40×19.32/100=7.7=8×2=16Ca
35.5×34.30/100=12.1=12×2=24Cl
16×46.38/100=7.4=7×2=14O
<span>Atomic number and mass number for the carbon isotope with seven neutrons are:
Z,A = 6,13
There are 3 isotopes of carbon that are carbon 12, carbon 13 and carbon 14.
The carbon atom with seven neutron is carbon 13. Each carbon has 6 protons so its atomic number is 6 and when it has seven neutron then mass number will be (6 + 7) = 13
So, atomic number Z is 6 and mass number A is 13.</span>
Answer:
a base
Explanation:
first convert the pOH to pH, that way it will
be easy to decide.
formula:pOH+pH=14
pH=14-4.3=9.7
high pH tells us it's a base
Answer:hmm i think its C or A!
