Given the points
r(-4,-1) r' (8,5)
s (-6,3) s' (6,9)
which of the following transformations maps rs to r's'?
a.
translate horizontally 12 units and vertically -6 units
b.
translate horizontally -12 units and vertically 6 units
c.
translate horizontally -12 units and vertically -6 units
d.
translate horizontally 12 units and vertically 6 units

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

gas and precipitate r the correct answers

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
