It can't be a viruses because it's a antibiotics
Helium would be the least I think
Answer:
The electric force is conservative.
Since
ΔK = −ΔU,
Kf − Ki =Ui −Uf.
We have,
Kf = 0
Ui = 0.
Thus Ki =Uf.
<u>so ,at 10 fm Uf = (2×10)−12 J.</u>
Round off .00042557 to three significant digits is = 0.000426
<h3>What is round of value ?</h3>
- If 5, 6, 7, 8, or 9 come after the number you are rounding, round it up. For instance, 40 is the result of rounding 38 to the nearest ten.
- If the numbers 0, 1, 2, 3, or 4 come after the number, round it down. If 33 is rounded to the nearest ten, it becomes 30.
- To estimate a certain number in a context, rounding is a process. Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up.
Given
The digit of 00042557

Answer:- Titanium(III)oxide
Explanations:- Titanium is a transition metal and we know that transition metals shows variable oxidation states. Charge for oxygen is -2. While writing the chemical formulas, we use criss cross means the charge of the anion becomes the subscript of the cation. Similarly, the charge of the cation becomes the subscript of the anion.
Here, it is important that we use the simple ratio of the charges for their subscripts. For example if the anion and cation has equal charges then no subscripts are used.
The given chemical formula is . From this formula, the subscript of Ti is 2 which is the charge of oxygen atom. Similarly the subscript of O is 3 which is the charge of titanium atom.
While writing names for the compounds containing transition metals then the charge of the transition metal is indicated by writing roman numeral next to the name of the metal.
When oxygen is bonded to the metal ions then these compounds are named as oxides. As the charge of Ti is +3, the name of the compound is Titanium(III)oxide.
