What is one way to move carbon from fossil fuels into the atmosphere?.

Answers

One way to move carbon from fossil fuels is by making coal cleaner is carbon capture and storage, or CCS.In CCS, which can be used at both coal and natural gas plants, CO2 gas is captured before it can escape to the atmosphere. The gas is then turned into a fluid and injected deep underground

You want to spread honey on your toast, but it is too thick to spread. What term from today's lesson describes the "thickness" of the honey? How could you change the "thickness" of the honey?

Answers

Answer:

The enthalpy change of the reaction comes out to be -890 Kj Explanation:To calculate the enthalpy of the reaction divided in multiple steps, we use Hess's law. This law states that the heat absorbed or evolved in a given chemical equation remains same whether the process occurs in one step or several steps.To apply this law, the enthalpy of the chemical equation is treated as ordinary algebraic expression and it can be added or subtracted to form the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes that occur during intermediate reactions.

Explanation:

Answer:

A few definitions:

1. A river delta is a land-form created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or another river that cannot carry away the supplied sediment.

2. The fourth letter of the Greek alphabet ( Δ, δ ), transliterated as ‘d’.

The combustion of c2h4(g) is represented by the equation above. (a) use the enthalpies of formation in the table below to calculate the value of δh∘1 for the reaction

Answers

Based on Hess law of constant heat summation, the enthalpy of the combustion of C2H4 can be calculated from the heat of formation values of the products CO2 and H2O.

What is a combustion reaction?

A combustion reaction is a reaction between a substance and oxygen in which light and large amounts of heat is given off.

The amount of heat evolved when one mole of that substance reacts completely with oxygen is known as the enthalpy of combustion of that substance.

The equation of the combustion of C2H4 is given below:

C2H4 + 3 O2 ---> 2 CO2 + 2H2O

The enthalpy of the combustion of C2H4 can be calculated from the heat of formation of the products CO2 and H2O based on Hess law.

An unknown salt was dissolved to make a total 1.53g of solution. The temperature of the water decreased from
24.3C to 20.3C when 8mol were dissolved. What is the heat of solution in J/mol?

Answers

Answer:

3.213J/mol

Explanation:

first specific heat capacity of water = 4200J/Kg K

Q=mass×temperature difference×specific heat capacity

Q=1.53×(24.3-20)×4200

Q=25.704 J

heat of solution= quantity of heat ÷ amount of substance

heat of solution= 25.704÷8

heat of solution= 3.213J/mol

To prevent inhaling spill vapors. Avoid attempting to clean up a spill if it is in an area that isn't well-ventilated. Send out a call for help to respond to and clean up the spill.

Additionally, more severe side effects include breathing problems, coughing, wheezing, a faint feeling, or weakness that may result from significant chemical exposure. The most dangerous substances can cause immediate collapse, convulsions, and possibly even death.

Wearing personal protection equipment (often known as "PPE") helps reduce exposure to a number of risks. Gloves, foot, and eye protection, protected hearing equipment (earplugs, muffs), hard helmets, respirators, and complete body suits are a few examples of PPE.
