C. released or absorbed.

When the energy is released the reaction is called exotermic reaction
When the energy is absorbed, the reaction is called endothermic reaction

An example of exotermic reaction is between water and H2SO4

Natalija [7]

Answer:

625=275

240=x

625x=275×240

625x=66000

x=66000/625

x=105 .6

Explanation:

If 625°C gives us 275KPa then 240°C will give us the the sum of 275×240 divided by 625

The ksp of lead(ii) carbonate, pbco3, is 7.40 × 10-14. calculate the solubility of this compound in g/l.
Dennis_Churaev [7]
The  molar  solubility  is  the  Pb ions  present. PbCO3  dissociate  to  form  Pb  ions  and CO3  ions
Ksp  7.40x10^-14 is equal to  (Pb  ions) (CO3 ions)
Pb ions  correspond  to  CO3  ions
(pb ions)( Pb ions) is  equal to 7.40x10^-14
therefore  Pb  ions is square  root  of 7.4x10^14 which  is 2.27x10^-7m
In  
g/l   is (2.27x10^-7) x 267(RFM  of PbCO3) which  is  6.06x10^-5 g/l

The compound IF5 contains Question 16 options: polar covalent bonds with partial negative charges on the F atoms. ionic bonds. p
larisa86 [58]

Answer:

See explanation

Explanation:

The molecule IF5 possesses five I-F polar bonds. However, the presence of polar bonds does not automatically imply that the molecule will be polar.

The geometry of the molecule is very important in determining the polarity of a compound. Since IF5 has a lone pair of electrons, the molecule is bent and as such there is a permanent dipole moment created in the molecule thereby making IF5 polar in nature.
