Answer:
Explanation:
Hello, there are two properties of alkaline metals that make them have that behavior:
1. They have large electrode potential which allows them to displace the hydrogen in the water.
2. They released energy when the hydrogen is displaced is big enough to make it ignite.
Now, the reaction is more violent when increasing the period of the alkaline metal because the higher the period (atomic radius as well) the higher the electrode potential which increases the released energy.
Best regards.
Answer:
Explanation:
Hello!
In this case, since the presence of silver ions is in AgNO3 only, we can compute their moles by using the volume and concentration of the corresponding salt:
Next, since the total volume of solution C is 5.00 L, the required concentration of silver ions turn out:
Best regards!
Density = Mass / Volume
Density = 2.74g / 3.10cm³
Density = 0.88 g/cm³
Answer:
150.000 g
Explanation:
The law of conservation of mass states that the mass of reactants and products of a reaction must be equal to one another.
In other words, for this case:
- Mass of KOH + Mass of HCl = Mass of Products
We are given all required data to<u> calculate the mass of the KOH solution</u>:
- Mass of KOH + 250.000 g = 400.000 g
This is because fall has more weather patterns which are repetitive than summer.
<h3>What is Weather?</h3>
This is defined as the atmospheric condition of a particular place at a given period of time.
The repetitive weather patterns have various effects on the stars which is why they were studied.
