Answer:
the variable A represented specific heat capacity
1 mole of anything always contains 6.02x10^23 molecules or moles (this is Avogadro's number). you can use this ratio to find the number of atoms or molecules in any given amount of substance. Due to that 0.0012 moles can be multiplied by Avogadro's number to find that 0.0012 moles of anything contains 7.224x10^20 atoms or molecules depending on what type of substance you are looking at. Aluminum consists of atoms while octane consists of molecules.
I hope this helps. Let me know in the comments if anything is unclear.
Answer:
#include <iostream>
using namespace std;
int main() {
int n;
cin>>n;//taking input form the user.
bool b=true;
for(int i=2;i<n;i++)//looping
{
if(n%i==0)//checking that i divides n.
{
cout<<"The number is not prime";
b=0;
break;
}
}
if(b)
{
cout<<"The number is prime";
}
return 0;
}
Input:-
23
Output:-
The number is prime.
Explanation:
The above written program is in C++.First I have declared an integer n.Then taking input form the user and storing it in n abd also declared a boolean variable with value true.Then I have used a for loop for checking n is divisible by any number from 2 to n-1 if it is then printing the message of not prime,making the value of b to false and coming out of the loop.out of the loop if the value of the b is true then printing the number is prime.
Answer:
A. How Acidic the solution is
Explanation: pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
