Answer 2, because when you add salt to something, it cools faster (ex. When you add salt to an ice chest so that it stays cold) and it takes longer to boil (ex. When you boil salt out of ocean water so that its safe to drink) therefore, the more NaCl in the solution, the more it will exibit these properties
Chemical change occur when two substances are combined and produces a new substance or decomposes into two or more substances which are entirely different from the original two substances.
There are three types of chemical changes. These are 1) Inorganic Changes, 2) Organic Changes, and 3) Biochemical Changes
Here are some examples of chemicsal changes.
If you combine Sodium and Water, chemical changes causes decomposition into Sodium Hydroxide and Hydrogen.
Sodium + Water ==> Sodium Hydroxide and Hydrogen
Na + H2O ====> NaOH and H
Another example of chemical change is:
Carbon Dioxide and Water will decompose into Sugar and Oxygen
Carbon Dioxide + Water ==> Sugar and Oxygen
CO2 + H2O ==> CnH2nOn (where n is between 3 and 7) and O
Number 3 i think is <span>d.heat moves from an object of higher temperature to an object of lower temperature</span>
Answer:
12.
1 + 2 + 1 = 4 + 1 + 2 + 1 + 4 = 12 = 4 + 1 + 2 + 1 + 4 = 1 + 2 + 1
Answer:
please mark as brainliest!!
Explanation:
// C++ program to print initials of a name
#include <bits/stdc++.h>
using namespace std;
void printInitials(const string& name)
{
if (name.length() == 0)
return;
// Since touuper() returns int, we do typecasting
cout << (char)toupper(name[0]);
// Traverse rest of the string and print the
// characters after spaces.
for (int i = 1; i < name.length() - 1; i++)
if (name[i] == ' ')
cout << " " << (char)toupper(name[i + 1]);
}
// Driver code
int main()
{
string name = "prabhat kumar singh";
printInitials(name);
return 0;
}
