<u>Answer;</u>
Matter is converted to energy
<u>Explanation;</u>
- Nuclear fission is a type of nuclear reaction in which a nuclei of an atom splits or breaks down into two or more smaller nuclei.
- It involves subdivision of heavy nucleus of an atom such as Uranium into two or more fragments which has almost the same equal mass.
- Nuclear fission is accompanied by release of large amount of energy, thus we can say that matter is converted to energy.
Answer:Sugars are actively transported from source cells into the sieve-tube companion cells, which are associated with the sieve-tube elements in the vascular bundles. ... The co transport of a proton with sucrose allows movement of sucrose against its concentration gradient into the companion cells.
Explanation:
Answer:
1.35g
Explanation:
times the density and volume together to get the mass
0.9 x 1.5 = 1.35g
Answer:
a. Polar
b. Polar
c. Non-polar
d. Non-polar
Explanation:
a. 
, hydronium cation contains a positive charge. Just as any other ion, it is polar, as it has a net charge.
b. 
has the same shape as water. There are two lone pairs on sulfur atom which produce an overall dipole moment in this molecule, the bent structure is polar.
c. 
is non-polar, as the central atom, phosphorus, doesn't contain any lone pairs, all the dipole moments cancel out: two dipole moments in the vertical plane, P-Cl, and three P-Cl dipoles in the horizontal plane within a trigonal bipyramidal shape.
d. 
is non-polar, since it's a tetrahedral molecule with no lone pairs on carbon atom, all four C-F dipole moments cancel out to yield a net 0 dipole moment.
The molecular formula of water and ammonia is 
and 
respectively.
From the atomic symbol of water it is clear that 1 mole of water contains 2 moles of hydrogen.
So, 
molecules of water contains 
atoms of hydrogen.
From the atomic symbol of ammonia it is clear that 1 mole of ammonia contains 3 moles of hydrogen.
So, 
molecules of ammonia contains 
atoms of hydrogen.
Total number of hydrogen atoms present in the solution = number of hydrogen atoms in water + number of hydrogen atoms in ammonia.
Substituting the values,
Total number of hydrogen atoms present in the solution = 
Total number of hydrogen atoms present in the solution = 
.
Hence, the total number of hydrogen atoms present in the solution is 
atoms.
