Answer:
The answer to your question is below
Explanation:
Metals lose electrons and Nonmetals gain them.
a. Ra is in group IIA it will lose electrons, the ion will be Ra⁺²
b. Br is in group VIIA it will gain electrons, the ion will be Br⁻¹
c. In is in group IIIA it will lose electrons, the ion will be In⁺³
d. Te is in group VIA it will gain electrons, the ion will be Te⁻²
e. Ca is in group IIA it will lose electrons, the ion will be Ca⁺²
f. As is in group VA it will gain electrons, the ion will be As⁻³
g. Al is in group IIlA it will lose electrons, the ion will be Al⁺³
h. Rb is in group IA it will lose electrons, the ion will be Rb⁺¹
Answer:
Empirical formula of C₈H₈ = CH
Explanation:
Data Given:
Molecular Formula = C₈H₈
Empirical Formula = ?
Solution
Empirical Formula:
Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.
So,
tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule
C₈H₈ Consist of Carbon (C), and Hydrogen (H)
Now
Look at the ratio of these two atoms in the compound
C : H
8 : 8
Divide the ratio by two to get simplest ratio
C : H
8/8 : 8/8
1 : 1
So for the empirical formula is the simplest ratio of carbon to hydrogen 1 : 1
So the empirical formula will be
Empirical formula of C₈H₈ = CH
I think it’s A but I’m not sure, if it’s wrong I’m sorry
Answer:
Explanation:
Uma declaração verdade é identificada pelo de ela afirmar a verdade diferente das outras opções
Jamuuj ExpertThe energy of a wave is directly proportional to the square of the waves amplitude. Therefore, E = A² where A is the amplitude. This therefore means when the amplitude of a wave is doubled the energy will be quadrupled, when the amplitude is tripled the energy increases by a nine fold and so on.Thus, in this case if the energy is 4J, then the amplitude will be √4 = 2 .
