Answer:
4.0 x 10^-10
Explanation:
First, you want to get the pH.
Subtract by 14.
14-4.60=9.40
Use the pH equation to find [H+].
Remember that the conversion goes like this: [H+]= 10^-pH
= 10^-9.40
=3.98 x 10^-10
=4.0 x 10^-10
Hoped this helped.
Answer:
528.25 Calories
Explanation:
From the question given above, the following data were obtained:
Energy in Joules = 2210.20 J
Energy in calories =?
We can convert 2210.20 J to calories by doing the following:
4.184 J = 1 cal
Therefore,
2210.20 J = 2210.20 J × 1 cal / 4.184 J
2210.20 J = 528.25 Calories
Thus, 2210.20 J is equivalent to 528.25 Calories.
Answer:
the normality of the given solution is 0.0755 N
Explanation:
The computation of the normality of the given solution is shown below:
Here we have to realize the two sodiums ions per carbonate ion i.e.
N = 0.321g Na_2CO_3 × (1mol ÷ 105.99g)×(2eq ÷ 1mol)
= 0.1886eq ÷ 0.2500L
= 0.0755 N
Hence, the normality of the given solution is 0.0755 N
If in the following diagram the substance is in the solid state during stage 1, during stage 2 the substance is boiling or condensing .
Boiling<span> is the term used to describe the rapid vaporization of a liquid. Boiling occurs when a liquid is heated to its </span>boiling<span> point.
</span>Condensation happens when the gas is changed into liquid.
I'd recommend checking out some videos on youtube to get some good examples worked out, for example, the video "<span>How to Balance Chemical Equations in 5 Easy Steps: Balancing Equations Tutorial" is done well.</span>
