Answer:
3
Explanation:
Nonmetals are only on the right side (other than hydrogen of course).
Malleable means to be able to be hammered out of shape with no cracking and luster is shiny (metallic properties)
Most likely a transition metal
Answer:
6.6023g
Explanation:
To create a 0.247 M solution required weight of barium hydroxide.
0.247 x 171.346 =42.322g per liter
Therefore required mass for 156g of water = 42.322 x 0.156 = 6.6023g
Density = Mass / Volume
V = 1.00 * 4.00 * 2.50 = 10 cm³
22.57 g/cm³ = Mass / 10 cm³
M = 22.57 g/cm³ * 10 cm³
M = 225.7 g
Answer: The mass of the block of osmium is 225.7 g.
I dont know you properly find your answer on google its so easy to get it from there good luck
Answer:
![Kc=\frac{[HI]^2}{[I_2][H_2]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BI_2%5D%5BH_2%5D%7D)
Explanation:
Hello there!
In this case, for these equilibrium problems it is firstly necessary to know the balanced reaction at equilibrium:
H2((g) + I2(g) ⇋ 2HI(g)
Next, by means of the law of mass action, it turns out possible for us to write the required and correct expression for the equilibrium constant by considering the concentrations and the coefficients in the aforementioned reaction:
Best regards!
