Answer:NSAIDs work on a chemical level. They block the effects of special enzymes -- specifically Cox-1 and Cox-2 enzymes. These enzymes play a key role in making prostaglandins. By blocking the Cox enzymes, NSAIDs stop your body from making as many prostaglandins.

Answer:
![\boxed{\text{b) reduction potential less than that of oxygen}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7Bb%29%20reduction%20potential%20less%20than%20that%20of%20oxygen%7D%7D)
Explanation:
Electrochemical corrosion of a metal is its spontaneous reaction with oxygen.
Let's compare the standard reduction potentials for a hypothetical metal M with that of oxygen.
<u>E°/V</u>
O₂(g) + 2H₂O(ℓ) + 4e⁻ ⇌ 4OH⁻(aq) 0.4
M²⁺(aq) + 2e⁻ ⇌ M(s) -0.1
To react spontaneously with O₂, the metal must have a ![\boxed{\textbf{reduction potential less than that of oxygen}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctextbf%7Breduction%20potential%20less%20than%20that%20of%20oxygen%7D%7D)
<u>E°/V
</u>
2 × [M(s) ⇌ M²⁺(aq) + 2e⁻ ] 0.1
1 × <u>[O₂(g) +2H₂O(ℓ) + 4e⁻ ⇌ 4OH⁻(aq)] </u> <u>0.4
</u>
2M(s) + O₂(g) + 2H₂O(ℓ) ⇌ 2M²⁺(aq) + 4OH⁻(aq) 0.5
Only then will we get a positive for the overall cell potential and a spontaneous reaction.
Answer:
Graduated cylinder
Explanation:
Fun tip: 1 g of water is equal to 1ml
Answer:
109.94 g/mol
Explanation:
Li is 6.94 and there's 2 of those = 13.88
1 S = 32.06
4 O = 63.996
Add all of those together to get 109.936 round to 109.94
it is a great change because the salt goes in and turn the water to salt water
