True The positive electric charge of a proton is equal in magnitude to the negative charge of an electron; therefore, the net electric charge of an ion is equal to its number of protons minus its number of electrons. Ions are highly reactive species.
METALS ARE MAGNETIC(and maybe metalloids)
From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)
<h3>The features of different states of Matter:</h3>
Matter is defined as anything that has weight and occupies space.
There are three states of matter that is in existence which include:
- Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.
- Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.
Therefore, a liquid occupies the shape of its container.
- Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.
Therefore, a gas neither has a definite shape nor volume.

Answer: low temperature
Explanation:-
S.I or M.K.S is a system for defining physical units as meter, kilogram, second, ampere, kelvin or celcius, candela, and mole together with a set of prefixes to indicate multiplication or division by a power of ten for measuring length, mass, time , current, temperature and amount of substance respectively.
Given :
lake length = 563 kilometers = 
High temperature =
Low temperature =
annual precipitation =762 mm= 
Thus low temperature in units of Fahrenheit is not an S.I unit of measurement.
Answer:
his is an example of a first-year chemistry question where you must first convert two of the pressures to the units of the third and add them up, per Dalton’s law of additive pressures. There are three possible answers, one for each of the three pressure units.
1 atm = 760 torr …… torr and mm Hg are the same
1 atm = 101.3 kPa
Dalton’s law:
P(total) = P(O2) + P(N2) + P(CO2)
Explanation:
Gases will assume whatever pressure depending on the equation of state of the mixture (in this case) and the volume htey are contained in. That could be the ideal gas law and simple mixing law, If you are quoting the partial pressures which you call simply “the pressure” of each gas, and that these refer to their values in the present mixture, then yes, we would add them up. The pressures are low enough for the ideal gas law to apply provided the temperature is not extremely low as well .
