I think the name for it due to research online is Phosphide
Answer:
50.9° (corrected to 3 significant figures)
Explanation:
Energy(J) = mass(kg) x specific heat capacity x temperature change
(E = mcΔT)
Let the new temperature be T.
75000 = (1.2 )(4186)(T-36)
14.930 = T -36
T = 50.9°
<span>Weight of CaC2 is 1.53 g
Temparature is 23 celcius T = 23 + 273K = 296K
The pressure of the gas P = 755 torr
Calculating the moles of CaC2 n = 1.53g x 64.0994 mol/g = 0.023869 moles
PV = nRT
V = nRT / P => V = (0.023869 mol) x (62.3636 L Torr / K mol) x (296 K) / 755 torr
Volume of C2H2 = 0.587 L</span>
Since SeO2 dissolves in water to produce selenium acid, it is regarded as an acidic oxide.
The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. 350 °C (662 °F; 623 K). The chemical compound having the formula SeO2 is known as selenium dioxide. One of the forms of selenium that is most frequently seen is this colorless solid. It serves as a catalyst, reagent, oxidizing agent, and antioxidant in lubricating oils. OSHA regulates selenium oxide; thus, it is listed on the Hazardous Substances List. It can be produced chemically by dehydrating selenous acid or chemically by burning selenium in oxygen, nitrogen dioxide, or hydrogen peroxide.

When you dissolve an ionic compound into water, the have a tendency to separate from each other. They're still chemically the samething.
LiOH is an ionic compound. Lithium is positive and "borrows" the hydroxide's negative charge to be neutral & vice-versa. When LiOH is dissolved in water the Lithium and the hydroxide separate into their respective forms, also known as ions.
So, LiOH dissolves to become these ions in solution= Li+ and OH-
(the plus and minus represent their charges).
Hope that helps!
