Answer:
A
Explanation:
solute- thing being disolved
solvent- thing doing the disolving
so water is a solvent and salt is solute.
which is A
if my answer helps please mark as brainliest.
In the solution of salt and water, Water is the solvent; Salt is the solute. That is option A.
What is a solute and a solvent?A solute is defined as the part of a solution that is being dissolved by the solvent. A typical example of solute is base and salts.
A solvent is defined as the dissolving part of a solution which is usually liquid in form. A typical example is water.
Therefore, the solute and solvent of a solution would be salt and water respectively. That is option A.

How many moles in 5.125g of NaCl? In equation form!
Plzzzz! HELP ME!
Answer:
0.088mole
Explanation:
Given parameters:
Mass of the compound = 5.125g
Unknown:
Number of moles = ?
Solution:
To solve this problem, we need first find the molar mass of the given compound.
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
So;
Number of moles = [tex]\frac{mass}{molar mass}[/tex] = [tex]\frac{5.125}{58.5}[/tex] = 0.088mole

Answer:
The object is moving away from the origin
The object started at 2 meters
The object is traveling at a constant velocity
Explanation:
Statements which best describe motion of object represented by graph are statement A,D and E.
What is motion?Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.
Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.
Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic mechanics is based on modern kinematics.

Which of the following describes a covalent bond?
Answer:
It is the sharing of electrons between atoms with an electronegativity difference below 1.7.
Explanation: Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond.
Answer: Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.
Explanation: A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

Describe two patterns in the periodic table?
Answer:
Patter 1: Ionization Energy Decreases going down a group
Pattern 2: Ions tend to gain/lose the least amount of electrons
Take oxygen, for example. Oxygen has 8 electrons. To become like a noble gas it could either gain two to become like neon or it could lose six to become like helium. So what will oxygen do—gain two or lose six? As a general rule, atoms will gain or lose the fewest number of electrons possible.
