7. Which metal is more easily oxidated, copper or aluminum?

Chemistry
1 answer:
vredina [299]2 years ago

Answer:

alumimum

Explanation:

Aluminum oxidation happens faster than that of steel, because aluminum has a really strong affinity for oxygen. Rather than flaking though, aluminum oxide just forms a hard, whitish-colored surface skin. When all the aluminum atoms have bonded with oxygen the oxidation process stops.

Under constant pressure a sample of hydrogen gas initially at 88°C and 9.6 L is cooled until its final volume is 3.4 L. What is
Scilla [17]

The final temperature = -145.24K or 127°C.

According to the data given,

T1= 88°C = 361.15K

V1= 9.6 L

V2= 3.4 L

T2= ?

We know that, according to Charles's law,

T1/V1=T2/V2

T2= T1*V2/V1

T2= 127°C or -145.24K

The final temperature = -145.24K or 127°C

<h3>What does Charles law state?</h3>

According to Charles' law, when the pressure is held constant, the volume of a given amount of gas is precisely proportional to its temperature on the kelvin scale.

<h3>What connection exists between volume and temperature?</h3>
  • In layman's words, the volume of a fixed mass of gas is exactly proportional to temperature at constant pressure.
  • When a constant mass of gas is cooled, its volume decreases, and when the temperature is elevated, its volume grows.

<h3>What are the applications of Charles law?</h3>
  • A hot air balloon drifting through the air is an illustration of Charles Law in action.
  • The air within the balloon is heated by a torch, which causes the air molecules to move more quickly and disperse.
  • This causes the air inside the balloon to be less dense than the air outside, which causes the balloon to float.

A liquid sample, with a density of .0915 g/mL has a mass of 17.7 grams.
Arlecino [84]

The relation between density, mass and volume is

Density = \frac{Mass}{Volume}

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

Density = \frac{Mass}{Volume}

Thus

Volume Volume = \frac{Mass}{Density} = \frac{17.7 g}{0.915 \frac{g}{mL} }  = 193.44 mL

Answer: 193.44 mL

2) the mass of sample will be

mass = density X volume = 0.0915\frac{g}{mL} X 76.5 mL = 6.99 = 7 g

Answer: 7 g

Ipatiy [6.2K]

Answer:

Reasonable Second step- N_{2}O(g)+H_{2}(g)\rightarrow N_{2}(g)+H_{2}O(g)

Explanation:

The given single step chemical reaction is as follows.

2H_{2}(g)+2NO \rightarrow 2H_{2}O(g)+N_{2}(g)

Suppose a two-step mechanism is proposed for this reaction,

The reaction occured in two steps they are as follows.

Step -1:H_{2}(g)+2NO \rightarrow N_{2}O(g)+H_{2}O(g)

Step-2:N_{2}O(g)+H_{2}(g)\rightarrow N_{2}(g)+H_{2}O(g)
