Answer:

Mark me as Brainilist please!!

Explanation:

Oxides and their hydroxide counterparts made possible the industrial innovations we live in. Indeed, steel is a member of this family. Earth's crust contains them in vast quantities, making them the second most common element.

On a molecular scale, you would find that each oxygen atom is coupled with metal or semimetal atoms that fill in the gaps between them in oxide minerals. Oxides are divided into two groups: simple oxides, with a single metal or semimetal added, and complex oxides, where several metals can be incorporated into the molecule's structure. Hydroxides, on the other hand, are composed of metal ions attached to a highly reactive hydroxide ion (OH). Minerals formed by hydroxide are softer and less dense than oxides and usually form at lower temperatures.

A food product contains 15 g of carbohydrates, 5 g of protein and 4 g of fat. How many calories are in one serving of this produ
Basile [38]

Answer: 116 calories of energy

Explanation:

A calorie is a non-standard unit of energy.

On combustion,

1 gram Carbohydrates = 4 calories,

1 gram protein = 4 calories,

1gram fat = 9 calories.

Therefore,

15 grams of carbohydrates = (15*4) = 60

5 grams of protein = (5*4) = 20

4 grams of fats = (4*9) = 36

Then add up: 60 + 20 + 36 = 116 calories of energy

13. What is the charge of an aluminum ion that has 13 protons and 10 electrons?
Ksenya-84 [330]

Answer:

+ 3

Ex planation:

Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).

hope this helps!

What would a pressure reading of 565 torr be in units of atmospheres?
mamaluj [8]

<u>Given:</u>

Pressure = 565 torr

<u>To determine:</u>

Corresponding pressure in atmospheres

<u>Explanation:</u>

Pressure is commonly expressed in units like:

Atmosphere (atm), Torr or mmHg

The SI unit is atm, where

760 torr = 1 atm

Thus, a pressure reading of 565 torr corresponds to:

565 torr * 1 atm/760 torr = 0.743 atm
