Answer:
![B](https://tex.z-dn.net/?f=B)
Explanation:
Here, we want to check if the equation of the reaction is balanced or not
Now, for a balanced equation of reaction, the number of atoms of the individual elements on both sides of the equation is equal
Now, let us check the atoms:
We have 1 Sr on both sides
We have 1 SO4 on both sides
We have 1 Mg on both sides
We have 2 OH on both sides
From what we can see, the equation of the reaction is balanced
Thus, the correct answer choice is B
Answer:
gases
Explanation:
The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Answer:
260.34g
Explanation:
First, you need to know what angelic acid is comprised of. It is written as C₅H₈O₂.
In order to solve for the mass of 2.6 moles of angelic acid, you need the mass of 1 mole of angelic acid. This can be found by adding the masses from the periodic table, like shown below:
5 carbon atoms = (5)(12.01g) = 60.05g
8 hydrogen atoms = (8)(1.01) = 8.08g
2 oxygen atoms = (2)(16) = 32g
angelic acid = 60.05 + 8.08 + 32 = 100.13g
Then, set up a basic stoichiometric equation and solve. The units should cancel out.
![(\frac{2.6mol}{1} )(\frac{100.13g}{1mol} )=260.34g](https://tex.z-dn.net/?f=%28%5Cfrac%7B2.6mol%7D%7B1%7D%20%29%28%5Cfrac%7B100.13g%7D%7B1mol%7D%20%29%3D260.34g)
Elements are the same type of atoms, so there is nothing else to separate. Hydrogen has hydrogen atoms, and no other kind. Therefore nothing can be taken out of it anymore. Chemical x is a mixture, made by y and z. Nothing can make up y and z but themselves.
