A mixture is made by combining 1.62 lb of salt and 5.20 lb of water.
WINSTONCH [101]

Answer:

23.8

Explanation:

Formula

weight % = weight of solute/ weight of solution x 100

weight of solution = weight of salt + weight of water

weight of solution = 1.62 lb + 5.20 lb = 6.82 lb

weight % = 1.62 / 6,82 x 100

weight % = 0.238 x 100

weight % = 23.8

2. C  The answer convection because the heat was transferred through a medium (liquid/gas).

3. A  The answer is conduction because the heat was transferred through direct contact.

4. C  The answer is radiation because the heat was transferred through thermal emission.

5. True.  This is because the air that is warmed rises, causing the cool air to replace it.  You can picture it like the scenario in question 2.

Como se mencionó en la pregunta, un catalizador aumenta la velocidad de una reacción pero él mismo no participa en la reacción.

La descomposición del peróxido de hidrógeno se muestra mediante la ecuación;

2H2O2 (l) ------> 2H2O (l) + O2 (g)

La enzima involucrada en el proceso es la catalasa.

</span>c₀ - initial amount of C-14.<span>
c - amount of C-14 remaining at time.
t = 5700</span> y.<span>
First calculate the radioactive decay rate constant λ:
λ = 0,693 ÷ t = 0,693 ÷ 5700</span> y = 0,000121 1/y = 1,21·10⁻⁴ y.
c = c₀·e∧-λ·t.
c = 2000 · e∧-(0,000121 1/y · 17100 y).
c = 252 g.
ω = 252 g ÷ 2000 g = 0,126 = 12,6%.
