A recipe calls for 0.8 oz of cheese. If I make 35 batches of this recipe, how many ounces of cheese do I need?

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

uh process of elimination

Temperature change, phase change to liquid or gas are all physical changes not chemical reactions. A color change indicates a chemical reaction has taken place.

Chemical changes are taking place by the breaking or making of chemical bonds. It results in the formation of a new product which is having different properties than the initial substances.

Physical changes does not involve any change in chemical bond. Phase changes, change in size, shape, conductivity, solubility etc. are physical changes. A change in temperature phase conversion into gas or liquid are all physical changes.

A change in color indicates that a new product is formed there. For  example reddish brown rust is iron oxide formed by the reaction of Fe with oxygen. Therefore, option c is correct.

Explanation:

Answer:

Heres a very LONG answer-

The real answer:

Its in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Explanation:

Molar mass of Cobalt (II) chloride = 129.8g/mol

Moles of CoCl2 = 9.32/129.8 = 0.0718mol

Mass of H2O lost after heating = 15.80 - 9.32 = 6.48g

Moles of H2O = 6.48/18 = 0.36mol

Mole ratio of CoCl2 : H20

= 0.0718mol : 0.36mol

= 1 : 5

Hence the formula is CoCl2 . 5H2O, which is Copper (II) chloride pentahydrate.

Answer: they are called electrical conductors.

Mass of ammonia produced : 121.38 g

Given

Reaction

3H₂(g) + N₂(g) ⇒ 2NH₃(g)

100g of N₂

Required

Ammonia produced

Solution

mol of N₂ :

[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{100}{28}\\\\mol=3.57[/tex]

From the equation, mol ratio of N₂ and NH₃ = 1 : 2, so mol NH₃ :

[tex]\tt \dfrac{2}{1}\times 3.57=7.14~moles[/tex]

mass of NH₃(MW=17 g/mol) :

[tex]\tt mass=mol\times MW\\\\mass=7.14\times 17\\\\mass=121.38~g[/tex]
