Glycogen is formed by the loss of water molecules along the length of the polymer chain as the glucose molecules are joined together.

<h3>How is glycogen formed?</h3>

Glycogen is formed by a process known as condensation polymerization. This involves the loss of -OH from one glucose molecule and the loss of H from another glucose molecule as the chain is formed.

Hence, glycogen is formed by the loss of water molecules along the length of the polymer chain as the glucose molecules are joined together.

If you are pushing a shopping cart and you start pushing harder , what happens?

olya-2409 [2.1K]

The kinetic energy of the shopping cart increases. This speeds up the energy rate of friction between the wheel and the floor giving off more kinetic energy so the speed rate can increase (depending on how much your pushing it) Hope this helps :)

1. Which sample contains a total of 9.0 * 10 ^ 23 atoms ? A) 0.50 mole of HCI B) 0.75 mole of H 2 O C) 1.5 moles of Cu D) 1.5 mo

Alchen [17]

c. 1.5 moles of Cu will contain a total of 9.0 * 10 ^ 23 atoms.

Explanation:

To convert moles into atoms, the molar amount and number of atom is multiplied by Avagadro's number.

Avagadro's number is 6.022× $10^{23}$

So applying the formula in the given sample:

A) 0.5×6.022× $10^{23}$

3.01× $10^{23}$ atoms.

B) 0.75 mole of H20

O.75×6.022× $10^{23}$

= 4.5166× $10^{23}$ atoms.

C) 1.5 moles of Cu

1.5×6.022× $10^{23}$

= 9.033× $10^{23}$

D). 1.5 moles of H2

1.5 × 2 × 6.022 × $10^{23}$

= 18.066 × $10^{23}$ atoms because H2 is 2 moles of hydrogen.

Atom is the smallest entity of matter having property of the element to which it is a part.

Which equation represents the correct net ionic equation for the reaction between Ca(OH)2 and H2SO4?

Georgia [21]

<u>Answer:</u> The correct net ionic equation for the reaction is $2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$

<u>Explanation:</u>

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.

The balanced molecular equation is:

$Ca(OH)_2(aq)+H_2SO_4(aq)\rightarrow CaSO_4(aq)+2H_2O(l)$

The complete ionic equation follows:

$Ca^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2Ca^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)$

As calcium and sulfate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

$2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$

Hence, the correct net ionic equation for the reaction is $2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)$
