Answer:about 10,000 years b maybe

Explanation:Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure.

It can stay radioactive from 1,000 to 10,000 years. I honestly don’t know which answer to choose but it’s going to be between those two.

Write the formula equation for the reaction between hydroiodic acid and beryllium hydroxide
Aleksandr-060686 [28]
 The  formula  equation for  the reaction  between  hydroiodic  acid  and  beryllium  hydroxide      is as below

Be(OH)2  +  2 HI   =  BeI2 +   2H2O


Formula  of  hydroiodic is  =  HI
formula   of  beryllium hydroxide = Be(OH)2


1 mole  of  Be(OH)2  react  with   2  mole  of HI to form  1 mole  of BeI2  and   2   mole  of H2O

So you are using the combined gas law
shusha [124]

Answer:

7.22L

Explanation:

At Stp T2 = 273K and P2 is 1 atm

So we have the following data

V1 =10L. P1=650mmHg(0.855atm)

V2 =V2. P2 = 1 atm

T1=50°c (323K) T2 =273K

Hence from the combined gas law

P1xV1 /T1 =P2xV2/T2

0.855x10/323 =1xV2 /273

8.55/323 =V2 /273

V2 = 8.55x273 /323

V2 = 7.226 L
