Answer: Lysosomes

Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

How many liters of carbon dioxide will 0.5 moles of lithium hydroxide (LiOH) absorb?

Elden [556K]

Answer : The volume of carbon dioxide will be, 5.6122 L

Solution : Given,

Moles of LiOH = 0.5 moles

Molar mass of carbon dioxide = 44 g/mole

Density of carbon dioxide = 0.00196 g/ml

First we have to calculate the mass of carbon dioxide.

The balanced reaction will be,

$2LiOH+CO_2\rightarrow Li_2CO_3+H_2O$

From the reaction we conclude that

As, 2 moles of LiOH absorbs 44 grams of carbon dioxide

So, 0.5 moles of LiOH absorbs $\frac{0.5moles}{2moles}\times 44g=11$ grams of carbon dioxide

Mass of carbon dioxide = 11 g

Density of carbon dioxide = 0.00196 g/ml

Now we have to calculate the volume of carbon dioxide.

$Density=\frac{Mass}{volume}$

$0.00196g/ml=\frac{11g}{volume}$

Volume of carbon dioxide = 5612.24 ml = 5.6122 L (1 L = 1000 ml)

Therefore, the volume of carbon dioxide will be, 5.6122 L

If the frequency of an FM wave is 8.85 × 107 hertz, what is the period of the FM wave?

Keith_Richards [23]

NAMASTE

HERE IS YOUR ANSWER:

$\boxed{Frequecy = \frac{1}{time \: period} }$

Frequency (given) = 8.85× ${10}^{7}$ hz

time period =
$\frac{1}{8.85 \times {10}^{7}}$

= 0.112 × ${10}^{-7}$

= 1.12 × ${10}^{-8}$

If 18.1 mLmL of 0.800 M HClM HCl solution are needed to neutralize 5.00 mLmL of a household ammonia solution, what is the molar

AnnyKZ [126]

Answer:

Concentration of ammonia = 3M

Explanation:

The reaction for the question is a neutralization reaction between HCl and NH₃

The chemical equation for the reaction is given as

HCl + NH₃ → NH₄CL

1 : 1 1

Volume of HCl = 18.1ml = 0.0181L

Volume of NH₃ = 5ml= 0.005L

Molar concentration of HCl=0.8M

Molar Concentration of NH₃ =?

Number of moles(n)= Molar concentration × Volume

n = C × V

n of HCL= 0.8 × 0.0181

n = 0.01448moles

Since mole ration for the reaction from the balanced equation above is 1:1,

n of NH₃ = 0.01448

molar concentration (C) of NH₃ = n/v

C of NH₃ = 0.01448/0.005

C of NH₃=2.896

C OF NH₃ =3M
