An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.
Here are the following solutions:
1. A
2. F
3. B.
Mol h2so4=0,6x3=1,8mol
MolOH-=Mol H+=2molh2so4=1,8x2=3,6mol
=> Mol NaOH=3,6mol=>V naoh= 3,6:4=0,9liters.
So, A is the correct answer
Your answer would be 1. Hope this Helps!
Answer:
2. Write balanced nuclear equations for the following situations. For each, be sure to show the parent element, the daughter element, and any particles emitted. For each element, use notation that includes atomic mass and atomic number. (12 points)
a. Actinium-225 decays by alpha decay. (3 points)
225 - 4 = 221, 89 - 2 = 87,
" 225/89 Ac = 221/87 Fr + 4/2 a "
b. Helium-6 decays by beta decay. (3 points)
neutron= 4-1=3 proton= 2+1=3
" 6/2 He = 6/3 Li + 0/-1 β "
c. Barium-141 and krypton-92 are produced by the bombardment of uranium-235 with a neutron. Complete the reaction:(3 points)
235/92 Ur + 1/0 n = 141/56 Ba + 92/36 Kr ?
d. Deuterium and tritium fuse to form helium-4. (3 points)
2/1 H + 3/1H = 4/2 He + 1/0 n
Explanation:
a p e x, and btw the deuterium and tritium are isotopes of hydrogen, your welcome :)
