Answer: b. 12.9 grams
Explanation:
According to avogadro's law, 1 mole of every gas occupies 22.4 Liters at STP ,contains avogadro's number of particles and weighs equal to the molecular mass.
Thus at STP :
1 mole of hydrogen is produced by 2 moles of sodium metal
i.e. 22.4 L of is produced by 46 gram of sodium metal
6.3 L of is produced by=
of sodium metal
The equation : y=3x-5
<h3>Further explanation </h3>Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates
General formula
y-y1 = m(x-x1)
or
y = mx + c
Where
m = straight-line gradient which is the slope of the line
x1, y1 = the Cartesian coordinate that is crossed by the line
c = constant
The formula for a gradient (m) between 2 points in a line
m = Δy / Δx
Answer: picture is work for # 1,2,4,5,7
Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.
number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.
hope this helps :))
