Look up chromium on periodic table.
It's atomic number is 24.
It gives number of protons in an element.
Since the atom is uncharged (no extra or subtracted electrons), the number of protons will equal the number of electrons.
Answer:
False
Explanation:
Phosphorus is number 15 on the periodic table, so its electronic configuration is:
The volume of hydrogen gas that evolved is calculated as follows
by use of ideal gas equation
that is PV = nRT
P=745 mm hg
V= ?
R(gas constant)= 62.36 L.mm hg/mol.k
T= 20 + 273 = 293 k
n=number of moles which is calculated as follows
find the moles of Na used
= 0.52/23=0.023 moles
write the reacting equation
2Na +2H2O =2NaOH +H2
by use of reacting ratio between Na : H2 which is 2:1 therefore the mole of H2 = 0.023/2 =0.0115 moles
by making the volume the subject of the formula
v=nRT/P
V= (0.0115 x 62.36 x 293) / 745 = 0.283 L
If you have a hamster with short fur, what possible genotypes could the hamster have?
Answer: <u>FF or Ff </u>
Explanation:
If you have a hamster with short fur, what possible genotypes could the hamster have? FF or Ff . ... The mystery hamster was a genotype ff and the phenotype for long fur and the parents can create offspring that have long fur or short fur because they are heterozygous dominant.
