Answer:
The answer to your question is given below
Explanation:
The balanced equation for the reaction is given below:
CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)
1. Writing an expression for the equilibrium constant, K.
The equilibrium constant, K for a reaction is simply the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.
Thus, we can write the equilibrium constant, K for the reaction as follow:
CaO(s) + CH4(g) + 2H2O(g) <=> CaCO3(s) + 4H2(g)
K = [CaCO3] [H2]⁴ / [CaO] [CH4] [H2O]²
2. Based on the value of K, more products will be in the equilibrium mixture since the value of K is a positive large number.
Answer:
11.31 g.
Explanation:
Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (mass/molar mass)of NaCl/(V of the solution (L)).</em>
<em></em>
<em>∴ mass of NaCl remained after evaporation of water = (M)(V of the solution (L))(molar mass)</em> = (0.45 M)(0.43 L)(58.44 g/mol) = <em>11.31 g.</em>
Answer:
im pretty sure its b. sand and iron
ik that magnetism easily separates iron
You always adjust numbers and it will be before the element
so you Neva add or change a subscript
Plants serve as the main source of nutrition for humans as well as provide many products for human use, such as firewood, timber, fibers, medicines, dyes, oils, and rubber.
Plants are multicellular eukaryotic organisms whose mode of nutrition is mainly autotrophic.
Plants play many important roles in life more especially that of producing food on which many other organisms depend on.
Some of the important ways by which plants support human life include:
- Provision of food: plants trap the energy of the sunlight and through the process of photosynthesis produce food on which other living organisms such as animals depend on.
- Provision of oxygen: during the process of photosynthesis, plant release oxygen into the atmosphere which is needed by animals for respiration.
- Recycling of water: through the process of transpiration occurring in leaves of plants, water is recycled in nature.
- Provision of other products such as timber, fibers, medicines, dyes, oils, and rubber.
Therefore, plants serve as the main source of nutrition for humans as well as provide many products for human use, such as timber, fibers, medicines, dyes, oils, and rubber.
