It is impossible to divide an atom into smaller parts.
There are electrically neutral particles inside atoms.
Atoms contain small, negatively charged particles.
Answer: The correct statement is atoms contain small, negatively charged particles.
Explanation:
J.J.Thomson was a scientist which discovered electrons that are present in an atom.
He did an experiment and gave a model for this. The experiment conducted by him was Cathode Ray experiment and the model given by him was Plum pudding model.
From cathode ray, he showed that the cathode ray was composed of a negatively charged particles and named it as electrons. From plum pudding experiment, he said that the electrons are embedded in the atom. These particles carry negative charge and are very small as compared to the atom.
Hence, the correct statement is atoms contain small, negatively charged particles.
How much CaCl2, in grams, is needed to make 2.0 L of a 3.5M solution?
b. because they both start and end with diatomic (two-atomed) molecules
c. because they both start and end with the same types of particles
d. because they both start and end with two sets of particles eliminate
Why does the chemical reaction seen here obey the law of conservation of matter?
Answer:
Explanation
NaOH + HCl -----> NaCl + H2O
Answer:
the net ionic equation is H+(aq) + OH-(aq)----->H2O(l)
Explanation:
In conclusion to the earlier solution, 2H+(aq) + 2OH-(aq)----->2H2O(l) can be broken down because they all have the same coefficient. So divide both sides by 2.
The net ionic equation will be H+(aq) + OH-(aq)----->H2O(l)
The balanced molecular equation for the neutralization reaction between Hydrochloric acid (HCl) and Strontium hydroxide (Sr(OH)2) is HCl(aq) + Sr(OH)2(aq) -> SrCl2(aq) + 2H2O(l). Its net ionic equation is 2H+(aq) + 2OH-(aq) -> 2H2O(l). Spectator ions are eliminated during the formulation of the net ionic equation.
A neutralization reaction between hydrochloric acid and strontium hydroxide can be represented by the balanced molecular equation: HCl(aq) + Sr(OH)2(aq) -> SrCl2(aq) + 2H2O(l). Breaking it down into the total ionic equation we will have: H+(aq) + Cl-(aq) + Sr2+(aq) + 2OH-(aq) -> Sr2+(aq) + 2Cl-(aq) + 2H2O(l). This can be simplified by removing the spectator ions to obtain the net ionic equation: 2H+(aq) + 2OH-(aq) -> 2H2O(l). This aligns with the principle that in a neutralization reaction, an acid reacts with a base to form water and a salt.

b. have better 6 benefits in relationship to heart disease
c. increase its flavor
d. create a fatty acid
The answer is (a.) more solid
Adding hydrogen atoms to an unsaturated fatty acid will make it more solid. This process is called hydrogenation. In this process, hydrogen is added to an unsaturated fatty acid to make it more saturated and thereby more solid at a room temperature.
