RUDIKE [14]

If the volume exiting the large intestine were 364 mL, then it would most likely indicate a case of diarrhea. This condition may lead to dehydration.

<h3>Diarrhea: causes and diagnosis</h3>

Diarrhea is an unhealthy condition that occurs when the body excretes an excessive amount of water.

Diarrhea must be treated because this condition can lead to dehydration (it may even lead to death in severe cases).

Both diarrhea and vomiting may lead to the loss of body fluids.

A drop of gasoline has a mass of 22 mg and a density of 0.754 g/cm3. What is its volume in cubic centimeters?
ArbitrLikvidat [17]
1.22 mg is the same as .022 grams. One gram equals 1000 mg. Convert mg to grams  by dividing mg by 1000mg/gm. Volume = mass over density. Volume equals .022 grams over .754 grams/cm3 which equals .029 or .03cm3. 2.weight in kg times gravity constant. Weight in newtons equals 10kg times 9.8m/s2 that equals 98 newtons.

nika2105 [10]

Answer:

3.50*10^-11 mol3 dm-9

Explanation:

A silver rod and a SHE are dipped into a saturated aqueous solution of silver oxalate, Ag2C2O4, at 25°C. The measured potential difference between the rod and the SHE is 0.5812 V, the rod being positive. Calculate the solubility product constant for silver oxalate.

Ag2C2O4 -->  2Ag+  +  C2O4 2-

So Ksp = [Ag+]^2 * [C2O42-]

In 1 L, 2.06*10^-4 mol of silver oxalate dissolve, giving, the same number of mol of oxalate ions, and twice the number of mol (4.12*10^-4) of silver ions.

So Ksp = (4.12*10^-4)^2 * (2.06*10^-4)

= 3.50*10^-11 mol3 dm-9

How can i find nuclear charge and overall charge while only knowing the atomic mumber, number of protons and electrons?​
Mazyrski [523]

Explanation:

An atom is made up of:

  • Protons which are the positively charged particles
  • Electrons are negatively charged
  • Neutrons carry no charges.

Atomic number is the number of protons in an atom.

To find the nuclear charge:

    We use the effective nuclear charge formula:

   Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)

The shielding electrons are the non-valence electrons in the inner orbitals.

For example:

  Ne:

          atomic number = 10

          Effective nuclear charge = 10 - (2) = 8+

   Number of non-valence electrons is 2

The effective nuclear charge is 8+

Overall charge:

        Charge = number of protons - number of electrons

  For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.
