Glucose, one type of monosaccharide, is represented by the chemical formula, c6h12o6. if you were to put together 2 glucose mole

cules, why wouldn't the molecular formula for the newly made disaccharide be c12h24o12

Answer:

This is because of the removal of water molecule during condensation reaction between two glucose molecules.

Explanation:

The molecule of glucose has molecular formula ofC_6H_{12}O_6.

When two molecules of monosaccharide adds up together they form disaccharide molecule of carbohydrate. During the addition of two monosaccharides condensation reaction occurs in which removal of small molecule like water takes place.

C_6H_{12}O_6+C_6H_{12}O_6\rightarrow C_{12}H_{22}O_{11}+H_2O

To combine these you would need to perform Dehydration synthesis which removes a water molecule. So it would be c12h22o11

Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water. Suppose 2.1 grams of ethane i
swat32

Answer:

= 3.78 g H₂O

Explanation:

2C₂H₆ + 3O₂ => 4CO₂ + 6H₂O

2.1g C₂H₆ = 2.1g/30.0 g/mol = 0.07 mole ethane

3.68g O₂ = 3.68g/32 g/mol = 0.115 mole oxygen

Limiting Reactant:

A quick way to determine limiting reactant is to divide moles of reactant by its respective coefficient in the balanced molecular equation. The smaller value is the limiting reactant.

moles ethane = 0.07 mole / 2 (the coefficient in balanced equation) = 0.035

moles oxygen = 0.115 mole / 3 (the coefficient in balanced equation) = 0.038

Since the smaller value is associated with ethane, then ethane is the limiting reactant and the problem is worked from the 0.07 moles of ethane in an excess of O₂.

From the equation stoichiometry ...

2 moles C₂H₆  in an excess of O₂ => 6 moles H₂O

then 0.07 mole C₂H₆  in an excess of O₂ => 6/2(0.07 moles H₂O = 0.21 mole

Converting to grams of water produced

= 0.21 mole H₂O X 18 g/mol = 3.78 g H₂O

The removal of one or more electrons from a neutral atom results in and
Studentka2010 [4]

Answer:

The removal of one or more electrons from a neutral atom results in a cation.

Explanation:

When you remove electrons from a neutral atom, the atom becomes more positive. Electrons have a negative charge and the protons inside of the nucleus have a positive charge. When electrons are removed, the positive charges from the protons outweigh the negative charges. This results in a positively charged atom, called a cation.

Aqueous potassium bromide reacts with aqueous silver nitrate AgNO3 to form aqueous potassium nitrate KNO3 and solid silver bromi
ddd [48]
The balanced chemical equation for the reaction  is as below

 KBr (aq) + AgNo3  → KNO3(aq)  + AgBr(s)

  Explanation

    from the equation above  the  stoichiometric  coefficient  before KBr is 1,  before  AgNo3  is 1 ,  before KNO3  is 1  and before AgBr is also 1.  Therefore   1 mole of KBr  reacted with  1 mole of AgNO3  to form 1 mole of KNO3  and 1 mole  of AgBr.
