Answer:
It maintains a constant internal temperature.
Explanation:
Our body tries its hardest to maintain a constant internal temperature. This is because if we get to warm or cold it is unhealthy. If your body senses that it is getting to warm or cold it will try to correct itself.
Answer:
Explanation:
The biocapacity or biological capacity of an ecosystem is an estimate of its production of certain biological materials such as natural resources, and its absorption and filtering of other materials such as carbon dioxide from the atmosphere.
Answer:
C) P3– > Cl– > K+ > Ca2+
Explanation:
Ionic radius can be defined as the distance between the nucleus and the electron in the outermost shell of atom in its ionic state. When an atom looses an electrons(Cation) its ionic radius decreases, whereas when an atom gains an electron(anion), its ionic radius increases.
Among the given ions the ionic radius of
all distances are in picometer.
clearly,
option C is correct that is
C) P3– > Cl– > K+ > Ca2+
A-14
Explanation:
Mass number (MN) = Proton number + Neutron number
MN=7+7
MN=14
M(Li₃PO₄)=115.8 g/mol
c(Li⁺)=0.175 mol/L
v=500 mL= 0/5 L
n(Li⁺)=3n(Li₃PO₄)=3m(Li₃PO₄)/M(Li₃PO₄)=c(Li⁺)v
m(Li₃PO₄)=c(Li⁺)vM(Li₃PO₄)/3
m(Li₃PO₄)=0.175*0.5*115.8/3=3.3775* g
*Solubility lithium phosphate in water about 0,34 g/L. Litium phosphate can be dissolved in solution of a phosphoric acid. For example:
2Li₃PO₄(s) + H₃PO₄(aq) = 3Li₂HPO₄(aq)
