The best example to represent the use of creativity in scientific inquiry is developing a new way to extract a particular protein from tissue samples.

Answer: Option 4

<u>Explanation: </u>

Creativity always leads to invention of new things in any fields. In science, creativity leads to starting of new inquiry or analysis and the results obtained will be new product.

The new product will be helpful to the scientific community and also to people around them. The new product obtained as a resultant of creativity should be economical, useful for society, novel method and finding.

So, among the options given, the last option acts as the best example of creativity in scientific field.

Explain why space junk is a hazard to an astronats or spacecraft
Pie

Answer:

Space junk is travelling so fast that a collision with an astronaut or a spacecraft could be disastrous.

Explanation:

Space junk orbits the Earth at speeds of about 28 000 km/h.  

That's so fast that even an orbiting fleck of paint has enough kinetic energy to cause impact craters on the surface of a spacecraft. They are even more dangerous to an astronaut on a space walk.

Much of the space debris is larger and more dangerous than a fleck of paint.

One rough estimate of the amount of space debris is

<em>       </em><u>Size</u><em>        </em>        <u>Number of objects</u>

< 1 cm                        200 000 000

1 cm to 10 cm                   700 000

> 10 cm                                 30 000

Satellites, etc.                       18 000

The chances of collision are small, but any collision can be disastrous.

A gas evolved during the fermentation of alcohol had a volume of 19.4 L at 17 °C and 746 mmHg. How many moles of gas were collec
AlexFokin [52]

Answer:- 0.800 moles of the gas were collected.

Solution:- Volume, temperature and pressure is given for the gas and asks to calculate the moles of the gas.

It is an ideal gas law based problem. Ideal gas law equation is used to solve this. The equation is:

PV=nRT

Since it asks to calculate the moles that is n, so let's rearrange this for n:

n=\frac{PV}{RT}

V = 19.4 L

T = 17 + 273 = 290 K

P = 746 mmHg

we need to convert the pressure from mmHg to atm and for this we divide by 760 since, 1 atm = 760 mmHg

P=746mmHg(\frac{1atm}{760mmHg})

P = 0.982 atm

R = 0.0821\frac{atm.L}{mol.K}

Let's plug in the values in the equation to get the moles.

n=\frac{0.982atm*19.4L}{0.0821\frac{atm.L}{mol.K}*290K}

n = 0.800 moles

So, 0.800 moles of the gas were collected.
