Mrac [35]3 years ago
6 0

Hello, Brainly User!

A heterogeneous equilibrium reaction is when there are different phases in the reaction. An equilibrium reaction is a reaction that can go in both the forward and reverse directions, and the concentrations of the reactants and products remain the same.

So therefore, your answer is A. Heterogeneous!

Hope i helped and i was honored to answer your question!

Have a great day..

Does a laboratory balance measure mass or weight
kolezko [41]
A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.

So the mass of the object can be found by dividing the weight by gravitational constant.

The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.

Hope that helps :)

Gaseous hydrogen and oxygen can be prepared in the laboratory from the decomposition of gaseous water. The equation for the reac
monitta

Answer:

  • 75.5 g O₂ (g) can be produced from 42.6 g of H₂O (g)

Explanation:

<u>1) Balanced chemical equation (given):</u>

  • 2H₂O(g) → 2H₂(g) + O₂(g)

<u>2) Mole ratios:</u>

  • 2 moles H₂O(g) : 2 moles H₂(g) : 2 moles O₂(g)

<u>3) Calculate the number of moles of reactant (H₂0):</u>

  • number of moles = mass in grams / molar mass

  • molar mass of water: 18.015 g/mol

  • mass in grams of water: 42.6 g

  • number of moles = 42.6 g / 18.05 g/mol = 2.36 moles H₂O

<u>4) Set a proportion using the mole ratio  O₂ to H₂O and the actual number of moles of H₂O:</u>

  • 2 moles O₂ / 2 moles H₂O = x / 2.36 moles H₂O

  • x = 2.36 moles O₂

<u>5) Convert 2.36 moles O₂ to grams:</u>

  • mass in grams = number of moles × molar mass

  • mass = 2.36 moles × 32.00 g/mol = 75.5 g O₂

How do everyday activities like driving a car and using electricity lead to global warming ?
Sati [7]
Both driving a car and using electricity produce several greenhouse gases which can lead to global warming.Greenhouse gases are gases that, when released into the atmosphere, trap the heat from the sun's energy. Every day the energy from the sun reaches the earth. Some of the energy is reflected back into space and some of the energy is trapped by the earth's atmosphere. Most of the time the energy being trapped by the atmosphere serves to warm up the earth, so that the temperature does not fluctuate dramatically. In this way the atmosphere acts like a greenhouse - trapping the warmth in. One of the ways that electricity is made is by burning fossil fuels, like coal or fuel. When a fuel is burnt, some of the products are: carbon dioxide, carbon monoxide, and water - all of these gases are greenhouse gases. In a similar way driving a car also burns fossil fuels, and this will produce the same gases.<span>Before lots of fossil fuels were burnt the greenhouse gases in the atmosphere would have been moderated by the carbon cycle. However, if we burn excess fossil fuels we are producing excess greenhouse gases. This can cause more heat to be trapped by the atmosphere and therefore the global temperature will start to rise - global warming. hope i helped </span>
