PLEASE HELP

Chemistry
1 answer:
Anna71 [15]3 years ago
6 0

Answer:

Explanation:

Balanced equation

2Fe + 3H2SO4 → Fe2(SO4)3 + 3H2.

Subscripts

This is a very important question. It is good to know the answer. The subscripts cannot be altered because that's the way the molecule is constructed. For example, it takes 2 Hydrogens to mix with one SO4 ion. That's the way Sulfuric acid is found in nature. There are no other ways to write 2H+ and SO4-2

You can alter (and you must alter) the way the molecules react with each other. You need to make sure that the Conservation of Mass law is always being obeyed. So when you have 6 H's on the left, you must have the same number on the right. 6 grams of hydrogen on the left = 5 hydrogens on the right.

What characteristics do the elements in a group share? In a period, share?
Katyanochek1 [597]

Answer:

The elements in same period have same principle quantum number or energy shell.

The elements in same group shows similar chemical and properties.

Explanation:

Inn group:

The elements in same group i.e present in vertical column shows similar chemical properties.

The elements in same group having same number of valance electrons. while in chemical reaction bonds are break and formed and valance electrons are involved. That's why elements in same group having same number of valance electrons and shows similar chemical properties.

In period:

While as we move from left to right the number of valance electron increase by one in every element. But the electron is added in same shell which means that their physical and chemical properties are different but principal quantum number is same.

Which of the following equations of CH4 + Cl2
mylen [45]

Balanced equation : C. CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

<h3>Further explanation  </h3>

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

CH₄ + Cl₂⇒  CCl₄+ HCl

  • Give coefficient :

aCH₄ + bCl₂⇒  CCl₄+ cHCl

  • Make equation :

C, left=a, right=1⇒a=1

H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4

Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4

The equation becomes :

CH₄ + 4Cl₂⇒  CCl₄+ 4HCl
