Explanation:

Normal Earth temperature means the standard temperature and pressure conditions. At STP, temperature is 273 K or zero degree celsius and pressure is 1 atm.

For gases at STP, volume is equal to 22.4 liter.

So, at normal Earth temperature sodium exists as a solid whereas oxygen exists as a gas.

On the other hand, both bromine and mercury exists as liquid at normal Earth temperature.

Which bond is formed when a fatty acid is attached to a glycerol<br> molecule?<br> 2 of 8 QU
Mekhanik [1.2K]

Answer: Heyo Kenji Here! Here's your answer- In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.

Explanation: Hope this helps!

Have a nice day!

Identify the missing coefficient in the balanced equation and classify the type of reaction.
Lostsunrise [7]

Answer:

Option 6 ) Neutralization

Explanation:

For this case, the missing coefficient would be a "6" before the H₂O, within final products (right side of the equiation), hence, the final reaction should be:

2H₃PO₄ + 3Ba(OH)₂ ------> Ba₃(PO₄)₂ + 6H₂O

You should have in mind that the amount of atoms at each side of the chemical equation should be the same, so as to comply with the principle of mass conservation. If you add "6" on the left side of the H₂O, the equation will be balanced (for each side, lef and right, you will have: 12H, 2P, 14O and 3Ba)

Lastly, this is a chemical neutralization reaction, where an acid (H₃PO₄) is reacting with a base (Ba(OH)₂) in order to finally obtain a neutral salt (Ba₃(PO₄)₂) and water (H₂O)

Suppose the mass of a jelly bean is less than the mass of a gum drop. If you counted out 10 of each kind of candy and measured t
MAVERICK [17]

Answer: Option (a) is the correct answer.

Explanation:

Since it is given that the mass of a jelly bean is less than the mass of a gum drop.

So, when we counted out 10 of each kind of candy and measured the mass of each kind of candy, the mass of the jellybeans would be less than the mass of the gumdrops.

This is because mass of jelly bean is less and even if we take take or more jelly beans then also their total mass will remain less than the total mass of same number of gum drops.
