Here we have to identify the sample which need more energy to heat the sample 1 degree Celsius.
Among the given elements magnesium will require more energy than the others to heat.
As per the definition of specific heat of a compound, the amount of heat required to increase the temperature of the material 1 degree Celsius is the specific heat of the material.
The given data are-
substance specific heat
Lead 0.129
Tin 0.21
Silver 0.235
Iron 0.449
Calcium 0.647
Granite 0.803
Aluminium 0.897
Magnesium 1.023
From the given data lead, magnesium, iron and aluminium have the specific heat 0.129, 1.023, 0.449 and 0.897 respectively. Thus magnesium will require more energy than the others to heat.
Explanation:
<em>(</em><em>P1V1</em><em>)</em><em>/</em><em>T1</em><em>=</em><em>(</em><em>P2V2</em><em>)</em><em>/</em><em>T2</em>
<em>(</em><em>1</em><em>5</em><em>X</em><em>5</em><em>)</em><em>/</em><em>2</em><em>9</em><em>7</em><em>=</em><em>(</em><em>p2x2</em><em>.</em><em>5</em><em>)</em><em>/</em><em>4</em><em>7</em><em>3</em>
<em>p2</em><em>=</em><em>47.78cmHg</em>
The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.
Carbon is known as a tetravalent compound.
It has four electrons in its outermost shell. It forms a covalent bond with other compounds.
The number of neutrons. = 6
Number of electrons = 6
Number of protons = 6
So the atomic number of the compound is,
The atomic number of an element = Number of protons present in its nucleus
The number of protons given in the compound is 6.
So the atomic number of the compound is also 6.
Carbon has six atomic numbers.
Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.
