Citric acid (right) is concentrated in citrus fruits and plays a central metabolic role in nearly every animal and plant cell.
arlik [135]

<u>0.549 mol</u> of citric acid are in 1.50 qt of lemon juice (d = 1.09 g/mL) that is 6.82% citric acid.

<h3>What is citric acid?</h3>

Citric acid is an organic compound with a chemical formula ofHOC(CO_2H)(CH_2CO_2H)_2 . It is a weak organic acid that is colourless. Citrus fruits naturally produce it. It is a biochemical intermediary in the citric acid cycle, which is a process that all aerobic organisms go through during metabolism.

Every year, more than two million tonnes of citric acid are produced. It is frequently employed as a chelating agent, an acidifier, and a flavouring

Citrates, which include salts, esters, and the polyatomic anion present in solution, are derivatives of citric acid. Trisodium citrate is an example of the former; triethyl citrate is an example of an ester.

What is the volume of 3.00 mole of ideal gas at 100.0 C and 2.00 kPa
Novosadov [1.4K]

Answer:

The volume for the ideal gas is: 4647.5 Liters

Explanation:

Formula for the Ideal Gases Law must be applied to solve this question:

P . V = n .  R . T

We convert the T° to K → 100°C + 273 = 373 K

We convert pressure value from kPa to atm.

2 kPa . 1atm/101.3 kPa = 0.0197 atm

We replace data in the formula.

V = ( n . R . T) / P → (3 mol . 0.082 . 373K) / 0.0197 atm =

The volume for the ideal gas is: 4647.5 Liters

What best describes the conditions to becoming a fossil
Ede4ka [16]
Hello

I don't quite understand the question your asking and if there is any answers provided but I will still give you mine.


Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.


Hope this helps!!

Would carbon dioxide or water have a higher boiling point? Explain.
oee [108]

Answer:

Water acutually has a higher boiling point because CO2 will turn into a gas form at a certain temp ( -78 C), so CO2 wouldn't really boil very long.

Hope this helps:)
