Answer:

Biodiesel has a higher oxygen content (usually 10 to 12 percent) than petroleum diesel. ... Biodiesel is more chemically active as a solvent than petroleum diesel. As a result, it can be more aggressive to some materials that are normally considered safe for diesel fuel. Biodiesel is much less toxic than petroleum diesel.

How much energy is required to heat 40g of water from -7 degrees Celsius to 108 degrees Celsius (Lf= 335,000J/Kg for ice)
solniwko [45]
The   energy  required  to heat  40g  of water  from -7 c  to 108 c is
1541000  joules

     calculation

Q(heat)=  M( mass)  x c(specific heat capacity) xdelta t( change in temperature)

M=  40g=  40/1000= 0.04 Kg
C=  335,000 j/kg/c
delta T   (    108 --7= 115  c)

Q  is therefore   =  0.04 g x  335000 j/kg/c  x 115 c  = 1541,000  joules

Try moving an electron from the metal to the nonmetal. What happens?
skad [1K]

Answer:

Explanation:

When electron is transfer from metal to non metal anion and cations are formed and compound formed is called ionic compound.

Ionic bond:

It is the bond which is formed by the transfer of electron from metal to the atom of non metal.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity thus the atom which accept the electron is form anion and metal atom which lose the electron is form cation .

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion the compound form is called sodium chloride.
