3 0

Answer:

since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).

Romashka [77]

<u>Answer:</u> The nuclear fission reaction of U-234.043 is written below.

<u>Explanation:</u>

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given fission reaction:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{A}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

<u>To calculate A:</u>

Total mass on reactant side = total mass on product side

234.043 = 137.159 + A + 3(1.0087)

A = 93.858

Now, the chemical equation becomes:

^{234.043}_{92}\textrm{U}\rightarrow ^{137.159}_{54}\textrm{Xe}+^{93.858}_{38}\textrm{Sr}+3^{1.0087}_0\textrm{n}+180MeV

Hence, the nuclear fission reaction of U-234.043 is written above.

What volume of sulfur trioxide would be produced by reaction of 2.56 L of oxygen with excess sulfur at STP?
shepuryov [24]
The balanced chemical reaction would be :

S + O2 = SO2
2SO2 + O2 = 2SO3

We are given the amount of oxygen to be used in the reaction. This will be the starting value in the calculations. We do as follows:

2.56 L O2 ( 1 mol / 22.4 L) ( 1 mol SO2 / 1 mol O2 ) ( 2 mol SO3 / 2 mol SO2 ) 22.4 L / 1 mol =  2.56 mol SO3

What is the density of 10cm^3 volume of water that has a mass of 10g?
prisoha [69]

Answer:

The answer is

<h2>1.0 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 10 g

volume = 10 cm³

It's density is

density =  \frac{10}{10}  = 1 \\

We have the final answer as

<h3>1.0 g/cm³</h3>

Hope this helps you
