What building should represent the lysosome and why

Chemistry
1 answer:
yaroslaw [1]2 years ago
5 0

Answer:

Food Processing Plant

Explanation:

The lysosomes contain digestive enzymes that break down large food particles into sugars and other simple substances that can be used more easily as does a food processing plant that processes large quantities of food entering the city into smaller packages that can be used more easily.

any time an energy conversion takes place, some of the original energy is converted to which one of the following?
Charra [1.4K]

Answer:

Thermal energy.

Explanation:

Anytime energy transfers between 2 places or things some of it is 'wasted' as thermal energy (heat). This could be by friction or a change in temperature from a reaction. We say it is wasted because this heat energy serves no purpose.

1) When 2.38g of magnesium is added to 25.0cm of 2.27 M hydrochloric acid, hydrogen gas is released.
Andrej [43]

Answer:

a. HCl.

b. 0.057 g.

c. 1.69 g.

d. 77 %.

Explanation:

Hello!

In this case, since the reaction between magnesium and hydrochloric acid is:

Mg+2HCl\rightarrow MgCl_2+H_2

Whereas there is 1:2 mole ratio between them.

a) Here, we can identify the limiting reactant as that yielded the fewest moles of hydrogen gas product via the 1:1 and 2:1 mole ratios:

n_{H_2}^{by\  HCl}=0.025L*2.27\frac{molHCl}{1L}*\frac{1molH_2}{2molHCl}  =0.0284molH_2\\\\n_{H_2}^{by\  Mg}=2.38gMg*\frac{1molMg}{24.3gMg}*\frac{1molH_2}{1molMg}=0.0979molH_2

Thus, since hydrochloric yields fewer moles of hydrogen than magnesium, we realize it is the limiting reactant.

b) Here, we use the molar mass of gaseous hydrogen (2.02 g/mol) to compute the mass:

m_{H_2}=0.0284molH_2*\frac{2.02gH_2}{1molH_2}=0.057gH_2

c) Here, we compute the mass of magnesium associated with the yielded 0.0248 moles of hydrogen:

m_{Mg}^{reacted}=0.0284molH_2*\frac{1molMg}{1molH_2}*\frac{24.3gMg}{1molMg}  =0.690gMg

Thus, the mass of excess magnesium turns out:

m_{Mg}^{excess}=2.38g-0.690g=1.69gMg

d) Finally, we compute the percent yield, considering 0.044 g is the actual yield and 0.057 g the theoretical yield:

Y=\frac{0.044g}{0.057g} *100\%\\\\Y=77\%

Best regards!

"sodium hydroxide is a strong base because it absorbs more" ____________ ions than weak bases.
Hunter-Best [27]
The answer is: absorbs more H (protons) ions.

- The Sodium hydroxide NaOH ionizes completely when dissolved in water.
- For every mole of sodium hydroxide that you dissolve you get 1 mole of hydroxide anions.

Acid rain can be destructive to both the natural environment and human-made structures. The equation below shows a
guapka [62]

Answer:

A

Explanation:

What the equation is tell you is that for every 3 mols of NO2 you get 2 mol of HNO3

3 mol NO2 / 2 mol HNO2 ===> 300.00 mol NO2 / x   Cross multiply

3x = 2 * 300

3x = 600                 Divide by 3

3x/3 = 600/3           Do the division

x = 200.00
