The atom that has a charge of -1 is atom 3.
To get the net ionic charge, we will use the formula as shown:
- Net ionic charge = Number of protons present in an ion + Number of electrons present in an ion.
For atom 1;
Net ionic charge = 9 - 9
Net ionic charge = 0
For atom 2;
Net ionic charge = 9 - 8
Net ionic charge = + 1
For atom 3;
Net ionic charge = 9 - 10
Net ionic charge = -1
For atom 4;
Net ionic charge = 9 - 9
Net ionic charge = 0
From the calculation above, the atom that has a charge of -1 is atom 3.
Complete question:
<em>Given the table;</em>
Atom (1) (2) (3) (4)
Number of protons 9 9 9 9
Number of neutrons 8 9 9 10
Number of electrons 9 8 10 9
Based on the table, which atom has a charge of -1

The best answer that describes the relationship between the rate of change with respect to time of the pressure and the rate of change with respect to time t of the volume is; dP/dt = (-k/V²)(dV/dt)
We are given;
p = k/v
Thus if we cross multiply, we will get;
PV = k
Where;
P is pressure
V is volume
k is a constant
- Using the product rule of differentiation on both sides with respect to time t gives;
V(dP/dt) + P(dV/dt) = 0
This is because k is a constant.
Putting k/v for P gives;
V(dP/dt) + (k/V)(dV/dt) = 0
>> V(dP/dt) = - (k/V)(dV/dt)
Divide both sides by V by division property of equality to get;
dP/dt = (-k/V²)(dV/dt)

Answer:
Answer: D . Their rulers claimed power by virtue of protecting Dar al-Islam from European invasion
Explanation:
There is no map attached however, based on a related question, I have reason to believe that the dynasties being described are the Mughal and Ottoman empires.
These empires were both chiefly Muslims and they claimed rulership over vast areas of land and insisted that they were doing so to spread the words of the Prophet Muhammad and to protect the lands of Islam from takeover by the Europeans and other religions.
Here, we are required to identify which of the amendments protects Chris who's on trial and does not want to testify in court.
- <em>The amendment which protects Chris from testifying is the Fifth amendment.</em>
The <em>Fifth Amendment </em>otherwise known as <em>Amendment V </em>to the Constitution of the United States primarily addresses criminal procedure while also addressing other aspects of the Constitution. It's ratification, along with some other articles, occured in 1791 as part of the <em>Bill of Rights.</em> <em>The Fifth Amendment is applicable to every level of the government, including the federal, state, and local levels, regarding a United States citizen or resident person in the United States.</em>
<em>The self-incrimination clause is characterized by its provision for various protections against self-incrimination, most importantly, the right of an individual to not serve as a witness in a criminal case in which they are the defendant.</em>
<em>The self-incrimination clause is characterized by its provision for various protections against self-incrimination, most importantly, the right of an individual to not serve as a witness in a criminal case in which they are the defendant.One colloquial term used to invoke the self-incrimination clause when witnesses decline to answer questions with answers that might </em>incriminate<em> them is "Pleading the fifth".</em>
Other provisions of the Fifth Amendment:
- Requires <em>indictment by a grand jury</em> as the only condition for which felonies be tried
- provides defendants with the right to be tried only once in federal court for the same offense --Double Jeopardy Clause
- provision which allows the federal government to take or perhaps seize private property for public use only if the government provides "just compensation." --Takings Clause
<em>Ultimately, the amendment which protects Chris from testifying is the Fifth amendment.</em>
