Answer : The correct match is:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges

Explanation :

As we now that there are three subatomic particles which are protons, electrons and neutrons.

The protons and neutrons are located inside the nucleus and electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and neutrons are neutral.

As we know that all the things are made up of charges and opposite charges attract to each other.

In a neutral atom, the positive charges and negative charges are balanced in an object. That means, in neutral atom the number of positive charges are equal to the negative charges.

So we can say that:

1 positive charge = 1 negative charge

2 positive charges = 2 negative charges

3 positive charges = 3 negative charges

What component of amino acid structure varies among different amino acids?
givi [52]

Answer

The components of the r group of amino acid structure varies among different amino acids

Explanation  

As the functional group for amino acids is as:  

R-CH-COOH  

 I  

NH2  

only R differs so amino acids also differs. If R is “H” then amino acid is glycine and if R is “CH3” then amino acid is alanine. Hence, R is different for different amino acids. Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.

If 6 mol of H, react, how many moles of ammonia will be produced?
PtichkaEL [24]

Moles of Ammonia produced : 4 moles

<h3>Further explanation</h3>

Given

6 mol of H₂

Required

moles of Ammonia

Solution

Reaction

N₂ + 3H₂ → 2NH₃

In chemical equations, the reaction coefficient shows the mole ratio of the reacting compound (reactants and products)

From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so mol NH₃ :

= 2/3 x moles H₂

= 2/3 x 6

= 4 moles
