Answer:
the answer is C
Explanation:
This is because group6 elements are diatomic and when they are chemically combined their subscript 2 cancels out
Answer: increase number of collisions
Explanation:
Decreasing the volume increases the likelihood of particles interacting more often.
Answer:
Q1: 2. Molarity.
Q2: 2.51 x 10⁻³.
Explanation:
<u><em>Q1:</em></u>
- The molarity is defined as the no. of moles of solute in one liter of solution.
- It is can be calculated from the relation: M = (no. of moles of solute)/(Volume in L of the solution).
<u><em>Q2:</em></u>
∵ pH = - log[H₃O⁺]
∴ 2.60 = - log[H₃O⁺]
log[H₃O⁺] = -2.6.
<em>∴ [H₃O⁺] = 2.51 x 10⁻³.</em>
<u>Answer:</u>
He should have put the glass in a broken glass bin
<u>Explanation:</u>
Putting broken glasses in the trash can or the dust bin can be hazardous to the workers working at local recycling center as the pieces might hurt them. Instead, he should have thrown the broken beaker in a separate glass bin or should have wrapped properly in paper so that it won't hurt anyone.
Also, glasses have a high melting point and therefore it is not recyclable. Hence, it should be trashed separately.
Releases heat
(Exothermic)
