During an investigation a scientist heated 2.76 g of silver carbonate till it decomposed to leave a silver residue. The total ma

ss of the silver residue formed was 2.16 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations.

The equation that shows the decomposition of silver carbonate is as follows:
2Ag2CO3 > 4Ag + 2CO2 + O2--------------------------------------------------------------------------------------------------okay, now from the periodic table:mass of silver is 107.8682 gramsmass of carbon is 12 gramsmass of oxygen is 16 gramsmolar mass of Ag2CO3 is 2(107.8682) + 12 + 3(16) = 275.7364 grams------------------------------------------------------------------------------------------------From the balanced equation above:2(275.7362) = 551.4728 grams of Ag2CO3 produces 4(107.8682) = 431.4728 grams of Ag------------------------------------------------------------------------------------------------------Therefore, to know the mass of Ag produced from 2.76 grams of Ag2CO3, we will simply use cross multiplication as follows:mass of Ag produced = (2.76*431.4728) / (551.4728) = 2.16 grams==========================================================
Based on the above calculations, the law of conservation of mass is applied.

The tires on your truck have 0.35 m radius. In a straight line, you drive 2600 m. What is the angular displacement of the tire,
Travka [436]
1) In a circular motion, the angular displacement \theta is given by
\theta =  \frac{S}{r}
where S is the arc length and r is the radius. The problem says that the truck drove for 2600 m, so this corresponds to the total arc length covered by the tire: S=2600 m. Using the information about the radius, r=0.35 m, we find the total angular displacement:
\theta =  \frac{2600 m}{0.35 m} =7428 rad

2) If we put larger tires, with radius r=0.60 m, the angular displacement will be smaller. We can see this by using the same formula. In fact, this time we have:
\theta =  \frac{2600 m}{0.60 m}=4333 rad

The first law of thermodynamics relates the heat transfer into or out of a system to the change of internal and the work done on
Artyom0805 [142]

Answer:

The heat transferred into the system is 183.5 J.

Explanation:

The first law of thermodynamics relates the heat transfer into or out of a system to the change of internal and the work done on the system, through the following equations.

ΔU = Q - W

where;

ΔU  is the change in internal energy

Q is the heat transfer into the system

W is the work done by the system

Given;

ΔU = 155 J

W = 28.5 J

Q = ?

155 = Q - 28.5

Q = 155 + 28.5

Q = 183.5 J

Therefore, the heat transferred into the system is 183.5 J.
