Answer:
fist one is freezing next two is condensation
Explanation:
Answer:
Approximately 
, assuming that all sulfur in that coal was converted to 
.
Explanation:
Look up the relative atomic mass of 
and 
on a modern periodic table:
Convert the unit of the mass of coal to grams:
.
Mass of sulfur in that much coal:
.
The relative atomic mass of sulfur is 
. Therefore, the mass of each mole of sulfur atoms would be 
. Calculate the number of moles of atoms in that 
of sulfur:
.
Each 
molecule contains one sulfur atom. Therefore, assuming that all those (approximately) 
of sulfur atoms were converted to molecules through the reaction with 
, (approximately) 
of 
molecules would be produced.
Calculate the mass of one mole of molecules:
.
The mass of that of molecules would be:
.
Answer:
Explanation:
In a simple cubic lattice lattice, the atoms are present at the eight corners of the cibe.
Since it is mentioned that the fluorine is present at the corners and also 1 corners are shared by 8 unit cells. So, share of atom in one unit cell is:- 
Also, the metal, M occupy half of the body centre. A cube has only one body centre. So, share of M in each unit cell:- 
Thus, the formula is:-
Or simplifying
Answer:
The temperature change is 80°C
Explanation:
Heat absorbed by the melting ice (Q) = mL = 312×336 = 104,832 J
∆T = Q/mC = 104,832/312×4.2 = 80°C
Answer:
1) represented by a lower case letter
2) always masked by dominant genes
3) only expressed in the absence of a dominant gene
Explanation:
So if I take a black and a yellow marker- and tried drawing the yellow over the black- or the other way around- you'd still only see the black marker. The recessive trait is like the yellow marker. Now if I drew the yellow marker with another yellow marker you would see the yellow. I hope this helps!
