Answer:
The nucleus in eukaryotes and the cytoplasm in prokaryotes
Explanation:
The nucleus is the largest organ in a eukaryotic cell which is responsible for the control of the cell activities based on processing of received information and cell administration. The nucleus is therefore, known as the cell cell control center for regulating the metabolism of the cell and administers the cell and cellular information with which proteins are made
The nucleus contains nucleolus and it is the store for the chromosomes, which play an important role in genetics, related to the synthesis and replication of DNA and RNA
The functions of the nucleus are spread out through out the cytoplasm of prokaryotes.
Answer:
691.29 K or 418.14 °C
Explanation:
Hello, at first the moles of oxygen gas are required:
![n_{O_2}=1.75 g * \frac{1mol O_2}{32 g O_2} =0.0547 mol](https://tex.z-dn.net/?f=n_%7BO_2%7D%3D1.75%20g%20%2A%20%5Cfrac%7B1mol%20O_2%7D%7B32%20g%20O_2%7D%20%3D0.0547%20mol)
Now, based on the ideal gas equation, we solve for the temperature:
![PV=nRT\\T=\frac{PV}{nR}\\T=\frac{1atm * 3.10 L}{0.0547 mol*0.082 \frac{atm*L}{mol*K} }\\T=691.29 K](https://tex.z-dn.net/?f=PV%3DnRT%5C%5CT%3D%5Cfrac%7BPV%7D%7BnR%7D%5C%5CT%3D%5Cfrac%7B1atm%20%2A%203.10%20L%7D%7B0.0547%20mol%2A0.082%20%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%20%7D%5C%5CT%3D691.29%20K)

Answer:
![\large \boxed{5.5 \times 10^{22}\text{ molecules of P$_{2}$O}_{5}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B5.5%20%5Ctimes%2010%5E%7B22%7D%5Ctext%7B%20molecules%20of%20P%24_%7B2%7D%24O%7D_%7B5%7D%7D)
Explanation:
You must calculate the moles of P₄O₁₀, convert to moles of P₂O₅, then convert to molecules of P₂O₅.
1. Moles of P₄O₁₀
![\text{Moles of P$_{4}$O}_{10} = \text{13 g P$_{4}$O}_{10} \times \dfrac{\text{1 mol P$_{4}$O}_{10}}{\text{283.89 g P$_{4}$O}_{10}} = \text{0.0458 mol P$_{4}$O}_{10}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20P%24_%7B4%7D%24O%7D_%7B10%7D%20%3D%20%5Ctext%7B13%20g%20P%24_%7B4%7D%24O%7D_%7B10%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20mol%20P%24_%7B4%7D%24O%7D_%7B10%7D%7D%7B%5Ctext%7B283.89%20g%20P%24_%7B4%7D%24O%7D_%7B10%7D%7D%20%3D%20%5Ctext%7B0.0458%20mol%20P%24_%7B4%7D%24O%7D_%7B10%7D)
2. Moles of P₂O₅
P₄O₁₀ ⟶ 2P₂O₅
The molar ratio is 2 mol P₂O₅:1 mol P₄O₁₀
3. Molecules of P₂O₅
![\text{No. of molecules} = \text{0.0916 mol P$_{2}$O}_{5} \times \dfrac{6.022 \times 10^{23}\text{ molecules P$_{2}$O}_{5}}{\text{1 mol P$_{2}$O}_{5}}\\\\= \mathbf{5.5 \times 10^{22}}\textbf{ molecules P$_{2}$O}_{5}\\\text{There are $\large \boxed{\mathbf{5.5 \times 10^{22}}\textbf{ molecules of P$_{2}$O}_{5}}$}](https://tex.z-dn.net/?f=%5Ctext%7BNo.%20of%20molecules%7D%20%3D%20%5Ctext%7B0.0916%20mol%20P%24_%7B2%7D%24O%7D_%7B5%7D%20%5Ctimes%20%5Cdfrac%7B6.022%20%5Ctimes%2010%5E%7B23%7D%5Ctext%7B%20molecules%20P%24_%7B2%7D%24O%7D_%7B5%7D%7D%7B%5Ctext%7B1%20mol%20P%24_%7B2%7D%24O%7D_%7B5%7D%7D%5C%5C%5C%5C%3D%20%5Cmathbf%7B5.5%20%5Ctimes%2010%5E%7B22%7D%7D%5Ctextbf%7B%20molecules%20P%24_%7B2%7D%24O%7D_%7B5%7D%5C%5C%5Ctext%7BThere%20are%20%24%5Clarge%20%5Cboxed%7B%5Cmathbf%7B5.5%20%5Ctimes%2010%5E%7B22%7D%7D%5Ctextbf%7B%20molecules%20of%20P%24_%7B2%7D%24O%7D_%7B5%7D%7D%24%7D)
Answer:
what is on the surface of the moon.
Explanation:
Answer:
I believe 1+
Explanation:
when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
