In this reaction, water acts as the base and donates a proton to hydrazine (H2NNH2). Hydrazine becomes protonated: [N2H5]<span>+ And thus hydrazine in this reaction is actually a base. The conjugate base of the acting acid H2O is OH- (hydroxide ion).</span>
Answer:
I do not know the Answer I'm just trying to get my point
Explanation:
Thank you
I believe the answer is D. An ion always has a positive or a negative charge. An Ion is an atom with net electric charge due to the loss or gain of one or more electrons. An isotope is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their neutron, thus they differ in relative atomic mass but not in chemical properties.
Answer:
Molarity = 1.23 M
Explanation:
Given data:
Molarity of NaCl = ?
Mass of NaCl = 89.94 g
Volume of solution = 1249 mL ( 1249/1000 = 1.249 L)
Solution:
First of all we will calculate the number of moles of NaCl.
Number of moles = mass/molar mass
Number of moles = 89.84 g/ 58.5 g/mol
Number of moles = 1.54 mol
Molarity:
Molarity = Number of moles of solute / volume of solution in L
Molarity = 1.54 mol / 1.249 L
Molarity = 1.23 M
D is the correct answer! YAYYYYYYAA!!
