___________ is the scale used to describe how acidic or basic a solution is. This affects the enzymes within living systems.
nydimaria [60]

Answer:

pH scale

Explanation:

pH scale -

In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .

The scale has reading ranging from 1 to 14 ,

where ,

  • If the pH value less than 7 indicates the solution to be acidic in nature ,
  • If the pH value is exactly equal to 7 , the solution is neutral in nature ,

and ,

  • If the pH value more than 7 indicates the solution to be basic in nature ,

Hence , from the given statement of the question ,

The correct answer is pH scale .

How many moles of water are in 24.3 grams of water?
shtirl [24]

Answer:

Explanation: n=m/M(molar mass)

n=24.3 grams/(16+2x1.008)grams/moles(molar mass of H2O)

n=24.3grams/18.016grams/moles

n=1.35moles

If 8.6 g of ch4 and 5.9 g of o2 react, what is the mass, in grams, of h2o that is produced?
Alenkasestr [34]
This may seem confusing because they give you two masses, but all you have to do is pick one to do the calculations. Personally, I would pick O2, since the molar mass is easier to calculate. The answer would be 3.3 g (rounded for sig figs). To get this, first take the 5.9 grams of O2 and convert it to moles by dividing by the molar mass of oxygen gas, which is 32. Then, multiply both by the mole-mole ratio, which is 2:2, or simply 1:1. After that, multiply that by 18g, which is the molar mass of water to get grams of water. 

REMEMBER, you have to write and balance the chemical equation before you can do any of that work. 
That happens to be CH4 + 2O2 => CO2 + 2H2O
