Explanation:
cl2 = 50/71
mole of cl2 = 0.704
no.of molecules = mole × avagadro no.
no of molecules = 0.704× 6.022×10²³
no. of molecules = 4.23×10²³
Aye daddy
Lucky thing i just came back xD
Its 78.66 to the nearest sig fig
U can google it 2
Since it takes 4ever to type it out i wrote it intead srry if its messy lol
Salt and water is formed as product, when Arrhenius acid and Arrhenius base reacts and the reaction is known as neutralization reaction.
<h3>
What is Arrhenius acid-base reaction?</h3>
- The concept of acid and base based on the theory of ionization which was first proposed in 1884 by Svante Arrhenius
- According to Arrhenius, on dissociation in water the hydrogen-containing compounds which give H+ ions or protons are the acids and the hydroxide compounds which give OH− ions on dissociation in water are bases.
- This theory is applicable only to compounds which are dissolved in aqueous solution.

Answer:
The time required to melt the frost is 3.25 hours.
Explanation:
The time required to melt the frost dependes on the latent heat of the frost and the amount of heat it is transfered by convection to the air .
The heat transferred per unit area can be expressed as:

being hc the convective heat transfer coefficient (2 Wm^-2K^-1) and ΔT the difference of temperature (20-0=20 °C or K).

If we take 1 m^2 of ice, with 2 mm of thickness, we have this volume

The mass of the frost can be estimated as

Then, the amount of heat needed to melt this surface (1 m²) of frost is

The time needed to melt the frost can be calculated as
