Answer: Objects with like charge repel each other.
Carbon monoxide reacts with hemoglobin of the blood to form carboxyhemoglobin. The absorption of oxygen worsens, oxygen starvation develops. At a lethal dose, death occurs within 20 days.
Answer:
Adding salt to the water increases the density of the solution because the salt increases the mass without changing the volume very much. When you add table salt (sodium chloride, NaCl) to water, the salt dissolves into ions, Na+ and Cl-. The volume increases by a small factor, but the mass increases by a bigger factor.
Explanation:
The moles of I2 that will form 38.58g of Ni3 is 0.147 moles
calculation
write the equation for reaction for formation of Ni3 from I2 and N2
that is 3I2 + N2 = 2NI3
find the moles of Ni3 formed = mass/molar mass
= 38.58g/ 394.71 g/mol = 0.098 moles
by use of mole ratio between I2 to NI3 which is 3 :2 the moles of I2
= 0.098 x3/2 = 0.147 moles
