Answer is: C. The FDA tests give reliability to the results of improved health obtained by each company.
The FDA (The Food and Drug Administration) is a federal agency of the United States Department of Health and Human Services.
The FDA controls food safety, tobacco products, dietary supplements, prescription, pharmaceutical drugs, vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices, cosmetics and animal food.
Answer:
Yes
Explanation:
An object's weight can change, depending on its location, relative to the object of discussion. For example, we don't notice the change, but the farther away we are from Earth's core, the less we weigh. This means one would weigh more in a valley than they would on a mountain. The formula for gravity is F=G((msub1)(msub2)/r^2), where F is the force of attraction, G is the universal gravitational constant, msub1 is the mass of the first object, msub2 is the mass of the second object, and r is the distance between the two objects.
Answer:
Part A:
Order: K<Rb<Cs
Part B:
Order: O<C<Be
Part C:
Order:CL<S<K
Part D:
Order:Mg<Ca<K
Explanation:
Atomic Size:
It is the distance from the center to atom to the valance shell electron. It is very difficult to measure the atomic size because there is definite boundary of atom.
Trend:
Moving from top to bottom in a group, Atomic Size increases.
Moving from left to right in a period, Atomic size generally decreases.
On the basis of above trend we will solve our question:
Part A:
All elements belong to Group 1:
Moving from top to bottom in a group, Atomic Size increases.
Order: K<Rb<Cs
Part B:
All elements belong to 2nd Period:
Moving from left to right in a period, Atomic size generally decreases.
Order: O<C<Be
Part C:
S belongs to 3rd Period, K, Cl belong to 4th period
Order:CL<S<K
Part D:
Mg is above Ca in group 2 and K is before Ca in 4th period
From trends described above:
Order:Mg<Ca<K
All three molecular nitrogen, carbon monoxide, and cyanide ion are isoelectronic but CO and CN⁻ are toxic as compared to N₂ because N₂ has very high bond energy due to the presence of triple bonds making it stable in comparison to others.
<h3>What is Isoelectronic species?</h3>
The phrase "isoelectronic species," which means "same electric" or "equal charge," describes two atoms, ions, or molecules with the same electronic structure and the same amount of valence electrons. Chemical species that are isoelectronic often have identical chemical characteristics. It is referred to as having the same isoelectronic or being isoelectronic to other atoms or ions with the same electronic configurations.
