Balance the following equations by inserting the proper coefficients. agno3+cacl2ca(no3)+agcl

2AgNO₃ + CaCl₂ ⟶ 2AgCl + Ca(NO₃)₂

Explanation:

Put a 1 in front of the most complicated-looking formula [Ca(NO₃)₂)]:

AgNO₃ + CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance Ca:

Put a 1 in front of CaCl₂.

AgNO₃ + 1CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance N:

Put a 2 in front of AgNO₃.

2AgNO₃ + 1CaCl₂ ⟶ AgCl + 1Ca(NO₃)₂

Balance O.

Done.

Balance Ag.

Put a 2 in front of AgCl.

2AgNO₃ + 1CaCl₂ ⟶ 2AgCl + 1Ca(NO₃)₂

Every formula now has a coefficient. The equation should be balanced.

Check:

Atom On the left  On the right

  Ag              2                     2

  N                2                     2

  O                6                     6

  Ca              1                      1

  Cl               2                     2

The balanced equation is

2AgNO₃ + CaCl₂ ⟶ 2AgCl + Ca(NO₃)₂

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
