The passage refers to solutions as homogeneous mixtures. what is the best definition of a homogeneous mixture?

1 answer:

3 0

The answer would be: <span>a.a mixture that is uniform throughout

A homogenous mixture would be hardly distinguishable since the solute spread evenly inside the solvent. A heterogeneous mixture is not spread evenly so it is </span>easily distinguishable.A suspension has a big molecule solute that will slowly settle and make sediment at the base of the solution. A colloid mixture is suspended but it won't settle like suspension does.

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 of $HOC(CO_2H)(CH_2CO_2H)_2$ . 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.

Determine the percentage composition of Ptl2

Hitman42 [59]

Answer:

Percent Composition

1. Find the molar mass of all the elements in the compound in grams per mole.

2. Find the molecular mass of the entire compound.

3. Divide the component's molar mass by the entire molecular mass.

4. You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

What is missing from the temperature and volume graph shown at right?

Kaylis [27]

Answer: Three things are missing:

i) Graph title.

ii) Label for the vertical axis.

iii) The scale and the units for the horizontal axis.

Justification:

1) Find the graph in the image attached.

2) What does the graph represent? You cannot tell because it does not show the tittle.

Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:

Temperature vs. Volume.

3) The vertical axis also must be properly labeled, including the units.

A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.

4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)
