Answer:

The fuel for nuclear fusion is often uranium
Nuclear fusion is used to generate electricity at nuclear power plants

Explanation:

The most common nuclear fuel is made up of fissile elements such as Uranium, Neptunium, Plutonium, Americium and Curium, which are fissionable elements, which is when its nucleus is capable of undergoing a fission with neutrons free of any energy.

Nuclear fission can be used both for warlike purposes, as in the construction of atomic bombs, as well as for pacifist purposes, in the construction of reactors for the production of electrical energy.

What is the empirical formula of the compound that is 25.3% magnesium and 74.7% chlorine

Margarita [4]

Answer: $MgCl_2$

Explanation:

25.3% Mg

74.7% Cl

First step: change % to g

25.3g Mg

74.7g Cl

Second step: calculate g/mol of each compound. You can do this by using the atomic mass.

$25.3gMg(\frac{1mol}{24.30g})=1.04mol$

$74.7gCl(\frac{1mol}{35.45g} )=2.11mol$

Third step: determine the lowest number and divide everything by it. Of the result, extract whole number only.

$Mg=\frac{1.04}{1.04} =1$

$Cl=\frac{2.11}{1.04}=2$

Fourth step: Write each compound with their respective number below.

This empirical formula should be: $MgCl_2$

A compound has the formula C8H8 and does not contain any double or triple bonds. All the carbon atoms are chemically identical a

Ann [662]

Answer:

<h3>There's no way for C8H8 to exist without double bonds. To fulfill the rule of the octet, four bonds must be formed by each carbon. This can only be done in C8H8 through the formation of double bonds.</h3>

A 25.0 mL sample of an acetic acid solution is titrated with a 0.175 M NaOH solution. The equivalence point is reached when 37.5

Soloha48 [4]

This is all i know
First of all, let's write the equation of the reaction.
CH₃COOH + NaOH ⇒ CH₃COONa + H₂O
The formula to be used here is CaVa/CbVb = na/nb
where Ca is the concentration of the acid (?)
Cb is the concentration of the base (0.175M)
Va is the volume of the acid (25 mL)
Vb is the volume of the base (37.5 mL)
na is the number of moles of acid (1)
nb is the number of moles of base (1)
Ca × 25/0.175 × 37.5 = 1/1
Ca = 0.175 × 37.5 × 1 /25 ×1
Ca = 0.263 M
The concentration of the acid in the sample was 0.263 M
