Answer:
delta
Explanation:
A river delta is a landform where the mouth of a river flows into an ocean, sea, desert, estuary, lake or another river.
The scientists responsible for testing the hypothesis are already famous
<span>1. Balance the reaction
Cu + 2AgNO3 → Cu(NO3)2 + 2Ag
2. Find the limiting [divide moles of reactant by their balancing numbers]
Cu: 4.2/1 =4.2
AgNO3: 6.3/2= 3.15
AGNO3 is the limiting
How many moles of silver metal will be formed?
The ratio between the limiting reactant and silver is 2:2 or 1:1
therefore 6.3 moles of silver will be formed.
How many moles of excess reactant will be left?
Since each mole of copper is equal to 2 moles of AgNO3. divide 6.3 by 2 then minus it from coppers moles
6.3/2 = 3.15
4.2-3.15 = 1.05 moles of copper will be left

Answer:
Lisa sold 75 boxes of cookies all together
Explanation:
The 1st week she sold 18 boxes of cookies
The 2nd week she sold 18 of cookies
The 3rd week she sold 12 boxes of cookies
The 4th week she sold 12 boxes of cookies
The 5th week she sold 15 boxes of cookies
So, number of cookies sold altogether is 18+18+12+12+15= 75
