Answer:
No 1 is fission
while no 2 is fusion
Fission is splitting on nucleus while fusion is forming heavier nucleus with nuclei
The kind of nuclear reaction that occurs in the following reactions are:
i. nuclear fission
ii. nuclear fusion.
What is a nuclear reaction?Nuclear reactions are that reactions in which a nucleus or nuclei collides with subatomic particles to form another, different nucleus. There are two types of collisions. Nuclear fission and nuclear fusion.
Nuclear fission is a process when large nuclei split and create small, numerous nuclei. It happens due to the instability of an atom. It split into two daughter nuclei.
Nuclear fusion is a process in which two or more small nuclei combine to create a large, heavy nucleus. The process releases a large amount of energy or can be absorbed.
Thus, the processes are i. nuclear fission
ii. nuclear fusion.

If 125 mL of 0.56 MH2SO4, is diluted to a volume of 0.250 L, what is the molarity of the resulting solution?
Answers
Answer:
0.28M H2SO4
Explanation:
The molarity of a solution is defined as the ratio between the moles of the solute (In this case, H2SO4) and its volume in liters.
In the problem, the volume of the solution is increased from 125mL to 250mL. That means the solution is diluted:
250mL / 125mL = 2 times.
As the solution is diluted 2 times, the concentration is decreased in 2, that is:
0.56M / 2 =

The new planet has an atmosphere that is 96% carbon dioxide with only trace amounts of oxygen. What could humans do to make enough oxygen to survive? Explain your answer.
Answers
Answer:
See Explanation
Explanation:
A biosphere is a zone of life found on earth. Since the artificial biosphere has all the elements that support and sustain human life, then there must also be soil in the artificial biosphere.
If that is the case, then we can engage in massive tree planting. Trees take in carbon dioxide and release oxygen. Hence if a large number of trees are planted all over the artificial biosphere, the trees will eventually produce large enough oxygen to support human life overtime.

31. A mixture with sand, pink sugar and water would be best separated using
Answers
Answer:
Filtration and evaporation
Explanation:
A mixture of sand, pink sugar and water can be separated by filtration and evaporation.
The pink sugar is already dissolved in the water but the sand remains undissolved in the water hence it can be filtered off. The filtrate now contains the sugar.
The sugar is obtained from the filtrate by evaporation of the solution to yield the solid pink sugar and steam which can be condensed again to give liquid water.
Why do you think certain countries favored military solutions to the great depression while other contries did not
Answers
Answer:
The answer is below
Explanation:
Certain countries like Germany under Adolf Hitler favored military solutions to the great depression because the government felt that having a mass production of military weapons and recruitment of unemployed people or citizens into the army would change the dire situation.
On the other hand, countries like the United States did not favor the military solutions but instead choose the NEW DEAL under Franklin D Roosevelt; the reason could be linked to their democratic culture, the isolation belief tendency.

i would appreciate it if someone could show me the net ionization reaction for the following equation:
CaCl2(aq) + 2NaHCO3 -> CaCO3 + 2NaCl + CO2 + H2O
thanks in advance!!
Answers
Answer:
Deduce the balanced chemical equation:
CaCO3(s) + 2HCl(aq) > CaCl2 + H2O(l) + CO2(g)
2. Write as ionic species:
Ca2+(aq) + CO3 2- (aq) + 2H+ + 2Cl- > Ca2+(aq)+ 2Cl-(aq) + H2O(l) + CO2(g)
3. Identify ions on the right that also appear on the left, and eliminate them. (As Robert Cruikshank says, these are known as ’spectator ions’ and take no overall part in the reaction):
CO3 2- (aq) + 2H+(aq) > H2O(l) + CO2(g)
This is the balanced ionic equation.
A toy balloon is filled to 135 mL at a temperature of 22.5 °C (295.5 K). What temperature in Kelvin does it need to be heated to expand to 250 mL?
Answers
Answer:
T2 = 547.2K
Explanation:
Given:
V1 = 135 ml. V2 = 250 ml
T1 = 295.5K. T2 = ?
Using Charles's law and solving for T2,
V1/T1 = V2/T2
T2 = (V2/V1)T1
= (250 ml/135 ml)(295.5K)
= 547.2K (or 273.2°C)

What effect does the Earth's surface have on solar radiation?
Answers
Answer:
Thus, the proportion of Earth's surface that is covered by ice and snow affects how much of the Sun's solar radiation is absorbed, warming the planet, or reflected. Therefore, snow and ice which are covered in soot from pollution no longer reflect sunlight, but absorb it and so melting increases.
Answer:
Half of the solar radiation is absorbed and converted to infrared (heat).

How many grams of Mg would be needed to react with 6.0 moles HCl?
Answers
Answer:
72g
Explanation:
The balanced equation of the reaction between Magnesium (Mg) and hydrochloric acid (HCl):
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
Based on this equation, 1 mole of Mg needs to react with 2 moles of HCl.
Hence, 6 moles of HCl will need to react with 6 × ½ = 3 moles of Mg.
Using the formula; mole = mass/molar mass
Molar mass of Mg = 24g/mol
3 = mass/24
mass = 72g.

N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
[tex]n = \frac{1.204 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.02[/tex]

How many moles of KCl are produce when 61.5 g of KClO3 are decomposed?
Answers
Answer:
0.502mol
Explanation:
The balanced chemical equation of the reaction described in this question is as follows:
2KClO3 → 2KCl+ 3O2
According to the equation above, 2 moles of KClO3 will produce 2 moles of KCl.
Using mole = mass/molar mass to convert mass of KClO3 to moles
Molar mass of KClO3 = 39 + 35.5 + 16(3)
= 39 + 35.5 + 48
= 122.5g/mol
mole = 61.5 g ÷ 122.5g/mol
mole = 0.502mol
Since 2 moles of KClO3 will decompose to produce 2 moles of KCl.
0.502 mol of KClO3 will decompose to produce 0.502 × 2/2
= 0.502mol of KCl.
