I think the answer is ZnS
Answer: <span>A) can form hydrogen bonds.
Water has a high heat capacity. Water is also a good solvent since many things, mostly polar chemical compound, that can be dissolved using it. Water is definitely polar. Water structure is well known to be like "Mickey mouse", causing it to have a more positive pole at the side with Mickey's ears.
Water has hydrogen bond that was causing it has a high boiling point.</span>
Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
Answer: 32 kcal
Explanation:
Q= heat gained or lost
m= mass of the substance = 874.3 g
c = heat capacity of water = 1 cal/g ° C
Q= 32008.1cal=32..0kcal (1kcal=100cal)
Thus heat lost by 874.3 g of iron is = 32 kcal
Heat lost is represented as a negative sign.
P₁V₁ = P₂V₂
Convert 473ml > L
(1atm)(1.00L) = (0.473L)P₂
Divide by (0.473L)
Solve for 2.11atm
