Answer: A woman kicks a soccer ball and scores a goal.
Explanation:
Potential energy: it is the energy possessed by the body due to its position.
Kinetic energy: it is the energy possessed by the the body due to its motion.
When a woman kick's a soccer ball she transferred her potential energy to soccer ball.Due to this action soccer ball comes into motion which means potential energy imparted to the ball starts getting converted into kinetic energy.
Answer:
A. 11
Explanation:
atoms are made of three types of sub atomic particles - protons, neutrons and electrons
Protons are positively charged, electrons are negatively charged and neutrons are neutral.
Protons and neutrons are located inside the nucleus and electrons orbit around the nucleus in energy shells.
Atoms make up an element and atoms are neutral charged with an equal number of protons and electrons. Neutral atom of sodium would therefore have an equal number of positive charges and negative charges.
Since Na has 11 protons, for it to be neutral it would have 11 electrons
Answer:
The answer to your question is 1 mol of Fe₂O₃
Explanation:
Data
mass of Fe = 112 g
mass of Fe₂O₃ = ?
Balanced chemical reaction
Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂
Process
1.- Calculate the molar mass of Fe₂O₃ and 2Fe
molar mass Fe₂O₃ = (56 x 2) + (16 x 3) = 160 g
molar mass of Fe = 56 x 2 = 112 g
2.- Use proportions to calculate the mass of Fe₂O₃ formed
160 g of Fe₂O₃ ----------------- 112 g of Fe
x ----------------- 112 g of Fe
x = (112 x 160)/112
x = 160 g of Fe₂O₃
3.- Calculate the moles of Fe₂O₃
160 g of Fe₂O₃ ------------------ 1 mol
160 g of Fe₂O₃ ------------------ x
x = (160 x 1)/160
x = 1 mol of Fe₂O₃
I believe the correct answer from the choices listed above is the first option. The compound that contains both ionic and covalent bonding is KOH or potassium hydroxide. It contains one covalent<span> (O-H) and one that is </span>ionic<span> (K-O). Hope this helps.</span>
The Impact of stirring and increasing the temperature during solution formation is that they both increase the rate at which the solute particles dissolve in the solvent.
<h3>What is Dissolution?</h3>
Dissolution is the process in which a solute dissolves to form a solution.
The solute can either be gas, liquid, or solid.
Stirring increase rate of particle collision and therefore increase dissolution.
Therefore, impact of stirring and increasing the temperature during solution formation both increase the rate at which the solute particles dissolve in the solvent.
