Answer:
False
Explanation:
sea floor spreading is not consistent at all mid ocean ridges.
Answer:
34.28 L ( 1.5*22.4 L)
Explanation:
Calculation of the moles of aluminum as:-
Mass = 55 g
Molar mass of aluminum = 26.981539 g/mol
The formula for the calculation of moles is shown below:
Thus,

According to the reaction:-

4 moles of aluminum react with 3 moles of oxygen gas
1 mole of aluminum react with
moles of oxygen gas
2.0384 moles of aluminum react with
moles of oxygen gas
Moles of oxygen gas = 1.5288 moles
At STP,
Pressure = 1 atm
Temperature = 273.15 K
Using ideal gas equation as:

where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
1 atm × V = 1.5288 mol × 0.0821 L.atm/K.mol × 273.15 K
⇒V = 34.28 L ( 1.5*22.4 L)
Answer:You can reduce our carbon footprints by using renewable energy,
Explanation:
Answer:
C) Highly reactive
Explanation:
An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion
electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal).
