Explain why chemical equations have to be balanced.
Answer:
k
Explanation:
They must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.
Answer:
No matter is ever “lost” during a chemical reactions. This is called the law of conservation of mass. But sometimes the way equations are written to make it look liked atoms disappeared so we balanced them so the atoms on both sides of equal.

what is a water cycle? with explanation please I'm doing research.
Answer:
a cycle of water that circulates between earth's oecans
Explanation:
hope that's helps
Answer:
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Which 2 letters have the most kinetic energy?
The two (2) letters which have the most kinetic energy are: X and Z.
Kinetic energy is an energy that is possessed by a physical object or body due to its motion.
Mathematically, kinetic energy is calculated by using the formula;
[tex]K.E = \frac{1}{2} MV^2[/tex]
Where:
K.E is the kinetic energy.M is the mass of an object.V is the velocity of an object.Basically, the kinetic energy possessed by an object is highly dependent on its mass and velocity.
From the image attached, the car gains more velocity as it travels down the slope and as such has the most kinetic energy at point X and Z.
In conclusion, kinetic energy is greatest at the bottom of a slope while potential energy is least and vice-versa.
