<span>At room temperature and atmospheric pressure, nothing happens when the two gasses are mixed. However, at high temperature and pressure (450C, 200atm), in the presence of an iron oxide catalyst, the production of ammonia is thermodynamically advantageous.</span>
Answer:
3.91 minutes
Explanation:
Given that:
Biacetyl breakdown with a half life of 9.0 min after undergoing first-order reaction;
As we known that the half-life for first order is:

where;
k = constant
The formula can be re-written as:



Let the initial amount of butter flavor in the food be
= 100%
Also, the amount of butter flavor retained at 200°C
= 74%
The rate constant 
To determine how long can the food be heated at this temperature and retain 74% of its buttery flavor; we use the formula:


Substituting our values; we have:

t = 3.91 minutes
∵ The time needed for the food to be heated at this temperature and retain 74% of its buttery flavor is 3.91 minutes
Answer:
Look at the periodic table of elements
Explanation:
Group 1 is the most reactive and to the right
Group 18 is least reactive and all the way to the left. The rest are in between. The groups go vertical.
You'd be able to solve with this information youre welcome
<span>The gas that is formed is a different state of matter from the baking soda and lemon juice. The lemon juice has a different odor or smell than the gas. There is no color in the gas, while the lemon juice is yellow, and the baking soda is white.
