Protons are one of the fully stable parts of matter
Answer: a 900 milliliter (ml) pitcher of orange juice at 20 degrees Celsius ( oC)
Explanation:
Thermal energy is the energy possessed by an object by virtue of its temperature. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.
Thermal energy refers to the sum of kinetic, potential, vibrational ,electronic and rotational energies of the object.
For bodies at same temperature, the body with more molecules will have more thermal energy due to more collisions.
Answer:
The final concentration is 0,151 M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We convert the unit of volume in L into ml: 3,25 x 1000= 3250 ml
We use the formula for dilutions:
C1 x V1 = C2 x V2
C2= (C1 xV1)/V2
C2= (32, 5 ml x 15, 1 M)/ 3250 ml
<em>C2=0,151 M</em>
I’m pretty sure it’s NH4, ammonium
Answer : The empirical formula is 
.
Explanation :
Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.
Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.
The given molecular formula is .
For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.
In the given formula, the valence is 1.
So, the empirical formula is .
