1. element
2. compound
3. element
4. compound
5. compound
6. compound

basically, if its on the periodic table, its an element. for example, rock can be made of many things in the periodic table, therefore its a compound. salt, is NaCl, which are two elements put together, therefore its a compound.

How much heat is required to change temperature of 2g of water from 34°C to 68°C? (Water has a specific heat of 4.18)

statuscvo [17]

Answer: B

Explanation:

To find the amount of heat required, you would use q=mcΔT.

$q=2g(4.18J/g°C)(68-34°C)$

q=284.2 J

*Please ignore the capital A in the equation. I can't find a way to type in the degree sign into the equation without the A appearing.

A chemist is studying the following reaction: NO + NO2 ⇌ N2O3. She places a mixture of NO and NO2 in a sealed container and meas

Answer:

The reaction will continue in the forward direction until all the NO or all the NO₂ is used up.

Explanation:

Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

So, according to Le Chatelier's principle, removing the product (N₂O₃) from the system means decreasing the concentration of the products; thus, the reaction will proceed forward to produce more product to minimize the stress of removing N₂O₃ from the system.
