Chemical Equation Balancer
Answer:
I'm pretty sure that it gains 2 electrons
Answer:
Mark me brainliest
Explanation:
Standards help avoid confusion and ambiguity when taking measurements. For example, a meter will always be the same length, no matter who is taking the measurement or where it is being taken.
Answer:
Student 4, because a Brønsted-Lowry base always accepts a proton from an acid to form a conjugate acid.
Explanation:
That's the definition of a Brønsted-Lowry base.
Student 2 is wrong. All bases will neutralize acids. That doesn't tell you the type of base.
Student 3 is wrong. The pH of a solution doesn't tell you the type of base.
Student 1 is wrong. Both Arrhenius and Brønsted-Lowry bases react with acids to produce water and a salt.
Answer:
0.15 M KCl
Explanation:
(Step 1)
Convert the original volume from mL to L. Calculate the moles of the original solution.
75.0 mL / 1,000 = 0.0750 L
Molarity = moles / volume (L)
0.200 M = moles / 0.0750 L
0.0150 = moles
(Step 2)
Convert the final volume from mL to L. Calculate the final molarity.
100. mL / 1,000 = 0.100 L
Molarity = moles / volume (L)
Molarity = 0.0150 moles / 0.100 L
Molarity = 0.15 M
