Answer: Option E. There are covalent bonds between the hydrogen atoms
Explanation:
Answer: Last week, he accidentally dropped his coffee mug, which then fell on the floor due to gravity.
A scientific law can be defined as a law which followed universally. As a scientific law gives evidences and facts related to a natural phenomena. It is useful in scientific education and research.
Last week, he accidentally dropped his coffee mug, which then fell on the floor due to gravity is an example of law of gravity. The law of gravity states that objects are attracted to each other due to the magnitude of force acting between these objects. The earth exerts it's own gravitational force, to attract the objects towards itself.
Answer:
The pH of the solution is 3.0
Explanation:
Considering:
Or,
Given :
For
:
Molarity = 0.0030 M
Volume = 100 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 100×10⁻³ L
Thus, moles of
:
Moles of
= 0.0003 moles
Volume added = 200 mL
Total volume = 200 + 100 mL = 300 mL = 0.3 L
Thus,
SInce, it is strong acid. Thus, [H⁺] = 0.001 M
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺] = - log 0.001 = 3.0
<u>The pH of the solution is 3.0</u>
Answer:
Carbon dioxide and Water
Explanation:
In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced
