In your own words, explain a crucial piece of evidence that Johannes Kepler could have used to support one of his laws of planetary motion.

Answers

Answer 1

Answer: Johannes Kepler could have used Evidence gathered by "Tycho Brahe" on the detailed positions of Mars in the sky. He used his entire data, plus Newton's view of observation, then he formulated his law of Planetary motion

Say you had another object of the exact same material as the previous question. You need to know the volume but the object is irregularly shaped and is much too large for graduated cylinder. However, you know that the mass is 382 g. What is the volume of the object?

Answers

Answer:

152.8 cm3

Explanation:

We are given that the material of the object is the same as the previous object

In the previous question, we determined the density of the material is 2.5 g/cm3

We are given the mass of this object is 382 g

To find the volume, we can use the equation:

Mass = Density x Volume

Plugging in the values we know:

382 g = (2.5 g/cm3) x Volume

Solving for Volume:

Volume = Mass / Density

= 382 g / 2.5 g/cm3
= 152.8 cm3

Mendeleev is the scientist who first developed the atomic model

the periodic table

Answers

Dmitri Mendeleev is the scientist who first developed the periodic table.

He is a Russian chemist and inventor who formulated the periodic law and created the periodic table of elements. He corrected some of the properties of the elements. Now, we can easily locate the elements we wanted to identify. With the help of Mendeleev, studying chemistry is not that difficult because he tried to simplify some of the concept that was complex before.

A helium-ﬁlled balloon contains 130 mL of gas at a pressure of 0.97 atm. What volume will the gas occupy at standard pressure?

Answers

Boyle's Law
G: V1= 130 mL
P1= 0.97 atm P2= 1 atm (standard pressure)

U: V2=?
F: V2 = V1 P1/P2
S: V2 = (130 mL) (0.97 atm) / 1 atm
Answer : V2 = 126.1 mL volume of the gas occupy @ STP

"A sphere of radius 0.50 m, temperature 27oC, and emissivity 0.85 is located in an environment of temperature 77oC. What is the net flow of energy transferred to the environment in 1 second?"

Answers

Explanation:

It is known that formula for area of a sphere is as follows.

A = $4 \pi r^(2)$

= $4 * 3.14 * (0.50 m)^(2)$

= 3.14 $m^(2)$

$T_(a)$ = (27 + 273.15) K = 300.15 K

T = (77 + 273.15) K = 350.15 K

Formula to calculate the net charge is as follows.

Q = $esA(T^(4) - T^(4)_(a))$

where, e = emissivity = 0.85

s = stefan-boltzmann constant = $5.6703 * 10^(-8) Wm^(-2) K^(-4)$

A = surface area

Hence, putting the given values into the above formula as follows.

Q = $esA(T^(4) - T^(4)_(a))$

= $0.85 * 5.6703 * 10^(-8) Wm^(-2) K^(-4) * 3.14 * ((350.15)^(4) - (300.15)^(4))$

= 1046.63 W

Therefore, we can conclude that the net flow of energy transferred to the environment in 1 second is 1046.63 W.

A reaction starts with 20.0 grams of lithium hydroxide (LiOH) and produces 31.0 grams of lithium chloride (LiCl), what is the percent yield of lithium chloride (LiCl)? *LiOH + KCl - LiCl + KOH

A) 64.5%
B) 88.6%
C) 81.5%
D) 92.8%

Answers

Answer:

B) 88.6%

Explanation:

Percent yield equals actual yield divided by theoretical yield

actual yield is 31.0g

theoretical yield is 35g

percent yield was 88.57 which rounds up to 88.6%
