Gravity relates to a stream's ability to erode and deposit material by causing water to flow faster down a steep slope. True or False

Explanation:

In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.

Explanation:

lithium has group 1 elements and it valance electron has 1

so it more react with group 7 to be more stable

Answer:

Exothermic

Explanation:

Bond strength has everything to do with the energy associated with it. What I mean by that, is a stronger bond will require a lot higher of an energy input to break than a weaker bond.

In the same way, energy is released when a bond is made. So, the formation of a stronger bond releases more energy than the formation of a weaker bond.

So, putting the two ideas together, if the bonds formed as stronger than the bonds broken, then more energy is released than taken in, which means energy is released overall over the course of the reaction. This means that the reaction is exothermic.

If there was energy taken in overall, this would be an endothermic reaction.

Let me know if that makes sense, and hope I helped! :)

Exothermic reaction is a reaction in which the bonds formed during the reaction are stronger than the bonds broken.

When chemical reactions occur, there will always be an accompanying energy change.

In exothermic reaction the bonds formed in the products are stronger than the bonds broken in the reactants whereas in endothermic reaction the bonds broken in the reactants are stronger than the bonds formed in the products.

Answer:

Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,

Explanation:

so it becomes negatively charged.

Negative ions (or anions) are atoms that have gained electrons.

Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

Which statement about exothermic reactions is TRUE?

A.In an exothermic reaction, energy is absorbed, bonds are broken, and the temperature decreases.

Answer:   Mg²⁺   &  N³⁻

Explanation:

Since Magnesium is in group 2, then it favors losing two electrons forming a cation with a charge of +2 ( Mg²⁺).

Since Nitrogen is in group VA, it favors gaining three electrons forming the anion with charge -3 (N³⁻).

Explanation:

atomic no. is 42

chemical symbol is Mo

no. of protons is 42

atomic mass is 95.95

no. of electrons is 42

no. of electron in outer most shell is 1

no of electrons in the n 3 shell is 18

no. of neutron is 96

The element molybdenum is 42nd element in periodic table with the symbol Mo and  a mass of 96. It have 42 electrons and 42 protons.

Molybdenum (Mo) is a transition metal in periodic table included in the d-block. The atomic number of molybdenum is 42 which is the number of protons and electrons in it.

The atomic number of a neutral atom is equal to the number of electrons in it. For a neutral atom the number of electrons and protons are equal and thus the number of both electrons and protons in Mo is 42.

Mass number is the sum of number protons and neutrons in an atom. The mass number of Mo is 96 and number of protons is 42. Thus, the number of neutrons is 96 -42 = 54.

The outer shells of Mo are 4d and 5s containing 4 and 2 electrons respectively. Thus the number of outer electrons is 6.The level n= 3 is M shell which contains 18 electrons for Mo.
