Explanation:

Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.

Answer:

Answers may vary. View explanation.

Explanation:

There are every day decisions that may add carbon dioxide to the environment.  

Problems:

  • Burning of fossils fuels.  Example: Using cars as transportation. The average car releases around 4.6 metric tons of carbon dioxide per year.
  • Deforestation. Carbon dioxide is released from dead organisms such as trees. Example: As of 2021, 15 billion trees are lost to deforestation.

Solutions:

  • Instead of taking your car to work or school, carpool with a friend. Riding your bike and taking the bus are also good solutions that help minimize carbon dioxide releases.
  • In spare your time, grab a couple of friends and plant some trees! Even planting just a few trees is a great start to help the planet.

Have a great day!

Titanium dioxide (TiO2) is used extensively as a white pigment. It is produced from an ore that contains ilmenite (FeTiO3) and f
STALIN [3.7K]

Answer:

2928kg of ore are required.

2585kg of the 80% H₂SO₄ solution are required.

Explanation:

To solve this question we need first to find the moles of titanium in 1000kg of TiO₂. Keeping in mind the 89% of descomposition we can find the mass of the ore and the mass of the 80% sulfuric acid required:

<em>Moles TiO₂ -Molar mass: 79.866g/mol-:</em>

1x10⁶g * (1mol / 79.866g) = 12521 moles Titanium

In mass -Molar mass Ti: 47.867g/mol-:

12521 moles Titanium * (47.867g / mol) = 599341.4g of Ti.

As the ore contains 24.3% of Ti:

599341.4g of Ti = 599.34kg Ti * (100 / 24.3) = 2606kg ore

As the descomposition is just of 89%:

2606kg ore * (100 / 89) =

<h3>2928kg of ore are required</h3><h3 />

<em>Mass 80% sulfuric acid:</em>

12521 moles Titanium = 12521 moles H₂SO₄ * (100/89) = 14068.5 moles of H₂SO₄ are required.

In an excess of 50% =

14068.5 moles of H₂SO₄ are required * 1.5 = 21102.8 moles of H₂SO₄.

The mass is:

21102.8 moles of H₂SO₄ * (98g / mol) = 2068075g = 2068kg of sulfuric acid

That is in the 80%:

2068kg of sulfuric acid * (100/ 80) =

<h3>2585kg of the 80% H₂SO₄ solution are required</h3>

What quantity do units represent in a value ?
Mazyrski [523]

A measured value is expressed as a number along with a corresponding unit. The unit represents the dimension of the measured value.

For example:

- Length of an object can be expressed as, value + dimension. for example 10 m where 'm' is the dimension of length; meters

- Volume can be expressed as, value + dimension, for example, 10 L where L is the dimension of volume; Liters.

Ans C) Dimension

lana [24]

Answer:

the equilibrium constant is 1.8 x 10⁻5 and strongly favor the reactants.

Explanation:

the chemical reaction provided for the two equation are the same but different direction i.e a reversible reaction. Assuming, the mass of reactants and product and temperature remain constant.

therefore, the equilibrium constant K, is 1.8 x 10⁻5. this is a very small value of K, thereby strongly favor the backward direction to form reactant.
