Answer:
I^ -1 configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6
Explanation:
The electron configuration of iodine is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p5, but with the addition of an electron it gains another other to make it 5p6.
he could heat up the mixture
hope this help :)
Answer:
V ∝ abc
Explanation:
This task is a joint variation task involving only direct proportionality:
Direct variation is one in which two variables are in direct proportionality to each other. This means that as one increases, the other variable also increases and vice - versa.
Joint variation is one in which one variable is dependent on two or more variables and varies directly as each of them.
In this exercise:
If a ∝ b and a ∝ c, then a ∝ bc
Taking the above three proportionalities,
V ∝ a ∝ b ∝ c
V ∝ a ∝ bc
V ∝ abc
<h2>Answer : Option A) Arm and leg muscles and option D) Striated or skeletal muscle</h2><h3>Explanation : </h3>
Voluntary muscles are those muscles which are and can be consciously controlled.
These includes biceps, triceps which are the muscles that are present in arms.
The leg muscles are also voluntary muscles, with addition to this the striated or skeletal muscles are also classified as voluntary muscles.
It is seen that most of the skeletal muscles are attached to bones by bundles of collagen fibers known as tendons are controlled voluntarily.
