How can mechanical waves help in the treatment of cancer?
Andreas93 [3]

Mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.

<h3>What is mechanical wave?</h3>

A mechanical wave is a wave that requires material medium for its propagation, example include;

  • water waves,
  • sound waves, and
  • seismic waves.

<h3> Mechanical waves in treatment of cancers</h3>

Sound wave in example of mechanical wave because it requires material medium for its propagation.

High-frequency sound waves (HIFU) is used in the  treatment  of cancer because the strong beam generates heat which is directed to a specific part of a cancer.

The heat generated destroys the cancer cells.

Thus, mechanical waves can help in the treatment of cancer due to heat generated by the high frequency waves.

Sphinxa [80]

Answer:

P_4_{(I)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}

Explanation:

The first step is:

P_4_{(I)}+5O_2_{(g)}\rightarrow 2P_2O_5_{(g)}

Second step is:

P_2O_5_{(g)}+3H_2O_{(l)}\rightarrow 2H_3PO_4_{(l)}

Multiplying second step by 2, and adding both the steps, we get that:

P_4_{(I)}+5O_2_{(g)}+2P_2O_5_{(g)}+6H_2O_{(l)}\rightarrow 2P_2O_5_{(g)}+4H_3PO_4_{(l)}

Cancelling common species, we get that:

P_4_{(l)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}
