Among He, Ne, Ar, and Kr, krypton (Kr) would be most likely to form a compound with fluorine. It's one of the heavier noble gases, which can form compounds with highly reactive elements like fluorine due to their slightly less firm hold on outermost electrons.
The elements in Group 18 are noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are known for their low reactivity because they have fully filled valence shells. However, the three heaviest noble gases - krypton, xenon, and radon - can react with fluorine to form fluorides, with xenon fluorides being the most well-researched among other noble gas compounds.
Among the options provided (He, Ne, Ar, Kr), krypton (Kr) would be the most likely to form a compound with fluorine. This is due to krypton's bigger size as it descends the periodic table, which slightly decreases the grip on its outermost electrons, making it marginally more likely to react with extremely reactive elements like fluorine.

(2) 236 K (4) 371 K
Answer:
3= 310. k
Explanation:
how to convert 37 Celsius to Kevin is to add 273.15 to 37 then you get 310.15 Kevin then you round that number to the nearest whole and you get 310 and that is your answer. please give me brainiest
b. False
Answer;
The above statement is false
Explanation;
Photosynthesis is the biological conversion of light or electromagnetic energy from the Sun into chemical energy. It occurs in green plants, algae, and some types of bacteria, and requires a series of biochemical reactions.
In photosynthesis, carbon dioxide and water react with one another in the presence of light and a chemical known as chlorophyll to produce a simple carbohydrate and oxygen.
Fossils of what are thought to be filamentous photosynthetic organisms have been dated at 3.4 billion years old. Geological evidence suggests that oxygenic photosynthesis, such as that in cyanobacteria, became important during the Paleoproterozoic era around 2 billion years ago.
I put true into the answer and it was wrong so it is actually FALSE.
The answer above is incorrect.
1. Double-Replacement reactions
2. Decomposition
3. Combustion
4. Syntesis
5. Single replacement
Given
Chemical equations
Required
Type of reaction
Solution
1. 2AgNO₃ + MgCl₂ ⇒ 2AgCl + Mg(NO₃)₂
Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant
2. 2KBr⇒2K +Br₂
Decomposition
Single compound breaks down in to 2 or more products
3. C₃H₈ + 5O₂ ⇒ 4H₂O + 3CO₂
Combustion
Hydrocarbon and Oxygen reaction and form water and carbon dioxide
4. NaO + H₂O ⇒ NaOH
Syntesis
2 or more reactants combine to form a single product
5. Zn + CuCl₂ ⇒ZnCl₂ + Cu
Single replacement
One element replaces another element from a compound
one atom of nitrogen and one atom of oxygen.
B.
two atoms of nitrogen and one atom of oxygen.
C.
two atoms of nitrogen.
D.
one atom of nitrogen.
Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.
The correct option is C.
Explanation:
Nitrogen gas has the chemical formula , which means that two atoms of nitrogen element combined to form nitrogen gas.
The combination of two atoms of element nitrogen produce dinitrogen atom.
Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.
2 atoms of nitrogen element
N + N =
the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
A. glass
B. pottery
C. ice
D. gold
Gold is malleable while glass, pottery, and ice are not.
Malleability is the ability of a material to be hammered or rolled into thin sheets without breaking. Gold is highly malleable and can be shaped into various forms, such as jewelry and gold leaf. Glass, pottery, and ice, on the other hand, are not malleable because they will break or shatter when hammered or rolled into thin sheets.
Gold is malleable because its metallic bonds allow its atoms to slide past one another without breaking. Glass, pottery, and ice lack these bonds and have a more rigid structure, making them non-malleable. Instead, glass and pottery are brittle, while ice can fracture under stress due to its molecular structure.
