What else can I help you with?
Whuch of the following are classified as an electron group?
Lone-pair electrons, Bonded pairs of electrons
Do action-reaction forces always occur in threes or pairs?
Pairs!
Why are homologous pairs called tetrads?
Homologous pairs are called tetrads because these pairs are maid up of a four-part structure. Tetrad literally means a group of four.
What are binary ionic compounds made of?
Some molecules (not just ionic compounds) always tend to come in pairs. Aluminum oxide for example Al2O3 always comes in a pair Al4O6, the empty electron pairs on the Aluminum making attractive sites for the filled electron pairs on Oxygen to 'stick' to.
Should BH3 and NH3 have the same shape?
NH3's shape is trigonal pyramidal, which has 1 e lone pairs and 3 bonding pairs, while BH3's shpe is trigonal planar, with 0 e lone pair and 3 bonding pairs. It's the force that electron lone pairs exert that pushes the molecules further and the repulsion force of lone pairs that aided in changing the shape of the molecules. Hence, the shape are different ...
Which pairs of substance will form a buffer when mixed in equal concentrations?
CHOOH and NaCHOO
When the carbonate acid sodium bicarbonate buffer pairs buffers a base?
water is produced
Assume that a section of double-stranded DNA contains 100 base pairs If 40 of the pairs contain base c how many pairs would contain base a?
If there are 40 pairs containing base C, the remaining pairs must contain the complementary base, G. Since each base pair must contain one A and one T (complementary to each other), the number of pairs containing base A would be the same as the number containing base T. Therefore, there would be 60 pairs containing base A.
Is na2hpo4 and nah2po4 a buffer?
Yes, a mixture of Na2HPO4 (disodium hydrogen phosphate) and NaH2PO4 (sodium dihydrogen phosphate) can act as a buffer solution. This is because they are conjugate acid-base pairs, allowing the solution to resist changes in pH when small amounts of acid or base are added. The ratio of these two compounds can be adjusted to achieve a desired pH, typically around 7.2 to 8.2, making it useful in biological and chemical applications.
What pairs separate unwanted substances out of the blood?
Kidneys
Why do imaginary solutions come in pairs?
Yes, they do. If a+bi is a solution, a-bi is also a solution.
What is a series of base pairs that controls what substances the cell makes?
\gene
Substances with lone pairs on central atom?
Ammonia (NH3), water (H2O), and hydrogen sulfide (H2S) are examples of substances with lone pairs on the central atom. These lone pairs play a key role in determining the molecular geometry and chemical properties of these molecules.
According to the rules of complementary base pairing a nucleotide containing the base cytosine would pair with a nucleotide containing the base of?
The base cytosine pairs with guanine via three hydrogen bonds. They are complementary base pairs in the DNA double helix.
What is the solution to the ditloid 23 p of c?
23 Pairs of Chromosomes (in a Human Body)
Number of sugar molecules in DNA section containing 3 base pairs?
A DNA section containing 3 base pairs would have 6 sugar molecules. Each nucleotide in DNA contains a deoxyribose sugar molecule, so 3 base pairs with 2 nucleotides each would have a total of 6 sugar molecules.
Which pairs of substances result in the destruction of the ozone in the stratosphere?
CFC's result in ozone destruction. They react with ozone and deplete it.
