A cluster of billions of atoms
that all have magnetic fields lined up in the same way is known as a
<span>The answer is letter C. Magnetic domain.</span>
<span>
The region around a magnet where the magnetic force is exerted is known as its
The answer is letter C. Magnetic field.</span>
The answer is 57.14%.
First we need to calculate molar mass of <span>NaHCO3. Molar mass is mass of 1 mole of a substance. It is the sum of relative atomic masses, which are masses of atoms of the elements.
Relative atomic mass of Na is 22.99 g
</span><span>Relative atomic mass of H is 1 g
</span><span>Relative atomic mass of C is 12.01 g
</span><span>Relative atomic mass of O is 16 g.
</span>
Molar mass of <span>NaHCO3 is:
22.99 g + 1 g + 12.01 g + 3 </span>· <span>16 g = 84 g
Now, mass of oxygen in </span><span>NaHCO3 is:
3 </span>· 16 g = 48 g
mass percent of oxygen in <span>NaHCO3:
48 g </span>÷ 84 g · 100% = 57.14%
Therefore, <span>the mass percent of oxygen in sodium bicarbonate is 57.14%.</span>
When considering atomic orbitals the only important information they really wanted to know is the size of the orbit, which was described by using quantum numbers.
Answer:
of carbon dioxide gas.
Explanation:
Average distance covered by Americans in a day=
1 day = 24 × 60 min = 1,440 min
Average distance covered by Americans in a minute=
Average mileage of the car = 20 miles/gal = 32.18 km/gal
1 mile = 1.609 km
20 miles = 20 × 1.609 km = 32.18 km
Volume of gasoline used in minute =
(1 L = 1000 mL)
Mass of 86,320.00 gallons of gasoline = m
Density of the gasoline = d =
1 kilogram of gasoline gives 3 kg of carbon dioxde gas .
Then 303,882.84649 kg of gasoline will give :
of carbon dioxide gas.
