Answer:
1.02KPa
Explanation:
The following were obtained from the question:
V1 = 1550mL
P1 = 70.26kPa
T1 = 480°C = 480 + 273 = 753K
T2 = -237°C = - 237 + 273 = 36K
V2 = 5114mL
P2 =?
The final pressure can obtain as follows:
P1V1/T1 = P2V2/T2
(70.26x1550)/753 = (P2x5114)/36
Cross multiply to express in linear form as shown below:
P2 x 5114 x 753 = 70.26 x 1550 x 36
Divide both side by 5114 x 753
P2 = (70.26x1550x36)/(5114x753)
P2 = 1.02KPa
Therefore, the final pressure is 1.02KPa
Because H2O molecules make Hydrogen bounding and that's the first and strongest bound between molecules of a structure... So they stick together and don't let each other get evaporated...
U need lotsa energy to turn them into Gas shape
Answer:
305 litres of NO gas will be produced from 916 L of NO₂
Explanation:
Given the balanced equation of the chemical reaction as follows:
3 NO₂ (g) + H₂O( l) —— 2 HNO₃ (l) + NO (g)
Under standard conditions, 3 moles of No₂ will react with 1 mole of water to produce 1 mole of NO gas.
Molar volume of a gas at STP is 22.4 L
Number of moles of NO₂ gas present in 916 L = 916/22.4 = 40.893 moles of NO₂ gas
From the mole ratio of NO₂ to NO in the equation of reaction,
Number of moles of NO that will be produced = 1/3 × 40.893 moles = 13.631 moles of NO gas
Volume of 13.631 moles of NO gas = 13.631 × 22.4
Volume of NO gas produced = 305.334L
Therefore, Volume of NO gas produced from the reaction of 916 L of NO₂ with water = 305 L
Answer: C₂H₄+3 O₂= 2 CO₂+ 2 H₂O
Explanation:
Answer:
3 (NH4)2SO4(aq) + 2 Al(NO3)3(aq) → 6 NH4NO3(aq) + Al2(SO4)3(aq)
Explanation:
In solubility rules, all ammonium and nitrates ions are solubles and all sulfates are soluble except the sulfates that are produced with Ca²⁺, Sr²⁺, Ba²⁺, Ag⁺ and Pb²⁺. That means the NH4NO3 and the Al2(SO4)3 produced are both <em>soluble and no precipitate is predicted. </em>
The reaction is:
<h3>3 (NH4)2SO4(aq) + 2 Al(NO3)3(aq) → 6 NH4NO3(aq) + Al2(SO4)3(aq)</h3>
