Answer:i’m not sure sorry
Explanation:
Answer:
trees collect energy from sitting in the sun, the interact with their enviorment because they provide oxygen, and they reproduce when their fruit flowers or leaves fall off.
Explanation:
Answer: density =3.377g/cm³
Explanation:
Density =( molecular weight × effective number of atoms per unit cell) / (volume of unit cell × avogadro constant)
D= (M ×n) /(V×A)
M= 137g/mol
n= 2 (For BCC)
V=a³ , where a= 4r/√3
a= (4×222)/√3
a=512.69pm
a= 512.69×10^-10cm
V= ( 512.69×10^-10)^3
V= 1.3476×10^-22cm³
D= (137×2)/(1.3476×10^-22 × 6.02^23)
D= 3.377g/cm³
Therefore the density of barium is 3.377g/cm³
Primitive cells, for example, yeasts and microscopic organisms utilize all sugars a similar way, gave that they can transport the starch into the cell. Huge atoms that can't be transported are separated remotely by compounds that the cells discharge.
All dietary starch must be processed into little atoms previously assimilation. Those little particles are chiral, pivoting spellbound light to one side or left.
Fluorine has C seven valence electrons.
Valence electrons are the electrons that are found on the outer shell of an atom that are capable of participating in chemical reactions. The easiest way to figure out how many valance electrons Fluorine has would be to look it up in a periodic table and notice that it a group 7 element and therefore has 7 valence electrons.
The other way to tell that Fluorine has 7 valence electrons is to notice that an element with an atomic number of 9 has 9 electrons. The electronic configuration of elements has the first 2 electrons go on the first shell or energy level 
, the leaving the next 7 to go to the second shell 
which can take up to 8 electrons.
This means that Fluorine has 7 seven valence electrons.
