Answer: The main purpose of any warhead is to inflict damage on the target. The way the damage is caused may vary with different types of warheads, but in the most general sense, damage is caused by the transfer of energy from the warhead to the target. The energy is typically mechanical in nature and takes the form of a shock wave or the kinetic energy of fragments. In either case, a large amount of energy must be released. For many warheads that energy is stored in the form of chemical explosives.
Explosive Reactions
There are many chemical reactions that will release energy. These are known as exothermic reactions. If the reaction proceeds slowly, the released energy will be dissipated and there will be few noticeable effects other than an increase in temperature. On the other hand, if the reaction proceeds very rapidly, then the energy will not be dissipated. Thus, a great quantity of energy can be deposited into a relatively small volume, then manifest itself by a rapid expansion of hot gases, which in turn can create a shock wave or propel fragments outwards at high speed. Chemical explosions may be distinguished from other exothermic reactions by the extreme rapidity of their reactions. In addition to the violent release of energy, chemical explosions must provide a means to transfer the energy into mechanical work. This is accomplished by expanding product gases from the reaction. If no gases are produced, then the energy will remain in the products as heat.
Most chemical explosions involve a limited set of simple reactions, all of which involve oxidation (reaction with oxygen). A relatively easy way to balance chemical explosive equations is to assume that the following partial reactions take place to their maximum extent (meaning one of the reactants is totally consumed) and in order of precedence:

In an ecosystem, 20 percent of the protein consumed by humans around the world is fish.
What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the ecosystem .Living organisms also influence the quantity of biomass which is present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Determine the number of grams in each of the quantities
1.39.0 x 1024 molecules Cl2
Mass of Cl₂ : 164.01 g
Further explanationA mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :
[tex]\tt n=\dfrac{N}{No}\\\\n=\dfrac{1.39.10^{24}}{6.02.10^{23}}\\\\n=2.31[/tex]

It takes 7.21 1019 J of energy to remove an electron from an iron atom. What is the maximum wavelength of light that can do this
Answer:
2.75 × 10^-45 m
Explanation:
From;
E= hc/wavelength
h= Plank's constant= 6.6 × 10^-34 Js
c= speed of light=3× 10^8 ms-1
Wavelength = 6.6 × 10^-34 × 3× 10^8/7.21 × 10^19
Wavelength= 2.75 × 10^-45 m

Explanation:
if there are 365 grams of NaCl, how many grams of sodium are there?
Answer: Molar mass is the amount grams that one mole weighs.
Explanation: You need to find the molar mass of NaCl which is the same as the amu on the periodic table in grams. So it is 22.99(Na) + 35.45(Cl) = 58.44
You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.
Finally, using the periodic table, again, you see that the molar mass of Na is 22.99.
Then using stoichiometry, you can find the grams of sodium.
100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Na)/ 1 mol (NaCl) * 22.99 (g of Na)/ 1 mol (Na)
which equals 39.339435 g of Na.
If you need to maintain significant figures the answer will be 40.

Suppose you pour a glass of ice water and set it on the kitchen table. After a few minutes, the outside of the glass will be covered with drops of water. Why did this happen?
For condensation to take place there should be noticeable difference between the temperature of the system and the atmosphere. Thus condensation is the reason for clinging of water particles to the side of the glass.
What is condensation?Condensation is a process in which the vapor state converts to liquid state. Condensation is the reverse process of evaporation. Condensation occur at dew point. Dew point is the temperature at which condensation starts.
When the hot air particles collides with the surface of the glass having ice water, then the hot particles that had so much energy or kinetic energy suddenly reduces its energy and converts to water due to the change in temperature and pressure .
Thus condensation is the reason for clinging of water particles to the side of the glass having ice water.

1. How much heat is required to heat 22 grams of Aluminum from 15 °C to 49° C
Answer:
670.956
Explanation:
You can use this equation to solve for heat :
Q = m * c * ΔT
Q represents the heat
m represents the mass in kilograms
c is the specific heat. For aluminum, it's 897
ΔT is the change in temperature, so, 49 - 15 which is 34
Plug in the numbers and you get this :
Q = 0.022 * 897 * 34
Q = 670.956 Joules
