Answer:
it holds reactant molecules in a good position for then to react
Answer: A
because electron mass is so small that they aren't accounted for the overall mass of an atom. Electrons are smaller than protons and neutrons.
Answer is: <span>daughter nucleus is zinc.
</span>Nuclear reaction 3: ⁶⁴Cu → ⁶⁴Zn + e⁻ + electron antineutrino.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from
an atomic nucleus.
There are two types of beta decay: beta minus and beta
plus.
In beta minus decay, neutron is converted to a proton and
an electron and an electron antineutrino and </span><span>atomic number Z is increased by one</span>.

Answer:
K = 0.2
Explanation:
Based on the chemical dissociation of N₂O₄:
N₂O₄ ⇄ 2NO₂
The equilibrium constant, K, of the reaction is:
K = [NO₂]² / [N₂O₄]
Now, if 20% of N₂O₄ is dissociated, 80% remains as N₂O₄ = 0.8mol/L = 0.8M
as 20% is dissociated, 0.2moles of N₂O₄ were dissociated and 0.2*2 = 0.4mol/L of NO₂ are produced.
Replacing in K:
K = [0.4M]² / [0.8M]
<h3>K = 0.2</h3>
