Option C: elements produce spectra with only few distinct lines.
The spectra are not continuos and are different for every element. This permits to identify elements.
Answer:
Monatomic ions are made up of only one atom per ion, whereas polyatomic ions are made up of numerous atoms per ion.
Explanation:
Answer:
Hydrogen
Explanation:
Hydrogen can never be central atom despite its low electronegativity
The change in temperature (ΔT) : 56.14 ° C
<h3>Further explanation</h3>
Given
Cereal energy = 235,000 J
mass of water = 1000 g
Required
the change in temperature (ΔT)
Solution
Heat can be formulated :
Q = m . c . ΔT
c = specific heat for water = 4.186 J / gram ° C
235000 = 1000 . 4.186 . ΔT

I think its B because if u increase the mass itll have more force which will increase the momentum
