Is the sky blue on a sunny Tuesday evening
Answer: Yes
Explanation:
It is all to do with the nature of sunlight and how it interacts with Earth's atmosphere.The sun's light appears to be white but it is made up of all the colours of the rainbow. When the light travels through our atmosphere it is scattered in all directions by all the gases and particles in the air.The blue light is scattered more than other colours because it travels in smaller and shorter waves, this is why the most prominent colour in the sky is blue.

In a lab you measure out 0.159 mol of C7H14O7. How many grams should you weight out?
1) find the molar mass of C₇H₁₄O₇.
[tex]=7(12.01)\ +\ 14(1.01)\ +\ 7(16.00)\\\\=84.07\ +\ 14.14\ +\ 112.00\\\\=210.21\ g/mol[/tex]
2) solve using dimensional analysis
[tex]=0.159\ mol\ C_{7}H_{14}O_{7}[/tex] × [tex]\frac{210.21g\ C_{7}H_{14}O_{7}}{mol\ C_{7}H_{14}O_{7}}[/tex]
= 33.42339
= 33.4g C₇H₁₄O₇
What is the mass percentage of O in C₂H₆O₂? Provide an answer to two decimal places.
Answer:
51.61% of O in C₂H₆O₂
Explanation:
First find the total mass: C = 12 , H = 1 , O = 16
total mass of C₂H₆O₂ = 12 * 2 + 1 * 6 + 16 * 2 = 62
so total mass of oxygen, O₂ in this is: 16 * 2 = 32
now find O₂ percentage in C₂H₆O₂⇒ ( 32 / 62 ) * 100
⇒ 51.61%

A lamp has been on for several hours, and its lampshade begins to feel warm. What causes this to happen
If two systems at different temperatures have contact with each other, heat will flow from the system at
1
20°C to a system at 303 K
2
30°C to a system at 313 K
3
40°C to a system at 293 K
4
50°C to a system at 333 K
The heat will flow from the system at 40°C to a system at 293 Kelvin.
Flow of temperatureIf two systems at different temperatures have contact with each other, heat will flow from the system at 40°C to a system at 293 Kelvin because temperatures moves from hotter body to cold body.
ReasonWe know that 293 kelvin is equals to 20° Celsius which is lower than 40° Celsius so the heat energy moves from the body having 40° Celsius temperature to the body having 293 kelvin temperature so we can conclude that the heat will flow from the system at 40°C to a system at 293 Kelvin.

state the oxidation number of S in
[tex]H_{2}SO_{3}[/tex]
thankyou ~
Taking into account the definition of oxidation number, the oxidation numbers of S in H₂SO₃ is 4.
Definition of oxidation numberThe oxidation number is the charge that an atom has; is an integer that represents the number of electrons an atom puts into play when it forms a given compound.
In other words, the oxidation number of an element is a value that indicates the number of electrons that element gains or loses when it combines with another.
Oxidation number determinationTo determine the oxidation state of different elements it is necessary to know that:
The oxidation number of hydrogen in a compound is +1, except in metal hydrides, where is –1.The oxidation number of oxygen in a compound is –2, except in peroxides, where it is –1.On the other side, the sum of the oxidation numbers of the existing elements in a chemical formula must add up to zero.
Then, considering the oxidation numbers of each element, multiplying it by the number of existing elements in the chemical formula and adding it and equaling it to zero, the value of the missing oxidation number can be obtained.
Oxidation numbers of SIn this case, the oxidation numbers of S in H₂SO₃ is calculated as:
2× (+1) + oxidation numbers of S + 3×(-2)= 0
2 + oxidation numbers of S -6= 0
oxidation numbers of S -4= 0
oxidation numbers of S= 4
Finally, the oxidation numbers of S in H₂SO₃ is 4.

Percocet contains oxycodone at varying strengths.Every strength also contains 325 mg of
acetaminophen per tablet.If the dose is not to exceed 3.9g of acetaminophen daily,what
is the maximum number of Percocet tablets a patient can take daily?(unit conversion)
The maximum number of Percocet tablets a patient can take daily, while staying within the recommended acetaminophen dose of 3.9g, is 12 tablets.
To determine the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of 3.9g of acetaminophen, we need to perform a unit conversion.
1. Convert 3.9g to mg (since the amount of acetaminophen per tablet is given in mg): 3.9g = 3900mg
2. Calculate the number of Percocet tablets based on the amount of acetaminophen per tablet: Each Percocet tablet contains 325mg of acetaminophen.
3. Divide the maximum allowable dose of acetaminophen (3900mg) by the amount of acetaminophen per tablet (325mg) to find the maximum number of tablets: 3900mg / 325mg = 12 tablets
Therefore, the maximum number of Percocet tablets a patient can take daily without exceeding the recommended dose of acetaminophen (3.9g) is 12 tablets.

What adaptation does a tufted titmouse have that allows it to stay in a broadleaf forest year-round?
They fluff their feathers for warmth.
They migrate for the winter.
They eat mice for energy to warm themselves.
They hibernate for the winter.
Answer:
They fluff their feathers for warmth.
Explanation:
It was in the explanation on Edge.
Tufted titmouse migrate for the winter that allows it to stay in broadleaf forest year round. Hence, option b is correct.
What is tufted titmouse?The Tufted Titmouse is a little, grey bird with an echoing call that is prevalent in eastern deciduous woodlands and a regular feeder visitor.
These birds have huge black eyes, a short, round beak, and a brushy crest, which give them a peaceful yet urgent appearance that complements the way they dart through trees, dangle from twigs, and land at bird feeders.
Tufted Titmice frequently visit backyard bird feeders, particularly in the winter. Although suet, peanuts, and other seeds are also acceptable, they prefer sunflower seeds.
The tufted titmice live in a variety of environments, such as disturbed areas, semi-open areas, and deciduous and mixed woods. They are a frequent visitor to bird feeders and are prevalent in residential settings with trees. Hence, option b is correct.
