The combustion of propane gas is used to fuel barbeque grills. If 4.65 moles of propane, C3H8, are burned in a grilling session,

how many moles of carbon dioxide gas are formed? C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l)

Answer:

<h3>moles of carbon dioxide=13.95mol</h3>

Explanation:

First wrie down the balance chemical reaction:

C_3H_8(g) + 5 O_2(g) \rightarrow 3 CO_2(g) + 4 H_2O(l)

Combustion reaction: The reacion in which hydrocarbon is burnt in the presence of oxygen gas and it releases heat and this reaction exothermic because heat of cumbustion is negative.

eg. burning of methane

By using unitry method,

From the above balanced reaction it is clearly that,

from 1 mole of propane 3 moles of carbon dioxide is formed

there fore,

from 4.65 mole of propane 3 \times 4.65 moles of carbon dioxide will form

moles of carbon dioxide=13.95mol

What is the molarity of na+ in a solution of nacl whose salinity is 5.6 if the solution has a density of 1.03 g/ml?
pantera1 [17]
Salinity has units of grams NaCl or salt per kilogram solution. We can use the density given and the molar mass of the salt to convert from salinity to molarity. We do as follows:

( 5.6 g / kg ) ( 1.03 kg / L ) ( 1 mol / 58.44 g ) = 0.0987 mol NaCl / L

How does removing trees affect nitrogen cycling in a forest ecosystem?
nikdorinn [45]

Explanation:

The roots of trees in a forest are colonized by symbiotic fungi called mycorrhizae. These fungi are significant nitrogen fixers because they harbor nitrogen-fixing bacteria. They convert atmospheric nitrogen into nitrates and nitrites that can be absorbed by plants. The plants use these forms of nitrogen to build biomolecules such as DNA and amino acids.This nitrogen is transferred up the food chain. Eventually the nitrogen is again recycled by denitrifiers when the organisms die.

Removing trees will disrupt the symbiotic relationship with mycorrhizae, stime the nitrogen cycle in the forest.

Thermal energy is the _____ and internal energy is the _____
Lubov Fominskaja [6]

Answer:

Average kinetic energy of the particles in an object.

Total energy of particles in an object.

Explanation:

Thermal energy is the _average kinetic energy of the particles in an object____ and internal energy is the ___total energy of particles in an object__.

Thermal energy is a form of kinetic energy. Kinetic energy is due the change in position of a body or the motion of a body. When we apply thermal energy to a system, the particles gain kinetic energy which causes the motion of its particles.

The internal energy of system is the sum of all the total energy of particles contained in the object. It is given as the change between the kinetic and potential energy of a system.
