In any balanced
chemical reaction, the elements or compounds which are located in the left hand
side of the arrow is the reactants while those that are location on the right
hand side are the products, therefore the product here is:
<span>CaO or Calcium Oxide</span>
Some Gases are lighter than air
Remember,Air is a mixture of gases
So you cant tell!
It depends on the gas
Hope i helped
Answer:
Option B is correct.
Another name for equilibrium price is **market-clearing price**
Explanation:
Equilibrium price is defined as the price at which the quantity of products/goods/services demanded is equal to/matches the quantity of products/goods/services supplied.
The equilibrium price is also called the market clearing price because, at this price, there is no supply leftover (surplus) or demand leftover (deficit). The market is literally cleared!
Answer:
The answer to your question is:
a) 0.023 mol of CdS
b) 0.12 mol of MoO3
c) 7.3 mol of AlPO4
Explanation:
a) CdS
MW = 112.4 + 32
= 144 g
144g ------------------ 1 mol
3.28g -------------- x
x = (3.28 x 1) / 144
x = 0.023 mol
b) MoO3
MW = 96 + 3(16) = 144 g
144g ------------------- 1 mol
17.5g ----------------- x
x = (17.5 x 1) / 144
x = 0.12 mol
c) AlPO4
MW = 27 + 31 + 4(16)
MW = 122 g
122 g ------------------ 1mol
890 g ------------------ x
x = (890 x 1) / 122
x = 7.3 mol of AlPO4
Answer:
i would say 10, so the anser is A.
Explanation:
because there are the same number of protons and electrons, therefore for a regular O, you are supposed to have only 8 protons, but it is charged, thus, whatever the charge is will be taken into consideration into how much the proton and electron doe it have. Thus, for this case, it has 10, because the charge is negative and you have 8 electron plus 2 = 10.
