I think so since in the universe there are other universes as well so maybe the might be even more space in space it is kind of confusing but it makes sense so yes the is space in space. Hope it helped pls give brainlyest

What are the two energy of the electrons outside the nucleus
ICE Princess25 [194]

Answer:

Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus

An object has a mass of 20 g and displaces a volume of 5 mL. What is the object's density?
lara [203]

Hey There!:

The density is the quotient between the mass of a material and the volume occupied by it, The density can be expressed for a substance or for a mixture of substances. For example, water density in ambient conditions is equal to 1.00 g/cm3, which means that in 1 cm³ or 1 mL, there are 1.0 g of water. Therefore:

D = m / V

D = 20 g / 5 mL

D = 4,0 g/mL

hope that helps!

How many milliliters of 2.19 M H2SO4 are required to react with 4.75 g of solid containing 21.6 wt% Ba(NO3)2 if the reaction is
Setler [38]

Answer:

1.7927 mL

Explanation:

The mass of solid taken = 4.75 g

This solid contains 21.6 wt% Ba(NO_3)_2, thus,

Mass of Ba(NO_3)_2 = \frac {21.6}{100}\times 4.75\ g = 1.026 g

Molar mass of Ba(NO_3)_2 = 261.337 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{1.026\ g}{261.337\ g/mol}

Moles= 0.003926\ mol

Considering the reaction as:

Ba(NO_3)_2+H_2SO_4\rightarrow BaSO_4+2HNO_3

1 moles of Ba(NO_3)_2 react with 1 mole of H_2SO_4

Thus,

0.003926 mole of Ba(NO_3)_2 react with 0.003926 mole of H_2SO_4

Moles of H_2SO_4 = 0.003926 mole

Also, considering:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity = 2.19 M

So,

2.19=\frac{0.003926}{Volume\ of\ the\ solution(L)}

Volume = 0.0017927 L

Also, 1 L = 1000 mL

<u>So, volume = 1.7927 mL</u>

Which of the following illustrates the conservation of matter? A. SnO2 + H2 --&gt; Sn + 2 H2O B. 2 C + O2 --&gt; CO2 C. KOH + HB
olga2289 [7]

C. KOH + HBr → KBr + H₂O

Explanation:

The two equations above illustrates the conservation of matter. The law of conservation of matters states that

               "in a chemical reaction, matter is neither created nor destroyed but transformed from one form to another".

By this law, we understand that the amount of a particular matter we are starting with should be the one we end with.

    KOH + HBr → KBr + H₂O

Conserving                          Product                          Reactants

     K                                         1                                           1

     O                                         1                                           1

      H                                         2                                          2

We can see that the amount on both sides are the same.
