Melting Point: 155 °C (311 °F; 428 K)
Explanation:
The melting point of ammonium phosphate is 155 °C (311 °F; 428 K). The melting point is the temperature at which a compound will melt.
It is a physical property of most substances usually determined in the laboratory.
- Most solids, especially ionic salts have very high melting points.
- Ammonium phosphate is no exception.
- It is one of the key ingredients used in making plant fertilizers to ensure they grow properly.
- It is a white grain substance.
- It is an unstable compound made up of ammonium and phosphate salts.

The answer is C24H42O21. Lack of hydration responses shapes covalent bonds between two monomers by the arrival of a water particle. Every monomer taking an interest in the bond discharges either a hydroxyl amass (- OH) or a hydrogen (H) for each bond shaped. Connecting four glucose monomers requires three covalent bonds. This outcome in the loss of three particles of water or six hydrogen molecules and three oxygen iotas.
Answer: <em>Running water, even at a trickle, helps prevent pipes from freezing. If you decide to use fuel-burning equipment, such as a kerosene heater, ensure it is vented to outside and kept clear of any vents. Keep garage doors closed if there are water supply lines in the garage.</em>

Answer:
8.75 mL
Explanation:
First, we calculate the molar mass of NaCl = molar mass of Na + molar mass of Cl. Molar mass of Na = 23 g/mol, molar mass of Cl = 35.5 g/mol.
So molar mass NaCl = (23 + 35.5) g/mol = 58.5 g/mol. The number of moles ,n of NaCl in 12.5g is n = mass of NaCl/ molar mass NaCl = 12.5 g / 58.5 g/mol = 0.214 mol.
The molarity, M of 150 mL M = number of moles/ volume = 0.214 mol / 150 mL = 1.427 M.
We now calculate the number of moles of NaCl in 250 mL of 0.500 M.
Number of moles, n = molarity × volume. molarity = 0.500 M, volume = 250 mL. So n = 0.500 × 250 = 0.125 moles. Since we have 0.125 moles in the dilute 250 mL solution, the volume of the 150 mL 1.43 M solution required is number of moles in 250 mL solution/molarity of 150 mL solution = 0.125 mol / 1.427 M = 0.0875 L = 8.75 mL
