A student reacts Mg and HCl together. The product of this reaction is H, gas and MgCl2. The balanced equation for this reaction is
Mg + 2HCI - H2 + MgCl2
If I need to create 50 L of Hy, how many moles of HCI should I start with?
a) 2.3 mol HCI
b) 4.5 mol HCI
c) 1.1 mol HCI
d) 44.6 mol HCI

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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.

your answer is c) plasma
