Answer:
The correct answer is
moles
mole
moles
Step-by-step explanation:
In a typical stoichiometric problem, the given quantity is first converted to moles. Then the mole ratio from the balanced equation is used to calculate the moles of the wanted substance. Finally, the moles are converted to any other unit of measurement related to the unit mole.
Answer:
Before solving the given trigonometric relation change everything to sines and cosines
Step-by-step explanation:
consider the given equation;
=
Multiplying the above equation on both sides by
then we get,

By using identity,
expand above equation we will get,

Then,


So the required value of the angle is
degree.
Answer:
Centroid
Step-by-step explanation:
is it right please tell me down below thank you
You can always add or subtract
same value to/from both sides of equation. The same is true about multiplication and division.
In your case you have to subtract
x from both sides of equation in order to get rid of it on the left side:


But it's easier to remember that if you want to move some member of equation to other side, you just have to
change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):

Move
2y to the right side:

Move
8 to the left side:

Move both
x and
2y to the right side:
