In a solution of salt and water, which component is the solute? A.
salt

B.
water

C.
beaker

D.
oxygen

Answers

Answer : The correct option is (A) Salt.

Explanation :

Solute : It is defined as a substance which is dissolved in a solvent. It is a smaller component of a solution.

Solvent : It is defined as a substance that dissolves a solute. It is a larger component of a solution.

In a salt and water solution, the solute is salt component and the solvent is water component.

Therefore, the correct answer is Salt.

The component of the solute is SALT.

Where would earth's be positioned during autumn if you lived in the southern hemisphere

Answers

Answer:

Autumn is one of the four basic seasons of the year in the temperate climate zone. It is characterized by moderate air temperatures with a decreasing daily average, and relatively high annual precipitation. The climate autumn is the period of the year in which the average daily air temperature ranges around 10° C.

Astronomical fall begins at the fall equinox and lasts until the winter solstice, which roughly means in the southern hemisphere between March 23 and June 22 (sometimes these dates are a day earlier or a day later, and in a leap year they may be additionally retracted one day). During astronomical autumn, the day time of the day is shorter than the night time, and moreover, with each successive day of the day it decreases and night increases.

Is CI3 a compound or an element

Answers

Cl₃ is formed by thecombination of 3 chlorine atoms. Hence, not a single element and not a compound. Instead Cl₃ is a molecule of chlorine.

What are molecules ?

Molecules are the combination of atoms of same element or are the basic units of a compound. A compound is formed by the combination of two or more atoms of different elements.

The combination of atoms can be different bond types, such as ionic bond, covalent bond, hydrogen bonding etc. The type of bond is dependent on the nature of atoms.

Combination of same atoms in any number are forming the molecules of that element and not a compound. Hence, Cl₃ is a molecules and not element or compound.

A baker touches a pie right after taking it out of the oven. Which statement best explains why the pie feels hot?

Answers

The pie is going to be hot right when it comes out of the oven because the oven uses air to transfer heat. The air warms at the bottom of the oven and the air rises to the top of the oven where your food is. This is why any food is going to be hot right after you take it out of an oven.

Answer:

Molecules in the pie move faster than molecules in the skin, so heat is transferred to the skin.

SELECT ALL THAT APPLYat STP conditions, 0.25 moles of CO2(g), H2(g), NH3(g)
1. Will contain the same number of molecules
2. Will contain the same number of atoms
3. Will occupy the same volume
4. Will have the same g.f.w

Answers

at STP conditions, 0.25 moles of CO2(g), H2(g), NH3(g)

The answers are:
1. Will contain the same number of molecules
3. Will occupy the same volume

Answer: The correct answer is Option 1 and Option 3.

Explanation:

We are given:

0.25 moles of $CO_2,H_2\text{ and }NH_3$

STP conditions states that 1 mole of a gas occupies 22.4 L of volume.

The volume occupied by all the gases at STP will be $0.25* 22.4=5.6L$

According to mole concept: 1 mole of a compound contains $6.022* 10^(23)$ number of molecules or 1 mole of an element contains $6.022* 10^(23)$ number of atoms.

We know that the given gases are compounds. Thus, all the three gases will have $0.25* 6.022* 10^(23)=1.5055* 10^(23)$ number of molecules.

Hence, the correct answer is Option 1 and Option 3.
