Is sponge cake a heterogeneous mixture

Chemistry
1 answer:
maxonik [38]3 years ago
5 0

Answer:

though many may argue that cake batter is a homogeneous mixture because of its observable uniformity, we know it is heterogeneous. ... In other words, the mixture of ingredients from cake batter results in some chemical reactions here and there, but we are still left with a mixture of things that can be separated.

Answer:

<h3>Which of the following increases with the increase in the temperature in case of a liquid?</h3><h2><em>Va</em><em>pour</em><em> </em><em> </em><em>Pressure</em><em> </em></h2>

Explanation:

When a closed container contains liquid, higher the temperature, higher the evaporation the evaporation will be.

So Vapour Pressure should be the correct answer.

What enzyme catalyses the reaction of PRPP transfer to hypoxanthine with<br> formation of IMP?
Alona [7]

Answer:

HPRT

Explanation:

HPRT catalyzes the salvage reactions of hypoxanthine and guanine with PRPP to form IMP and GMP

The formation of GMP from IMP requires oxidation at C-2 of the purine ring, followed by a glutamine-dependent amidotransferase reaction that replaces the oxygen on C-2 with an amino group to yield 2-amino,6-oxy purine nucleoside monophosphate, or as this compound is commonly known, guanosine monophosphate.

What is the freezing point of a solution prepared from 45.0 g ethylene glycol (C2H6O2) and 85.0 g H2O? Kf of water is 1.86°C/m.
Andrews [41]

Answer:

T_{sol}=-15.9\°C

Explanation:

Hello,

In this case, we can analyze the colligative property of solutions - freezing point depression - for the formed solution when ethylene glycol mixes with water. Thus, since water freezes at 0 °C, we can compute the freezing point of the solution as shown below:

T_{sol}=T_{water}-i*m*Kf

Whereas the van't Hoff factor for this solute is 1 as it is nonionizing and the molality is:

m=\frac{mol_{solute}}{kg\ of\ water}=\frac{45.0g*\frac{1mol}{62g} }{85.0g*\frac{1kg}{1000g} } =8.54m

Thus, we obtain:

T_{sol}=0\°C+(-8.54m*1.86\frac{\°C}{m} )\\\\T_{sol}=-15.9\°C

Best regards.

Write the formula of the structure that would have the greatest internuclear distance between the pairs.
Reika [66]

An element's electronegativity determines whether it is ionic or non-ionic. Fluorine has the most electronegativity while iodine has the lowest, which means that the Cs I ionic bond's power of attraction is at its lowest, allowing for the largest possible distance between their molecules.

<h3>By intermolecular contact, what do you mean?</h3>

The attracting and repellent forces that develop between the molecules of a substance are referred to as intermolecular forces (IMF), which is sometimes shortened. These forces act as a bridge between the individual molecules of a substance. Intermolecular forces are primarily responsible for the physical and chemical properties of matter.

<h3>Which four intermolecular interactions are there?</h3>

The following are the four main intermolecular forces: Van der Waals dipole-dipole interactions < Van der Waals dispersion forces <Ionic bonds <Hydrogen bonds .

A student has a solution with a pH of 7. The student adds HF, hydrogen floride, to the solution, hoping to increases the pH of t
Allushta [10]
Low pH = high acidity.
HF has a very low pH, so when added to a solution, it will lower the pH of the solution and therefore make it more acidic. So the answer should be B.
