work too pls !! thank you so much !!!
Answer:
Explanation:
We shall use gas law as follows
P₁ V₁ / T₁ = P₂ V₂ / T₂
5 ) V₁ = 20 , P₁ = 88.89 , T₁ = 273+ 67 = 340 K .
V₂ = 12 , P₂ = ? , T₂ = 273+ 94 = 367 K .
88.89 x 20 / 340 = P₂ x 12 / 367
P₂ = 159.9 atm .
6 )
V₁ = ? , P₁ = .5 , T₁ = 325 K .
V₂ = 48 , P₂ = 900/760 = 1.184 , T₂ = 320 K .
V₁ x .5 / 325 = 48 x 1.184 / 320
V₁ = 115.44 litres .
7 )
V₁ = 21 , P₁ = 78 , T₁ = 800 K .
V₂ = ? , P₂ =45 , T₂ = 750 K .
21 x 78 / 800 = V₂ x 45 / 750
V₂ = 34.125 litres .
8 )
V₁ = 3.9 , P₁ = 5 x 10⁵ Pa , T₁ = 323 K .
V₂ = 2.4 , P₂ =3.03 x 10⁵Pa , T₂ = ? .
3.9 x 5 x 10⁵ / 323 = 2.4 x 3.03 x10⁵ / T₂
T₂ = 120.45 K
= -152.54⁰C .
9 )
V₁ = ? , P₁ = 60 , T₁ = 115 K .
V₂ = 25 , P₂ =30 , T₂ = 225.
V₁ x 60 / 115 = 25 x 30 / 225
V₁ = 6.39 litre .
How does a lightning rod protect a
building from lightning damage?
Answer:
The lightning rod attracts lightning and is not connected to any other pieces of metal that may harm any electrical circuits.
Explanation:
I hope this helps, I tried my best to explain it quickly for you.
Answer/Explanation:
A lightning rod is a metal rod that is used to dislocate where lighting hits. Lightning is going to hit the closest point that it has been attracted too. So, the lightning rod was invented to attract lighting to something less potentially dangerous. Instead of hitting a building causing fires and collapsing, it takes the bolt so that nothing else has to.

the Elements have what properties in common?
Answer:
have one delocalised electron
Explanation:
The elements which are present of left side of periodic table have similar chemical properties.
What is periodic table?Periodic table is a tabular arrangement of elements wherein elements are arranged according to their atomic numbers. It consists of seven horizontal rows called periods and eighteen vertical columns called groups .
Elements in the same group have similar chemical properties as they have same number of valence electrons. While, electrons in the same period have different valence electrons as electrons are added to same shell and hence have a little variation in chemical properties.
It is called periodic as properties repeat after an interval of certain electronic configuration. Elements are divided in four blocks depending on their properties.

An element containing a charge.
Answer:
That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge
Answer: The Charge of Elements
For example, sodium is an element with 11 protons within the nucleus and 11 electrons. Another example of an element is carbon, which has six protons within the nucleus and six electrons. In both cases, these elements have a neutral charge.
Explanation: That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
How many moles of oxygen are required for the combustion of 35.5 g of Magnesium Mg+O2-->MgO Please balance
Answer:
0.74 moles of oxygen are required for combustion
Explanation:
Given data:
Number of moles of oxygen required = ?
Mass of Mg = 35.5 g
Solution:
Chemical equation:
2Mg + O₂ → 2MgO
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 35.5 g/ 24 g/mol
Number of moles = 1.48 mol
Now we will compare the moles of Mg with oxygen.
Mg : O₂
2 : 1
1.48 : 1/2×1.48 = 0.74 mol
0.74 moles of oxygen are required for combustion.

atoms was determined to be 143 picometers. What is the percent error of this measured
value?
A) 0.10%
B) 9.1%
C) 10.%
D) 13%
Since the actual value of the atomic radius of platinum atoms was not given in the problem, I chose 175 pm which gives an error of 18.28%.
The actual atomic radius of platinum atoms is 175 pm
We can see from the question that the measured value of the atomic radius of platinum atoms was determined to be 143 pm.
Recall that;
Percent error = Absolute value of (measured value - actual value)/actual value * 100
Since the actual value of the atomic radius was not given, let us take it to be 175 pm for the purpose of this problem
Percent error = Absolute value of (143 - 175)/175 * 100
Percent error = 18.28%
Learn more: https://brainly.com/question/4170313
The percent error of this measured value ; ( D ) approximately 13%
The percent error of a measured value
= [ ( actual value - measured value ) / ( actual value ) ] * 100
= [ ( 175 pm - 143 pm ) / ( 175 pm ) ] * 100
= 18.29%
From the options given the closest value to the calculated value is 13%
Hence we can conclude that the percent error of this measured value is approximately 13%.

[tex]\huge\boxed{Buoyant Force}[/tex]
_____________________________________ARCHEMEDIS LAW (EUREKA)A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces. If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body. That is how we find the Volume of the Irregularly shaped objects.
_____________________________________FUN FACT:Archemedes the GREAT GREEK PHYSICIST was in a real problem finding out the formula of how to find the volume of irregular object. After countless failures in finding it, once he was going to get a apparently "BUBBLE BATH", So when he got into the tub the water displaced and got out from the tub resulting in the splash of water. His MIND CLICKED that we could find the volume by submerging the irregular object into the measured water and then substract the displaced water from it. He ran NAKED out of the house because of the happiness saying EUREKA! EUREKA! which literally means "I have found it". Thus this law of Archemedes is also called EUREKA LAW. So to simply remember how to find volume of irregular object keep EUREKA in mind.
