How many neutrinos does an element have if it's atomic number is 47 and it's mass number is 169

Chemistry
1 answer:
Stells [14]3 years ago
7 0

This element would have 122 neutrons.

Atomic mass is the accumulation of neutrons and protons.

169 - 47 = 122.

Therefore, there are 122 neutrons.

cestrela7 [59]

Answer;

Solvent

Explanation;

-A solution is a homogeneous mixture that is made of two or more substances.  In other words, It is a mixture in which one of the substances dissolves in the other. The substance which dissolves is called the solute while the substance that dissolves the solute is called the solvent.

-In a solution of a carbonated beverage, water acts as the solvent which dissolves the components added as solute to make the beverage. These components include sugars and other types of salts such as sodium citrate, all dissolved in water.

For H3PO4, Ka1 = 7.3 x 10^-3, Ka2 = 6.2 x 10^-6, and Ka3 = 4.8 x 10^-13. A 0.10 M aqueous solution of Na3PO4 therefore would be
zmey [24]

Answer:

The aqueous solution of Na_{3} Po_{4} therefore would be "strongly basic."

Explanation:

Strongly basic because the Na_{3} Po_{4} is completely an ionic compound. These compound can be 100% splitted into metal ions and hydroxide ion when used in the aqueous solution. Each moles dissolves which can give rise to mole of hydrogen ions when used in the solution. Whereas strong bases are not soluble in water as well.  in the presence of water equilibrium can also be achieved. A strong base has the capability which can just remove the proton from the molecule.

Explain why the pressure in a sealed container of gas decreases when heat is added to the system?
weeeeeb [17]

Answer:

the question is bogus

see explanation

Explanation:

explain why the pressure in a sealed container of gas decreases when heat is added to the system?

when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!

IT DOES NOT DECREASE

PV =nrT

IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE  NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE

Figure 2 represents part of the structure of graphite.
Paul [167]

The answers include the following:

  • Graphite conducts electricity because it has delocalised electrons which makes it possible for the electrons to move freely.
  • Graphite is slippery because it has layers which makes it possible for the atoms to slide over each other.

<h3>What is Graphite?</h3>

This is referred to as an allotrope of carbon and it is the most stable form. it is used in the production of substances such as pencil, electrode etc.

Graphite is able to conduct electricity because of the presence of delocalized electrons and is slippery due to its atoms being able to slide over one another.
