Red arrows represent the movement of the mantle due to convection. Black arrows represent the movement of the plates due to gravity. Scientists think that this transfer of thermal energy from core to mantle causes convection in the mantle.
Answer:
13.1dm³
Explanation:
Given parameters:
Pressure of gas = 880mmHg
760mmHg = 1 atm
880mmHg will give 1.16atm
Temperature = 303k
Mass of gas = 26.9g
Molar mass of CO₂ = 12 + 2(32) = 44g/mol
Number of moles = mass/molar mass = 26.9/44 = 0.61mole
Unknown:
Volume of the sample = ?
Solution:
To solve this problem, we use the ideal gas equation:
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹k⁻¹
T is the temperature
V = 
= 
= 13.1dm³
Answer:
In numerical order left to right, they are arranged by the number of protons in the nucleus of a single atom of each element
Dmitri Mendeleev was the creator and therefore organizer of the periodic table.
c.
Explanation:
I mainly think its c. from my point of view because as yoy can see they showed observations and explained certain information and they didnt conclude it as it's TRUE they said theories meaning its and Idea and something that is not fully proven happend.
