IT IS HIGHLY EXOTHERMIC REACTION AND HEAT IS PRODUCED IN LARGE AMOUNT BECAUSE WHEN WE ADD ACID TO WATER HIGH ENERGY AND HEAT IS PRODUCED
Answer:
DNA is expressed as a gene which determines the expressed trait of the organism.
Explanation:
Answer : Linear
Explanation : Hydrogen Cyanide (HCN) when drwan in the Lewis diagram shows carbon atom at the center with no lone electron pairs.
The carbon and nitrogen atoms are bonded through a triple bond which counts as "one electron pair".
The molecule has two electron pairs in all and appears to be linear.
Also, according to the VSEPR theory; the electron clouds on atoms around the carbon will try to repel each other.
They will get pushed apart, which gives HCN molecule a linear molecular geometry or shape.
The bond angle that is developed will be 180 degrees since it has a linear molecular geometry of HCN. The hybridisation observed in this molecule is SP.
Hello! :)
Chlorine is a halogen located in group 7A and period 3 of the periodic table.
We can write the electron configuration of this element. Since it is in period 3, the highest configuration level will be at 3.
Chlorine is also located in the p block (nonmetal) section of the table, so the final part of the written configuration will involve "3p".
Recall that:
S block: up to 2 electrons
P block: up to 6 electrons
Chlorine has 17 electrons
Fill in the order of s block to p block. The first level only goes up to an s block. The configuration should sum up to 17 total electrons in total.
We can write the configuration as:
Answer:
alloy,copper,gold, silver,cobalt
