Answer;
1 mole
Explanation;
Iodine and hydrogen react according to the following equation to yield hydrogen iodide.
H2(g) + I2(s) = 2HI
Using the mole ratio; the mole ratio of H to I is 1: 1
Thus; 1 mole of hydrogen will require 1 mole of iodine to form 2 moles of hydrogen iodide.
Answer:
c i guess, decrease temperature
Use the D = M/V equation, in which Density can be found by dividing <em>Mass/Volume</em>.
To solve, first find a rectangular prism tub that is filled to a certain level. Next, place the rock inside to find the amount of displacement (or how high the water level goes up.) In this way, you can find the <em>volume of the rock</em>.
Next, solve for the Mass. This can be found by dividing the total weight from the gravitational pull. This would give you the mass.
Finally, to find Density, divide the Mass found with the Volume. This would give you your final answer

Answer:
The claim is untrue.
Explanation:
Given the information from the question. We need to evaluate the claim.
According to the phase rule we have F= C-P+2
In this particular situation, the forms are completely allotropic .In order words, they are conjured through the same chemical composition. Thus constituents C= 1, P=4 for four phases and the number variables is 2. As a result, F= C-P+2 =1-4+2= -1. Therefore, the claim is untrue.
