Benzene is used for pesticides and detergents. It is also used for other things besides these.
Answer:
- Nucleus Function - Controls and regulates the activity of the cell.
- Ribosome builds proteins.
- A vesicle structure is kinda like a sac filled with a fluid of sorts.
- Rough ER has ribosomes attached to the cytoplasmic side of the membrane.
- Golgi apparatus kinda looks like a "stack of peta bread"
- Golgi apparatus functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.
- The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.
- The mitochondria produced energy/ATP
- Mitochondria have a double membrane arrangement that separates the organelle into four distinct compartments
- The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton
Answer:
Explanation to the following question is as follows;
Explanation:
Any phenomenon that would have the potential to cause severe death or property damage is considered a danger. When the potential for devastation is realised, a hazard becomes a disaster. All catastrophes are risks, but not all risks are catastrophes. Hazards do not always result in devastation.
The number of oxygen atoms is in 5.00 g of sample of sodium dichromate, Na₂Cr₂O₇ is 1.125 x 10²³ atoms.
<h3>What is sodium dichromate?</h3>
Sodium dichromate is an inorganic compound. It is sued in tanning and mental illness.
The molar mass of sodium = 23 gm
The molar mass of Cr = 51.99 gm
The molar mass of oxygen = 16 gm
Molar mass of Na₂Cr₂O₇ = 2(23) + 2(51.99) + 7(16) = 261.98 gm
Number of moles in 7 gm = mass / molar mass = 7 / 261.98 = 0.0267 moles
1 mole of Na₂Cr₂O₇ contains 7 moles of oxygen, therefore:
The number of moles of oxygen in 0.0267 moles = 0.0267 x 7 = 0.1869 moles
Thus, the number of atoms = 0.1869 x 6.02 x 10^23 = 1.125 x 10²³ atoms.
