The element that has the most properties in common with Calcium (Ca) is :
Magnesium (Mg)
They both located in the same group of the table

hope this helps

atoms are made of 3 types of sub atomic particles; electrons, protons and neutrons

Of these particles, electrons are involved in the chemical reactions.

Therefore chemical properties of the element are determined by the electrons, and that too mostly the valence electrons. Valence electrons are the electrons in the outermost energy shell.

Atoms with same number of valence electrons have similar chemical properties. atoms having same number of valence electrons are classified into groups.

So elements of the same group have same number of valence electrons, hence similar chemical properties

Ca has 2 valence electrons so it belongs to group 2. Of the given elements

only Mg belongs to group 2. Therefore Mg has the most common properties with Ca

1.) Particle B has a greater kinetic energy because when a particle is at higher temperature it contains more energy.

2.) Diagram B best shows the overflow of heat between the particles. It does because of the enclosed space that it is in and how it will circulate in it.

3.) Heat is transferred between object A and B by having object B (warmer) make a reaction with object A (colder).

Reaction has a theoretical yield of 56.9 g. when the reaction is carried out, 36.6 g of the product is obtained.
musickatia [10]
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield

actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)

(56,9 x100)/36,6=
= 155%

In the reaction of chlorine with calcium, explain which atom is oxidized.
romanna [79]

Answer:

The atom is oxidized is Ca.

Explanation:

  • The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
  • The oxidation process is the process in which electrons are lost and produce positively charged ions.
  • The reduction process is the process in which electrons is gained and negatively charge ions are produced.

  • In the reaction of chlorine with calcium:

<em>Ca + Cl₂ → CaCl₂,</em>

Ca loses 2 electrons and is oxidized to Ca²⁺. (Ca <em>→</em> Ca²⁺ + 2e).

Cl is gains 2 electrons in "Cl₂, oxidation state zero" and is reduced to Cl⁻. (Cl₂ + 2e <em>→</em> 2Cl⁻).

Q1. An inorganic compound is a compound where the main constituent or substance is not that of Carbon but predominantly other elements, such as I, N etc. An organic compound is one where the main substituent or main element, the element found in much greater amounts would be Carbon.

Q2. Water is considered a very good solvent, because of its ability to dissolve well with mostly all other polar compounds, and produce ions from those ionic compounds.

A. Hydrogen atoms
B. Oxygen atom.
