Which has more energy, 5 kilograms of dynamite or 10 kilograms of dynamite? Why?
Answers
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:

Answer:
10 kilograms of dynamite

The more volume an object has the more potential energy is available if it is the same material. 10 kilograms is larger than 5 kilograms.

C. It breaks rocks into sediment.
D.It decreases pressure on buried rocks.

Sometimes forces act to pull sections of the Earth's crust apart. At other times they are forced together. All this movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift.

If 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L, the concentration of the resulting solution is A0.025 M B 0.050 M C 0.10 M D 0.50 M E 1.0 M M
Answers
Answer: The concentration of the resulting solution is 0.025 M
Explanation:
According to the dilution law,
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = molarity of concentrated [tex]NaOH[/tex] solution = 1.0 M
[tex]V_1[/tex] = volume of concentrated [tex]NaOH[/tex] solution = 50 ml
[tex]M_2[/tex] = molarity of diluted [tex]NaOH[/tex] solution = ?
[tex]V_2[/tex] = volume of diluted [tex]NaOH[/tex] solution = 2.0 L = 2000 ml (1L=1000ml)
Putting in the values we get:
[tex]1.0\times 50=M_2\times 2000[/tex]
[tex]M_2=0.025M[/tex]
Therefore, concentration of the resulting solution is 0.025 M
The concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M
HOW TO CALCULATE FINAL CONCENTRATION:
The concentration of a solution can be calculated by using the following formula:C1V1 = C2V2
Where;
C1 = initial concentration (M)C2 = final concentration (M)V1 = initial volume (L)V2 = final volume (L)According to this question;
C1 = 1.0MV1 = 50mLC2 = ?V2 = 2000mL = 2L1 × 50 = C2 × 200050 = 2000C2C2 = 50 ÷ 2000C2 = 0.025MTherefore, the concentration of the resulting solution if 50. mL of 1.0 M NaOH is diluted with distilled water to a volume of 2.0 L is 0.025M.Learn more at: https://brainly.com/question/17329736?referrer=searchResults

Based on table N of the reference tables what is the number of hours required for 42k (potassium -42) to undergo three half-life periods
Answers
The number of hours required : 37.2 hours
Further explanationGiven
⁴²K (potassium -42)
Required
The number of hours
Solution
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually, radioactive elements have an unstable atomic nucleus.
Based on Table N(attached), the half-life for ⁴²K is 12.4 hours, which means half of a sample of ⁴²K will decay in 12.4 hours
For three half-life periods :

Both ice and glass comes under the category of solids since they have definite shape and definite volume. Both the ice and glass allows light to pass through it, that means they are transparent in nature.Ice floats, we can infer that ice must be less dense than water. If water is frozen in a glass jar, the glass jar breaks. This implies they both have similar densities.Thus, options B and C are correct.

Water is produced from the reaction of hydrogen and oxygen gas, according to the equation below. What is the excess reactant in the reaction of 4.2 moles of hydrogen with 3.0 moles of oxygen?
2H2(g) + O2(g) = 2H2O(L)
Select one:
a. Water
b. Oxygen
c. No excess reactant
d. Hydrogen
Answers
Explanation:
Mole ratio of Oxygen to Hydrogen gas = 1 : 2.
If we use 3.0 moles of oxygen gas, we would need 3.0 * 2 = 6.0 mol of hydrogen gas.
However we only have 4.2 mol of hydrogen. Therefore hydrogen is limiting and oxygen is in excess. (B)
