La primera instrucción es verdadera, la segunda es falsa porque dos elementos no pueden tener el mismo número de masa (excepto azufre y argón) Estrictamente hablando, No. Puede tener 2 (o más) elementos con el mismo 'número de masa atómica', lo que significa que el número total de nucleones (neutrones de protones) es el mismo. En el ejemplo dado en una respuesta anterior, el azufre tiene un isótopo con el número de masa atómica 36 (16p 20n) y Argón también tiene un 36 (18p 18n). La tercera declaración es verdadera, si tiene un número diferente de neutrones, entonces es un isótopo. La cuarta declaración es falso. Espero que esto te ayude.
Answer:
Take this as a hint :
The value of the mole is equal to the number of atoms in just 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called avogadro's numberr (6.0221421 x 1023).
Explanation:
Explanation:
Density is defined as the mass of the substance divided by the volume of the substance.
Mathematically, Density =
Since, it is given that mass is 18,754 kg and density is 0.788 g/. We know that there are 1000 grams in 1 kg.
So, 18,754 kg equals 18,754000 grams.
Hence, calculate the volume of the waste collection tank as follows.
Density =
0.788 g/ =
volume = 23799492.38
It is known that 1 equals 0.001 liter. So, 23799492.38 equals 23799.49 liters.
Thus, we can conclude that volume of the waste collection tank is 23799.49 liters.
Answer: The right conjugate of is
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
Here, is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms which is a conjugate acid.
Thus the right conjugate of is
