Why does water roll off of dry ice?

1 answer:

8 0

It's a combination of carbon dioxide gas from the dry ice, and tiny water droplets.) ... The dry ice fog is heavier (denser) than air, so it sinks down. But it's less dense than water, so it floats on the water. The bubbles are heavier than air, but less dense than carbon dioxide fog, so they'll float on the fog.

Calculate the molecular weight of a dibasic acid.0.56gm of which is required 250ml of N/20 sodium hydroxide solution for neutral

Alekssandra [29.7K]

<u>Answer: </u>The molecular weight of the dibasic acid is 89.6 g/mol

<u>Explanation:</u>

Normality is defined as the amount of solute expressed in the number of gram equivalents present per liter of solution. The units of normality are eq/L. The formula used to calculate normality:

$\text{Normality}=\frac{\text{Given mass of solute}\times 1000}{\text{Equivalent mass of solute}\times \text{Volume of solution (mL)}}$ ....(1)

We are given:

Normality of solution = $\frac{1}{20}=0.05N$

Given mass of solute = 0.56 g

Volume of solution = 250 mL

Putting values in equation 1, we get:

$0.05=\frac{0.56\times 1000}{\text{Equivalent mass of solute}\times 250}\\\\\text{Equivalent mass of solute}=\frac{0.56\times 1000}{0.05\times 250}=44.8g/eq$

Equivalent weight of an acid is calculated by using the equation:

$\text{Equivalent weight}=\frac{\text{Molar mass}}{\text{Basicity}}$ .....(2)

Equivalent weight of acid = 44.8 g/eq

Basicity of an acid = 2 eq/mol

Putting values in equation 2, we get:

$44.8g/eq=\frac{\text{Molar mass}}{2eq/mol}\\\\\text{Molar mass}=(44.8g/eq\times 2eq/mol)=89.6g/mol$

Hence, the molecular weight of the dibasic acid is 89.6 g/mol

a diagram of the electromagnetic spectrum is shown. which wavelength is the longest safest wavelengths for humans？ Helppp please

alexdok [17]

Answer:

radio waves

Explanation:

the answer is simple, radio waves. it is radio waves because when you look at the diagram the waves below Radio are very long. if you look at the waves under gamma ray, they are very short. radio is the longest wave while gamma is the shortest. if you are still confused it also says longer wavelength and low frequency( meaning it is safe) right under the wavelength.
