Answer:

I believe that it is the 2nd option.

Explanation:

My reasonings are because C4H10O has 7 isomers. In which 4 are alcohol and the other 3 are ether.

The first option is ethers, specifically ethoxyethane.

The third option is ethers, specifically 1-methoxypropane.

The fourth option is an alcohol, specifically 1- butanol.

Therefore, leads us to the 2nd option that it is NOT an isomer of C4H10O

How many atoms are in the formula (NH4)2CO3? Please help and provide explanation!

nevsk [136]

Answer:

Explanation:

28 is correct. (NH4)2 is equal to 10 atoms. (8 H and 2 N ) CO3 is equal to 4 atoms. (1 C and 3 O) That's 14 atoms. But it's two molecules of this. So you just multiply by the number of molecules (2), and you get 28.

A weight of 22.25g was obtained when 10-mL of water at 27C was pipet to empty Erlenmeyer flask. What is the volume delivered by

Nimfa-mama [501]

Answer:

the volume delivered by the pipette = 22.32 mL

Explanation:

To calculate this, let us first note that the density of water relates it weight and its volume (density = mass ÷ volume), hence we are going to use density to determine the volume.

Density of water = mass/volume = 0.997 g/ mL

mass = 22.25g

Density = 0.997g/mL

volume = ?

$density = \frac{mass}{volume}\\\therefore volume = \frac{mass}{density}\\volume = \frac{22.25}{0.997}\\volume = 22.32\ mL$

∴ the volume delivered by the pipette = 22.32 mL

<em>Please note that this calculation is based on the fact that the weight of the empty flask has been determined and canceled out.</em>
