Answer:
Explanation:
Bohrium's most stable isotope, bohrium-270, has a half-life of about 1 minute. It decays into dubnium-266 through alpha decay. Since only a few atoms of bohrium have ever been made, there are currently no uses for bohrium outside of basic scientific research.
Answer:
Mass = 57.05 g
Explanation:
Given data:
Volume of SO₂ = 20.0 L
Temperature = standard = 273 K
Pressure = standard = 1 atm
Mass of SO₂ = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
n = PV/RT
n = 1 atm × 20.0 L / 0.0821 atm.L/ mol.K× 273 k
n = 20.0 / 22.41/mol
n = 0.89 mol
Mass of SO₂:
Mass = number of moles × molar mass
Mass = 0.89 mol × 64.1 g/mol
Mass = 57.05 g

(A)Diffusion and osmosis
<u>(B)Engulfing and transport proteins
</u>
(C)Osmosis and engulfing
(D)Transport proteins and diffusion
Water is your answer!!!!!!!!!
Answer : The molar specific heat of Ni is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of Ni = ?
= specific heat of water =
= mass of Ni = 1000 g
= mass of water = 1 kg = 1000 g
= final temperature of water =
= initial temperature of Ni =
= initial temperature of water =
Now put all the given values in the above formula, we get
Now we have to calculate the molar specific heat of Ni.

Therefore, the molar specific heat of Ni is,
