Answer:
94.58 g of 
Explanation:
For this question we have to start with the reaction:

Now, we can balance the reaction:

We have the amount of
and the amount of
. Therefore we have to find the limiting reactive, for this, we have to follow a few steps.
1) Find the moles of each reactive, using the molar mass of each compound (
).
2) Divide by the coefficient of each compound in the balanced reaction ("2" for
and "1" for
).
<u>Find the moles of each reactive</u>


<u>Divide by the coefficient</u>
<u />


The smallest values are for
, so hydrogen is the limiting reagent. Now, we can do the calculation for the amount of water:

We have to remember that the molar ratio between
and
is 2:2 and the molar mass of
is 18 g/mol.
Answer:
of acetic anhydride is needed
Explanation:
According to balanced equation, 1 mol of salicylic acid completely reacts with 1 mol of acetic anhydride
Number of moles = (mass)/(molar mass)
Molar mass of acetic anhydride = 102.09 g/mol
Molar mass of salicylic acid = 138.121 g/mol
So,
of salicylic acid =
of salicylic acid
Hence,
of salicylic acid reacts completely with
of acetic anhydride.
So, mass of acetic anhydride needed =
= 
Mass was conserved, because it was losing all shape, weight, and matter. It really has no mass.
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Answer:
Explanation-
Water is a compound because it is formed from hydrogen and oxygen, which is irreversible, having different properties but air is a combination of different gases in any proportion.
