Answer:
B. cloud formation
Explanation:
The event that will most likely occur is cloud formation. This is because Rising Air is the key process in the production of clouds and precipitation. This occurs because the air rises and as it rises it begins to expand, it expands so much so that the temperature of the air begins to decrease and humidity rises until cloud droplets begin forming as the excess water vapor condenses on the the air particles.
Answer:
The answer is
<h2>110.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of rock = 5.8 g/mL
volume = final volume of water - initial volume of water
volume = 12.4 - 10.5 = 1.9 mL
The mass of the rock is
mass = 5.8 × 1.9
We have the final answer as
<h3>110.2 g</h3>
Hope this helps you
Mass of methane takne = 1.5g
moles of methane used = masss / molar mass = 1.5 / 16 = 0.094 moles
mass of water = 1000 g
Initial temperature of water = 25 C
final temperature = 37 C
specific heat of water = 4.184 J /g C
1) Heat absorbed by water = q =m• C• ΔT = 1000 X 4.184 x (37-25) = 50208 Joules
2) Heat absorbed by calorimeter = Heat capacity X ΔT = 695 X (37-25) = 8340 J
3) Total heat of combustion = heat absorbed by water + calorimeter = 50208 + 8340 = 58548 Joules
This heat is released by 0.094 moles of methane
So heat released by one mole of methane =
- 622851.06 Joules = 622.85 kJ / mole
4) standard enthalpy of combustion = -882 kJ / mole
Error = (882-622.85) X 100 / 882 = 24.84 %
The enol carbon or ∝-carbon nucleophile attacks at molecular bromine in the acid-catalyzed α-bromination of a ketone
Treatment of ketones with bromine in the presence of acid will results in formation of a new C-Br bond at the alpha position. The purpose of the acid is to catalysed formation of the enol from ketone , which is active nucleophile in the reaction. This reaction is called haloform reaction which is used to identify the methyl substituted ketone in the presence of aldehyde.
