<u>Answer:</u> The final temperature will be 
<u>Explanation:</u>
Calculating the heat released or absorbed for the process:
In a system, the total amount of heat released is equal to the total amount of heat absorbed.
OR
......(1)
where,
C = heat capacity of water = 
= mass of water of sample 1 = 100.0 g
= mass of water of sample 2 = 71.0 g
= final temperature of the system = ?
= initial temperature of water of sample 1 = 
= initial temperature of the water of sample 2 = 
Putting values in equation 1, we get:
Hence, the final temperature will be
Explanation:
my God what kinda learning you doing?
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
<span>3.26 x 1.52 = 13.26 x M2</span>
<span>M2 = 0.37 mg/mL</span>
Answer is D - Argon atom
Potassium has atomic number as 19. Hence, number of protons = 19
If the atom is neutral,
number of protons = number of electrons = 19
Hence, the electron configuration of potassium (K) is
1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹
Potassium ion is formed by losing an electron. Then the number of electrons = 19 - 1 = 18
Electron configuration of K⁺ is 1s² 2s² 2p⁶ 3s² 3p⁶.
This is same as the electron configuration of Ar which has 18 electrons.
Answer:Sugars are actively transported from source cells into the sieve-tube companion cells, which are associated with the sieve-tube elements in the vascular bundles. ... The co transport of a proton with sucrose allows movement of sucrose against its concentration gradient into the companion cells.
