Answer:
The volume of the water after it freezes (at 0°C) is 354.4 mL.
Explanation:
We need to use this additional information, the densities of liquid water and ice at 0 °C are 1.000 g/mL and 0.917 g/mL, respectively.
Step 1. Find the mass of water before it freezes.
Step 2. The mass does not change when the temperature does. So, you take the grams of water and divide it by the density of the ice to obtain the volume it occupies.
Answer:
Interphase

Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.
Explanation:
Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.
As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.
Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.
As a result, silver chloride is not able to conduct electricity.
The answer is B. bases measure below seven
think of it like this 7 is neutral going down from seven it rises in acidity and going up from seven increases in alkalinity
The number of protons, neutrons, and electrons that iron (Fe) have if it has a +4 charge are 26, 29 and 22 respectively.
<h3>How to calculate proton, electron and neutron numbers?</h3>
Atomic number of an element is the number of protons in the atom of that element. The number of protons of a neutral atom i.e. charge 0 is equal to the number of electrons.
Iron is a metallic chemical element having atomic number 26 and symbol Fe. Since the atomic number is 26, the number of protons is 26.
If the charge of the iron is +4, this means that the number of protons will be 26 while the number of electrons will be 22. The number of protons will be 55 - 26 = 29.
