According to enstiens theory of relativity, c is constant in E=mc^2 c is the speed of light. and many other physicsts all calculate it to be the same amount, <span>299,792, 458 meters per second. </span>
Answer:
Aluminium Chloride and Hyrdron, also known as proton/
Explanation:
Volcanoes are formed when hot molten rock, ash, and gases escape from an opening in the Earth's surface. This could happen when the tectonic plate moves under one another, creating an opening. Over the years more layers pill up creating the hard layer of the volcano.

Answer:
a. 1 mole of acid is equal to one equivalent.
b. 1.00 moles of HCl are found.
c. 1L of 2.00M NaOH is needed to reach the equivalence point
Explanation:
HCl reacts with NaOH as follows:
HCl + NaOH → NaCl + H2O
<em>Where 1 mole of HCl reacts with 1 mole of NaOH. The reaction is 1:1</em>
a. As the reaction is 1:1, 1 mole of acid is equal to one equivalent
b. The initial moles of HCl are:
1.00L * (2.00moles HCl / 1L) = 2.00 moles of HCl
At the halfway point, the moles of HCl are the half, that is:
1.00 moles of HCl are found
c. At equivalence point, we need to add the moles of NaOH needed for a complete reaction of the moles of HCl. As the moles of HCl are 2.00 and the reaction is 1:1, we need to add 2.00 moles of NaOH, that is:
2.00moles NaOH * (1L / 2.00mol) =
1L of 2.00M NaOH is needed to reach the equivalence point
