$\\ \sf\longmapsto {}^{88}_{38}Sr^{2+}$

As 2 electrons are donated Hence the No of electrons =38-2=36

$\\ \sf\longmapsto {}^{51}_{23}V^{3+}$

As 3 electrons donated the no of electrons=23-3=20

$\\ \sf\longmapsto {}^{55}_{26}Fe^{3+}$

No of neutrons=55-26=29

$\\ \sf\longmapsto {}^{112}_{48}$

As 2 electrons are donated no of electrons =48-2=46

$\\ \sf\longmapsto {}^{210}_{82}Pb^{2+}$

No of neutrons=210-82=128

Explain how the relative atomic mass and the mass number of elements are different and hence why some elements have relative ato

padilas [110]

This is because the relative atomic mass is the sum of the no of protons and neutrons while the atomic no is of the former only. it is not a whole number it is th average weighted masses of the various isotopes of the element multiplied by their corresponding relative abundance. pls thank me and mark me briniest

A 40 g sample of water absorbs 500 calories of energy, how much did the water temp changed?

Dafna1 [17]

2.99 °C is the change in temperature if a 40 g sample of water absorbs 500 calories of energy.

<h3>What is specific heat capacity?</h3>

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Given data:

m = 40 g

Q = 500 J

Specific heat capacity of water = 4.18 J/g°C

Change in Temperature =?

The formula for Heat Energy is given by:

Q = mcp∆T

where: Q - Heat Energy

m - mass

cp - specific heat

∆T = change in temperature, $T_2 - T_1$

Solution:

Substituting the value of m, specific heat capacity of water and Q in the formula,

500 J = (40 g)(4.18 J/g°C)(∆T)

∆T = 2.99 °C
