Number 1 is the correct answer
Answer:
moles H = 2 x 0.0649=0.130
ions = 0.130 x 6.02 x 10^23=7.81 x 10^22
Explanation:
Answer:
B
Explanation:
Because Im Built Different
Answer:
Single-Replacement Reaction
General Formulas and Concepts:
<u>Types of Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define reaction</u>
CaCl₂ + F₂ → CaF₂ + Cl₂
<u>Step 2: Identify backplate</u>
Single-Replacement Reactions: A + BC → AB + C
BC = CaCl₂
A = F₂
AB = CaF₂
C = Cl₂
Answer: A. an electron
<u>Beta particles are electrons or positrons (electrons with positive electric charge or antielectrons).</u> Beta decay is a type of radioactive decay in which a beta ray is emitted from an atomic nucleus.
<u>Beta decay occurs when, in an unstable nucleus with too many protons or too many neutrons, one of the protons or neutrons transforms into the other.</u> In beta minus decay, a neutron is broken down into a proton, an electron, and an antineutrino (the neutrino antiparticle, meaning it has an opposite charge to the neutrino). In beta decay plus, a prototype breaks down into a neutron, a positron and a neutrino.
