In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Answer:
365.212
Explanation:
According to the given situation, the calculation of molar mass is shown below:-
Data provided
Molar mass = 16 × 12 + 19 × 1.008 + 3 × 14 + 5 × 16 + 32.06
= 192 + 19.152 + 42 + 80 + 32.06
Molar mass = 365.212
Therefore for determining the molar mass we simply solve the above equation.
So, the correct answer is 365.212
Answer:
Cation
Explanation:
Since the protons are greater than electrons, this means the atom has a net positive charge on it and is now called a cation.
As there are 4 protons, this means that the outermost shell has 2 valence electrons 2s1, 2s2 and this is Group 2 element. Looking at Periodic table, we find that this is beryllium 4Be5 and is denoted as Be^2+
Answer:
High partial pressure of oxygen in the tissues.
Explanation:
Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.
When there is lack of oxygen in our bodies, we experience hypoxia.
