Explain in complete sentences how heat is transferred in fluids.

Chemistry

In fluids, heat is often transferred by convection, in which the motion of the fluid itself carries heat from one place to another. Another way to transfer heat is by conduction, which does not involve any motion of a substance, but rather is a transfer of energy within a substance (or between substances in contact)

Look at the equation CO2 + H2 = CO + H20.
sergejj [24]

Answer:

CO is considered as a product.

Explanation:

A general chemical equation for a combination reaction follows:

To write a chemical equation, we must follow some of the rules:

The reactants must be written on the left side of the direction arrow.

A '+' sign is written between the reactants, when more than one reactants are present.

An arrow is added after all the reactants are written in the direction where reaction is taking place. Here, the reaction is taking place in forward direction.

The products must be written on the right side of the direction arrow.

A '+' sign is written between the products, when more than one products are present.

For the given chemical equation:

are the reactants in the reaction and  are the products in the reaction.

Hence, CO is considered as a product.

What mass of oxalic acid is required to prepare 250 mL of a 2.00 M solution?
melamori03 [73]

Answer:

Hope this helps!

Explanation:

The molarity of a given solution is defined as the total number of moles of solute per litre of solution.

\(Molarity = \frac{n}{V}\)

Here,

M is the molality of the solution

n is the number of moles of the solute

V is the volume of solution given in terms of litres

Molecular weight of oxalic acid (H2C2O4.2H2O) = 126 g/mol.

M = n/V

0.1 M = n/0.25L

n = 0. 025 mol

Number of moles = Given mass/Molar mass

0. 025 mol = m / 126

m = 3.15 g

So, amount of oxalic acid is 3.15 g

Describe the formation of an aqueous libr solution when solid libr dissolves in water
steposvetlana [31]

Answer and Explanation:

The water is a polar solvent which dissolves into the LiBr molecules and converts into Li^+ and Br^- ions far from the solid also into the solution, when they are hydrated.

Now, the complete words are as given below:-

The K^+ and I^- ions at the surface of the solid are pulled into the solution by the polar water molecules, where the hydration process surrounds separate ions with water molecules.
