How many milliliters of a 4.0-molar solution

HCl + NaOH → NaCl + H2O

No. of moles of NaOH = MV/1000

= 3.2X60/1000

= 0.192 mol

**M is your concentration of solution, V is the volume of solution either in cm³ or mL cuz they are equal**

1 mol of NaOH reacted with 1 mol of HCl. No. of moles of HCl needed to react with 0.192mol of NaOH

= 0.192x1/1

= 0.192mol

Volume of HCl = no. of moles x 1000 / M

= 0.192 x 1000 / 4.0

= 48mL

What is the volume when the density is 7.83g/ml and 19.6 grams?

insens350 [35]

To fine volume, you have to divide the mass by the density of the substance. in this, you’ll do 19.6/7.83=2.50

How is the electron cloud model different from Bohr's atomic model?

Vesnalui [34]

Answer:

While Bohr's atomic model hypothesizes that electrons move in particular energy levels around the nucleus, the electron cloud model suggests that electrons move in an unpredictable pattern but are more likely to be in certain regions than others.

39. Analyze What subscripts would you most likely use if

Igoryamba

Based on their valencies, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2

<h3>What subscripts would you most likely use if the following substances formed an ionic compound?</h3>

A. An alkali metal and a halogen.

An alkali metal and a halogen both have valencies of one.

Therefore the subscripts would be 1.

B. An alkali metal and a non-metal from group 16.

An alkali metal has a valency of 1 and a group 16 non-metal has a valency of 2.

By exchange of valencies, the subscript would be 2 and 1.

C. An alkaline earth metal and a halogen.

An alkaline earth metal has a valency of 2 and a halogen has a valency of 1.

By exchange of valencies, the subscripts would be 1 and 2.

D. An alkaline earth metal and a non-metal from group 16.

An alkaline earth metal has a valency of 2 and a non-metal from group 16 has a valency of 2.

By exchange of valencies, the subscripts would be 2 and 2.

Therefore, the subscripts of the ionic compounds formed will be:

1 and 1
2 and 1
1 and 2
2 and 2

Is Helium a compound,element, or.mixture

dusya [7]

Answer:

element

Explanation:

we know that helium is a pure substance although helium atoms are sometimes mixed with their isotopes it is still the same element. since there is no other element combined with helium this makes it an element.
