Answer: In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged. ... Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.
Answer: an organic base, a phosphate group, and a sugar
Explanation:
A nucleotide is made up of 3 parts. We know a nucleotide is not made up of water so we are left with 2 choices. Nucleotides are made up of phosphate group, 5-carbon sugar, and nitrogenous base. The nitrogeneous base is typically adenine. The answer choice that matches this the closest is an organic base, a phosphate group, and a sugar.
The organic base is the nitrogeneous base and the sugar is the 5-carbon sugar.
B) When describing very dilute solutions.
Explanation:
The most appropriate time to use ppm is when describing dilute concentrations of solutes in solutions. It is used mostly to determine trace amount of elements in water and soils.
- The part per million ppm is the amount of miligram of a solute in a liter of solution.
- It is similar to percentage.
- Minute and trace concentrations are very difficult to work with.
- Using parts per million, they become better appreciated and easy to use.

Answer:
4
Explanation:
In a rate law, The reaction order is basically the superscript (power) of the concentration of the reaction. It defines the extent to which the rate of the reaction depends on the concentration of the reaction.
In this rate law, the order of the reactants are;
[BrO3] = 1
[Br] = 1
[ht] = 2
The overall reaction order is the sum total of the individual orders. We have;
1 +1 + 2 = 4
Answer is: Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.
For example, nitrogen molecules have weakest intermolecular bonds in gas phase and move fast and without order.
Cooling is change from liquids to solids. In solid state (for example ice) movement of molecules is more slow than movement of molecules in liquids (for example water).
In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container.
Liquids have definite volume, but no fixed shape.
Gases (for example nitrogen and neon) not have definite volume and fixed shape, it depends on its container.
