Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".
Imagine disease kills 85 percent of the wolf population. How will it affect the other organisms?
Answer:
There would most likely be an overpopulation of the animals the wolfs ate.
Explanation:
Answer:
Many populations will grow way to much. Also others will drop in numbers drastically.
Explanation:
Due to the fact that wolves are predators, the prey they eat will grow 85% more. Now, 85% of the wolf population dies, that`s a lot of prey not eaten. Then the prey that are predators to other animals who are over hunted by their predators will most likely drop in numbers drastically, by I mean 85%. This will throw the ecosystem off so much, humans could be at grave risk.

The volume of a gas is 200mL at 2.0atm. What will it's volume be at 4.0atm?
Answer:
V = 100 ml
Explanation:
P1V1 = P2V2
P1 = 2.0 atm
V1 = 200ml
P2 = 4.0 atm
V2 = ?
(2.0)(200) = (4.0)V2
400 = (4.0)V2
V2 = 100
The new pressure will be

A gas occupies a volume of 560 cm at a temperature of 120 °C. To what temperature
must the gas be lowered if it is to occupy 400 cm?
Answer:
7.56°C is the temperature when the gas occupies 400cm³
Explanation:
Based on Charles's law, the volume of a gas is directly proportional to its absolute temperature under constant pressure. The equation is:
V₁T₂ = V₂T₁
Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.
Computing the values:
V₁ = 560cm³
T₂ = ?
V₂ = 400cm³
T₁ = 120°C + 273.15 = 393.15K
560cm³*T₂ = 400cm³*393.15K
T₂ = 280.71K - 273.15 =
7.56°C is the temperature when the gas occupies 400cm³Part B

the moon is 250,000 miles away. How many inches is it from earth?
Answer:
1.584e10 = 15,840,000,000,000
Explanation:
250,000 miles
multiply the length value by 63360
25e4 x 63360
= 1.584e10
Answer: 110000000 inches
Explanation: Since the moon is 1,320,000,000ft away from the earth you divide 1,320,000,000ft with 12 to get your final answer 110000000

complete combustion of wax takes place in____ zone of a candle flame.
Answer:
outer or non - luminous
Explanation:
complete combustion of wax takes place in non-luminous zone of a candle flame.
Answer:
A complete combustion of wax takes place in outer zone of a candle flameExplanation:
The middle zone is yellow and luminous because As it is an oxygen-depleted zone, insufficient oxygen exists to burn all of the wax vapor. ... The outer zone is the area where the flame is the hottest and complete combustion of wax takes place.In the USA 3.5 millions pounds of whole milk are used daily to make milk chocolate how many gallons of milk are used daily

how many grams of NH3 are in 45.9
A 5.00 gram sample of water is heated so that its temperature increases from 10.0°C to 15.0°C. What is the
total amount of energy absorbed by the water?
Answer:
15.0°C
Explanation:
hope it helps
Heat Capacity
The heat capacity of a substance can be defined as the amount of heat required to change the temperature by a given amount the SI unit is joules per kelvin
The energy absorbed by the water is 105 joules
Given data:
mass of water = 5 grams
Change in temperature = 10 degrees from 15 degrees
The expression for the Quantity of heat is given by
Q = m x c x Δθ
Where m =mass
c = specific heat capacity and
Δθ = change in temperature
c = 4.2J/g/degrees
Q = 5 x 4.2 x (15 - 10)
Q = 5 x 4.2 x 5
Q = 105Joules
