Answer:
A. The neutrons and electrons are in the wrong place.
Explanation:
The atom's nucleus contains both protons and neutrons, whilst the electrons are arranged in shells around the nucleus.
1000 mL=1L
25 mL = 0.025 L
125 mL = 0.125 L
M1V1=M2V2
0.15(0.125) = M2(0.025)
0.01875 = M2(0.025)
0.75 = M2
0.75 M
Answer:
Yes N3- is correct ion notation. The N element is in the form N2 . Also it is a triple covalent bond and so this correct
Answer:
A fund manager has portfolio worth $50 million with a beta of 0.87. The manager is concerned about the performance of the market over the next two months and plans to
use 3-month future contracts on the S&P 500 to hedge the risk.
The answer to this question is change in temperature will be 6.1 and specific specific heat capacity of metal will be 1698.36.
According to the formula of Calorimetry
Q = msΔT
where, Q = Quantity of heat absorbed (in joules)
M = Mass of water sample given (in kilogram)
S = specific heat capacity of metal
ΔT = Change in temperature
We have given,
Mass as 25 gram which is equal to 0.025 Kg.
Change in temperature as 6.1
Quantity of heat absorbed as 259 J
Applying to the formula of Calorimetry
Q = msΔT
259 = 0.025 × s × 6.1
s = 1698.36
So, specific heat capacity of metal came out to be 1698.36 and the change in temperature will be 6.1
