Answer:
1.4 * 10^-3
Explanation:
The equilibrium expression can be written as follows:
Keq = P [HD]^2/[ P[H2] * P[D2]]
Where P is pressure
1.80= (2.7 * 10^-3)^2 / ( 1.1 * 10^-3 * P[H2])
P[H2] = [2.7 * 10^-3]^2 / [1.8 * 1.1 * 10^-3]
P[H2] = 1.4 * 10^-3 atm
The simplest way to use the periodic table to identify an element is by looking for the element's name or elemental symbol. The periodic table can be used to identify an element by looking for the element's atomic number. The atomic number of an element is the number of protons found within the atoms of that element.

A combination reaction (also known as a synthesis reaction) is a reactionwhere two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form: X + Y → XY.

To make molar NaCl solutions of other concentrations dilute the mass of salt to 1000ml of solution as follows:
0.1M NaCl solution requires 0.1 x 58.44 g of NaCl = 5.844g.
0.5M NaCl solution requires 0.5 x 58.44 g of NaCl = 29.22g.
2M NaCl solution requires 2.0 x 58.44 g of NaCl = 116.88g.
