Does acid rain make new substances?

ivanzaharov [21]

Answer:

Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air.

Heat is added to a 200.-gram sample of H2O(s) to melt the sample at 0°C. Then the resulting H2O (image) is heated to a final tem

pochemuha

You are given 200 grams of H2O(s) at an initial temperature of 0°C. you are also given the final temperature of water after heating at 65°C. You are required to get the total amount of heat to melt the sample. The specific heat capacity, cp, of water is 4.186 J/g-°C. Let us say that T1 = 0°C and T2 = 65°C. The equation for heat, Q, is

Q = m(cp)(T2-T1)
Q = 200g(4.186 J/g-°C )(65°C - 0°C)
<u>Q = 54,418J</u>

A gas occupies 900.0 mL at a temperature of 27.0 ˚C. Assuming constant pressure, what is its volume if it is heated to 132.0 ˚C?

Stella [2.4K]

Answer:

new volume is 1215mL

Explanation:

using Charles law , the volume of a fixed mass of gas is directly proportional to its temperature provide that pressure is kept constant.

$\frac{V1}{T1}=\frac{V2}{T2}$

V1=900mL ,

convert the temperatures from Celsius to kelvin temperature.

T1 =27°C =27+273 =300K

T2 =132°C = 132+273=405K

$V2=\frac{V1T2}{T1}$

$V2=\frac{900*405}{300}$

V2= 1215mL

(40 Points) Complete, balance, compute the amounts of the products assuming 100% yield. 12g Zinc Solid + 24g Silver Nitrate

VARVARA [1.3K]

Answer:

Zn + 2AgNO₃ → Zn(NO₃)₂ +2Ag

13.34g Zn(NO₃)₃ and 15.24g Ag are formed if reaction is 100% complete.

Explanation:

molar mass of Zn=65 g

molar mass of AgNO₃=170 g

molar mass of Zn(NO₃)₂ =189 g

molar mass of Silver = 108 g

Zn + 2 AgNO₃ → Zn(NO₃)₂ +2 Ag eq(1)

1 mole Zn reacts with 2 moles Silver nitrate to give 1 mole Zinc nitrate and 2 moles Silver

65 g Zn reacts with 2×170 g of AgNO₃ → 189 g Zn(NO₃)₂ and 2×108 g Ag - eq(2)

First find limiting reagent of the reaction

65g Zn reacts with 2×170g of AgNO₃

12 g Zn reacts with (12÷65)×2×170 g AgNO₃

=62.7 g AgNO₃

For the reaction to go to 100% yield 12 g Zn will need 62.7 g AgNO₃

but amount of AgNO₃ is 24 g

So the reaction yields is limited by amount of AgNO₃.

AgNO₃ is the limiting reagent.

So calculate the yield of products with the amount of AgNO₃

by eq(2)

2× 170 gAgNO₃ gives 189 g Zn(NO₃)₃

=340 g AgNO₃ gives 189 g Zn(NO₃)₃

24 g AgNO₃ gives (24÷340) ×189 g Zn(NO₃)₃

=13.34g Zn(NO₃)₃

again by eq2

2×170 g AgNO₃ gives 2×108 g Ag

= 340 g AgNO₃ gives 216 g Ag

24 g AgNO₃ gives (24÷340)×216 g Ag

= 15.24g Ag
