Fishes yes according to the age, reptiles yes
Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g
Unknown:
Amount of energy = ?
Solution:
This is a phase change process from solid to liquid. In this case, the latent heat of melting of ice is 3.33 x 10⁵ J/kg.
So;
H = mL
m is the mass
L is the latent heat of melting ice
Now, insert the parameters and solve;
H = mL
mass from gram to kilogram;
100g gives 0.1kg
H = 0.1 x 3.33 x 10⁵ = 33300J
Answer:
there are three fundamental particles of atom
which are :
- proton ( positively charged (+) )
- electron ( negatively charged ( - ) )
- neutron ( having no charge on it ( neutral ))
Particle Symbol
electron =》e-
proton =》p+
neutron =》n°
The sample with the largest number of oxygen atoms will be calcium perchlorate.
<h3>Number of atoms in a compound</h3>
Since we are not looking at the number of moles, the mass of the compounds has no bearing on the number of atoms of oxygen.
- The chemical formula for carbon dioxide is
. Thus, it has 2 atoms of oxygen. - The chemical formula for potassium chlorate is
. Thus, it has 3 oxygen atoms. - The chemical formula for calcium perchlorate is
. Thus, it has 8 atoms of oxygen. - The chemical formula for sodium hydroxide is NaOH. Thus, it has 1 atom of oxygen.
Therefore, the compound with the largest number of oxygen atoms is calcium perchlorate.
