Answer:

25 g/hr

Explanation:

Remember that the rate of reaction refers to the rate at which reactants are used up or or the rate at which products appear.

Hence;

Rate of reaction = mass of reactant used up/time taken

Mass of reactant used up= 2g

Time taken = 5 minutes or 0.08 hours

Rate of reaction = 2g/0.08 hours = 25 g/hr

Can metals have covalent radius and van der Waal's radius instead of metallic radius?​
romanna [79]

Explanation:

Whether you choose to use van der Waals radii or metallic radii as a measure of the atomic radius, for metals the ionic radius is smaller than either, so the problem doesn't exist to the same extent. It is true that the ionic radius of a metal is less than its atomic radius (however vague you are about defining this).

How many moles is 34.4 g of Oxygen gas (O2)?
jasenka [17]

Answer:

n = 1.075  moles

Explanation:

Given that,

Mass of oxygen = 34.4 gram

The molar mass of oxygen gas = 32 g/mol

We need to find the number of moles of oxygen. We know that,

No. of moles = given mass/molar mass

So,

n=\dfrac{34.4\ g}{32\ g/mol}\\\\=1.075\ mol

So, there are 1.075  moles in 34.4 g of Oxygen gas.

Answer:

salt in the Dead Sea is sodium chloride

while salt in the lab is either soluble or

insoluble in water.

Explanation:

The term 'salt' in the school laboratory does not always refer to sodium chloride. It is a generic term used for many substances especially those substances formed by neutralization reaction.

There are many salts that are used in the laboratory. Some of these salts are soluble in water while some are not soluble in water.

Salt in the dead sea always refers to sodium chloride, hence, salt in the dead sea is different from salt in the school laboratory.
