The symbol P is for phosphorus having atomic number 15. That means it has 15 protons and 15 electrons in its neutral state.

The given symbol P^{3-} has a -3 charge that means it has gained 3 electrons so, the number of electrons in the P^{3-} is: 15+3 = 18. The number of protons will remain same that is the number of protons = 15.

So, the ion P^{3-} has 15 protons and 18 electrons that gives 15-18=-3 charge on the P^{3-} ion.

So, the answer is 15 , 18.

Assume a density of water of 1.00 g/mL, and calculate the mass of water in the solution
tiny-mole [99]

Answer:

1g or 10^-3kg

Explanation:

as you know , the density =mass \volume

so  you have the mass from the number it self

<h2>\frac{1g}{1 ml} so from this equation, you will get 1 g and you can to SI to be 10^{-3}kg</h2>

How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams from 0.0 to 100.0
Luba_88 [7]

Answer:

Q = 19255.6 j

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Given data:

Mass of water = 46 g

change in temperature = ΔT = 100-0.0 = 100 °C

Heat absorbed by water = ?

Solution:

Specific heat capacity of water = 4.186 j/g. °C

Q = m.c. ΔT

Q = 46 g×4.186 j/g. °C×100 °C

Q = 19255.6 j
