<u>Answer:</u> The element having similar chemical properties that of calcium present in period 3 is magnesium.

<u>Explanation:</u>

In a periodic table, elements are arranged in 18 vertical columns known as groups and 7 horizontal rows known as periods.

Elements arranged in a group show similar chemical properties because of the presence of same number of valence electrons.

We are given:

Calcium is the 20th element of the periodic table having electronic configuration $1s^22s^22p^63s^23p^64s^2$

It has 2 valence electrons.

The element present in period 3 and have the same number of valence electron or in the same group is magnesium.

Hence, the element having similar chemical properties that of calcium present in period 3 is magnesium.

The yeast acted as a catalyst. Explain the purpose of a catalyst in a reaction

Anna71 [15]

Answer:

The catalyst speeds up the chemical reaction.

Explanation:

The process in which chemical reaction rate increases by addition of substance is termed as a catalyst. The chemical reaction happens faster when a catalyst is present because it gives an alternative reaction pathway with lower activation energy.

The catalyst usually forms a temporary intermediate that helps in regenerating the original catalyst in the cyclic process. Yeast when added in a mixture work as a catalyst and helps with chemical reaction.

Some compounds are described as binary compounds what does this mean

zubka84 [21]

Answer:

It means these compounds are only made up of two elements.

Explanation:

Binary compounds:

The compounds which are made up of the atoms of only two elements are called binary compounds.

For example:

The following compounds are binary:

HCl

H₂O

NH₃

HCl is binary because it is composed of only hydrogen and chlorine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.

water is also binary because it is also made up of only two elements hydrogen and oxygen.

While all polyatomic compounds are not binary. for example,

H₂SO₄

It is made up of hydrogen, sulfur and oxygen. There are three elements are present in this compound. So, it is not binary compound.
