I think there might be just 4 or 5 chloropropene.
Answer:
The exact molecular mass is 18.01528 g/mol
Explanation:
Find this by adding the molecular masses of two hydrogen atoms and one oxygen atom.
Answer:
Corrosion is the process of deterioration of materials as a result of chemical, electrochemical or other reactions. Rusting is a part of corrosion and is a chemical process which results in the formation of red or orange coating on the surface of metals. ... Rust or rusting can affect only iron and its alloys.

Answer:
Some of the physical and chemical properties of magnesium are:
-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.
-Magnesium is closely related to manganese and magnetite.
-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.
-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element
2nd answer:
Physical Properties of Magnesium: ”I’m a highly stable element, so you can count on me”
Chemical Properties of Magnesium: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon

Answer:
320 g
Step-by-step explanation:
The half-life of Co-63 (5.3 yr) is the time it takes for half of it to decay.
After one half-life, half (50 %) of the original amount will remain.
After a second half-life, half of that amount (25 %) will remain, and so on.
We can construct a table as follows:
No. of Fraction Mass
half-lives t/yr Remaining Remaining/g
0 0 1
1 5.3 ½
2 10.6 ¼
3 15.9 ⅛ 40.0
4 21.2 ¹/₁₆
We see that 40.0 g remain after three half-lives.
This is one-eighth of the original mass.
The mass of the original sample was 8 × 40 g = 320 g
