A clastic sedimentary rock is
composed of silicate minerals and rock fragments. They are transported by
moving fluids such as sedimentation due to gravity and are deposited in the
area where it stays. They are composed mostly of feldspar, quartz, rock
(lithic) fragments, clay minerals and mica.
Answer:
True
Step-by-step explanation:
An ionic bond is the attraction between a cation and an anion.
If there is no cation or anion, there is no ionic bond.
Answer:
2.355atm
Explanation:
To get the pressure of helium, we need to get the mole fraction of helium.
The total mole fraction for any mixture of gases equals 1. Hence to get the mole fraction of the helium, we simply subtract the addition of the mole fractions of neon and argon from 1.
This means - 1 - 0.47 - 0.23 = 0.3
Now, to get the pressure of the helium gas, we simply multiply the total pressure by 0.3. This is 0.3 * 7.85 = 2.355 atm
Answer: 2800 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
Given mass = 5 kg = 5000 g
1 mole of 
produces = 1 mole of 
50 moles of produces =
of
Mass of 
2800 g of is produced from 5.0 kg of limestone.
