Answer:
pH
7.0 = neutral.
(7–14) = basic
(0–6) = acidic
Explanation:
Answer:
True
Explanation:
The complete question is:
"A reaction contains two reactants, A and B. If A is doubled, there will be a greater number of effective collisions between reactants. TRUE FALSE"
Collision Theory indicates that chemical reactions take place because molecules, atoms or ions collide with each other.
Furthermore, the molecules must collide effectively, that is, not all reagent collisions lead to product formation. Effective shock means that the reagent molecules have enough kinetic energy at the time of the shock for their bonds to break and product bonds to form. In addition, the molecules of the reagents must be properly oriented for the reaction to take place.
As the concentration increases, the number of shocks increases. In other words, by increasing the concentration of the reactants, the probability of collision between their molecules increases, and therefore the number of effective collisions.So the statement is true-
Answer:
"It has five valence electrons available for bonding".
Explanation:
In DNA, the nitrogenous bases are represented by A for Adenine, T for Thymine, C for Cytosine, and G for Guanine. Adenine pairs with Thymine, and Cytosine pairs with Guanine, through hydrogen bonds.
In DNA, there are four nitrogen bases represented by the letters A (Adenine), C (Cytosine), G (Guanine), and T (Thymine). These bases form complementary base pairs, with A pairing with T, and C pairing with G. The bases are held together by hydrogen bonds, with A and T sharing two hydrogen bonds, while C and G share three. These bases are differentiated by their ring structures: Adenine and Guanine are double-ringed structures called purines, while Cytosine and Thymine are single-ringed structures known as pyrimidines. The pairing always occurs between one purine and one pyrimidine, which helps maintain the uniform shape and structure of the DNA molecule.

The name of the compound given in the question is nitrogen trifluoride.
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.
