Answer: Option A
Explanation: 2 Na + Cl2---> 2NaCl
Here Oxidation no of Na is zero while in NaCl is +1. That means oxidation state of Na increased from 0 to +1 hence oxidation
While Cl2 has zero in molecular form and -1 in NaCl hence Reduction (Oxidation no decreased from zero to -1)
Halogens(cl) always shows -1 oxidation state and IA group elements(Na)shows +1 oxidation state
Answer:
0.77 M
Explanation:
Molarity is the concentration of a solution per liter
C= concentration
n= number of moles
V= volume of solution
The formula we will use is C= n/V
C= n/V
C= (1.93 mol NaCl)/(2.5 L of solution)
C= 0.772 mol/L
Since this concentration is given in moles per liters of a solution, this concentration is also the molarity.
C= 0.772 mol/L
*Include two significant digits in final answer*
M= 0.77 M
Answer:
B if they run out of fuel then they would probably keep going because there is nothing that would stop them other than like a planet or something.
Explanation:
Answer:
6
Explanation:
The given reaction is aluminium with hydrochloric acid
2Al + 6HCl → 2AlCl3 + 3H2
the product is aluminium chloride and hydrogen gas.
We can clearly, calculate that there are 2*3=6 chlorine atoms in product side of the reaction.
Your answer would be 753,000 gallons of water
