Answer:

Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei

Explanation:

Nuclear fusion is a process in which atomic nuclei are fused together to form heavier nuclei. ... Like fission, nuclear fusion can also transmute one element into another. For example, hydrogen nuclei fuse in stars to form the element helium.

Which statements about the reaction are true? Select all that apply. The reaction is exothermic The reaction is endothermic The

Digiron [165]

The statements true for the reaction are A, C, and E.

The potential energy diagram of the following reaction has been given:

$\rm CH_4\;+\;2\;O_2\;\rightarrow\;2\;H_2O\;+\;CO_2\;+\;891\;kJ$

The reaction has been given to form water and carbon dioxide, along with the release of 891 kJ of energy.

<h3>Statements for the reaction</h3>

The endothermic reaction is the type of reaction that absorbed the energy from the system, while exothermic reaction released energy in the system.

The given system has releasing 891 kJ of energy. Thus, it has been an exothermic reaction.

The equation has been representing the 891 kJ of energy as the product. Thus, it has been released in the reaction as product.

The potential energy graph has been representing that the energy of the reactant has been higher than the product.

Thus, the statements true for the reaction are A, C, and E.

In an equimolar mixture of o2 and n2, are the mass fractions equal?

nika2105 [10]

Answer:

Explanation:

The mass fraction is defined as:

$w_{i}=\frac{m_{i} }{m_{t} }$

where:

wi: mass fraction of the substance i
mi: mass of the substance i
mt: total mass of the system

<u><em>The mass fraction of two substances (A and B), will be the same, ONLY if the mass of the substance A (mA) is the same as the mass of the substance B (mB).</em></u>

An equimolar mixutre of O2 and N2 has the same amount of moles of oxygen and nitrogen, just to give an example let's say that the system has 1 mole of O2 and 1 mole of N2. Then using the molecuar weigth of each of them we can calculate the mass:

mA= 1 mole of O2 * 16 g/1mol = 16 g

mB=1 mole of N2 *28 g/1mol=28 g

As mA≠mB then the mass fractions are not equal, so the answear is NO.

Calculate the molar solubility of CaF2 at 25°C in a solution that is 0.010 M in Ca(NO3)2. The Ksp for CaF2 is 3.9 x 10-11.

madreJ [45]

Answer:

$Molar \ solubility=3.12x10^{-5}M$

Explanation:

Hello,

In this case, for the dissociation of calcium fluoride:

$CaF_2(s)\rightleftharpoons Ca^{2+}+2F^-$

The equilibrium expression is:

$Ksp=[Ca^{2+}][F^-]^2$

In such a way, via the ICE procedure, including an initial concentration of calcium of 0.01 M (due to the calcium nitrate solution), the reaction extent $x$ is computed as follows:

$3.9x10^{-11}=(0.01+x)(2*x)^2\\\\x=0.0000312M$

Thus, the molar solubility equals the reaction extent $x$ , therefore:

$Molar \ solubility=3.12x10^{-5}M$

Regards.
