Sure, what's the questions and I can get it for you, and if need further assist you.
Answer: Option B) Atom
Explanation:
An atom is the simplest particle of an element that can retain all the chemical properties of the element, and therefore take part in a chemical reaction.
Thus, an atom of zinc (Zn) represent fully the entire properties of elemental Zinc. For instance: an atom of zinc has a mass of 65.38g.
Answer:
unless it is acted upon a forcd
Answer:
1,300,000,000,000
Explanation:
1.3 x 10^12
We want to convert this from scientific notation.
Tip: in scientific notation the exponent tells you how many place you move the decimal point over. If the exponent is negative you move the decimal point to the left. Ex. For, 4.1 x 10^-8, we would move the decimal point over 8 times to the left to get .00000041. When the exponent is positive we move over to the right. Ex. For, 7.6 x 10^7 we would move the decimal point over 7 times to the right to get 76,000,000
So to convert 1.3 x 10^12 we simply move over the decimal point over 12 times to the right.
1.3 x 10^12 ------> 1,300,000,000,000
Our answer is 1,300,000,000,000
Molecular mass of HCl :
H = 1.00794
Cl= 35.453
HCl :
1.00794 + 35.453 = 36.46094 g/mol
hope this helps!
