3. You believe that water boils at 212 degrees Fahrenheit (100 degrees Celsius). Write the numberon the scale from best to worst.
1. Your cousin said that he tested the temperature of water boiling and found that it was 100°C.
2. Most people you know believe that water boils at 100°C.
3. You used a thermometer to measure the temperature at which water boiled. You repeated the experiment 3 times. Each time the thermometer read 100°C.
4. You read an article in a science journal from 50 different labs around the world that have tested the temperature of water and found that it boils at 100°C in every location.
You come across an article in a scientific journal from 50 different laboratories around the globe that measured the boiling point of water and discovered that it is 100°C everywhere.
What transpires when water is heated to 100 C (This is 212 F)?Water turns into gas around 212°F (100°C), which is the temperature at which it begins to boil (water vapor). Pressure affects the melting/freezing and boiling points. Water's boiling point changes when air pressure changes. The boiling point decreases with increasing altitude or decreasing pressure.
At 212 degrees Fahrenheit, does water boil, or at 100 degrees?Water has a freezing point of 32 degrees Fahrenheit and a boiling point of 212 degrees Fahrenheit on the Fahrenheit scale.

what is the molecular shape of N2O2?
Answer:
If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.

Answer:
H2 would have a coefficient of 2.
Explanation:
According to the balanced chemical equation, the coefficient of hydrogen is 4.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

How do we know if molecules have kinetic energy?
28g of aluminum reacts with 45g oxygen
1) complete balanced equation?
2) what is the limiting reactant?
3) how many grams of product could be formed?
4) how many grams of excess would you predict?
5) if you actually measured 50g of product, what is the percent yield?
Answer:
answer below:
Explanation:
1) 4 Al + 3 O2 --> 2Al2O3.
2) Al mol= 28/27 = 1.037mol
O mol= 45/16 = 2.812mol
Al : O
4 : 2
x : 2.812
cross multiply
4 x 2.812/2 = 5.624 mol of Al
Al is limiting reactant
3) 28/5.246 = 5.34product can be formed (not that much sure)
4) 45/ 0.5185 = 86.79
86.79 - 5.34 = 81.45g
5) 50 / 81.45 x 100 = 61.39% ( i guess)

What is the difference between a pure solvent and a solution? Do they have the same physical properties?
Answer:
The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.

Answer:
a. Oxygen
b. 20.39g of Al₂O₃
c. 87%
Explanation:
In order to produce 2moles of Al₂O₃, we need to make react 4 moles of Al, to 3 moles of O₂.
We determine the limiting reactant with the moles of each:
12.98g / 26.98g/mol = 0.481 moles of Al
9.6g / 32g/mol = 0.300 moles of oxygen
4 moles of Al react to 3 moles of O₂
Then, 0.481 mol may react to (0.481 . 3)/4 = 0.361 moles
We only have 0.300 moles of O₂ and we need 0.361. Oxygen is the limiting reactant.
So 3 moles of O₂ can produce 2 moles of Al₂O₃
Our 0.300 moles may produce (0.300 . 2) / 3 = 0.200 mol
Our theoretical yield is: 0.2 mol . 101.96g/ mol = 20.39 g
To determine the percent yield we calculate:
(Produced yield/ Thoeretical yield) . 100 → (17.74 /20.39) . 100 = 87%
