Answer:
animals unlike us adapt faster to heat/cool weather or water
Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P
Answer:
As 1 mole =6.023×10^23 atoms
So, No of moles in 2.75×10^24 atoms = 4.56 moles
So,~4.56 moles are there in 2.75 ×10^24 atoms of carbon
You are given
the density of helium and neon gas mixture which is 0.1562 grams per liters at 40.2degC and 296 torr. You are required to find the mole fraction of neon in this mmixture.
c = dRT/P
c = (0.1562g/L)(0.08206 L-atm/mol-K)(40.2+273)K/296torr(1atm/760torr)
c = 10.31 g/mol
since helium is 4 g/mol
mole fraction of neon = (10.31 - 4) / 10.31 = 0.612
It is probably a worker bc it lets things in and out of the cell and stops harmful things from entering the cell
Calculate the pOH where [OH⁻]=4.7×10⁻³M:
pOH=-log[OH⁻]
pOH=-log(<span>4.7×10⁻³)
pOH=2.33
Calculate [OH</span>⁻] if the pOH is 1.34:
pOH=-log[OH⁻]
10^(-pOH)=[OH⁻]
[OH⁻]=10^(-pOH)
[OH⁻]=10^(-1.34)
[OH-]=0.0457M or [OH⁻]=4.57×10⁻²M
Calculate pH if the [OH⁻] is 1.74×10⁻²M:
[H⁺]=K(w)/[OH⁻] or pOH=-log[OH⁻]
[H⁺]=(1×10⁻¹⁴)/(1.57×10⁻²) pOH=-log(1.74×10⁻²)
[H⁺]=6.369×10⁻¹³M pOH=1.759
pH=-log[H⁺] pH=14-pOH
pH=-log(6.369×10⁻¹³) pH=14-1.759
pH=12.2 pH=12.2
I hope this helps. Let me know if anything is unclear.
