Answer:
1.83moles
Explanation:
Given parameters:
Mass of methane given = 29.2g
Unknown:
Number of moles = ?
Solution:
To find the number of moles in this mass of a compound;
Number of moles =
Molar mass of CH₄ = 12 + 4(1) = 16g/mol
Now;
Number of moles = = 1.83moles
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance.
Answer:
dCDP
Explanation:
The nucleotide has hydrogen at it second carbon which means that it has deoxy pentose sugar which is written in small d as prefix.
The nitrogenous base is cytosine and it contains 2 phosphate groups which are attached to the 5 carbon of the pentose sugar means it is cytosine diphosphate.
<u>So, the abbrevation of the molecule is : dCDP</u>
Chemical change, because the atoms are being rearranged and we get a new substance.
