Answer:

It's an atom

Explanation:

It can't be a molecule since it's only one element, the ion would've been Iodide (I-), and it's not a formula

Which describes the products created from fission reactions? Question 3 options:

Ipatiy [6.2K]

Answer: The correct answer is option A.

Explanation:

Nuclear fission reactions are a type of nuclear reactions in which larger nuclei breaks apart into two or more smaller fragment releasing alpha, gamma of beta particles.

There are 3 types of particles that can be released during this process:

1. Alpha particles: These particles are released when a nuclei undergoes alpha-decay process.

$_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\alpha$

2. Beta particles: These particles are released when a nuclei undergoes beta-minus decay process.

$_Z^A\textrm{X}\rightarrow _{Z+1}^{A}\textrm{Y}+_{-1}^0\beta$

3. Gamma radiations: these radiations are released when an unstable nuclei gives off excess energy by a process of spontaneous electromagnetic process.

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$

Hence, any of these particles can be released during the process of fission reaction with smaller atoms.

Therefore, the correct answer is option A.

An experiment produced 0.10 g CO2 with a volume of 0.056 L at STP. If the accepted density of CO2 at STP is 1.96 g/L, what is th

Mandarinka [93]

The experimental density of CO2 at STP is 0.10/0.056=1.78 g/L. The percent error equals to (1.96-1.78)/1.96*100%=9.18%. So the answer is 9.18%.

What is the oxidation state for the oxygen atom in na 2 o 2 ?

elixir [45]

$Na_{2}O_{2}

Na in compounds has oxidation number +1 only.

So, Na_{2}^{+1}O_{2}^{x}

2*(+1)+2x=0, x=-1.

Oxidation number oxygen in Na_{2}O_{2} is - 1.$
