Answer:

Stopwatches versus clocks. To improve reliability repeat the experiment multiple times according to an identical procedure. Record these steps so the experiment can be repeated at any time

In the diagram, what is happening to the ENERGY during Segment C? Phase Change Diagram_Water Question 16 options: The kinetic en
Leviafan [203]

There was an increase in kinetic energy during the segment C and in other segments

Recall: That temperature is a measure of the average kinetic energy, so increasing temperature all cause increasing kinetic energy and vice versa.

However too, the heat energy which is added during the phase change is usually used to overcome forces in order to hold the molecules together.

<h3>What is kinetic energy?</h3>

Kinetic energy is the type of energy an object or a body posesss due to it motion

The body usually maintains it's kinetic energy unless the speed changes

<h3>What it potential energy?</h3>

Potential energy is a type of energy an object or a body had due to its relative position.

Are nuclear bombs ethical? Explain please
Mrac [35]

Answer:

<u>Yes, they are.</u>

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.

Explain your thoughts on whether or not using solely IR is a good method to make positive IDs of chemicals.
Fed [463]

Answer:

No, IR should not soely be used to identify molecules

Explanation:

IR is a method that identifies the functional groups in a molecule by deducing the frequency of stretching and vibration of bonds. Each peculiar type of bond has a frequency for the vibration of each bond represented on the IR spectrum.

However, one method is never enough to identify a compound. A combination of methods must always be used to clear up ambiguities arising from overlapping IR frequencies. Also,  interpretation of the nuanced peaks of the fingerprint region in IR spectra is quite challenging and only gives a fair idea of the functional groups present in the compound.

Therefore other methods such as NMR, UV-VISIBLE etc should also be involved in the identification of compounds.

Define the term ligand. Cu2+(aq) reacts with ammonia to form the complex ion
photoshop1234 [79]
The answer is ligand: a molecule or ion that can bond to a (central) metal ion (to form a complex);
NH3: Lewis base and Cu2+: Lewis acid (need both for mark);
<span>each NH3/ligand donates an electron pair (to Cu2+); forming coordinate covalent/dative covalent bond; i hope this help you.</span>
