The answer to this is a carbohydrate compound. Carbohydrates have a general chemical formula of Cₓ(H₂O)ₓ. From the word itself, there is a ratio for every carbon atom that corresponds with the hydrate molecule or water. So, an empirical formula for a carbohydrate is CH₂O which coincides with the 1:2:1 ratio.

Rank the following atoms by number of valence electrons. Rank from most to fewest valence electrons. To rank items as equivalent
Fed [463]

To count the number of valence electrons we look at the electronic configuration and add the electrons form the electronic shell with the highest principal quantum number.

Rb: [Kr] 5s¹ - 1 valence electron

Xe: [Kr] 5s² 4d¹⁰ 5p⁶ - 8 valence electrons

Sb: [Kr] 5s² 4d¹⁰ 5p³ - 5 valence electrons

I:    [Kr] 5s² 4d¹⁰ 5p⁵ - 7 valence electrons

In:  [Kr] 5s² 4d¹⁰ 5p¹ - 3 valence electrons

Rank from most to fewest valence electrons:

Xe > I > Sb > In > Rb

How much heat energy is required to raise the temperature of 0.360 kg of copper from 23.0 ∘C to 60.0 ∘C? The specific heat of co
AVprozaik [17]
MThe  heat  energy  required  to  raise  the  temperature   of  0.36Kg   of  copper   from   22 c   to  60  c  is  calculate  using  the  following  formula

MC delta T
m(mass)=  0.360kg  in  grams  =  0.360  x1000 = 360 g
  c(specific  heat  energy)  =  0.0920  cal/g.c
delta T =  60- 23  = 37  c

heat  energy is therefore=  360g   x0.0920 cal/g.c  x 37  c=  1225.44  cal

Meiosis occurs in<br> embryo cells<br> plant cells<br> reproductive cells<br> animal cell
Law Incorporation [45]

Answer:

Meiosis is a type of cell division - like mitosis, but it results in four haploid cells with one-half the number of chromosomes as the original diploid cell. Meiosis occurs in plants only during sexual reproduction in specialized cells to produce a haploid egg cell.
