Explanation:
The word that best fits the underlined in the sentence is "free-to-rotate." The carbon atoms in their carbon bonds are free to rotate since alkanes do not have geometric isomers. They only have single bonds and the most common example of which are trans molecules.
An element cannot be broken down any further. Elements can be found on the periodic table
Acceleration is the rate at which an object changes its speed. When a raindrop is falling down from the clouds due to gravity, the veloicty is pretty much fast, however air resistance comes in action and slows the droplet down... it gives it a constant speed until it hits the ground
The correct answer is + 32.5 J because heat is absorbed here by copper not evolved also after calculation we will find the H value is positive, lets calculate it:
H = m C Δt where:
m = 10 g
C = 0.13 J/g.°C
Δ t = final temperature - initial temperature = 50 - 25 = + 25 °C
so H = 10 x 0.13 x (+25) = + 32.5 J
