The maximum numbers of electrons possible for the first four energy levels are shown in the Figure above. For example, energy level I can hold a maximum of two electrons, and energy level II can hold a maximum of eight electrons. The maximum number depends on the number of orbitals at a given energy level.

Chemical equation:

Cd + H₂SO₄    →    CdSO₄ + H₂

In given reaction Cd replace the hydrogen and form cadmium sulfate and hydrogen gas.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Other options are incorrect because,

Combustion:

In combustion reaction substances are burn in the presence of oxygen and form carbon dioxide and water.

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

A + B  →  AB

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

Constance has an apple that weighs 85,000 milligrams and a peach that weighs 0.15 kilograms. which fruit has the greater mass? c
Rama09 [41]

The fruit which has the greater mass is peach i.e. 150 grams.

<h3>What is mass?</h3>

Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.

We have given,

Weight of apples = 85,000 mg

Weight of peach = 0.15 kg

To compare the quantity first we have to convert both of these units in the same unit, and we know that:

In 1 kilogram = 1000 grams

And in 1 grams = 1000 milligrams

So, we convert both the units into grams as:

85,000 mg =  85,000 / 1000 = 85 grams

0.15 kg = 150 grams

So, the mass of peach is high.

Hence, peach has the greater mass.
