Sodium Hydroxide is highly Basic
You know from looking at the molecular formula<span> that one </span>molecule<span> of </span>H2SO4<span> contains 2 </span>atoms<span> of hydrogen, 1 atom of sulfur and 4 </span>atoms<span> of oxygen.</span>
The amount of birds nests depends on whether or not the trees have more or less leaves.
The independent should be the trees/leaves.
The dependent variable should be the birds nests.
Hope this helped ^-^
The relationship between the number of visible spectral lines are identical for atoms .However they have unique wavelengths.
Option B
<u>
Explanation:</u>
A spectrum is a range of frequencies or a range of wavelengths. The photon energy of the emitted photon is equal to the difference between two states. For every atom there are quite many electron transitions and each has a energy difference.
This difference in wavelength causes spectrum .As each element emission spectrum is unique because each atom has different energy and causes uniqueness in the emission spectrum . Hence, due to the difference in energy it emits different wavelengths.
Answer:
A. the pressure decrease
Explanation:
pressure decreases when the surface area over which a force is applied increases. pressure increases when the surface area over which force is applied decreases.
