PolarNik [594]3 years ago
6 0

Answer:

33.2 moles y 1994 gramos.

Explanation:

¡Hola!

En este caso, dado que es posible para nosotros relacionar moles con gramos por medio de la masa molar y moléculas con moles por medio del número de Avogadro, resulta factible para nosotros primero calcular las moles en las moléculas dadas y de esta manera luego calcular los gramos, teniendo en cuenta una masa molar de 60.05 g/mol ya que el vinagre se puede estudiar como ácido acético (CH3COOH):

2x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=33.2mol

Seguidamente, calculamos los gramos:

33.2mol*\frac{60.05g}{1mol}=1994g

¡Saludos!

The value of A for an atom containing 12 protons, 12 electrons and 16 neutrons is
Zepler [3.9K]

Answer: A = atomic number = 12

Explanation: A (atomic number) defines the chemical element. It is the numbervof protons or electrons. Neutron numbers may vary, produving isotopes of differing atomic mass. This isotope has atomic mass 28. The atomic number 12 = carbon. C28 does not really exist. If it could be produced it would be radioactive with an almost zero halflife.

Which of the following is false about a neutral atom of hydrogen?
Nesterboy [21]

Answer: Option (C) is the correct answer.

Explanation:

A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.

Basically in a neutral atom electrons are present in their parent shell.

For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is 1s^{1}.

Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.

Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
