Answer:
Actinides
Explanation:
They are defined as "any of the series of fifteen metallic elements from actinium (atomic number 89) to lawrencium (atomic number 103) in the periodic table. They are all radioactive, the heavier members being extremely unstable and not of natural occurrence"
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
A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely. <span>The molarity of the sodium hydroxide solution cannot be determined accurately because s</span>olid sodium hydroxide is highly hygroscopic (absorbs water from the air) and cannot be accurately weighed. Sodium hydroxide form sodium carbonate because it absorbs carbon
dioxide from the air.
Answer:
They all end up in the oceon
Explanation:
Answer:
27.98g/mol
Explanation:
Using ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
T = temperature (K)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
According to the information given:
V = 2.5L
P = 1.4 atm
T = 282K
n = ?
Using PV = nRT
n = PV/RT
n = 1.4 × 2.5/0.0821 × 282
n = 3.5/23.1522
n = 0.151mol
Using the formula to calculate molar mass of the elemental gas:
mole = mass/molar mass
Molar mass = mass/mole
Molar mass = 4.23g ÷ 0.151mol
Molar mass = 27.98g/mol
