Answer:
A substance whose molecules do not take up space or interact with one another
Answer:
Kc = 12.58
Explanation:
Kc = [0.229]^2*[0.687]^6/[0.221]^4*[0.5685]^3
Kc = (0.052441)(0.10513)/(0.002385)(0.18373)
Kc = 0.0005513/0.000438
Kc = 12.58
Hope that helps!!
Based on the graph you can see that after introduction of the vaccine in 1960 there was a sharp decline in US measles cases. Then over the 1960s as immunization numbers increased the measles cases in the US once again sharply declined and except for the occasional breakout remained at 0 or near zero for decades.
Glass is not a living organism, so it is <u>abiotic</u>.
Answer:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Explanation:
This is the reaction:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Let's verify the ions charges
Cu(NO₃)₂ → Cu²⁺ + 2NO₃⁻
NaOH → Na⁺ + OH⁻
Cu(OH)₂ → Cu²⁺ + 2OH⁻
NaNO₃ → Na⁺ + NO₃⁻
