Answer:
10460J
Explanation:
Given parameters:
Mass of water sample = 100g
Initial temperature = 35°C
Final temperature = 60°C
Unknown:
Amount of energy absorbed by water = ?
Solution:
The amount of energy absorbed by water is mathematically expressed below;
H = m C ΔT
H is the amount of energy
m is the mass
C is the specific heat capacity of water = 4.184J/g°C
ΔT = 60°C - 35°C = 25°C
Now insert the parameters and solve;
H = 100 x 4.184 x 25 = 10460J
1. Heart
2. Circulatory system
3. The circulatory system delivers oxygen and nutrients to cells and take away water .
4. Your heart is a muscle and it’s job is to pump blood throughout your circulatory system.
Hope this helps :)
Have a great day!
Answer:
70.88 mL volume of 1.27 M of HCl is required.
Explanation:
Given data:
Initial volume = ?
Initial molarity = 1.27 M
Final volume = 197.4 mL
Final molarity = 0.456 M
Solution:
Formula:
M₁V₁ = M₂V₂
Now we will put the values in formula.
1.27 M × V₁ = 0.456 M × 197.4 mL
V₁ = 0.456 M × 197.4 mL/1.27 M
V₁ = 90.014M.mL/1.27 M
V₁ = 70.88 mL
70.88 mL volume of 1.27 M of HCl is required.
Answer:
Response is below
Explanation:
The different types of mining are underground, surface, placer, and in-situ. Underground mining uses various materials to excavate resources from beneath the surface of the Earth. Surface mining is a category of mining that in which soil and rock overlying the mineral deposit are removed. Placer mining is the mining of stream bed deposits for minerals. In-situ mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit.
