Answer:
The answer to your question is: letter D.
Explanation:
Double replacement reaction is when the cation of one reactant replaces the metal of the other reactant and vice versa.
a. 2SO2 + O2 —> 2S03 This is a combination reaction
b. Zn + Cu(NO3)2 → Zn(NO3)2 + Cu This is a single replacement reaction.
c. 2H2O2–> 2H2O + O2 This is a decomposition reaction
d . AgNO3 + NaCl → AgCl + NaNO3 This is a double replacement reaction
Answer:
V₂ = 1518L
Explanation:
-Using combined gas law:

<em>Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
<em>Initial states:</em>
P₁ = 743 torr
V₁ = 975L
T₁ = 30°C + 273.15K = 303.15K
P₂ = 375 mmHg = torr
V₂ = Our incognite
T₂ = -35°C + 273.15K = 238.15K
Replacing:

<h3>V₂ = 1518L</h3>
Answer:
a
Explanation:
Its renewable because of the reproduction and the are born every spring
Answer : The partial pressure of
is 102.3 mmHg.
Explanation :
As per question,
Mass of
= 62.9 g
Mass of
= 33.2 g
Molar mass of
= 18 g/mole
Molar mass of
= 62 g/mole
First we have to calculate the moles of
and
.


Now we have to calculate the mole fraction of
and
.


Now we have to partial pressure of
.
According to the Raoult's law,

where,
= partial pressure of water vapor
= total pressure of gas
= mole fraction of water vapor


Therefore, the partial pressure of
is 102.3 mmHg.
