What is the main differences between boiling and evaporation

1 answer:

8 0

Answer:Los términos evaporación o vaporización se aplican al paso del estado líquido al estado gaseoso. Cuando el fenómeno se produce únicamente en la superficie de la masa líquida se designa como evaporación. Si el paso a vapor tiene lugar afectando toda la masa líquida se denomina vaporización o ebullición.

Solve for ‘x’: 12(x-7)+3(2x+2)=50x-2

Alex Ar [27]

Answer:

Explanation:

Hi there!

12(x-7) = 12x -84

3(2x+2) = 6x+6

Total 18x-78

18x-78 = 50x-2

-78= 32x-2

-76= 32x

19/8 =x

The density of liquid mercury is 13.5 g/cm^3. What mass of mercury (in kg) is required to fill a hollow cylinder having an inner

olya-2409 [2.1K]

Answer: 1.06 kg

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given :

Density of mercury = $13.5g/cm^3$

volume of cylinder = volume of mercury = $\pir^2h$

where r = radius of cylinder = $\frac{diameter}{2}=\frac{2cm}{2}=1cm$

h= height = 25.0 cm

Putting in the values we get:

volume of mercury = $3.14\times 1^2\times 25=78.5cm^3$

$mass=density\times volume=13.5g/cm^3\times 78.5cm^3=1059.75g=1.06kg$ (1kg=1000g)

Thus mass of mercury required to fill a hollow cylinder having an inner diameter of 2.00 cm to a height of 25.0 cm is 1.06 kg.

The substitution product that is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.

<h3>What is a substitution product?</h3>

A substitution product is a product that is gotten from a reaction in which a group of reactants is replaced by another group in the reaction.

Therefore, the substitution product is supposed to be favoured. The product with retention of configuration is expected to predominate slightly because the leaving group blocks the nucleophile.
