Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Explanation:
Answer:
Dilute the mixture with distilled water
Explanation:
3% solution: mix 1 part of 35% food grade hydrogen peroxide with 11 parts distilled water. Ratio is 1 to 11.
Answer:
V = 0.0007678398L
Explanation:
Given parameters:
Number of moles of gas = 3.43moles
Temperature = 273k
pressure = 100kPa = 100000Pa
Unknown:
Volume of gas = ?
Solution
The gas is at standard temperature and pressure, this implies we can use the ideal gas equation to solve for the unknown.
Mathematically, the law is expressed as:
PV = nRT
The unknown here is the Volume, V. We know the other parameters.
P = pressure on the gas
n = number of moles
R = gas constant=0.082
T = temperature
now, we have to make V the subject of the expression:
V = 
V = 
V = 0.0007678398L
B,because it seems like the most active answer outta the rest
Answer:
Concentration = 0.14 M
Explanation:
Given data:
Volume of base = 19.62 mL
Molarity of base = 0.341 M
Volume of acid = 25.00 mL
Molarity of acids = ?
Solution:
Number of moles of base = Molarity × volume in litter
Number of moles = 0.341 mol/L × 0.02 L
Number of moles = 0.007 mol
Concentration of acid:
Concentration = 1/2 (0.007 mol) / 25 mL × 10⁻³ L/mL
Concentration = 0.0035 mol / 25 × 10⁻³ L
Concentration = 1.4 × 10⁻¹ M
Concentration = 0.14 M
