If an element forms a 3+ ion in which group of the periodic table would you expect to find it?A. 15
B. 5
C. 13
D. 2

Answers

Answer 1

Answer:

If an element forms a 3+ ion, one can expect to find it in group 13 of the periodic table (option C).

What is the periodic table?

Periodic table is a tabular chart of the chemical elements according to their atomic numbers so that elements with similar properties are in the same group (column).

The periodic table is made up of vertical columns called group and horizontal rows called periods.

Elements in group 13 form ions with +3 and +1 charges. The elements are as follows:

boron (B)
aluminum (Al)
gallium (Ga)
indium (In)
thallium (Tl)
nihonium (Nh)

Therefore, group 13 elements in the periodictable form +³ ions.

The volume of a gas is 605 liters at 27.0°C. The new temperature is -3.0°C. What is the new volume?-67.2 L
-545 L
-672 L
-5450 L

Answers

According to the Charle's law, the new volume of gas is -545 L when the pressure is constant.

What is Charle's law?

Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.

The graph of volume versus temperature is a straight line passing through the origin.It was formulated in the year 1780 by scientist Jacques Charles.

The new volume of gas is obtained by substituting values in the formula V₂=605×(-270)/300=-545 L.

Thus, the new volume of gas is -545 L.

from p1v1/t1 = p2v2/t2
pressure unchanged ... cancelled out
v1=605 , t1=27C = 300K,
t2=-3C = 270K
***remember temperature must be in Kelvin
we got
605/300 = v2/270
v2 = 545

The statement is absurd. A conducting material is called a conductor, not an insulator.

Each step in any energy conversion process will _____. gain energy create energy dissipate energy destroy energy

Answers

The correct answer is to dissipate energy. Each step in any energy conversion process will dissipate energy. The energy conversion is the process in which a form of energy is being converted into a new or another form of energy.

The correct answer to the question is : Energy dissipate.

EXPLANATION:

Before coming into any conclusion, first we have to understand law of conservation of energy.

As per law of conservation of energy, energy can neither be created nor be destroyed. It can only change from one form to another form, and the total energy of the universe is always constant.

As per the question, there is energy conversion. One form of any energy may be converted into various types of energy. One particular type of energy is not obtained always.

Hence, the correct answer to the question is energy is dissipated during energy conversion.

c. electric energy.
d. thermal energy.

What happens to the room temperature in ehich an air conditioner is lefy running on a table in the midle of the room

Answers

An air conditioner takes heat out of the air that runs through it. It has to put that heat somewhere. If it can't blow the heat out of the room then the heat stays in the room. But that's not all. While it's running the air conditioner also uses electrical energy to run. And that generates more heat. So if there's an air conditioner running in a closed room then the room will get warmer.

it will get cold only in that room. if you also have it in a room and close the door it will also get colder. sorry if this didnt help.

"a certain sprinkler releases water at the rate of 150 liters per hour. if the sprinkler operated for 80 minutes, how many liters of water will be released?"

Answers

The amount of water released is mathematically given as

V=200l

What is the amount of water that will be released?

Question Parameters:

a certain sprinkler releases water at the rate of 150 liters per hour.

operated for 80 minutes,

hours in 80min is

h80=80 minutes × (1 hour /60 minutes)

h80= 1.3333 hours.

Generally, the equation for the volume of water is mathematically given as

V=flow rate/time

V=150/1.333

V=200l

Final answer:

When a sprinkler releases water at a rate of 150 liters per hour, it will release 200 liters of water in 80 minutes.

Explanation:

This is a basic math problem involving units of measure and time conversion. The sprinkler releases water at a rate of 150 liters per hour. If it operates for 80 minutes, you will need to first convert the 80 minutes to hours since the rate is provided in liters per hour. 80 minutes is equal to 1.33.. hours (80/60 = 1.33..). Now, to find out how many liters of water will be released, multiply the hours by the rate of release. So, 1.33.. hours * 150 liters per hour = 200 liters. Therefore, the sprinkler will release 200 liters of water in 80 minutes.
