Respiration and Photosynthesis is different form each other because photosynthesis removes CO2 while respiration puts back CO2
I hoped this helped!
Answer:
Explanation:
molar volume=moles*given volume
for molar concentration we use two formulas molarity and molality
molarity=no of moles/volume
molality=no of moles/kilogram
Answer:
2.33g of iron (iii) chloride
50.0 mL of 5.00 M of sodium phosphate
FeCl3 + Na3PO4 > Fe(PO4) + 3NaCl
mol = conc × vol = 0.5 × 50/1000 = 0.025 mol Na3PO4
from the equation:
1 mol of Na3PO4 reacts with 1 mol FeCl3 = 3 mol of NaCl
0.025 mol = x
x = 0.0025 × 3 = 0.075 mol NaCl
mass = 0.075 g × 59 g/mol = 4.425 g NaCl
i guessed all of this so i dont know i it is correct
Answer:
Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the acidic buffer solution as:
![pH=pK_a+log\frac{[salt]}{[acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2Blog%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D)
Given that:-
[Acid] = 0.12 M
Volume = 3.0 L
pKa = 3.74
pH = 5.30
So,
![5.30=3.74+log\frac{[sodium\ formate]}{0.12}](https://tex.z-dn.net/?f=5.30%3D3.74%2Blog%5Cfrac%7B%5Bsodium%5C%20formate%5D%7D%7B0.12%7D)
Solving, we get that:-
[Sodium formate] = 4.36 M
Considering:
So,
So, Moles of sodium formate = 4.36*3.0 moles = 13.08 moles
Molar mass of sodium formate = 68.01 g/mol
The formula for the calculation of moles is shown below:
Thus,
Answer:
Assembly points.
Explanation:
Predetermined spots where everyone leaving the building should meet during a fire or fire drill are called assembly points.
This ultimately implies that, an assembly point is a designated safe location or area where different people are instructed to stay while being evacuated from a dangerous area such as during fire, gas explosion, flood or other emergency situations.
Simply stated, an assembly point is mainly a place of safety and succor for victims of a disaster, in the event of an evacuation.
