How is living in space different from living on Earth?

Answers

Answer 1

Answer:

The three major differences are: atmosphere (vacuum in space), radiation (high level of dangerous particles), and gravity (weightlessness in space). The first difference between the Earth and space is the atmosphere.Jan

The only significant differences from living on Earth are that they operate in the confined space of the Space Shuttle orbiter cabin and that they, and all objects inside the cabin, float.

Answer:

DBE

Explanation:

Cause I got it right

The correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.

Charles's law states that, under the assumption of constant pressure, the volume of a gas increases or decreases with its temperature. As the temperature increases, the gas molecules move more quickly and occupy more space, increasing the volume of the gas.

Gay-Lussac's law states that, assuming a constant volume, the pressure and temperature of a gas are exactly related. Increasing temperature causes the gas molecules to become more kinetically energetic and collide with the walls of the container more frequently, increasing the pressure.

Boyle's law states that at a given temperature, the pressure and volume of a gas are inversely proportional. The reduced volume forces the gas molecules into a smaller area, increasing the chance of collisions with the container walls and pressure.

Therefore, the correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.

Which substance is one that cannot be separated or broken down into simpler substances by chemical means? (Element, pure)

table salt (NaCl)
gold wire (Au)
candle wax (CH2O)
water vapor (H2O)

Answers

Answer:

gold wire (Au)

Explanation:

A substance that cannot be separated or broken down into simpler substances by chemical means is an element.

Between the given options only gold wire is an element, Au.

A way of knowing that it is an element is noticing that its formula is a single symbol which corresponds to an element found in the periodic table, unlike a combination of said symbols (like NaCl or H₂O).

The student recorded the mass of the cup + sample incorrectly and started with 2.20 g of hydrated compound but used 2.00 g in the calculations. Explain how this error will affect the calculation for the number of moles of water in the hydrate? Will the final answer be artificially high or low? How do you know?

Answers

Answer:

low

Explanation:

We were informed in the question that the student had incorrectly recorded the mass of cup + sample as 2.20 g but inadvertently used 2.00 g in the calculations.

This error will cause a slight decrease in the mass of water and ultimately decrease the number of moles of water in the hydrate.

What i am saying is that the number of moles of water obtained in the calculation will be artificially low.

What is metallic element ?

Except for hydrogen, which is a nonmetal, the elements are arranged in a triangle with the metals to the left, the nonmetals to the right, and the metalloids to the immediate right of the triangle.

Metal atoms are bound together by metallic bonds to form solids known as metallic solids. Metal solids include things like copper, gold, and zinc, for instance. Since cesium is the last naturally occurring alkali metal, it has the most metallic characteristics.

The non-metal components, like as rock and rubbish, are subsequently removed from the ore during processing. The subsequent melting and combining of various metal components yields metal alloys. A solid metal alloy substance is produced when the freshly combined metal compound has cooled.

Thus, option C is correct.

There are two isotopes of an unknown element, X-19 and X-21. The abundance of X-19 is 14.55%. A weighted average uses the percentages of each isotope to scale their contribution to the total mass. Each isotope's contribution is the percentage (in decimal form) multiplied by the mass of the isotope. What is the contribution (in amu) to the weighted average from the X-19 isotope, which has a mass of 19.00 amu

Answers

Answer:

2.765amu is the contribution of the X-19 isotope to the weighted average

Explanation:

The average molar mass is defined as the sum of the molar mass of each isotope times its abundance. For the unknown element X that has 2 isotopes the weighted average is defined as:

X = Mass X-19 * Abundance X-19 + MassX-21 * Abundance X-21

The contribution of the X-19 isotope is its mass (19.00 amu) times its abundance (14.55% = 0.1455). That is:

19.00amu * 0.1455 =

Rank from highest to lowest viscosity, surface tension, and boiling point.

Answers

Answer:

Following are decreasing order to this question:

Explanation:

Viscosity and surface tension both are inter-molecular by nature (IMFs)

The pentane becomes non-polar and just not H-bondable, so LDF alone would be likely (London Dispersion Force)

Pentanal, but H-bond => is impossible (Dipole-Dipole)

Pentanol is also an OH group, so H-bond => is probable (Hydrogen Bonding)

5.6 g of an organic compound on burning with excess
of oxygen gave 17.6 g of CO2, and 7.2 g of H,O. The
organic compound is :​

Answers

Answer:organic compound is :​ C₄H₈

Explanation: The equation of the reaction of the organic compound burning with excess oxygen gives us the general equation as

C xHy  + 1/2(x+ y/2 )O₂ → xCO₂ + y/2H₂O

We first find the number of moles of CO₂ and H₂O

Number of moles of CO₂= Mass/ molar mass

= 17.6g/ 44g/mol ( 12+ 16 x2)

=0.4 moles

Number of moles of H₂O= Mass/ molar mass

= 7.2g/ 18g/mol ( 1 X 2+ 16)

=0.4 moles

From the reaction , we can see that  

x = 0.4

and  [tex]\frac{y}{2}[/tex]= 0.4  such that y= 0.4 x 2= 0.8

Their ratios become

[tex]\frac{x}{y}[/tex] =[tex]\frac{0.4}{0.8}[/tex]= [tex]\frac{4}{8}[/tex]

Therefor the organic compound CxHy  = C₄H₈

The reaction for luminol is basically luminol and hydrogen peroxide. In the instructions for the preparation of the chemicals, I found that the hydrogen peroxide is 44 times more concentrated than the luminol. The fact that there are two reactants, should make you wonder if the reaction is second order overall. However, in class, we presented data that showed that the natural log of the amount of light change over time was a straight line with a negative slope. This would tend to make you think that the reaction is first order, given the information here, you can confidently say that this reaction is:
A. zeroth order
B. first order
C. pseudo first order
D. second order
E. third order

Answers

Answer:

pseudo first order

Explanation:

We know that for a first order reaction, the plot of the natural log of the amount of reactant against time is a straight line with a negative slope. In this case the amount of substance is monitored using the amount of light change. Hence, the plot of the natural log of the amount of light change against time was a straight line with a negative slope.

The statement above characterizes a first order reaction. However, we must remember that the reaction is bimolecular; it involves luminol and hydrogen peroxide. The hydrogen peroxide is 44 times more concentrated than the luminol making the reaction a pseudo first order reaction.

A Pseudo first-order reaction can be defined as a second-order or bimolecular reaction that is made to behave like a first-order reaction(Byjus).

How to make 0.01 Molar solution in 30 ml of water

Answers

Answer:

You see the concentration decreased ten fold, from 1 M to 0.1 M.

You can simply increase the volume by ten times.

For example

If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.

If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.

C1 = starting concentration.

C2 = final concentration.

V is for volume.

So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.

1 M x V1 = 0.1 M x 50 mL

V1 = 5 mL

So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.

Mass of hydrated copper sulfate in CuSo4.5H2O​

Answers

Answer: Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.

Explanation:

Molar mass is the mass of 1 mole of the molecule. It is calculated by adding masses of all the atoms in the given molecule.

[tex]CuSO_4.5H_2O[/tex] contains one atom of copper , 1 atom of sulphur, 9 atoms of oxygen and 10 atoms of hydrogen

Mass of copper = 63.5  g/mol

Mass of sulphur =  32.06 g/mol

mass of oxygen = 16.00 g/mol

Mass of hydrogen = 1.008 g/mol

 Thus mass of [tex]CuSO_4.5H_2O[/tex] = 63.5(1)+32.06(1)+16.00(9)+1.008(10)=249.68 g

Molar mass of [tex]CuSO_4.5H_2O[/tex] is 249.68 g/mol.
