Answer:

In effusion, a substance escapes through a tiny pinhole, or other hole whereas diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

Explanation:

According to effusion, if there is a small hole in a container, a gas will leak from it. So, in this process a substance escapes through a tiny pinhole, or other hole.

According to diffusion, the two solutions will reach the lowest possible concentration of both, if they are combined and not mixed. So, diffusion is the spreading out of a substance within a dispersing medium.

Effusion and diffusion are similar in terms of rates and speeds.

NiB13 + Al2S3>? What is the product you get from these 2 reactants. It’s a double replacement equation.

fgiga [73]

Answer:

NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃

Explanation:

A double replacement reaction is a reaction in which the cations switch anions.

In the reaction, the two cations are Al and Ni. The cations are Br and S.

Put each cation with the opposite anion: Ni with S and Al with Br.

The products would be NiS₃ and Al₂Br₃.

The full reaction is NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃.

Hope that helps.

Daniel needed 5.0 x 10 3mm of copper wire for his senior year science project. When Daniel went to the hardware store, he notice

blondinia [14]

Answer:

if its 5X 10^3 mm=5m and if its 5X 10^-3 mm=5X 10^-6m

Explanation:

we know,

1m= 1000mm

as given 5X 10^3 mm we have to convert to meter

now 5X 10^3 mm= 5X 10^3/1000=5m

but if its 5X 10^-3 mm= 5X 10^-3/1000= 5X 10^-6m

thank u,
