If both objects have the same volume, but a different weight, than the densities are different. One has the greater density, while the other doesn't.

Explanation:

Density of a substance is defined as mass divided by its volume.

Mathematically,         Density = \frac{mass}{volume}

So, density is proportional to the mass of substance. Hence, an increase in mass will lead to increase in density of the substance also.

Whereas density is inversely proportional to volume of a substance. Hence, an increase in volume will lead to a decrease in density of the substance.

So, when densities of two objects that have the same volume, but one feels heavier than the other then it means mass of one object is greater than the other.

Hence, density of one object is greater than the other. That is why, one feels heavier than the other.

Calculate the Molar Mass in g/mol of Ammonium Sulfate, (NH4)2(SO4)
saw5 [17]

Answer:

132g/mol

Explanation:

The problem here is to find the molar mass of the compound in g/mol

To solve this problem, we simply sum the atomic masses of the atoms in the compound:

   (NH₄)₂ SO₄:

  Atomic mass of N  = 14g

   Atomic mass of H  = 1g

  Atomic mass of S  = 32g

  Atomic mass of O = 16g

So;

   Molar mass = 2[(14 + 4(1))] + 32 + 4(16)  = 132g/mol

Answer:

Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel.

There must be Fuel to burn.

There must be Air to supply oxygen.

There must be Heat (ignition temperature) to start and continue the combustion process.

Ouabain is a poison that binds to the Na+/K+ pump in the cell membrane and inhibits its action. The expected result of this pois
IRISSAK [1]

Answer: A loss of the ion concentration gradient that drives this process.

Explanation:Ouabain known as g-strophanthin, is a cardiac glycoside that can be medically used to treat hypotension.It acts by nhibiting the sodium - potassium (Na/K-ATPase) by causing a loss of the ion concentration gradient that drives it's process. Originally, it was a toxic plant that was used as an arrow poison in eastern Africa for hunting and warfare. Recently, Ouabain is synthesized by animals and secreted from the adrenal cortex to regulate body osmosis.

Compounds are substances that can be broken down by chemical means. They are categorized as pure substances due to their definite composition.

  • Compounds are substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
  • Properties of compounds differs from those of the constituent atoms.
  • Compounds are broken down by chemical means because they are products of chemical changes.
  • Several kinds of compounds exists through combinations of atoms.
  • Compounds have definite compositions
