What an electron and a neutron have in common is that <u>each particle exists inside an atom,</u>
Atoms consist of three particles: protons (which are positively charged), electrons (which are negatively charged), and neutrons (which have no charge).
Answer:- 23.8 kJ of heat is required to raise the temperature of water.
Solution:- We have been given with grams of water, it's initial and final temperature and asked to calculate the heat required to raise it's temperature. Here, lower degree C water is changing into higher degree C water. So, the formula used to calculate the heat is:
Where, q is the heat energy, m is mass, c is specific heat of water and delta T is change in temperature.
m = 100 grams
= 82 - 25 = 57 degree C
q=?
Let's plug in the values in the formula and do the calculations:
q = 23848.8 J or 23.8 kJ
So, 23.8 kJ of heat is required to raise the temperature of 100 g of water from 25 to 82 degree C.
0.69moles
Explanation:
Given parameters:
Number of atoms = 4.14 x 10²³atoms
Atom = Na
Unknown:
Number of moles of Na atom in it = ?
Solution:
A mole of a substance is the quantity of substance that contains the avogadro's number of particles.
1 mole = 6.02 x 10²³particles
To solve this problem, simply use the expression below;
Number of moles =
Input the parameters;
Number of moles = = 0.69moles
