It describes how, when particles/mc/elements react, despite forming different substances the mass is neither created nor destroyed but only converted.
We can solve this problem using the formula:
P2 – P1 = ρ g (h2 – h1)
where,
P2 = pressure of the gas manifold = ?
P1 = pressure of the outside air = 754 torr = 100,525 Pa
ρ = density of mercury = 13560 kg/m^3
h2 = height in gas manifold = 76.2 cm = 0.762 m
h1 = height in air = 23.8 cm = 0.238 m
So w can directly find for P2:
P2 = 13560 * 9.81 * (0.762 – 0.238) + 100,525
P2 = 170,229.37 Pa
Convert back to torr:
<span>P2 = 170,229.37 Pa = 1276.83 torr (ANSWER)</span>
We have to look for safe and non - hazardous characterstics when trying to find new propellants.
<h3>What are propellants ?</h3>
Propellants are any gas, liquid, or solid the expansion of which can be used to impart motion to another substance or object.
The Desirable properties for propellant combinations are ;
- low molecular mass and high temperature of reaction products (for high exhaust velocity),
- high density (to minimize tank weight),
- low hazard factor (e.g., corrosivity and toxicity),
- low environmental impact,
- low cost.

#SPJ1
<h3><u>Answer;</u></h3>
= 459 g of Aspartame
<h3><u>Explanation;</u></h3>
1 mole of aspartame = 294.3 g
But;
Moles = mass/molar mass
Therefore;
Mass = moles × molar mass
= 1.56 moles × 294.3 g/mol
= 459 g of Aspartame
There are 20n nutrons in the atom k-42.
