Answer: option C

Explanation:

Oxidation means you loss of electons (LEO) and Reduction is gain of electrons.

Example: sodium gets oxidized by the loss of one electron as shown below

Na------> Na+ + 1e-

Here Na lost one electron hence it is oxidation

Change in oxidation no: 0 to +1

A 275 g sample of a metal requires 10.75 kJ to change its temperature from 21.2 oC to its melting temperature, 327.5 oC. What is
Vlada [557]

Answer:

c=0.127\ J/g^{\circ} C

Explanation:

Given that,

Mass of the sample, m = 275 g

It required 10.75 kJ of heat to change its temperature from 21.2 °C to its melting temperature, 327.5 °C.

We need to find the specific heat of the metal. The heat required by a metal sample is given by :

Q=mc\Delta T

c is specific heat of the metal

c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{10.75\times 10^3\ J}{275\times (327.5 -21.2)}\\\\=0.127\ J/g^{\circ} C

So, the specific heat of metal is 0.127\ J/g^{\circ} C.

1. Energy in foods is provided by
ELEN [110]

Answer:

Energy in foods is provided by macro-nutrients.

Explanation:

Nutrients are “environmental substances” used for growth, energy, and bodily functions of the  organisms. Those nutrients that are required  in larger amounts are called macro-nutrients.

There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in  form of “calories”. For example:

  • In carbohydrates, there are '4 calories' of energy per gram.
  • In proteins, there are '4 calories' of energy per gram.
  • And in lipids, there are '9 calories' of energy in one gram.

This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.

rjkz [21]

Answer:

D

Explanation:

Protons and Neutrons both have a mass of about 1 amu so you add them but electrons have a mass of 0 amu so they are left out.
