How would an astronomer identify our home in the universe? Earth is in the solar system. The Milky Way is in the solar system. The solar system is next to the Milky Way. Earth is in the Milky Way and next to the solar system. The Milky Way is in the universe. The solar system is in the Milky Way. Earth is in the solar system. The universe is in the Milky Way. The Earth is in the Milky Way. Earth is at the center of the solar system.

Answers

Answer 1

Answer:

Earth is in the solar system.

Explanation:

Earth is our home and it is in the solar system.

Earth is the fifth-largest of the planets in the solar system and the third planet from the sun. Earth is the only planet having oxygen and water that supports life. Till now according to the research Earth is the only planet having life.

Planets are in the solar system, the solar system is in the milky way and the milky way is present in the universe. The astronomer identifies our home in the universe as "Earth is in the solar system" as Earth is our home.

Hence, the correct answer is "Earth is in the solar system."

Answer 2

Answer:

The Milky Way is in the universe. The solar system is in the Milky Way. Earth is in the solar system.

Explanation:

If the Milky Way Is in the universe and solar system you would know earth is also In the solar system, so "Our home planet is the third planet from the Sun, and the only place we know of so far that's inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface."

We are doing a lab and I have trouble doing the data analysis. Using my data collection, Can you guys help me using the MC delta T equation?

Answers

The equation

4.94 x c . (Tm-23.6)=C.(23-6-21.9)+123.13 x c. (23.6-21.9)

Further explanation

The law of conservation of energy can be applied to heat changes, ie the heat received/absorbed is the same as the heat released  

Q in = Q out  

Heat can be calculated using the formula:  

Q = mc∆T  

A calorimeter is a device used to measure the specific heat of material  

A metal is put into a calorimeter that contains water and there will be heat transfer:  

[tex]\tt \displaystyle m_mc_m (T_m-T)=m_wc_w(T-Tw)[/tex]

m = metal  

w = water  

T = the final temperature of the mixture  

mass of metal =(Nickel) = 4.94 g

mass of calorimeter = 12.5 g

mass of water = 123.13 g (135.63 - 12.5)

The equation

Q released (metal) = Q absorbed(calorimeter+water)

Qmetal = 4.94 x c . (Tm-23.60)Q calorimeter = C.(23-6-21.9) --> C = heat capacity of calorimeterQ water = 123.13 x c. (23.6-21.9)

The equation :

4.94 x c . (Tm-23.6)=C.(23-6-21.9)+123.13 x c. (23.6-21.9)

You will learn in this course that organic compounds have covalent bonds with a significant amount of energy stored in them. This is why we burn fossil fuels to generate energy to heat our homes or drive our cars. Given this information, which of the compounds listed below would you expect to have the most energy is its carbon-carbon bond?

Answers

Answer:

See explanation

Explanation:

This question is obviously supposed to be a multiple choice question but the options are missing.

However, the question intends to test the student's knowledge about combustion of fossil fuels. Fossil fuels are mostly composed of hydrocarbons of different chain lengths.

The longer the chain length, the greater the energy released when the compound is burnt since there are more energy stored in its bonds.

Hence, the correct answer to this question will be the option that contains the greatest number of C-C and C-H bonds.

What is the last energy level of N? Mg?

Answers

Answer:

2

3

Explanation:

To infer the last energy of the given atoms, we need to write their electronic configuration:

For N = 1S² 2S² 2P³

     Mg  = 1S² 2S² 2P⁶ 3S²  

The energy levels are usually designated as;

   n = 1

   n = 2

   n = 3

   n =4

For N, the last energy level is 2

     Mg, the last energy level is 3

We can also determine this number by the periods the atoms can be found.

A.
Volume affects the rate that instant tea dissolves in a solvent.
B.
Temperature affects the rate that instant tea dissolves in water.
C.
Stirring affects the rate that instant tea dissolves in water.
D.
Pressure affects the rate that instant tea dissolves in water.

Please answer my question!

Answers

Answer:

B

Explanation:

In this question, there is no mention of pressure, so we can eliminate answer D. In both cups, it mentions they contain 250 mL of water and both are stirred, so these would be constants. The only difference between the cups is temperature, so temperature must affect the rate that instant tea dissolves in water. Therefore the answer is B.

A metal object has a density of 2 g/ml. When placed in a graduated cylinder with 500 ml of water, the
water rises to 508 ml. What is the mass of the metal object?

Answers

Answer:

The answer is 16 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 2 g/ml

volume = final volume of water - initial volume of water

volume = 508 - 500 = 8 mL

We have

mass = 2 × 8

We have the final answer as

16 g

what is 1.23 x 10^-3 in standard notation

Answers

Answer:

=0.00123

Explanation:

Look at the attachments below

Hope this helps (:

Answer:

0.00123

Explanation:

Standard notation is the normal way of writing numbers. Examples include 1, 2, and 10. The number 1.23 x 10^-3 is written in scientific notation. The decimal goes after the first nonzero integer and it is multiplied by a power of 10. The power or exponent attached to the 10 tells you how many places over you need to move the decimal to get back into scientific notation. Examples include 1.00 x 10^2 (representing 100 in standard form because you would move the decimal two places to the right.), 2.0 x 10^1 (representing 20 in standard form because you would move the decimal one place to the right), and 3.0 x 10^-4 (representing 0.0003 in standard form because you would move the decimal four places to the left since it is a negative exponent).

The negative (-3) exponent in 1.23 x 10^-3 indicated to move the decimal three places to the left. If it was positive, you would move it three places to the right.

In 1.23 x 10^-3 move the decimal to the left 1 place to get:

0.123

two places to get:

0.0123

and a third place to get:

0.00123

The final answer is 0.00123

1. Using a triple beam balance and a graduated cylinder, a student collected data on a sample of an
element:
Mass of sample - 67.9 g
Volume of water - 52.0 ml
Volume of water and sample - 28.0 ml
a) Calculate the density of the sample. Show all work and use significant figures and units.

Answers

Answer:

d = 2.8 g/mL

Explanation:

Given data:

Mass of sample = 67.9 g

Volume of water = 28.0 mL

Volume of water + sample = 52.0 mL

Density of sample = ?

Solution;

Density is equal to the mass of substance over volume of substance.

Formula:

d = m/v

d = density

m = mass

v= volume

Now we will calculate the volume of sample.

Volume of sample = (volume of water+ sample) - volume of water

Volume of sample = 52.0 mL - 28.0 mL

Volume of sample = 24.0 mL

Now we will calculate the density.

d =67.9 g /24.0 mL

d = 2.8 g/mL
