Answer:

By gaining elections

Explanation:

Cations are formed when neutral atoms loss electrons and when they gain back the lost electrons the charges are neutralized.

Eg. Cu=Cu2+ + 2é

Cu2+ + 2é=Cu

A neutral atom contains the same number of electrons as protons and that means that the electric charge of the atom is neutral or otherwise known as zero. However, if a particular atom loses an electron, the atom becomes positively charged because there is more protons than electrons.
THIS IS CALLED A CATION.

How does the average temperature change as the latitude decreases from the poles to the equator

igor_vitrenko [27]

As the earth is in the form of a sphere, the angle of incidence of the sun's rays at the earth's surface increases from the equator towards the poles and therefore the amount of heat received on a GIVEN AREA diminishes in the same direction. Temperature is therefore normally hottest near the equator and coolest near the poles.

Why does an increase in reaction temperature generally increase the reaction rate?

zalisa [80]

Answer:

This is because an increase in temperature increases the movement of molecules/particles of reactants which encourages collision and subsequently, reaction.

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
