Calories in 1 egg = 78 cal  

Calories in 2 eggs = 156 cal

Calories in 1 slice toast = 75 cal  

Calories in 1 slice toast = 150

Calories in one tablespoon of butter = 102 cal

Calories in 9 oz orange juice = 115 cal

Therefore, total calories = 156 +150 +102 +115 = 523 cal

A certain metal fluoride crystallizes in such a way that the fluoride ions occupy simple cubic lattice sites, while the metal io
Bezzdna [24]

Answer:

MF_2

Explanation:

In a simple cubic lattice lattice, the atoms are present at the eight corners of the cibe.

Since it is mentioned that the fluorine is present at the corners and also 1 corners are shared by 8 unit cells. So, share of atom in one unit cell is:- 8\times \frac{1}{8}=1

Also, the metal, M occupy half of the body centre. A cube has only one body centre. So, share of M in each unit cell:- \frac{1}{2}

Thus, the formula is:-

M_{\frac{1}{2}}F Or simplifying MF_2

Which statement is true: Mg -> Mg2+ + 2e-
Damm [24]

Answer:

(2) Mg²⁺ loses 2 electrons.

Explanation:

Let's consider the following half-reaction.

Mg ⇒ Mg²⁺ + 2 e⁻

Magnesium is a metal that loses 2 electrons to fulfill the octet rule. When magnesium loses electrons, the oxidation number increases from 0 to +2. This kind of half-reaction is known as oxidation, and has to be accompanied by a reduction of another species.

What pressure does 3.54 moles of chlorine gas at 376 k exert on the walls of it 51.2 l container? I'm Lazy sooooo
Lilit [14]

Answer:

The answer to your question is P = 2.13 atm

Explanation:

Data

Pressure = ?

number of moles = 3.54

Temperature = 376 °K

Volume = 51.2 L

R = 0.08205 atm L/mol°K

Formula

PV = nRT

- Solve for P

  P = nRT / V

- Substitution

  P = (3.54)(0.08205)(376) / 51.2

- Simplification

  P = 109.21 / 51.2

Result

 P = 2.13 atm
