Ir = [Xe] 4f14 5d7 6s2
<span>Rn = [Xe] 4f14 5d10 6s2 6p6 </span>
<span>Fe = [Ar] 3d6 4s2 </span>
<span>Pa = [Rn] 5f2 6d1 7s2 </span>
<span>Y = [Kr] 4d1 5s2 </span>
<span>Re = [Xe] 4f14 5d5 6s2 </span>
<span>So only Rhenium (Re) has an electronic configuration where the d orbital has 5 electrons in it.</span>
Answer:
I believe the answer is, 'If mass remains the same while the volume of a substance increases, the density of the substance will decrease.'
explanation: density= mass divided by volume, meaning that volume and density are inversely proportionate.
Explanation:
D, T<span>he total mass of hydrochloric acid used is less than 10 grams.
Conservation of mass, matter cannot be created or destroyed.</span>
Answer:
*thiamine
*thiamine
*pyruvate
"thiaminase
Explanation:
Beriberi is a vitamin deficiency disease caused by a deficiency in *THIAMINE* as this isa *THIAMINE*
precursor to the coenzyme which is used in the *PYRUVATE*reactions of the citrate cycle. Brown rice, in which the bran of the rice remains, is considered more nutritious than white rice, in part because this vitamin is not removed. Beriberi can also be caused by consuming foods that contain high levels of *THIAMINASE*, such as uncooked fish and silkworms.
Beriberi is a disease which is also called thiamine deficiency is caused as a result of deficiency in by a vitamin B-1. Beriberi disease can occur in two ways, as wet beriberi or dry beriberi.
Dry beriberi usually attack the nerves and later damage it and which lead to weakening of muscle and eventually paralysis of muscle.
On the other hand, Wet beriberi attack the heart as well as the circulatory system, which can result to heart failure in extreme condition.
Answer:
The elements with completely filled shells are classified as noble gases
That is why we only see noble gases on the rightmost corner of the periodic table, it is because they have the maximum number of electrons in a shell
<u>Examples of noble gases</u>
Helium , Neon , Argon and Krypton are some examples of noble gases
