Answer:

10g Carbon has more particles.

Explanation:

To Find

Which has more particles 10g of C or 10g of Ca

The molar mass of carbon is 12g and Calcium is 40g.

1 mole of  atom , molecule or ions contain Avagadro number (6.022×10∧23) of particles and also have a mass equal to it's molar mass.

For C,

12g C  will have 6.022×10∧23 atoms

10g C will have  \frac{10}{12} ×6.022×10∧23 atoms

=0.833 × 10∧23 atoms

For Ca,

1 mole Ca =40g

40g Ca will have 6.022×10∧23 atoms

10g Ca will have \frac{10}{40} ×6.022×10∧23 atoms

=0.25 × 6.022×10∧23 atoms

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal. T
SVEN [57.7K]

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal is True.

<u>Explanation:</u>

Nuclear Fission is the process in which splitting of a nucleus takes place that releases free neutrons and lighter nuclei. The fission of heavy elements like "Uranium is highly exothermic" and releases "200 million eV" compared to the energy that is released by burning coal which gives a few eV.

In the given example, it is obvious that the energy released from 1 gram of uranium is more than that of the energy released from 3 grams of coal because the amount of energy released during nuclear fission is millions of times more efficient per mass than that of coal considering only \frac{1}{10}^{th} part of the original nuclei is converted to energy.

Answer:

Adakah benar anda tidak boleh mencuci rambut, minum air sejuk dan

makan ais krim atau bersukan semasa haid? Terangkan jawapan anda.

Tidak, ini tidak benar, melakukan semua ini baik-baik saja. Seperti, tidak ada yang dapat mempengaruhi kita, kerana tidak bersambung dengan sistem kita. Juga, mohon maaf jika bahasa itu salah kerana saya menggunakan terjemahan Google.

Semoga ini membantu :)

A buffer contains the weak acid HA and its conjugate base A-. the weak acid has a p Ka of 4.82 and the buffer has a pH of 4.25.
klasskru [66]
<span>I think the correct answer is A. A buffer is a substance that resists small change in the acidity of a solution when an acid or base is added to the solution. Usually, a buffer involves a weak acid or a weak alkali and one of its salt.</span>
