The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as
dn=70.7kg
<h3>What is the enthalpy change for the reaction?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2k+s----->K2S
Therefore
KS+K----->K2S
Therefore
dn=dn1+dn2
dn=32.5+38.2
dn=70.7kg
In conclusion, the enthalpy change is
dn=70.7kg

Cool whats the question ma dude?
Answer:
catenation
Explanation:
Carbon atoms have four electrons to share in bonding environments to get to the ideal octet. To do this, it bonds with other carbon molecules, called catenation. Catenation is the ability of an atom to bond and share electrons with other atoms of its kind.
Answer:
Higher the inter particles forces of attraction, higer the melting point.
Based on this wish you can arrenge them in a required order.
Explanation:
<u>Answer</u>:
Eye colour is one example of a trait caused by the concentration of melanin in genes.
<u>Explanation</u>:
Eye colour is decided based on two distinct factors- pigmentation of the eye’s iris and scattering of the light by the 'stroma of the iris'. It is a 'polygenic phenotypic' character in a human being.
The pigmentation of the iris varies between brown and black, that all depends on melanin concentration in the iris stroma, iris pigment epithelium and the cellular density of trauma. Further, the eye colour genetics are complicated and multiple genes are responsible for same.
