Of the same element with different mass numbers are called isotopes 3) Isotopes have the same number of protons but different numbers of neutrons in their nuclei. ... The 63Cu isotope has 63 - 29 = 34 neutrons. The 65Cu isotope has 65 - 29 = 36 neutrons.
All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.

I was flung towards the atmosphere. Slowly but surely, I made my way inside. On my way there, I began to heat up. I began to vibrate rapidly, and I noted it happened as I entered the atmosphere. I think it was because we sped up so much, but I can't say for sure because I'm an air particle... However, I do know that I am now a heated air particle due to friction and movement from entering the atmosphere. I think I'll cool down on my descent, I don't know that I can get much hotter than this.
Answer:
if my calculation are correct, it's 295 grams
Explanation:
because liters converted to grams is .1=100 so if you take 2.95 times 100, it equals 295
Hey there!
Given the reaction:
B + H⁺ => HB⁺
At half-equivalence point : [B] = [HB⁺]
=> [B] / [HB⁺] = 1
Henderson-Hasselbalch equation :
pH = pKa + log ( [B] ) / ( HB⁺)]
pH = 14 - pKb + log ( 1 )
pH = 14 - 7.95 + 0
pH = 6.05
Answer C
Hope that helps!
