Analyze how humans use technology to store (potential) and/or use (kinetic) energy.*
Science btw
Answers
Human devices use potential energy to store energy, whereas kinetic energy is potential energy in motion. Both types of energies can be measured in Joules (J).
Human devices generate and use different sources of energy, which can be classified into renewable sources (e.g., solar, hydraulic, winds, etc) and non-renewable sources (e.g., nuclear energy) of energy.
For example, a hydroelectric power plant transforms the potential energy stored in water reservoirs (e.g., a lake) into mechanical energy (a type of kinetic energy) when this energy is released from the water reservoir and flows through a turbine.
Subsequently, this type of kinetic energy is then used to generate electricity.
On the other hand, a nuclear power plant uses the potential energy that is stored within the nuclei of atoms to produce kinetic energy by a process known as nuclear fission.
This process (nuclear fission) releases energy in the form of heat (i.e., thermal energy).
Subsequently, this type of kinetic energy (heat) is used to generate steam, which then moves turbines to generate mechanical energy and finally generates electricity.

d. N2
Answers
Solubility refers to the ability of substances to dissolve in a solvent. Of the gases listed here, that which would most likely dissolve in water is;
a. CO2Carbon dioxide is a gas that has a very high solubility in water. When bubbled through water, 99% of the gas dissolves while 1% of the gas comes off as carbonic acid.
The solubility of carbon dioxide increases with an increase in pressure and decreases with an increase in temperature.
Therefore, option A is correct.

B. The offspring get DNA from two parents, and it combines randomly.
C. The offspring get DNA from one parent, and it mutates regularly.
D. The offspring get DNA from one parent, and it combines randomly.
Answers
Organisms that reproduce sexually have offspring with greater variety because: B. The offspring get DNA from two parents, and it combines randomly.
Reproduction refers to a biological process through which living organisms (parents) mate to produce offspring.
Basically, there are two (2) main types of reproduction and these include;
Asexual reproduction.Sexual reproduction.During sexual reproduction, parent organisms produce offspring with greater variety because the genetic material of their parents are randomly combined to produce genetically-diverse offspring.

Answers
Answer:
it boils a liquid to create condomsation
Explanation:
Answer:
Distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture. It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture. The process of distillation exploits the difference in the boiling points of the components in the liquid mixture by forcing one of them into a gaseous state.

draw the major and minor product when the following alkyl halide is heated with sodium ethoxide in ethanol. you may neglect cis-trans isomerism of the products when answering this question. if there is only one product, click no reaction for the minor product.
Answers
The major product is 3-methyl-2-pentene and the minor product is 2-ethyl-1-butene.
The alkyl halide shown is 3-bromo-3-methyl pentane. We can see that it is a tertiary alkyl halide. The proportion of products formed during the reaction are determined by Markovnikov rule.
The two products of this reaction are; 3-methyl-2-pentene and 2-ethyl-1-butene. The major product is 3-methyl-2-pentene because it is formed from a more stable carbocation intermediate. 2-ethyl-1-butene is the minor product.

If you dissolve 0.1 mol of formic acid in 1 L of water, ther esulting solution contains 0.004 mol of H₃O+. Based on this information, is formic acid a strong acid, or is it a weak acid?
Answers
Answer: Consider the equilibrium of the generalized acid, HX , in aqueous solution….
HX(aq)+H2O(l)⇌H3O++X−
As we FACE the page, the given reaction, with FORMIC acid, HC(=O)OH , produces ONLY millimolar concentration with respect to hydronium ion, and acetate ion … and thus, as anticipated, formic acid is a WEAK acid…. pKa=3.79 .
i.e. Ka=(0.004∙mol∙L−1)20.10∙mol∙L−1−0.004∙mol∙L−1=1.60×10−4
pKa=−log10(1.60×10−4)=−(−3.79)=+3.79
….formic acid is nevertheless a STRONGER acid than acetic acid, for which pKa=+4.76 .
