Answer:

Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. ... Ground-based telescopes can't do the same, because the Earth's atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.

Based on the information given, the private savings will be $10000 and the gross domestic product is $63000.

From the information given, he following can be gotten:

Since, S = Y - C - G

11000 = Y - 48000 - G

Y - G = 48000 + 11000

Y - G = 59000

Budget surplus = T - G = 1000

5000 - G = 1000

G = 5000 - 1000 = 4000

The GDP will be:

Y - G = 59000

Y - 4000 = 59000

Y = 59000 + 4000 = 63000

Private savings = Y - T - C

Private savings = 63000 - 5000 - 48000

Private savings = 10000

The percentage by mass of Na2CO3 in the sample is 48%.

The equation of the reaction of Na2CO3 with HCl;

Na2CO3(aq) + 2HCl(aq) ------> 2NaCl(aq) + H2O(l) + CO2(g)

Since the HCl is in excess, the excess is back titrated with NaOH as follows;

NaOH (aq) + HCl(aq) ---->NaCl(aq) + H2O(l)

Number of moles of HCl added =  0.100 M × 50/1000 L = 0.005 moles

Number of moles of NaOH added = 5.6/1000 ×  0.100 M = 0.00056 moles

Since the reaction of NaOH and NaOH is 1:1, 0.00056 moles of HCl reacted with excess HCl.

Amount of HCl that reacted with Na2CO3 =  0.005 moles -  0.00056 moles = 0.0044 moles

Now;

1 mole of Na2CO3 reacts with 2 moles of HCl

x moles of Na2CO3 reacts with 0.0044 moles of HCl

x = 1 mole × 0.0044 moles / 2 moles

x = 0.0022 moles

Mass of Na2CO3 reacted = 0.0022 moles × 106 g/mol = 0.24 g

Percentage of Na2CO3  in the sample = 0.24 g/ 0.500-g × 100/1 = 48%

Since it is conventional in science to use an average not just a single result, the original average should be used because it came from three results, not just one.

The boiling point refers to the temperature when the pressure of the fluid equals the atmospheric pressure. Hence, boiling occurs at atmospheric pressure.

In scientific experiments, it is common to conduct experiments more than once and obtain an average value for the measurement. In this case, the original average should be used because it came from three results, not just one.

Biocompatibility

Explanation:

I’m a genius and it’s the answer :D

Biocompatibility is a challenge of prosthetic engineering that has been met through tissue engineering. Hence, option B is correct.

Biocompatible materials are used in medical devices, such as menstrual cups, stents, or ventilators.

A biocompatibility problem might happen when some of the materials are trapped in the patient's gingival sulcus.

Tissue engineering is an important field of regenerative medicine for tissue repair (after damaged caused by a disease or an accident, for example).

To offer this possibility, stem cells are important tools owing to their capacity to differentiate into a large number of cells according to the stimuli provided.

Hence, option B is correct.

The number of moles of KMnO4 is  0.0006 moles.

The equation of the reaction is;

6 H^+(аq) + 2 МnO4^- (аq) + 5 Н2С2O4(аq) → 10 CO2 (g) + 8 H20 (l) + 2 Mn²+ (aq)

We can see that the volume of the titrant used = Final - initial burette reading

= 29.6 mL - 3.4 mL = 26.2 mL

Number of moles of H2C2O4 =  0.139 g/90 g/mol = 0.0015 moles

If 2 moles of  MnO4- reacts with 5 moles of H2C2O4

x moles of  MnO4- reacts with 0.0015 moles of H2C2O4

x =  2 moles ×  0.0015 moles / 5 moles

Explanation:

Answer:

Explanation:

The Carnot engine is a theoretical or conceptual heat engine that has a higher efficiency than any practical or theoretical heat engine working between the same temperature range. The theoretical efficiency of a Carnot engine is considered as the highest efficiency and no practical heat engines can operate at that efficiency. A Carnot engine draws heat energy, performs useful work and the leftover energy is released from the working substance. According to the second law of thermodynamics, there must be a temperature gradient between the heat energy drawing point and release point of the heat engine.
