Answer:
He traveled at a speed of 4 m/s with a velocity of 4m/s north, and his acceleration changed when stopping for lunch.
Explanation:
Trust me took test got it right!
<span>There are a number of ways
to express concentration of a solution. This includes molarity. Molarity is
expressed as the number of moles of solute per volume of the solution. We can calculate as follows:
Mass of KOH = 1.50 mol KOH/ L solution (2.50 L) (56.11 g/mol) = 210.41 g KOH
Therefore, the first option is the answer. </span><span />
Answer:
Whether you get the metal or hydrogen during electrolysis depends on the position of the metal in the reactivity series: the metal will be produced if it is less reactive than hydrogen. hydrogen will be produced if the metal is more reactive than hydrogen.
A solution
Explanation: A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size.
Each substance has its own unique structure and properties that are based on these structures.
One of those most important properties is the "specific heat" value.
Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius.
Each substance has its own specific heat. The higher the specific heat of a substance, the longer it will take to heat up or cool down.
Hope this helps :)
