A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets.


An iron pot is made up of only one substance, iron. Iron is an element classified as a transition metal


Iron. Elementsare pure substances that are made up of one kind of atom. Pizza is not an element because it is a mixture of many substances. Water is a pure substance, but it contains two kindsof atom: oxygen and hydrogen.

How can equilibrium of a closed system chemical reaction be disturbed? Select all that apply.
charle [14.2K]

The correct answers are :

Changing the volume of the system.

Changing the temperature of the system.

Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.

As the system is closed, we cannot add or remove products or reactants.

Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.

Also change in volume  will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.

Which one of the following metals would NOT displace hydrogen from a dilute solution of HCl? 1. Ag 2. Fe 3. Al 4. Ni
jolli1 [7]

Answer:

Ag

Explanation:

To determine which element will displace hydrogen from a dilute acid, we need to make reference to the activity series or the electrochemical series. The activity series is a list of metallic ions according to their electropositivity.

This means elements are ranked here based on how electrically positive they are. Hence, an element above another element is relatively more electropositive than the one under it. For example calcium is less electropositive compared to sodium as calcium is found under sodium in the list.

Now, for an element to displace hydrogen, it means the particular element is more electropositive than hydrogen on the activity series. All the elements in the options are in a greater position relative to hydrogen on the activity series except silver. This means it cannot displace hydrogen from a dilute mineral acid

Balancing Chemical Equations Worksheet
Goshia [24]

The balanced chemical equation of the reactions given is as follows:

  • 2LiHCO3 -----> Li2CO3 + H2O + CO2
  • 2 N2 + 5 O2 -----> 2 N2O5
  • MgBr2 + KOH -----> KBr + Mg(OH)2
  • Mn + 2 CuCl -----> 2 Cu + MnCl2
  • 8 Zn + S8 -----> 8 ZnS
  • 2 NaOH + H2SO4 -----> 2 H2O + Na2SO4
  • 2 K + 2 H2O -----> 2 KOH + H2
  • C5H12 + 8 O2 -----> 6H2O + 5 CO2
  • 2 KOH + H2CO3 -----> 2 H2O + K2CO3
  • C4H802 + 6 O2 -----> 4 H20 + 4 CO2
  • 16 Al + 3 S8 ---> 8 Al2S3

<h3>How to balance chemical equations</h3>

Balancing of chemical equations is the process of adding numerical coefficients in front of moles of reactants and products to ensure that the moles of atoms of elements of the reactants is equal to the moles of atoms of products formed.

The balanced chemical equation of the reactions given is as follows:

  • 2LiHCO3 -----> Li2CO3 + H2O + CO2
  • 2 N2 + 5 O2 -----> 2 N2O5
  • MgBr2 + KOH -----> KBr + Mg(OH)2
  • Mn + 2 CuCl -----> 2 Cu + MnCl2
  • 8 Zn + S8 -----> 8 ZnS
  • 2 NaOH + H2SO4 -----> 2 H2O + Na2SO4
  • 2 K + 2 H2O -----> 2 KOH + H2
  • C5H12 + 8 O2 -----> 6H2O + 5 CO2
  • 2 KOH + H2CO3 -----> 2 H2O + K2CO3
  • C4H802 + 6 O2 -----> 4 H20 + 4 CO2
  • 16 Al + 3 S8 ---> 8 Al2S3
