Answer:
The answer to your question is number 2. NaNO₃ + H₂O
Explanation:
The reaction that is represented in this problem is an acid-base reaction. An acid-base reaction is a double displacement reaction.
The cation of a reactant attaches to the anion of the other reactant and viceversa.
Reactants NaOH and HNO₃
Cations Na⁺ H⁺
Anions OH⁻ NO₃⁻
Following the previous rule
Products NaNO₃ + H₂O
The products are a salt and water.
Answer:
Warmer air can hold more water vapor than colder air.
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object (body).
On the other hand, humidity refers to the concentration (amount) of water vapor that is present in the air. It is high when there's a lot of water vapor in the air and low when the level of water vapor is small.
The relationship between air temperature and humidity is that warmer air can hold more water vapor than colder air because as the air cools, its molecules move closer together while the molecules move farther apart as the air become hot.
Additionally, at constant humidity, relative humidity is inversely proportional to temperature i.e as the temperature decreases, relative humidity increases.
a. Group 2
b. Metal
a. The current highest numbered element known is Oganesson with an atomic number of 118 and it's the last period 7 element in group 18 (Noble gases). The hypothetical element number 120, would be the 2nd element in period 8 and the described electron configuration matches other group 2 elements such as Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
b. The hypothetical element would be quite similar to the other group 2 elements which are the alkaline earth metals. The element would be expected to be a bit more reactive than Radium.
Answer:
B. (Linear graph with positive slope)
Explanation:
The picture above showing that
1. T2 is higher than T1
2. V2 is higher than V2
From this, we can conclude that the relationship for temperature (T) and volume(V) is positive. That means a higher temperature will result in a higher volume.
Since the relationship positive, the graph will have a positive slope. We can't prove if the graph should be linear or exponential since we don't have the exact number of the experiment.
