Answer is B) - neutrons.


Both protons and neutrons contribute to the mass of an atom. But ₈¹⁷O atom has atomic number as 8. Hence, number of protons is 8. Atomic mass of the given atom is 17.


Atomic mass = number of protons + number of neutrons


Hence, number of neutrons in the given atom is 17 - 8 = 9.


So, the number of neutrons is greater than the number of protons. Hence the greatest composition of ₈¹⁷O atom is neutrons by mass.

Do the ch3f molecules appear to attract each other much? briefly describe their interaction.
suter [353]

Neither attract much nor allows it be free.

How the molecules behave in such way?

Because fluorine has a higher electronegativity than carbon and hydrogen, CH3F possesses a non-zero dipole moment. As a result, fluorine draws a partial negative charge whereas other atoms (such as carbon or hydrogen) draw a partial positive charge, leading to a non-zero dipole moment in CH3F. Lewis' structure, CH3F, is made up of one carbon atom, three hydrogen atoms, and one fluorine atom. Carbon is the key atom in the CH3F lewis structure because it is the least electronegative. The CH3F lewis dot structure consists of 3 lone pairs and a total of 4 bound pairs.

Properties of CH3F

  • It molar mass is 34.03 g/mol.
  • The density of CH3F is 1.4397 g/L and 0.557 g/cm³ at saturated pressure and temperature.
  • The melting point of CH3F is -137.8ºC and the Boiling point is -78.4ºC.
  • Its vapor pressure is 3.3 MPa.
  • Its IUPAC name is Fluoromethane.

What is the pH of a solution with hydroxide ion concentration of 0.005
Julli [10]

Answer:

pH = 11.7

Explanation:

pOH= -log [OH]=-log[0.05]

=2.3

pOH+pH= 14

pH= 14-2.3= 11.7

Claim The student hopes the samples are gold, which has a density of 19.3 g/cm3 . A local geologist suggested that samples might
spin [16.1K]

Answer:

Pyrite.

Explanation:

In this case, for the given samples, we compute the densities considering that the volume of each sample is computed by the difference between the volume of the water + sample and the volume of water:

\rho_1=\frac{50.25g}{(60.3-50.1)mL}=4.92g/mL\\ \\\rho_2=\frac{63.56g}{(62.5-49.8)mL}=5.01g/mL\\\\\rho_3=\frac{g}{(61.5-50.2)mL}=5.10g/mL\\\\\rho_4=\frac{55.35g}{(56.7-45.6)mL}=4.99g/mL\\\\\rho_5=\frac{74.92g}{(65.3-50.3)mL}=4.99g/mL\\\\\rho_6=\frac{67.78g}{(60.8-47.5)mL}=5.10g/mL

Therefore, since the density of the samples are closer to the density of pyrite (5.01 g/cm³) we conclude that the samples are more like to be pyrite.

Best regards.

This indicator becomes colored when the solution is no longer acidic.
Irina-Kira [14]

Answer:

Is pink in base solution, it provides a visual signal that a solution has changed from acid to a base, is colorless in acid solution.

Explanation:

As all the indicator, phenolphtalein has the property that turns pink when the solution that you have reaches a value of a pH of 9 or above. From 0 to 8 in a pH scale, is colorless. This point in which an indicator changes is it called equivalence point.
