Answer:
0.429 M
Explanation:
To find the molarity, you need to (1) convert grams to moles (using the molar mass), then (2) convert mL to L, and then (3) calculate the molarity (using the molarity ratio).
(Step 1)
Molar Mass (NaCl): 22.990 g/mol + 35.453 g/mol
Molar Mass (NaCl): 58.443 g/mol
18.8 grams NaCl 1 mole
-------------------------- x ------------------------ = 0.322 moles NaCl
58.443 grams
(Step 2)
1,000 mL = L
750.0 mL 1 L
------------------ x ----------------- = 0.7500 L
1,000 mL
(Step 3)
Molarity (M) = moles / volume (L)
Molarity = 0.332 moles / 0.7500 L
Molarity = 0.429 M
Location D. bc it’s the highest percentage at 88% then it would be A,C,B
The answer of your question is 32.8551
The answer is A
Explanation;
At the start of the reaction, when we first put magnesium in the hydrochloric acid, there is 100% of the magnesium to react with. As a result there will be more successful collisions between the reactant particles. The more successful collisions, the faster the reaction will be.
Answer:
C. Parasitism
Explanation:
Mutualism means both organisms benefit. An example of this is a bee and flower.
Commensalism means one organism benefits and the other is unaffected. An example of this is a whale and barnacles.
Parasitism means one organism benefits, and the other is harmed. An example of this other than mosquito and human is a dog and fleas.
Hope this helps!!
