7 0

Answer:

110V

Explanation:

Given parameters:

Current in the lightbulb  = 0.5A

Resistance  = 220Ω

Unknown:

Voltage  = ?

Solution:

To solve this problem, we apply the equation derived from ohm's law;

          V  = IR

So,

       V = 0.5 x 220  = 110V

An Element X has been discovered. Element X forms an Xt ion and
DanielleElmas [232]

<u>Answer:</u> The chemical symbol of the compound formed is XCl or NaCl

<u>Explanation:</u>

An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).

The element losing electron (metal) forms a positive ion known as a cation while the element gaining electron (non-metal) forms a negative ion known as an anion.

Element X has the atomic number 11 which is sodium. The electronic configuration of it is 1s^22s^22p^63s^1

This element will lose 1 electron to form X^+ ion of Na^+

Chlorine has the atomic number 17. The electronic configuration of it is 1s^22s^22p^63s^23p^5

This element will gain 1 electron to form Cl^- ion

When these two ions combine, they lead to the formation of an ionic compound having a chemical formula of XCl or NaCl

Hence, the chemical symbol of the compound formed is XCl or NaCl

What is the temperature of 4.5 moles of a gas that occupies 50. mL at 1.35 atm?
devlian [24]

Answer:

T = 0.182 Kelvin

Explanation:

As we know that

PV = nRT\\

Where P is the pressure in atmospheric pressure

T is the temperature in Kelvin  

R is the gas constant  

V is the volume in liters

R = 0.08206

Substituting the given values in above equation, we get -

1.35 * \frac{50}{1000}= 4.5 * 0.08206* T\\

On rearranging, we get

T = \frac{1.35*50}{1000*0.08206*4.5} \\

T = 0.182 Kelvin
