What is the formula for pH?
Answer:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
Example: Find the pH of a 0.0025 M HCl solution.

Q3. When copper (II) chloride reacts with silvernitrate, copper (II) nitrate and silverchloride are formed.Write the balanced equation for the reaction given above:A.CuCl2(aq) + 2 AgNO3(aq) →Cu (NO3)2(aq) + 2 AgCl(s)B.CuCl2(aq) + NaNO3(aq) →Cu (NO3)2(aq) + AgCl(s)C.CuCl2(aq) + 2 NaNO2(aq) →Cu (NO2)2(aq) + 2 AgCl(s)D.CuCl(aq) + NaNO3(aq) →Cu NO3(aq) + AgCl(aq
Answer:
See explanation
Explanation:
When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.
After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;
CuCl2 + 2AgNO3 -------> Cu(NO3)2 + 2AgCl
Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill
Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E = [tex]\frac{1}{2}mv^2[/tex]
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.
How do the mass number and atomic change as a particle goes through beta decay
Answer:
The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus
Hope this helped!

What holds solid parties together?
Answer:
The cool people like me XD
Explanation:
Answer:
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.
