3. Element X has two isotopes, Isotope A and Isotope B. A sample of element X consists of 60.1% Isotope A and 39.9% Isotope B. The atomic mass of Isotope A is 68.926 amu, and the atomic mass of Isotope B is 70.925 amu. Based on this information, which TWO statements are true? Isotope A is more abundant than Isotope B. Isotope B is more abundant than Isotope A. The average atomic mass of element X is less than 69 amu. The average atomic mass of element X is greater than 69 amu. The average atomic mass of element X is greater than 70 amu.

hloride, what is the mass of calcium in

explanation:

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
