Answer:
A positively charged nucleus consisting of protons and neutrons
Explanation:
The atomic nucleus is a positively charged region located at the core of an atom that consists of positively charged protons and neutral neutrons while the negatively charged electrons make up the outer cloud (electrons are therefore not contained in the nucleus).
2, because they are all a form of water.. but just in different states of matter depending on their form
Answer:
Gravitational potential energy transforms into thermal energy.
Explanation:
Answer:
0.735M
Explanation:
The balanced equation of reaction is:
HCl + KOH ===> KCl + H2O
Using titration equation of formula
CAVA/CBVB = NA/NB
Where NA is the number of mole of acid = 1 (from the balanced equation of reaction)
NB is the number of mole of base = 1 (from the balanced equation of reaction)
CA is the concentration of acid = 2.5M
CB is the concentration of base = to be calculated
VA is the volume of acid = 14.7mL
VB is the volume of base = 50mL
Substituting
2.5×14.7/CB×50 = 1/1
Therefore CB =2.5×50×1/14.7×1
CB= 0.735M
Answer:
The main role of DNA in the cell is the long-term storage of information.The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Hope this helps! (:
