Using natural gas is cheaper from other fossil fuels when used for personal needs. It also doesn't pollute the ground or the underground water.
Answer:polar covalent bond
Explanation:
Compounds are formed ether by donating, receiving or sharing of electrons making the bonds between them to be ionic, or covalent .
Now according to the rule of type of bond assignment due to electronegativity difference of atoms
---When the electronegativity difference is less than 0.5, the bond formed is nonpolar covalent.
---When the electronegativity difference is between 0.5 and 1.6, the bond is considered polar covalent
---When the electronegativity difference greater than 2.0, then the bond is ionic.
Therefore, When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bonded by polar covalent bond eg HCl bond , CCL4 bond
Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>
Answer:b
Explanation:
The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively.
