at 30°C 80 g of sodium nitrate is dissolved in 100 g of water is a solution saturated and unsaturated or supersaturated

Consider the resonance structures of formate. the first lewis structure of formate has a central carbon atom. a hydrogen atom an

OleMash [197]

So,

Formate has a resonating double bond.

In molecular orbital theory, the resonating electrons are actually delocalized and are shared between the two oxygens. So the carbon-oxygen bonds can be described as 1.5-bonds (option B). I'm not sure if option C is correct, however, because the likelihood of both delocalized electrons being in the area of one oxygen atom is less than 50%.

Which statement correctly identifies the nuclide that is most likely to be unstable and describes why?

iVinArrow [24]

The answer would be B.

U-238 has a n to p ration of 1.6:1. 146 neutrons and 92 protons.

It is actually the most commonly used isotope is reactors.

C-14 is also a radioactive isotope with 8 neutrons and 6 protons.

The usual and ideal n to p ratio is 1:1 such as C-12 or Mg-24

Balance this chemical equation.

Vadim26 [7]

Answer:

Explanation:

Reaction Given

NaHCO₃ (s) + HC₂H₃O₂ (aq) -------> CO₂ (g) + H₂O (l) + NaC₂H₃O₂ (aq)

Balance Equation = ?

Solution:

Balance Chemical Equation:

A balanced chemical equation is that in which the number of the reactant atoms equal to the number of the product atom.

For example if the carbon at the reactant side is 3, the number of carbon must be 3 on the product side.

Check the chemical equation and count the number of atoms at the reactant side and product side.

If the number of atoms of the reactants equal to the number of atoms of products then the reaction is balanced but if not equal then reaction is not balanced

Balancing is an trial and error process to get a balance reaction.

First we count the number of atoms of reactant and product

Number of atoms of Reactant:

Na = 1

O = 5

H = 5

C = 3

Number of atoms of Product:

Na = 1

O = 5

H = 5

C = 3

So this a balance equation as the atoms of the reactant atom equal to the number of the product atoms.

Na atom is 1 on both reactant and product side

Oxygen atoms are 5 on reactant and 5 on product side

hydrogen atoms are 5 on reactant and 5 on product side

Carbon atoms are 3 on reactant and 3 on product side

So all the compounds in the reaction have 1 as its coefficient in the blanks

1 NaHCO₃ (s) + 1 HC₂H₃O₂ (aq) -----> 1 CO₂ (g) + 1 H₂O (l) + 1 NaC₂H₃O₂ (aq)

PLEASE HELP!!!!!!!!!!!!!!!!!!!

Alborosie

Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

<h3>What is change of state?</h3>

Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.

In the graph shown above, water exists in three states at different points.

Water exists as a solid at A
Water exists as a liquid at B
Water exists as a gas at C.

Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.
