Answer:
b. 12 pesos
Explanation:
Given the following data;
Amount paid = 180 pesos
Amount of pad = 15 pads
To find the cost of each pad, we would use the following expression;
Substituting into the formula, we have;
Cost = 12 pesos
Therefore, the cost of each pad bought by Lorena is 12 pesos.
Answer:
0.316
Explanation:
ph --> H+ --> Oh-
H+ = 10^-ph
= 10^-12.5
= 3.16 x 10^-13
now for oh-
oh - = 1 x 10^-14 / 3.16 x 10^-13
= .0316
An oxidation number is the electrical charge a molecule or ion appears to have as determined by a set of arbitary rules.
Answer:
The new volume will be 5.80 L
Explanation:
Step 1: Data given
The initial volume = 29.0 L
The initial pressure = 562 torr = 562 /760 atm = 0.739474 atm
The pressure changes to 2810 torr = 2810 /760 atm = 3.697368 atm
The temperature and number of moles will not change
Step 2: Calculate the new volume
P1*V1 = P2*V2
⇒With P1 = the initial pressure = 0.739474 atm
⇒with V1 = the initial volume = 29.0 L
⇒with P2 = the increased pressure = 3.697368 atm
⇒with V2 = The new volume = TO BE DETERMINED
0.739474 atm * 29.0 L = 3.697368 atm * V2
V2 = 5.80 L
OR
562 torr * 29.0 L = 2810 torr * V2
V2 = 5.80 L
The new volume will be 5.80 L
