Answer;

C) 228/90Th

Explanation;

-The above nuclear equation shows a beta radiation. The nuclide X undergoes beta radiation to form 228/89 Ac.

- When an unstable nuclide undergoes beta radiation the mass number remains the same while the atomic number is increased by one.

-Therefore, we can get the mass number and the atomic number of nuclide X, The mass number would be the same as 228 (its not affected by beta radiation) and the atomic number would be 89 (88+1).

D. 

If it helps, try thinking of it like a simple math equation
Ac + the beta particle = X
so 228+0 and 89+-1 will give you the 228 over 88 which is Ra

What is the net ionic equation for a reaction between HCl and NaOH
kodGreya [7K]

Answer:

What is the net ionic equation for a reaction between HCl and NaOH?

Explanation:

A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl

Hope that helped.

Which change favors the products in this reversible reaction n2o4(g)+58 kj 2no2 (g)?
Ksenya-84 [330]

<span>According to Le Chatelier's Principle, the position of equilibrium moves to counteract the change, the position of equilibrium will move so that the concentration of products of chemical reaction increase, if:</span>

<span>1) increase temperature, because this endothermic reaction.</span>

<span>2) increase concentration of reactant.</span>

<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>
