Answer: If the Sun had an even greater mass then it currently does, it would have a larger gravitational pull and since it's heat would be closer to Earth, both by magnitude and gravity, life on Earth wouldn't be possible and life on Mars would be reality. Also, when the sun would explode, it would have a larger supernova and possibly create a white dwarf (something that only happens to red supergiant stars when they die), with a gravitational force so strong it wold have two beams of light coming out it's north and south poles (like a black hole).
I hope this helps!
Answer:
1.
Explanation:
Hello,
In this case, for the given reaction we first assign the oxidation state for each species:

Whereas the half reactions are:

Next, we exchange the transferred electrons:

Afterwards, we add them to obtain:

By adding and subtracting common terms we obtain:

Finally, by removing the oxidation states we have:

Therefore, the smallest whole-number coefficient for Sn is 1.

The element "X" is "O" (oxygen).
<h3>Calculation:</h3>
Given,
Chemical formula = Na₂CX₃
Formula mass = 106 amu
Molar mass of Na = 23 amu
Molar mass of C = 12 amu
To find,
Element X =?
We will equate the equation as follows,
2(23) + 12 + 3(y) = 106
46 + 12 + 3y =106
58 + 3y = 106
3y = 106 - 58
3y = 48
y = 48/3
y = 16
We know that Oxygen has molecular mass of 16. Therefore the element "X" is "O".

This will be classified as light on the API scale due to the large percentage of lighter fractions such as paraffins and naphthenes.
Answer:
1,085g of water
Explanation:
If we have the value 4520kj is because the question is related to Energy and heat capacity. In this case, the law and equation that we use is the following:
Q= m*C*Δt where;
Q in the heat, in this case: 4520kj
m is the mas
Δt= is the difference between final-initial temperature (change of temperature), in this exercise we don´t have temperatura change.
In order to determine the mass, I will have the same equation but finding m
m= Q/C*Δt without m=Q/C
So: m= 4,520J/4.18J/g°C
m= 1,0813 g
