Answer:
Yes, they are.
Explanation:
The United States is one of these nuclear superpowers, making the ethical issues associated with these weapons critical and relevant. ... Most research across disciplines unanimously agrees that it is immoral to detonate an atomic weapon due to both short and long-term catastrophic effects.
In fact, some scholars have concluded that it is therefore morally wrong to act in ways that produce these outcomes, which means it is morally wrong to engage in nuclear warfare.
Answer:
NO not at all.
Explanation:
After reading the accounts of people who survived the bomb in Hiroshima and Nagasaki in 1945 during World War II, I was horrified just reading the testimonies. Almost every single survivor described the skinless and bloated bodies they had seen everywhere. Inosuke Hayasaki, a surivor of the bombing, noticed one of his classmates, among many other citizens, pleading for water. When he tried listening for his heartbeat, his "skin slipped right off". Bombs are used in war so the other side will surrender. Bombs are aimed at "enemies" as if every being is an object to destroy. So no, bombing----let alone nuclear bombing----is ethical.

Consider the following chemical reaction:
HF + NaOH - NaF + H20
Energy must be invested in order for the reaction to proceed.
What bonds must be broken in order for the reaction to proceed.
Select ALL that apply.
A. An ionic bond between sodium and hydroxide.
B. An ionic bond between sodium and fluorine.
C. A covalent bond between sodiume and fluorine.
D. An ionic bond between hydrogen and fluorine.
DE. A covalent bond between hydrogen and fluorine.
DE A covalent bond between hydrogen and oxygen
Answer: The correct options are A and E
Explanation:
A chemical reaction is defined as the reaction in which two or more chemical substances react to form two or more different chemical substances.
A new substance (product) is formed in a chemical reaction when the bonds between the reactants are broken so that the new bonds between the products can be formed.
For a given chemical reaction:
[tex]HF+NaOH\rightarrow NaF+H_2O[/tex]
Here,
HF is a covalent compound as sharing of electrons take place between hydrogen and fluorine atom
NaOH is an ionic compound as a complete transfer of electrons occurs from sodium to hydroxide.
Thus, to form the products, an ionic bond between sodium and hydroxide must be broken coupled with a covalent bond between hydrogen and fluorine.
Hence, the correct options are A and E
How did reducing the number of
decomposers affect the amount of carbon
dioxide in the ecosystem?
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.

When 11.2 liters of hydrogen gas is made by adding zinc to sulfuric acid, what mass
of zinc is needed?
Zn + H2SO4 -> H2 + ZnSO4
32.7 g Zn
Explanation:
First convert the amount of gas into moles:
11.2 L H2 × (1 mol H2/22.4 L H2) = 0.500 mol H2
Then use the molar ratio to find the amount of zinc necessary to produce the amount of gas above:
0.500 mol H2 × (1 mol Zn/1 mol H2)
= 0.500 mol Zn
Now use the molar mass of zinc to find the number of grams of zinc for the reaction to occur:
0.500 mol Zn × (65.38 g Zn/1 mol Zn)
= 32.7 g Zn

14. Each beaker shown to the right contains iron and an
acid. In which beaker will the iron dissolve the fastest
and why?
a. Beaker A because of a higher concentration level.
b. Beaker A because of increased surface area.
C. Beaker B because of a higher concentration level.
d. Beaker B because of increased surface area.
The question is incomplete, the complete question is attached in the image below:
Answer: The correct option is D) Beaker B because of the increased surface area.
Explanation:
A solution consists of solute and solvent.
A solute is defined as a component that is present in a smaller proportion while a solvent is defined as a component that is present in a larger proportion.
Solubility is defined as the amount of solute that can be dissolved in a given amount of solvent to form a solution.
Solubility of a substance depends on a few factors:
Surface areaMolecular sizeTemperatureStirring effectFor the given images,
Beaker A has a large block of iron rod and Beaker B has iron shards.
The smaller molecular size of a substance increases its surface area and thus, increases the solubility.
Hence, the correct option is D) Beaker B because of the increased surface area.

Q1.what is irragation
Answer:
Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
Answer: The watering of crop plants in regular intervals is known as irrigation. ... Weeds are unwanted plants thet grows with the crop plants. Weeding means to remove those plants. It is done manually or by machine. Using khurpi it is done manually and using seed drill it is done by machine.
Explanation:
Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected.

What is nuclear fission?Nuclear fission is a kind of radioactive decay reaction in which an unstable nuclei of an atom will split into smaller stable nuclei by the emission of lots of energy.
Gamma emitter is used inside the human body to trace the information that assists in making a diagnosis by the help of medication.To treat cancer patient high energetic rays like x-rays, gamma-rays are used.Formation of isotope of helium from two different isotopes of hydrogen is an example of nuclear fussion reaction.Hence in nuclear fission a large radioactive atom breaks into smaller atoms, producing nuclear energy.

. Calculate the pH and the pOH of each of the following solutions at 25 °C for which the substances ionize completely:
(a) 0.200 M HCl
(b) 0.0143 M NaOH
(c) 3.0 M HNO3
(d) 0.0031 M Ca(OH)2
Based on the molarity of the solutions;
For 0.200 M HCl; pH = 0.699, pOH = 13.301For 0.0143 M NaOH; pOH = 1.845, pH = 12.16For 3.0 M HNO3; pH = -0.4771, poH = 14.4771For 0.0031 M Ca(OH)2; pOH = 2.21, pH = 11.79What pHand pOH?pH is the negative logarithm to base ten of the hydrogen ions concentration of a solution.
pH = -log[H+]pOH is the negative logarithm to base ten of the hydroxide ions concentration.
pOH = -log[OH-]Also;
pH + pOH = 14For HCl:
pH = -log [H3O+]
pH =-log (0.200)
pH = 0.699
Then;
poH= 14-0.699
pOH = 13.301
For NaOH:
pOH= -log [OH-]
= -log (0.0143)
pOH = 1.845
Then;
pH= 14-poH
= 14- 1.845
pH = 12.16
For HNO3:
pH= -log[H3O+]
=-log(3.0)
= -0.4771
Then;
pOH = 14-9-0.4771
pOH = 14.4771
For [Ca(OH)2]
molarity = 0.0031M
2 moles of OH- are produced
[OH-]= 2 × 0.0031
[OH-] = 0.0062M
pOH = - log[OH-]
=-log(0.0062)
=-log(6.2x10-3)
=-(-2.21)
pOH = 2.21
Then;
pH =14-2.21
pH =11.79

How many carbon atoms are there in .500 mol of CO2?
Answer: There are [tex]3.011 \times 10^{23}[/tex] atoms present in 0.500 mol of [tex]CO_{2}[/tex].
Explanation:
According to the mole concept, there are [tex]6.022 \times 10^{23}[/tex] atoms present in 1 mole of a substance.
In a molecule of [tex]CO_{2}[/tex] there is only one carbon atom present. Therefore, number of carbon atoms present in 0.500 mol of [tex]CO_{2}[/tex] are as follows.
[tex]1 \times 0.500 \times 6.022 \times 10^{23}\\= 3.011 \times 10^{23}[/tex]
Thus, we can conclude that there are [tex]3.011 \times 10^{23}[/tex] atoms present in 0.500 mol of [tex]CO_{2}[/tex].
