1-How many moles of NazCOs are in 10.0 ml of a 2.0 M solution?
Answers
Answer:
A solution is a mixture in which the particles are so small that the components are indistinguishable from each other. The amount of the solute and the solvent in a solution can be expressed in terms of different concentration expressions such as molarity, morality, etc.
Explanation:
To calculate the number of moles of sodium carbonate, the volume in liters will be multiplied by the molar concentration of the solution.
moles Na2CO3 = 2.0 M x 0.0100 L = 0.020 moles Na2CO3
Hope it helps :)
Answer:
There are 20. mol of Na2CO3 in 10.0L of 2.0M solution.
Explanation:
Molarity is represented by this equation:
(look at attachment)
In our case, we already have the molarity and volume of solution, both of which have good units.
Let's rearrange the equation to solve for the number of moles. We can do this by multiplying by L solution on both sides of the equation. The L solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume:
Moles of solute
=Lsolution×Molarity
Now we just plug the known values in!
Moles of solute = (10.0 L) (2.0M) = 20. moles

Which term refers to a cloud-native, streamlined technology for hosting cloud-based applications, where a server runs for short bursts only when needed by an application or service
Answers
Answer:
Serverless computing.
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
The three (3) main characteristics of cloud computing are;
I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.
II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.
III. Elasticity: this is the ability of the cloud computing service to be flexible and adaptive to the traffic or requests from the end users.
Serverless computing is a term which refers to a cloud-native and streamlined technology that is designed typically for hosting cloud-based applications, in which a server operates for short bursts only when needed by an application or service. Serverless computing is used for the allocation of machine resources on demand.

It exists positively suggested that drives in a RAID array be of the exact type and size. With RAID 0 or RAID 1, you'd require at least two drives, so you would require to buy one additional drive in most cases. With RAID 5 you'll require at least three drives, so two additional drives, and with RAID 6 or 10 you'd require at least four total drives.

Write function d2x() that takes as input a nonnegative integer n (in the standard decimal representation) and an integer x between 2 and 9 and returns a string of digits that represents the base-x representation of n.
Answers
Answer:
The function in Python is as follows:
def d2x(d, x):
if d > 1 and x>1 and x<=9:
output = ""
while (d > 0):
output+= str(d % x)
d = int(d / x)
output = output[::-1]
return output
else:
return "Number/Base is out of range"
Explanation:
This defines the function
def d2x(d, x):
This checks if base and range are within range i.e. d must be positive and x between 2 and 9 (inclusive)
if d >= 1 and x>1 and x<=9:
This initializes the output string
output = ""
This loop is repeated until d is 0
while (d > 0):
This gets the remainder of d/x and saves the result in output
output+= str(d % x)
This gets the quotient of d/x
d = int(d / x) ----- The loop ends here
This reverses the output string
output = output[::-1]
This returns the output string
return output
The else statement if d or x is out of range
else:
return "Number/Base is out of range"

Assume a file containing a series of names (as strings) is named names.txt and exists of computer's disk. Write a program that displays the number of names that are stored in the file. While open and read data - check it for the most common exceptions.
Answers
Answer:
The program in Python is as follows:
fname = open("names.txt","r")
num = 0
for line in fname:
try:
line = float(line)
except ValueError:
num+=1
fname.close
print(num,"names")
Explanation:
This opens the file for read operation
fname = open("names.txt","r")
This initializes the number of names to 0
num = 0
This iterates through the lines of the file
for line in fname:
This runs a value check exception on each name to check for valid strings

Arrays of structures ________. Group of answer choices None of the above. are automatically passed by reference cannot be passed by reference are automatically passed by value
Answers
Answer:
are automatically passed by reference.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
This ultimately implies that, parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.
This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.
A character positions in arrays start counting with the number 0 not 1.
Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
Generally, arrays of structures are automatically passed by reference through the use of a REPLICATE function.

Explanation:
Given - When adding several user accounts, you might want to use the new users utility, which can process a text file full of entries to add user accounts.
To find - Use the man or info page to find out how to use this utility, and use it to add three users.
Proof -
New Users Utility:
It is an utility which reads the file full of usernames and clear text passwords.
It then uses this information to update a group of the existing users to create new users.The format of the file consists of specified things like:
pw - passwd
pw - age
pw - gid
pw - dir
Use of the Utility:
The command is new users filename
The file should look like -
(Username : Password : UID : GID : User Information : Home Directory : Default Shell)
where ,
UID = User Identifier
GID = Group Identifier
Testing the Users:
Creating users from the file given above test User 1, directory Of File
Executing the create user new users directory Of File
Repeat this step to undergo all the users that are been noted down in the file to make them a user in the noted group policy.
Hence,
These are the steps of using the new Users utility.
You designed a program to create a username using the first three letters from the first name and the first four letters of the last name. Usernames cannot have spaces. You are testing your program with a user whose name is Jo Wen. What step in the program plan do you need to revisit

Answer:
See Explanation
Explanation:
The question would be best answered if there are options to select from; since none is provided, I will provide a general explanation.
From the question, we understand that, you are to test for Jo Wen.
Testing your program with this name will crash the program, because Jo has 2 letters (3 letters are required), and Wen has 3 letters (4 letters are required)
So, the step that needs to be revisited is when the username is generated.
Since the person's name cannot be changed and such person will not be prevented from registering on the platform, you need to create a dynamic process that handles names whose lengths are not up to the required length.

By replacing the workstations 100 Mbps switches with 1000 Mbps switches the problem of
Starvation; been faced by the servers due to the delay in sending data to be processed by the servers from the workstations will be resolved .
Flow control : The huge difference in the speeds of the workstations and servers causes a network buffer which leads to packet loss therefore when the workstations 100 Mbps switch is replaced with 1000 Mbps switch this network problem will be resolved
b) The potential problem that can be encountered is Network Congestion
