Equations represents the law of conservation of mass is 2H₂O → 2H₂ + O₂

Law of conservation of mass stated that energy neither be created nor destroyed called as law of conservation of mass and as the same no of each atom present in the both side of the reaction this reaction represents the law of conservation of mass so in the equation 2H₂O → 2H₂ + O₂ the energy cannot be created nor destroyed water can form 2 mole of hydrogen and 1 mole of oxygen which form water

. 20 mL ethanol in 60 mL solution
goldenfox [79]

The solution is the mixture of the solute into the solvent particles. In 60 mL solution, 59.8 mL of solvent is added.

<h3>What are solute and solvent?</h3>

Solute and solvent are the components of a solution. They react and mix together to produce a homogenous mixture. The solute is a substance that is added to the solvent.

Solvents are substances that dissolve the added solute in them to make a homogenous solution.

Given,

Volume of Solute = 0.20 mL

Volume of Solution = 60 mL

The volume of solvent is calculated as:

Volume of solvent = Volume of solution - Volume of solute

= 60- 0.20

= 59.8 mL.

Therefore, 59.8 mL of solvent is present in 60 mL of solution.

How does heat flow? Use the following keywords: heat, thermal energy, transfer, same, hot to cold, kinetic energy
Nitella [24]

Explanation:

is the movement of heat. ... Heat flows in solids by conduction, which occurs when two objects in contact with each other transfer heat between them. That happens because the molecules hit each other, and the faster moving molecules in the hot object spread that energy into the cooler object.

Plutonium-240 decays according to the function \[Q(t)=Q _{o}e ^{-kt}\] where Q represents the quantity remaining after t years a
marishachu [46]
To answer the question above, substitute the given values to the given equation,
                                   Q(t) = Q x e^-kt
  
                          12 grams = (36 grams) x e^(-0.00011)(t)

Solving for t gives t = 9,987.38 years or approximately equal to 9,990 years. Thus, the answer is letter C.

Regional climate is caused by factors around the planet because around the world, if the sun is facing the part of the world you are in, it's going to be hot. Or, in Alaska for example, it is almost always cold because it's most of the time facing away from the sun.
