Answer:

E = 26.4 ×10⁻²⁷ j

Explanation:

Given data:

Energy of energy =?

Frequency = 4×10⁷ Hz

Solution:

Formula:

E = hf

E = hf

E =  6.6  ×10⁻³⁴ m²Kg/s  . 4×10⁷ Hz

Hz = s⁻¹

j = m²Kg/s ²

E = 26.4 ×10⁻²⁷ j.

11. Which do you think is more important in forming personality---environment or heredity? Explain your answer.​
goldfiish [28.3K]

Answer:

I believe forming an environmental personality is more important than forming a hereditary personality. Why I said this is because of the people around out can change your personality, and sometimes if you're with the wrong people, it can go wrong, with your personality too. You could have been a nice person at some time, you bur you hung out with the wrong people and now you're just very inconsiderate. Another reason on why I believe forming an environmental personality is more important because of the fact that maybe you could've been born with a parent who has a bad personality. You could try your best to be nicer by the choice of people you choose to be friends with.

i hope this helped, im only in 7th

What is the difference between ionic and covalent bonding?
mr Goodwill [35]

In an ionic bond, one atom essentially donates an electron to stabilize the other atom. The atoms in an ionic bond have different electronegativity values from each other.

While in a covalent bond, the atoms are bound by shared electrons and the electronegativity values are the same.

Barium reacts with a polyatomic ion to form a compound with the general formula Ba3(X)2. What would be the most likely formula f
AfilCa [17]

Answer:

D. Na₃X

Explanation:

We have the neutral compound Ba₃(X)₂. <em>The total charge (zero) is equal to the sum of the charges of the ions times the number of ions in the molecule</em>.

3 × qBa + 2 × qX = 0

3 × (+2) + 2 × qX = 0

2 × qX = -6

qX = -3

If we have the cation Na⁺ and X³⁻, a neutral molecule would require 3 Na⁺ and 1 X³⁻. The resulting compound is Na₃X.
