Anhydrous salts absorb moisture from their surroundings when it gets cooled, hence the mass of the content would increase. It can be prevented if we allow the evaporating dish to cool in a dessicator. A dessicator is a glass or plastic container in which chemicals can be stored and allowed to cool. This container can be sealed. Dessicator would provide an environment free of moisture instead of keeping in atmospheric air having moisture content.

Answer:</h3>
2CO(g) + O₂(g) → 2CO₂(g)

Explanation:</h3>
What is a balanced chemical equation?
- A balanced chemical equation is one that has equal number of atoms of each element involved in the reaction on both side of the equation.
How do we balance chemical equations?
- Balancing chemical equations is a try and error process that involves putting appropriate coefficients on the reactants and products in a chemical reaction.
Why is it important to balance chemical equation?
- Chemical equations are balanced so as to obey the law of conservation of mass.
In this case; the balanced chemical equation for the reaction between carbon monoxide and oxygen gas is given by;
2CO(g) + O₂(g) → 2CO₂(g)
- This is because there are 2 carbon atoms and 4 oxygen atoms on both the reactant and product side.
Maybe nobody ever mentioned it to you, but it turns out that
current is another one of those things that's always conserved ...
it can't created or destroyed, just like energy and mass.
The total current in a circuit is always the same, but it can get
split up and travel through different paths for a while.
<span>==> The total current is just the amount of current
that's flowing in and out of </span><span>the battery.
Diagram #1).
</span>The total current coming out of the battery is 15 A.
That current is going to split up when it reaches the resistors.
Part of it will flow through each resistor, but both of them
will still add up to 15 A .
You have 9 A flowing through one resistor.
So the current in the other resistor is (15 - 9) =<span> 6 A.
Diagram #2).
</span>The total current coming out of the battery is 10 A.
That current is going to split up when it reaches the resistors.
Part of it will flow through each resistor, but all of them
will still add up to 10 A .
You have 2.5 A through one resistor and 3.5 A through another one.
So the amount left for the last resistor is (10 - 2.5 - 3.5) =<span> 4 A.</span>
The density is about 3.88. You just have to divide the mass and the volume. You can check this on a calculator, too. Hope this helped
