Answer:
I think number4.Nuclear fusion reaction is not possible in earth
Nuclear fusion and nuclear fission both have common to temperatures over one million degrees Celsius are needed for the reaction to occur. Therefore, option 4 is correct.
What is nuclear fusion ?A reaction known as nuclear fusion occurs when two or more atomic nuclei fuse to create new atomic and subatomic particles. Energy is released or absorbed depending on how much mass there is between the reactants and products.
Nuclear reactions that involve fusion and fission both yield enormous quantities of energy that can be used to generate power.
The two heavy isotopes of hydrogen, deuterium and tritium, are the primary fuels used in nuclear fusion. Only 0.0153% of natural hydrogen is deuterium, which may be easily and cheaply produced from seawater. Lithium, which is also widely distributed in nature, can be used to create tritium.
Thus, option 4 is correct.

if a soda can is opened and left on a scale fot 24 hours how might the final mass change?
Answer: If a soda can is opened and left on a scale for 24 hours then the final mass change will decrease.
Explanation:
A soda can is like any other carbonated beverage that contains carbon dioxide dissolved under pressure. So, when a soda can is opened then there will occur a release in pressure due to which excess of carbon dioxide gas moves out of the solution in the form of bubbles.
When soda can is remained open for 24 hours then additional carbon dioxide moves slowly into the air. As a result, there will occur a decrease in final mass change.
Thus, we can conclude that if a soda can is opened and left on a scale for 24 hours then the final mass change will decrease.

Which property typically indicates strong intermolecular forces are present in a liquid? A) low heat of vaporization B) low critical temperature C) low vapor pressure D) low boiling point E) low melting point
Answer:
C) low vapor pressure
Explanation:
Vapor pressure refers to the pressure created by the vapor produced at a given temperature in a closed container. The pressure created as a result of the production of vapor above the liquid in a closed container. Vapor pressure works as the result of the force of the intermolecular force. When a liquid does evaporates easily it exemplifies that it has low vapor pressure. When the liquid evaporates easily and quickly, it exemplifies that it has high vapor pressure.
Statement that express the property of intermolecular forces that is been exhibited by liquid is C: low vapor pressure.
Intermolecular forces can be regarded as forces that is found between molecules. One of the property of this intermolecular forces can be seen in liquid which low vapour pressure.Vapour pressure is used in knowing the liquid to change into the gaseous state, it is at that point that liquid will reach i.e equilibrium pressure when in closed container.
Therefore, option C is correct.

Answer: The complete reaction is as follows.
[tex]^{14}_{7}N + ^{1}_{0}n \rightarrow ^{14}_{6}C + ^{1}_{1}H[/tex]
Explanation:
When nucleus of two or more atoms are bombarded together then it leads to the formation of new particles with new identity. This type of reaction are called nuclear reaction.
For example, [tex]^{14}_{7}N + ^{1}_{0}n \rightarrow ?C + ^{1}_{1}H[/tex]
Here, nitrogen atom when bombarded with a neutron then it is forming hydrogen and a carbon atom.
As total atomic mass on reactant side is (14 + 1) = 15
So, the atomic mass of carbon formed on product side is (15 - 1) = 14.
The number of protons holded by this carbon atom is (7 - 1) = 6.
Therefore, we can conclude that the complete reaction is as follows.
[tex]^{14}_{7}N + ^{1}_{0}n \rightarrow ^{14}_{6}C + ^{1}_{1}H[/tex]

Answer:
pH = 3.5
Explanation:
HCl is a strong acid, so we can use this little formula to find the pH of the solution:
pH = -log[H3O+]
(where H3O+ is the strong acid, HCl)
So we just plug in the molarity for the concentration of the acid...
pH = -log(0.00034)
Solve.
pH = 3.468521083

Identify a covalently bonded molecule in the reaction above that is a
REACTANT.
Answer: A covalently bonded molecule in the reaction
[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].
Explanation:
A bond formed by sharing of electrons between two or atoms is called a covalent bond.
For example, bromine is a group 17 element and it has 7 valence electrons. It needs one more electron to complete its octet.
So, when one bromine atom chemically combines with another bromine atom then sharing of electrons takes place which leads to the formation of [tex]Br_{2}[/tex] molecule.
Hence, in the equation [tex]K + Br_{2} \rightarrow KBr[/tex]; [tex]Br_{2}[/tex] reactant is a covalently bonded molecule. A covlent bond is formed by two or more non-metal atoms that chemically combine together.
In a chemical equation, reactants are written on the left side and products are written on right side.
Thus, we can conclude that a covalently bonded molecule in the reaction
[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].
Density measurements can be used to analyze mixtures. For example, the density of solid sand (without air spaces) is about 2.84 g/mL. The density of gold is 19.3 g/mL. If a 1.00 kg sample of sand containing some gold has a density of 3.10 g/mL (without air spaces), what is the percentage of gold in the sample
Answer:
Following are the responses to the given question:
Explanation:
Let S = solid sandy mass inside the blend
Let G = gold mass in such a blend
We search that percent G by mass
Mixture density = total blend mass / total blend volume = 3.10 g/mL
Mixture sum [tex]= S + G = 1 \ kg = 1000\ g[/tex]
Complete mixing volume = sand volume + gold volume volume
Complete mixing volume [tex]= (\frac{sand\ mass}{sand \ density}) + (\frac{gold\ mass}{gold \ density})[/tex]
Total mixture volume:
[tex]= (\frac{S}{2.84}) + (\frac{G}{19.3})\\\\ = \frac{(19.3 S + 2.84 G)}{54.812\ mL}[/tex]
[tex]\text{Mixture Density} = \frac{\text{mass mixture}}{\text{mixture volume}}[/tex]
[tex]= 3.10 \frac{g}{mL} \\\\ \to 3.10 = \frac{1000 \ g}{ \frac{(19.3 S + 2.84 G)}{ 54.812}}\\\\\to 19.3 S + 2.84 G = 17681[/tex]
When
[tex]S + G = 1000 \ g[/tex]
Solving equation:
[tex]\to 19.3 S + 2.84 G = 17 681\\\\\therefore \ S + G = 1000 \ g\\\\\to 19.3 S + 2.84 G = 17 681\\\\\to -2.84S -2.84 G = -2840\\\\----------------\\\\\to 16.46S = 14 841\\\\\to S = 901.7 g \ SanD[/tex]
When
[tex]\to S+ G = 1000\\\\\to G = 1000 - 901.7\ g\\\to G = 98.3 g \ GOLD[/tex]

Explain why the CO2 from your breath had the effect on the pH of water that it did. Explain any anomalies in your experiment.
Explanation:
As atmospheric CO2 levels increase due to anthropogenic causes, dissolved CO2 also increases, which in turn decreases the pH of water. When water becomes saturated with CO2, it not only reduces the ocean's pH, but depletes the calcium carbonate sources as well ³⁵
A student combines a solution of NaCl(aq) with a solution of AgNO3(aq), and a precipitate forms. Assume that 50.0mL of 1.0MNaCl(aq) and 50.0mL of 1.0MAgNO3(aq) were combined. According to the balanced equation, if 50.0mL of 2.0MNaCl(aq) and 50.0mL of 1.0MAgNO3(aq) were combined, the amount of precipitate formed would:_________
Answer:
Based on the given information, the balanced equation is:
NaCl + AgNO3 = AgCl + NaNO3
Now the moles present in 50 ml of 1M NaCl is,
= 50 * 1/1000 mole = 0.05 mole
And the moles present in 50 ml of 1 M AgNO3 is,
= 50*1/1000 mole = 0.05 mole
Therefore, 0.05 mole of NaCl combines with 0.05 mole of AgNO3 to precipitate 0.05 mole of AgCl.
Now in the second case, to balance the chemical equation, 50 ml of 2 M NaCl combines with 50 ml of 1 M AgNO3. So, the moles present in 50 ml of 2 M NaCl will be,
= 50*2/1000 mole = 0.1 mole
However, the amount of AgNO3 in the second case is not changing, therefore, the amount of AgCl precipitated will be,
= 0.1 - 0.05 = 0.05 mole
Therefore, the amount of precipitate would not change as there is no change in the amount of AgNO3.
The amount of precipitate (NaCl) formed would be 0.05 mole
From the question,
We are to determine the amount of precipitate formed.
First, we will write the balanced chemical equation for the reaction
The balanced chemical equation for the reaction is
NaCl(aq) + AgNO₃(aq) → AgCl(s) + NaNO₃(aq)
This means
1 mole of NaCl reacts with 1 mole of AgNO₃ to produce 1 mole of AgCl and 1 mole of NaNO₃
The precipitate formed is AgCl
Now, we will determine the number of moles of each reactant present
For NaClVolume = 50.0 mL = 0.05 L
Concentration = 2.0 M
Using the formula
Number of moles = Concentration × Volume
∴ Number of moles of NaCl present = 2.0 × 0.05
Number of moles of NaCl present = 0.10 mole
For AgNO₃Volume = 50.0 mL = 0.05 L
Concentration = 1.0 M
∴ Number of moles of AgNO₃present = 1.0 × 0.05
Number of moles of AgNO₃ present = 0.05 mole
Since
1 mole of NaCl reacts with 1 mole of AgNO₃ to produce 1 mole of AgCl
Then,
0.05 mole of NaCl will react with 0.05 mole of AgNO₃ to produce 0.05 mole of AgCl
∴ The number of moles of NaCl formed is 0.05 mole
Hence, the amount of precipitate (NaCl) formed would be 0.05 mole
