Answer:

Cu^2+ (aq) + S^2- (aq) --> CuS (s)

Explanation:

Break up all the soluble compounds into their constituent ions to get the complete ionic equation, and cross off the ones that appear the same on both sides:

Cu (aq) + 2Cl(aq) + 2Na (aq) + S (aq) --> CuS (s) + 2Na (aq) + 2Cl (aq)

2Cl and 2Na appear on both sides of the arrow, so cross those out to get the net ionic equation.

Which of the following statements is not true of alpha decay?
Ad libitum [116K]

Correct answer: A. Alpha particles are 20 times safer than other types of radiation.

Alpha, beta, gamma, and X-rays are the forms of ionizing radiations. Alpha radiations are emitted when an atom emits alpha particles with 2 neutrons and 2 protons. These particles ionize matter due to their charge and mass. Alpha particles cannot penetrate the outer layers of the skin, but when present inside the cell they can be very damaging as they lose their energy within short distances ionizing the matter present around. Therefore, alpha particles cause more damage than other forms of radiations.

Refer to the illustration of the periodic table to determine which formula is correct.
Mekhanik [1.2K]

Answer:

D. MgO

Explanation:

We need to look at the charge of element. (Look at a periodic table for this)

Mg, which is Magnesium, has a charge of 2+ because it's in the second column, or group, from the left.

O, which is Oxygen, has a charge of 2- because it's in the second column, or group, from the right.

Since Mg is 2+, it's the cation and since O is 2-, it's the anion. We can put these two elements together into an ionic compound.

Mg^(2+) and O^(2-) becomes Mg2O2, where we can cancel the 2s: MgO.

Thus, the answer is D.

Hope this helps!

Thermal energy chemical change lab report
natulia [17]

Answer:

This is required answer.

Explanation:

Given that,

Thermal energy chemical change lab report

We know that,

Thermal energy :

When we rise a temperature of any substance then the molecules of substance moves fastly then the heat produced. It is called thermal energy.

Chemical change in the thermal energy  :

When we heat a substance then the thermal energy increases and the molecules of substance moves fastly. That means the chemical bonds are break in reactants due to energy.

In products, The new chemical bonds are create due to energy.

For example ; The coal is burned then produced heats water and change it into steam.

Hence, This is required answer.
