The Faruq family uses 548 liters of water per day.

Chemistry
1 answer:
Radda [10]3 years ago
4 0

Answer:

11508 liters

Explanation:

The Faruq family uses 548 liters of water per day.  The Chammas family uses 3 times as much water  per day. How much water does the Chammas family use per week?

Solution:

The amount of water used by the Chammas family is three times that of the Faruq family per day, hence:

Amount of water used by Chammas family in a day = 3 * water used by Faruq family in a day

Amount of water used by Chammas family in a day = 3 * 548 = 1644 liters

The amount of water used by the Chammas family in a week = 1644 liters per day * 7 days in a week = 11508 liters

Therefore 11508 liters of water was used by the Chammas family in a week

morpeh [17]

Answer:

Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)

Explanation:

In writing the cell notation for an electrochemical cell, the anode is written on the left hand side while the cathode is written on the right hand side. The two half cells are separated by two thick lines which represents the salt bridge.

For the cell discussed in the question; the Mn(s)/Mn^2+(aq) is the anode while the Co^2+(aq)/Co(s) half cell is the cathode.

Hence I can write; Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)

Approximately how many particles are in 2 moles?
schepotkina [342]

Answer:

1.2\times10^2^4 particles in 2 moles.

Explanation:

The number of particles that are contained in one mole, the international unit of amount of substance: by definition, exactly 6.022×10²³, and it is dimensionless. It is named after the scientist Amedeo Avogadro.

It is also known as Avogadro's constant.

∴ Number of particles in one mole = 6.022\times10^2^3

∴ Number of particles in 2 mole = 2 times Number of particles in one mole

∴ Number of particles in 2 mole=2\times6.022\times10^2^3=12.044\times10^2^3\approx1.2\times10^2^4

Hence there are 1.2\times10^2^4 particles in 2 moles.

Determine whether the disruption of the bonds or attractions occurs during protein hydrolysis or protein denaturation.
Aleonysh [2.5K]

Answer:

The disruption of the bonds or attractions occurs during protein hydrolysis which results in the loss for the primacy structure. The peptide bonds is the bond affected in this scenario.

The disruption of the bonds however only exist in the process of denaturation and this results in a change in the confirmation which could be secondary, tertiary, and quaternary structural related. And example of the bonds affected include salt bridges, disulfide bridges, hydrogen bonds etc.
