Answer:
v₂ = 39L
Explanation:
Given parameters:
Initial volume of gas = 20L
Initial temperature = 140K
Unknown:
Final volume = ?
Solution:
Since the standard temperature of any gas is 273K, the final temperature is this 273K;
Applying Charles's law:
= 
v and T are volume and Temperature
= 
v₂ x 140 = 20 x 273
v₂ = 39L
Answer:
Bromine (Br)
Explanation:
Im assuming thats the answer you are looking for since you didnt include any options :,)
Answer:
The equation showing the dissolving of solid ammonium phosphate in water is: (NH4)3 PO4 (s) → 3NH4 +1 (aq) + PO4 -3 (aq).
Explanation:
This question is incomplete, the complete question;
A reaction between liquid reactants takes place at 16°C in a sealed, evacuated vessel with a measured volume of 10.0 L . Measurements show that the reaction produced 37.g of dinitrogen monoxide gas.
Calculate the pressure of dinitrogen monoxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits.
Answer:
Explanation:
Given that;
Volume = 10.0 L
Temperature T = 16°C = ( 16 + 273) = 289 K
we know that molar mass of N₂O = 44 g/mol
number number of moles n will be: weight/molar mass = 37/44 = 0.8409 moles
Universal Gas constant R = 0.0821 atm.mol⁻¹.k⁻¹
pressure p = ?
from the ideal gas law
PV = nRT
P = nRT / n
so we substitute
P = (0.8409 mole × 0.0821 atm.mol⁻¹.k⁻¹ × 289 K) / 10.0 l
P = 19.95195 / 10.0
P = 1.9952 atm
Products and reactants are substances. The first one (the products) are obtained when the reactants are changed. The process of change of one element into another is called chemical reaction. The reactants are transformed during the chemical reaction into products. Limiting reactant is the reactant which defines the amount of product as a a result of the reaction. This reactant is also called limiting reagent.
