Answer:
Explanation:
The equation for this chemical reaction is:
2Ca + O2 -> 2CaO
So 2 moles of Ca react with 1 mole of O2 to form 2 moles of CaO.
Given 3.9 moles of Ca and 2.35 moles of O2,
Ca is the greater reactant as it will be used up.
O2 is the reactant in excess and there will be 2.35 - 3.9/2 = 0.4 moles left.
As mass of 1 mole of O2 is 32g, 0.4 moles of O2 = 0.4 * 32 = 12.8g
Moles of CaO formed = moles of Ca = 3.9
As mass of 1 mole of O2 is 56g, 3.9 moles of CaO = 3.9 * 56 = 218.4g of CaO
The correct answer to this open question is the following.
The appeal is John Adams using in this letter to a fellow colonist who supported the king was logos, the appeal to logic or reason that is supported by arguments.
John Adams tried to convince those loyalists to change their minds and support the Revolutionary movement. He used logic because he stated the reasons and gave arguments. He literary wrote: "That a representation in parliament is impracticable, we all agree; but the consequence is, that we must have a representation in our supreme legislatures here. This was the consequence that was drawn by kings, ministers, our ancestors, and the whole nation, more than a century ago, when the colonies were first settled."
Let's remember the other two rhetoric devices: Pathos and Ethos. Pathos is the use of emotion to appeal to audiences. Ethos is the use of the experience or reputation of the speaker to convince an audience.
1)d. The quantity of a product that consumers are willing and able to buy at each unit price
2)C. The product has a lower price
3)c. The quantity demanded for chips will decrease and the demand for salsa will decrease.
4)I didn't understand your question about this one but I can explain the graph:-)
according to this diagram
the supply curve has shifted backward i.e supply is decreased so, with the decrease in supply the price of good increases and as a result of increased price the quantity demanded decreased.
5)B. Average consumer income has decreased, with Good A being an inferior good. ( because as you can see in the diagram that demand for good A is increased)
demand for inferior goods increases with the decrease in income. For example: if your income decreases you'll start travelling from bus instead of train.
6)B. Stacy wanted ice cream a bit more than a cupcake but chose the cupcake when the price of ice cream increased.
