Answer:

The answer to your question is 1.2 moles

Explanation:

Reaction

N₂(g) + 3H₂ (g) ⇒ 2NH₃

Check if the reaction is balanced

Reactants Elements Products

2 N 2

6 H 6

As the number of reactants is equal to the number of products, this reaction is balanced.

Now, calculate the moles of ammonia produced using proportions

1 mol of nitrogen -------------- 2 moles of ammonia

0.6 mol of nitrogen ----------- x

x = (0.6 x 2) / 1

x = 1.2 / 1

x = 1.2 moles of ammonia are formed

CH4 (g) yields C(g) + 4H (g) (reaction for expansion)

Answer:

Here's what I find.

Explanation:

$\rm CH$_{4}$(g) $\, \rightleftharpoons \,$ C(g) + 4H(g)$

$\text{Same} =\begin{cases}1. & \text{The number of atoms of each element}\\2. & \text{The state of the methane molecules}\\4. &\text{The state of the carbon atoms}\\\end{cases}$

$\text{Different} =\begin{cases}3. & \text{The enthalpy change of the reaction}\\\end{cases}$

The sign of ΔH changes when you reverse the reaction.

Everyone who is thin is in shape. A. True B. False

MAVERICK [17]

Answer:

false; one could be in thin shape but thay doesnt always mean they are healthy, or fit...there is always a chance there can be malnutrition or they have a good metabolism, but to be in shape, there should be a good balance of fat and muscle in the body

The label on a ready-to-eat cereal box indicates that 1 cup contains 32 grams of carbohydrate, 4 grams of protein, and 2 grams o

eduard

Energy given by carbohydrates present in one cup = $32 g * \frac{4 kcal}{1 g}$ = 128 kcal

Energy given by proteins present in one cup = $4 g * \frac{4 kcal}{1 g} = 16 kcal$

Energy given by fat in one cup = $2 g * \frac{9 kcal}{1 g} = 18 kcal$

Total energy in one cup of cereal box = 128 kcal + 16 kcal + 18 kcal = 162 kcal

Energy present in two cups = [tex] 2 cups * \frac{162 kcal}{1 cup} *

= 324 kcal

NAME the four phases of matter and DESCRIBE how the intermolecular forces and kinetic energy change as you change phases.

weqwewe [10]

Answer: Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition. Intermolecular forces are forces between molecules that determine the physical properties of liquids and solids. 11.2 Vaporization and Vapor Pressure— vaporization is the conversion of a liquid to a gas (vapor), and the quantity of heat associated with this phase change is known as the enthalpy (heat) of vaporization. When kinetic energy is increasing molecules are simply moving faster. However, when the potential energy is increasing molecules are changing phases. Therefore, when the potential energy is increasing is when the molecule is changing phases. Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing). ... Changing the amount of heat energy usually causes a temperature change.

HOpe this helps..... Stay safe and have a Merry Christmas!!!!!!!!!! :D
