Answer:
The correct option is: bent 109°
Explanation:
Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or <u>bond pair of electrons</u>.
The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.
<u>Given molecule</u>: XY₂, having two lone pairs around the central atom X.
Since the molecule XY₂ has <u>two lone pairs</u> and <u>two bond pairs</u> of electrons. Therefore according to the VSEPR theory, the given molecule has a <u>bent molecular geometry with 109° bond angle.</u>
Answer : The pressure it exert under these new conditions will be, 87 atm
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 19 atm
= final pressure of gas = ?
= initial volume of gas = 100 L
= final volume of gas = 20 L
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Therefore, the pressure it exert under these new conditions will be, 87 atm
Answer:
- <u><em>50% of the offspring will have green pods.</em></u>
Explanation:
Use a upper case to identify the dominant allele and lower case to identify recessive allele.
<em>A homozygous pea plant</em> would be YY or gg. The <em>homozygous recessive pea pleant</em> would be gg (YY is dominant).
<em>A heterozygous pea plant</em> would be Yg (or gY which is the same).
The <em>Punnett Square </em>for the cross between a <em>homozygous recessive pea plant</em> (gg) and a <em>heterozygous pea plant</em> (Yg) would be:
g g
Y Yg Yg
g gg gg
Hence, <em>the offspring will have</em> two Yg, which would be yellow pods, and two gg which would be green pods.
That is, 50% of the offspring will have yellow pods and 50% will have green pods.
