Answer: It is Gamma ray

Answer:

C. gamma ray

(Photo for proof at the bottom.)

Explanation:

A gamma ray is a type of radiation that occurs when an unstable nucleus emits a photon, the smallest unit of light. A photon has no mass or charge. Atomic and mass numbers are written based on the mass of the atom. But since no mass is lost when a photon is emitted, writing the emission of it isn't necessary.

Here's a photo of Edge, good luck.

9.86 x 10²⁸ O-atoms require what volume (L) N₂O₂ at STP?
jolli1 [7]
First, we use avogadro's number to convert atoms into moles. Then, relate the number of moles from elemental to the compound. Lastly, we use conditions at STP to calculate the volume. We do as follows:

<span>9.86 x 10²⁸ O-atoms ( 1 mol / 6.022x10^23 atoms O) ( 1 mol N2O2 / 2 mol O ) ( 22.4 L / 1 mol ) = 1833809.37 L needed</span>

What is the molarity of a NaOH solution if 28.2 mL of a 0.355 M H2SO4 solution is required to neutralize a 25.0-mL sample of the
Verdich [7]

Answer:

[NaOH} = 0.4 M

Explanation:

In a reaction of neutralization, we determine the equivalence point of the titration. In this case, we have a strong base and a strong acid.

(H₂SO₄, is considered strong, but the first deprotonation is weak)

2NaOH  +  H₂SO₄  →  Na₂SO₄  + 2H₂O

As we have 2 protons in the acid, we need 2 OH⁻ from the base to form 2 molecules of water.

In the equivalence point we know mmoles of base = mmoles of acid

Let's finish the excersise with the formula

25 mL . M NaOH = 28.2 mL  .  0.355M

M NaOH = (28.2 mL  .  0.355M) / 25 mL → 0.400
