, as well as taking away or adding chemical components. Metamorphic can be from igneous, sedimentary, or any other metamorphic rocks. Hopefully this help (with the added bonus that I explained all three type of rocks.

A box contains a mixture of small copper spheres and small lead spheres. The total volume of both metals is measured by the disp
kirill115 [55]

Answer:44.01% of the spheres are copper

Explanation:

mass Cu + mass Pb = 4.35kg =  4.35 x 1000 = 4350g

But

Volume= mass / density

Let the volume of copper be C  

density of  Cu = 8.94 g/cm^3

Mass of copper = 8.94C

Let the volume of Lead be L  

density of  lead = 11.34g/cm^3

Mass of lead  = 11.34L

Since  

mass Cu + mass Pb = 4350kg

therefore

8.94C + 11.34L = 4350g----- EQN A

also

volume of copper + volume of lead =  423 cm^3

Volume of Lead ,L=423-C

putting the value of C = 423-L in Equation A becomes

8.94C + 11.34L = 4350g

8.94C + 11.34(423-C)= 4350g

8.94C+ 4796.82-11.34C=4350

4796.82-4350=11.34C- 8.94

446.82=2.4C

C= 186.175

Volume of copper = 186.175cm^3

Percentage copper = volume copper / total volume metal x 100/1

= 186.175 cm^3 / 423 cm^3 x 100/1

= 44.01%
