1. since Beatrice is applying force to the box, she is doing work
2. formula is work = force x displacement
3. displacement = 2 meters, force = 40 N
work = 40 x 2 = 80 Joules
That looks like helium
since it has 2 protrons, neutrons, and electrons.
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.
Explanation:
Answer:
Molarity = 1 mol.L⁻¹
Solution:
Molar concentration (Molarity) is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Moles = 4 mol
Volume = 4 L
Putting Data in Eq. 1,
Molarity = 4 mol ÷ 4 L
Molarity = 1 mol.L⁻¹
Answer: -
Baking soda having a pH of 9, has the maximum number of hydroxide ions.
Explanation: -
More the pH of a solution, the more basic it is and more the number of hydroxide ions it has.
From the question we find that
baking soda has a pH = 9
milk has a pH = 6
tomato juice has a pH = 3.5
vinegar has a pH = 2
Thus among them baking soda has the highest pH.
So baking soda is the most basic and has the maximum number of hydroxide ions.
