Answer:

98.6 g/mol.

Explanation:

Equation of the reaction

HX + NaOH--> NaX + H2O

Number of moles = molar concentration × volume

= 0.095 × 0.03

= 0.00285 moles

By stoichiometry, 1 mole of HX reacted with 1 mole of NaOH. Therefore, number of moles of HX = 0.00285 moles.

Molar mass = mass ÷ number of moles

= 0.281 ÷ 0.00285

= 98.6 g/mol.

Explain, in your own words, why different elements produce different colors of light when heated.
fgiga [73]
Different elements produce different colors of light when heated because the electrons in these elements have different permissible energy levels. When an element is heated, the electrons inside it become excited and move to an higher energy level from the ground state. When the electrons drop from this higher energy level, they typically emit energy quantum, the color of the light that is observed at this stage depends on difference that exist in the two energy levels.<span />

We must __________ forces to calculate net force if the forces are going in OPPOSITE directions.
Virty [35]

Answer:

subtract

Explanation:

To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.

  • The net force is the resultant force acting on a body.
  • This resultant force is the single force that will produce the same effects as all given forces.
  • When forces are directed oppositely on a body, they are subtracted from each other to find the net force.

Carbon-14 undergoes radioactive decay in the reaction above. Determine the type of radiation emitted in this reaction and descri
Drupady [299]

<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.

<u>Explanation:</u>

Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.

In beta-minus decay, a neutron gets converted to a proton and an electron.

The equation for the beta-minus decay of carbon-14 follows the reaction:

_6^{14}\textrm{C}\rightarrow _7^{14}\textrm{N}+_{-1}^0\beta

In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.

In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.
